Question 4 has completed work on the draft new Recommendation H.351 (ex H.350.WI) Semantic Web Interface for Multimedia Terminal and System Directories (SWIM-D), and it was agreed to move it forward for Consent at this meeting. For enhancements of H.350 directory services, interested parties were encouraged to progress this work. For other new applications, Question 4 is open to proposals and contributions are welcome.
Question 5/16 Summary
Question 5/16 continued to make progress to address NAT/FW traversal issues related to H.323. At this meeting, we concluded work on a new H-series supplement Supplement to describe the use of proxy functionality as a means of facilitating the traversal of NAT/FW boundaries. We also made progress on new NAT/FW traversal specifications that will enable media to flow directly between two terminal devices, even if both H.323 devices are located behind NAT/FW devices.
Question 12/16 Summary
Question 12 made steady progress toward the development of requirements and architecture for the new Advanced Multimedia System (AMS). The experts of Q12 reviewed incoming liaison statements, reviewed the AMS project description, agreed upon new requirements for AMS, and agreed upon a skeleton framework for the AMS terminal architecture specification. We also initiated communication with other SDOs and ITU-T Study Groups in order to help progress the work and coordinate activities.
Question 13/16 Summary
Question 13/16 reviewed all the contributions to the meeting and updated the current draft Recommendation H.IPTV-MAP. It also created four new draft Recommendations, H.IPTV-SDC, H.IPTV-DSMW, H.IPTV-AEH, and H.IPTV-MD. Q13/16 had joint meetings with ISO/IEC JTC 1/ SC 29/WG11 (MPEG) on IPTV-related issues and ISO/IEC JTC 1/SC 29/Maintenance Task Force on ISO/IEC 13522 Series (MHEG) for the maintenance of T.172. It also held joint meetings with Q6/16 and Q23/16 to discuss documents on two FG IPTV deliverables: Toolbox for Content Coding and Application Layer Error Recovery.
Question 21/16 Summary
Q.21 discussed architecture aspects of multimedia application. After discussion based on contributions and liaison statements, it was agreed to propose draft new Recommendations H.ghna and H.mid for Consent at this meeting.
Remote management was discussed in the context of multimedia services and it was agreed to start a new study item on remote management (specifically concerning data model and use cases).
Networked ID including IP resolution protocol and Visual Surveillance are discussed jointly with Q.22/16. IPTV related issues were discussed as a part of IPTV-GSI.
Question 22/16 Summary
At this SG16 meeting, Q22/16 experts met for 7 sessions including four joint sessions with Q21/16. Question 22/16 discussed service awareness, NID, USN, and visual surveillance. Service awareness is one of the hottest spots for Q22/16, more than ten or so Ccontributions and documents were received and well discussed. As a result, the initial draft of F.MSATC (Scenarios and requirements for service awareness and traffic control) was created incorporating the contents of these Ccontributions. Visual surveillance discussion ended up with an updated version of F.VSreqs produced. Our work on F.771 (ex F.mid) and H.621 (ex H.mid, in coordination with Q21/16) progressed well so that these two draft Rrecommendations are ready for Cconsent. We also started our work on ID coding schemes and ID resolution protocols serving tag-based ID triggered multimedia information access with two new work items created. In the area of USN middleware, an initial draft for F.USN-MW (Service description and requirements for USN middleware) was prepared.
Question 24/16 Summary
Question 24 has completed work on the draft new H.361 Amendment 1 End-to-end quality of service (QoS) and service priority signalling in H.323 systems: New Annex A 'IntServ/RSVP support for H.323 Systems', Annex B 'DiffServ Support for H.323 Systems' and Annex C 'Priority Support for H.323 Systems'. It was agreed to move the H.361 Amendment 1 forward for Consent at this meeting. In addition, Question 24 created new work items including the analysis of existing home network QoS solutions and an adaptive QoE control framework based on variable bit rate codec in wireless networks.
Question 25/16 Summary
Q25/16 reviewed some matters in relation with multimedia security and advanced multimedia systems in NGN. In particular, H.235.6 was updated to allow support of 192 and 256 bits AES. Q25 proposed one Amendment and one Corrigendum for Consent (H.235.6 Amd. 1, H.460.22 Cor. 1).
Question 28/16 Summary
The goals for this meeting were to review the roadmap for telemedicine and discuss about further activities. It is agreed that the roadmap for telemedicine needs some improvements: basically, a more homogeneous structure and an updated list of standards from other SDOs as CEN, ISO, IEEE, etc. It was observed that those organisations were invited to do it through the eHealth Standardization Coordination Group (eHSCG) but few inputs were received. Two options are proposed: to allocate more resources to improve the roadmap or use one of the new existing roadmaps and start the ITU work from this point.
Question 29/16 Summary
In the context of NGN GSI, Question 29/16 has continued its cooperation with Question Q6/13 as well as Questions Q2 and Q5/19 on mobility related issues for NGN. A joint meeting together with Q6/13, Q2/19, and Q5/19 was held in Seoul 17-23 January 2008 (WP2/16 Rapporteur meeting joint with NGN GSI meeting). This cooperation supports Q.29/16 to progress its work on the technical paper TP.MMSM (Service Mobility mobility for new Multimedia multimedia Service service Architecturearchitecture), which was approved by SG 16 at its closing Plenary.

Liaison Statements considered by WP 2/16
WP 2/16 took note of the Liaison Statements received from other Study Groups or other standardisation bodies. Where appropriate, responses have been prepared, as listed in the §4. Some of the Liaison Statements had already been reviewed at the interim Rapporteur meetings listed in §3.2.1 and responses had been returned from there as contained in TD 396/Gen.
Draft Recommendations consented at the previous meeting in June-July 2007
Except for H.248.1 V3 Amendment 1, all the draft Recommendations were approved on 29 August 2007 with typographical corrections to H.248.9 Amendment 1. H.248.1 V3 Amendment 1 has been referred to the SG approval at this meeting. See TD 568/WP2 for further details.
SG 16 management offered an idea of holding teleconference between the IETF key person and Q3 experts as a possible way forward. This was sought during the two weeks, but not successful due to the schedule conflicts. Q3/16 proposed to approve H.248.1 V3 Amendment 1 without the updated package registration procedures. WP2 agreed on this proposal.

TD 513/Gen was reviewed and discussed during the joint Question 1 and 2 session.
General Q.1 topics
Video submode control
C.339 and C.408 was presented and discussed during the joint Q1 and 2 session.
H.320 session
Proposed extension to H.300-series far end camera control
C.399 was presented and the experts agreed that the limitation to FECC on the main video stream was no longer sufficient. With H.239 and the possibility of opening multiple logical channels in H.323, there is a need for controlling multiple cameras in different video streams. Experts agreed to the proposed addition of mcuNumber in terminalYouAreSeeingInSubPictureNumber and asked Q2 to add this parameter in H.245 v14. The proposal of adding a 2nd video channel to H.224 had merits, but experts felt that there should be a generic method of allowing FECC in a unlimited number of video streams. One idea presented was to add a video channel/source number parameter to H.281 to allow control of a camera in a particular video stream. Contributions to progress this work in a flexible extensible way are solicited. It was also mentioned that H.282 and H.283 could possibly be deleted to avoid confusing implementers on which FECC standard to use. Proponents of such deletion were asked to poll different Q1 and H.323 mailing lists to ensure that there are no deployed implementations of H.282/H.283 and bring a contribution with results to a future meeting.
H.324 session
LS on clarification of H.324 Use of FunctionNotSupported Message
TD 468/Gen was presented and a discussion followed. Experts agreed that FunctionNotSupported was not the correct reply to terminals that dont support, or have not implemented, procedures of H.245. B.14.11/H.245 describes the use of FunctionNotSupported. A LS reply, shown in TD 617R1/WP2, was prepared and Q1 agreed to send this reply to the IMTC 3G-324m AG.
Improved IMS-CS Video Interworking with MONA
TD 475/Gen, a LS from 3GPP, and C.417 were presented and a discussion followed. C.417 proposed a modification to the alternative 2 of the LS. Q1 experts thought that this problem needed to be investigated to ensure compatibility and take in account scenario such as when an entity in the middle launches 2 calls to 2 endpoints. It was also noted that they may be an inconsistency with the transmission of SPC MOS Request messages which the H.324 Editor will analyze. A LS reply, shown in TD 616R1/WP2, was prepared and Q1 agreed to send this reply to 3GPP with a copy to IMTC.
Draft revised H.324
TD 567/WP2 shows a draft revised H.324, but because of the open issue that we likely result in changes to Annex K, it was not presented. The revision was only incorporating text from Amd. 1 + 2 and Cor. 1 +2, and Consent was not required at this meeting.
T.120 session
Draft revised T.128
TD 593/WP2 was presented and the Q1 experts accepted the content of this draft. This draft incorporated the changes from TD 56/WP2 proposed by the TSB and the ASN.1 Project Group in November 2004. It was agreed to submit Draft revised T.128 for Consent at the closing Plenary. The final text appears TD 471/Plen.
H.310, H.321 session
Draft new Corrigendum 1 to H.222.0 | ISO/IEC 13818-1
TD 537/WP2 (Correction of zero_byte syntax element and stream_id_extension mechanism) was presented and the Q1 experts accepted the content of this draft. It was agreed to submit Draft Cor. 1 for Consent at the closing Plenary. The final text appears TD 472/Plen.
Items considered in joint Q1 & Q2 sessions
Video submode control
C.339 and C.408 were presented. C.408 contained some comments and a proposal to extend the applicability of submode messages proposed in C.339. The group agreed to create an Ad-hoc Group with the task of finalizing the text proposed and incorporate the comments/feedback received. The report of the AHG with proposed text for a new clause 6.2.5/H.241 and a new Appendix II appeared in TD 605/WP2. Q1 experts agreed with the text proposed in the AHG report and asked the editor to prepare a draft Amendment 1 for review. Draft Amd. 1, shown in TD 621/WP2 was reviewed and accepted. It was agreed to submit Draft Amd. 1 for Consent at the closing Plenary. The final text appears TD 490/Plen.
Regarding the H.230 codepoints mentioned in the draft, Q1 pre-assigned (000)[25] for the SBE and 0001 1101 for the MBE. Q1 agreed to add these submode messages to H.230 in the next revision (2009).
LS from Q7/12 on speech and audio coding matters
TD 513/Gen was reviewed and noted. The answers from the LS sent in July 2007 are still valid and no experts had any statistics on double talk to present. Conferencing systems assume that people tend to talk at the same time and this was already the conclusion of Q1 at the last meeting.
Items considered in joint Q1 & WP2 sessions
WP 2/16's Questions for the next study period
TD 541/WP2 and TD 542/WP2 were presented and discussed during the WP2 Questions session. Q1 was asked to add text reflecting climate changes and the following sentence was added: The use of technologies developed in this question, typically audio, video and data conferencing systems, improve communication quality and efficiency and contribute to a reduction of greenhouse gas emission when used as an alternative to travel.
Intellectual Property Statements

TD 514 LS on Question 223-2/8 "Internet protocol applications over mobile systems" [ITU-R SG5]
It was suggested that we send a liaison statement to inform ITU-R SG5 of the work we are doing on H.323 Annex I and extend an invitation to liaise with them to help support their work. The liaison appeared as TD 608/WP2. A number of editorial corrections were made and the final revised liaison appeared as TD 608R1/WP2.
TD 524/Gen LS on countering spam by technical means [SG17]
Refer to the Q25 meeting report.
H.323 System Implementors Guide
TD 595/WP2 Draft revised H.323 Implementors Guide [Editor]
Reviewed. The Implementors Guide was revised based on discussion during the meeting and appeared as TD 595R1/WP2.
It was agreed to put this document forward for approval. A revised version of the Implementors Guide was published as TD 520/Plen.
H.323
TD 563/WP2 Draft revised ITU-T Recommendation H.323 (Version 7) [Editor]
A few editorial issues were pointed out to the editor. Q25 updated H.235.6 Table 1 to show 192 and 256-bit key lengths for AES. As such, we agreed to update Table J.1 in H.323 to align with H.235.6.
A revised H.323 text appeared in TD 563R1/WP2.
In reviewing TD 563R1, it was noted that a media streams should read media streams in the definitions section of the document. It was noted in Annex R that there are references to Internet Drafts. We should decide whether those references are essential and, if not, remove them.
C.322 Opening Multicast Channels in H.323 - comments on AVD 3299 [Polycom, Cisco]
It was agreed to add this text to H.323v7 and H.245v15. An issue that was discussed was the fact that the generic multiplex capability could not be used. To address that, it was agreed to use a generic control capability to represent the single transmitter multicast capability. The input document was revised and provided as TD 618/WP2 and includes material for H.245v15.
H.225.0
TD 515/Gen LS on H.225.0 editorial observations [TTC]
It was agreed to accept these changes into H.225.0. Item #26 asked which form of the various representation of should be used and it was agreed that we would use for consistency, as it appears at the beginning of the third paragraph in IV.1.1.2.2.2.
The propose change #18 from TTC highlighted the fact that there are several places throughout H.225.0 where the word reason is bold and not bold. In places where it is bold, it is because the field name is reason. However, similar sentences do not have the word bold because the field name is rejectReason and there are some places where the field name is reason, yet the word still has a normal font weight. The H.225.0 editor was asked to make a pass through the document and change all occurrences of reason where it is bold to use a normal font weight in the case that the word reason is preceded by an article and other places where the field name is being used in bold where (in the editors view) it ought to have a normal font weight.
TD 560/WP2 Comments on H.225.0 [Rapporteur]
With regard to the first comment in this document, there was general agreement that it could be worded better in H.225.0. However, the proposed wording also left the experts feeling that it was not as clear as it could be. Further consideration on this should be given and contributions to propose better wording are solicited. The editor is also encouraged to consider how this text might be improved to clarify the text.
The second point highlighted the fact that we introduced a new mandatory element in various messages (Status, Status Inquiry, and Setup Acknowledge) that did not exist prior to H.323v4. It was agreed to add a Note 2 to tables 14, 15, and 16 for the user-user IE with wording that says, This element was not present in H.225.0 prior to H.225.0 (2000).
TD 594/WP2 Draft revised ITU-T Recommendation H.225.0 [Editor]
Presented. An updated draft that contained agreements from the meeting appeared as TD 594R2/WP2.
H.245
C.339 Video Submode Control [Israel]
Refer to the Q1 meeting report. An OID was added to H.245 based on this contribution.
C.399 Proposed extension to H.300-series far end camera control [Huawei]
It was agreed to accept the proposed change to H.245 at the end of this contribution.
C.408 Discussion of Video Submode Control [Tandberg]
Refer to the Q1 meeting report.
C.319 Proposed changes to draft new H.361Annex A "IntServ/RSVP support for H.323 Systems" [Cisco]
C.320 Proposed changes to draft new H.361Annex B "DiffServ Support for H.323 Systems" [Cisco]
C.321 Proposed changes to draft new H.361 Annex C Priority Support for H.323 Systems [Cisco]
The above three documents were reviewed in the Q24 meeting. There were ASN.1 changes agreed to be included in Recommendation H.245.
TD 632/WP2 - Text for H.245 version 14 [Editor]
In Table D.1, the Note from TSB should be modified to say a previous entry or otherwise modified to make it clear that this and the following capability appears a second time because the first two appearances of these capabilities had conflicting OIDs. Should the note be moved to the RFC 3389 table entry? The matter was left to the editors discretion.
In table VIII.1, the word in the OID set-submode-capability should be changed to set-submode.
Table VIII.1 needs to be updated to include OIDs from TD 478/WP2 (07/2007), which are OIDs related to H.324.
It was agreed to put H.245v14 forward for consent at this meeting. It appeared as TD 516/Plen.

ITU-T Restructuring and Q.3
Q3/16 discussed the status of Q3/16 in the next Study Period. It was noted that there have been some proposals to move Q3/16 to a different Study Group. The delegates of Q3/16 expressed a preference to remain in SG16. The reasons given were:
Q.3 has resided in SG16 over the last two Study Periods. Over this time it has been one of the most productive Questions in the ITU-T. Given its productivity it is unclear how a move to another Study Group could be justified on productivity grounds. The principle applied here if its not broken dont fix it.
H.248 is used by many different bodies who tailor its use through H.248 profiles to meet their application needs. ETSI Tispan, 3GPP, MSF and ITU-T SG11 all have defined profiles. Q3/16 itself does not define profiles thus the current structuring provides an efficient way to receive requirements from these bodies in order to update the H.248 sub-series.
Given the work load of Q3/16 it would not be appropriate to merge it with another question which would further increase time allocation problems.
Looking into future work it is seen that there are synergies with other questions in SG16. The IPTV work is a potential user of H.248 and work will be required on the interaction between RTSP and H.248. AMS has identified H.248 as a potential protocol for distributed components in AMS. There are synergies with the signal processing questions as there are H.248 sub-series Recommendations dealing with DCMEs, ECHO control etc. The work in Q11/16 relates also to gateway behaviour and H.248 is assumed to be a key part of this. The potential new question of Vehicle gateways may also benefit from the experience of the media gateway experts.
Conferencing and multimedia remain an integral part of the functionality of H.248. The experts of SG16 have an in depth knowledge on conferencing and multimedia implementations that allows for adhoc discussions at meetings which allows accelerated work. If Q3/16 was moved to another SG these adhoc discussions would then need to be formalised as liaisons which would add overhead and delay the work.
Risk of loss of expertise and increased cost of participation. The current Q3/16 experts also have an interest in other SG16 questions. If the question is moved to another SG then the delegates will face increased costs in having to attend both groups. In this situation the experts may have to prioritise other work and we will lose this expertise.
It was noted that in general the proposals for moving Q3/16 do not come from organisations representing the participants of the Question.
Q.3 Question Text in the next Study Period

It was agreed to accept the proposal from C.446 on 6.2.3 with the addition of text to describe the case of a descriptor audit and an error descriptor.
It was further agreed to start work on a new work item on the new package. The text provided in C.446 is the baseline for the work item. However it was agreed that the base publishing property text would be removed in favour of an editors note indicating that the property may be better at a package level to allow different publishing behaviour. An editors note would also be added to the procedures section to indicate that they have to be updated pending the resolution of the editors note on the base publishing property.

It was decided to keep clause IV.1.1.2 Relation to H.248.47 as the figure shows H.248.47.
It was agreed to add some text indicating whether the examples assume support of both the base and extended PackageIDs.
In response to the IV.2 Contributors note the following H.248.1 text was noted: 7.1.15 Statistics descriptor states: The Statistics Descriptor provides information describing the status and usage of a termination during its existence (ephemeral) or while it is outside the NULL context (physical).
It was agreed to remove important use-case from the relevant headings.
It was agreed to add some text to IV.3.3 to indicate that a subtract will also deactivate statistics.
The title of clause IV.3.4 should be changed in order to distinguish the example from clause IV.2.3.
IV.6.3.1 It was agreed to update the proposal to indicate whilst the use of ADD is possible it would most likely result in the return of statistics set to their initial value.
The output draft H.248.1v3 Appendix IV can be found in TD 580/WP2 R1.
It was noted that clause IV.5.7 Read and Reset Statistics without Disabling may need to be re-incorporated via Contribution at a subsequent meeting.

The delegates agreed this may be interesting for future work. On option 2 it was suggested that a statistic could be defined and that H.248.47 could be used to report when overload occurs. There were some concerns on the stand alone usage of that option 2. It may be better to use this in conjunction with option 1. With respect to Option 1 it was seen that there were multiple ways to enable this behaviour. As there was no proposal there is no impact to the current Amendment.

H.248.14 Inactivity timer package
HYPERLINK "http://www.itu.int/md/meetingdoc.asp?lang=en&parent=T05-SG16-C-0370" C.370 New event parameter in it package of H.248.14 to enhance reliabilityZTE This Contribution was discussed. It was highlighted that H.248.1 section 8 states Applications should implement an application level timer per transaction. Expiration of the timer should cause a retransmission of the request. It was thought that the proposed new property duplicates this behaviour. In discussion of previous Contributions related to this topic it was agreed that the timer value could be modified as necessary. The proposal was not agreed. Further Contribution may wish to describe the linkage of H.248.14 to H.248.1 section 8 with regards to retransmission.

There was some concern that according to T.120 that the MCU would not be aware that a white board application is running thus it would not be possible for a MGC to set this indication on an MG. Thus it was questioned if the proposal met the current procedures of T.120. Furthermore it was noted that there currently has been no work on decomposing T.120 to fit with a MGC and MG.
The proposal was not accepted. It was recommended that further Contribution on a T.120 based white boarding solution should examine figure 3 in T.120 and analyse how each part of T.120 adapts to the H.248 model.

It was unclear for the delegates how the DSP property actually mapped to physical resources. It was also noted that H.248.resman already contains the ability to reserve certain types of resources and that this proposal would cause duplication.
The proposal was not accepted.
No output draft generated as there were no changes to the input.
It was noted that 3GPP CT3/CT4 are working on requirements for floor control. It is expected that Q.3 will receive these requirements at it next interim meeting. There is a timing dependency between the freezing of 3GPP Release 8 (December 2008) and the scheduled Consent of H.248.19 (January 2009).

Clause 6.6.3.3 and 6.6.3.4 is wasnt clear that the maximum or minimum event was only reported once. The text needs to be changes to the effect:
If the current value is greater than the previous value and the Maximum, and if the event has not already been reported then the Event with the current value of the statistic shall be reported.
General: It was felt the Resumption property should be renamed to the Compliance.

Clause 6.2.1.1.7: add note to indicate relation to H.248.59.
Clause 6.2.1.1.8: Add a Note that the max min values do not relate to properties.

There were some concerns that Appendix III may give implementers the wrong idea that Context Priority is used for bearer level QoS. It was decide to remove the Appendix III text and replace it with the following:
The H.248 context attribute priority (see clause 6.1.1 of [ITU-T H.248.1) may not be re-used as codepoint for QoS class signalling, and it therefore does not replace the functionality of the QoS class package.
H.248.52 was revised (TD 543/WP2 R1) at the meeting. This revision was reviewed and it was agreed to put forward the Recommendation for Consent.
There were some concerns that the iqo and tm properties were set at a local and remote level and not able to be set on LocalControl. A compromise of supporting both local control and local and remote was offerred how it was decided to keep local and remote only at this stage. The reasoning being that the functionality of local control could be emulated by setting on local and remote. If both local control and local/remote was allowed then the relation of local control and its effect on local and remote would need to be described.

Clause 6.1.1 as per the Contribution should be moved to the scope section.
Clause 6.1.1 text should be modified as follows:
This Recommendation deals with functions (1) and (3) only. Other functions are out of the scope of this Recommendation.
In addition, the recommendation assumes that regarding (7), RTP and RTCP flows are always mapped into a single H.248 stream. Other mapping schemes are out of the scope of this recommendation and may make this Recommendations procedures irrelevant.
Clause 6.6.4 is to remain as per the base line.

However it was agreed that the use of the SDP RTCP related attributes in the local Descriptor would not be limited by the Package. Furthermore it was agreed that the Recommendation would not prevent address and port being used in SDP RTCP related attributes. It was also agreed that the rtcph/rsb property controls whether or not a RTCP is allocated.
It was agreed for the editor to provide a text proposal to incorporate these understandings.

It was questioned if the information in the proposal would be relevant for the network statistics? It was clarified that Network statistics was later 4 and above.
The delegates thought that it the text would better focus on a packet to stream assignment function rather than a context to packet assignment function. It was thought these assignment procedures may also relate to other statistics packages.
The delegates were unsure whether gate management properties should be processed after a flow is matched to a stream. It was suggested to explicitly mention that we dont consider H.248.43 to be used for flow identification. Editor to indicate why H.248.43 is not used for flow identification.
The lookup structures were updated to take into considerations:

Clause 6: In cases where the steady state may be determined and the resources may be freed, used correctly the packages will have little detrimental effect on pooling or dimensioning and enhance resource availability for a particular connection. In other cases the use of the packages needs to be considered against potential pooling or dimensioning issues as it may lead to an increase in the utilisation of the resources.
Clause 6 Editors note to be added Procedures could be added to discuss how to clear the resources.
Clause 8.1.1 It was agreed to keep the ABNF. It was agreed that the ASN.1 wasnt that helpful due to compiler issues. It could be imagined that a new parameter could be added to the base protocol to indicate a reservation.

HYPERLINK "http://www.itu.int/md/meetingdoc.asp?lang=en&parent=T05-SG16-C-0395" C.395Draft H.Sup7 Update of clause 8.4 Case (d): Disconnected H.248 Control Association renewal requestAlcatel-Lucent This Contribution was discussed and the proposal was accepted.
Clause 8.4 step d3 - is the issue. The Ericsson interpretation is that a Disconnect should be re-issued according to their interpretation of 7.2.8.1.11 The Media Gateway Controller may return a ServiceChangeMgcID parameter that describes the Media Gateway Controller that should preferably be contacted for further service by the Media Gateway. In this case, the Media Gateway shall reissue the ServiceChange Command to the new Media Gateway Controller.
However other delegates felt that it was not possible to re-issue a Disconnect to a separate MGC because it would constitute a new control association. i.e.7.2.8.1.1 Disconnected: always applied with the Root TerminationID, indicates that the MG lost communication with the MGC, but it was subsequently restored to the same MGC (possibly after trying other MGCs on a pre-provisioned list). Since MG state may have changed, the MGC may wish to use the Audit command to resynchronize its state with the MGs.
Given this majority understanding it was agreed to move forward with the case proposed.

HYPERLINK "http://www.itu.int/md/meetingdoc.asp?lang=en&parent=T05-SG16-C-0373" C.373H.248.MSRP - New proposed Package for Message Session Relay Protocol Support ZTEThis Contribution was discussed in conjunction with a liaison on the issue (TD 526/GEN). The delegates indicated that they couldnt see any requirements specified in the ITU work. The Contributors replied that there is work ongoing in SG11 in Q.conf and ETSI Tispan in TS 183 005. The delegates also thought that for the MSRP session mode most of control can be done through SDP however for decomposed architecture there may be extra requirements due to the SIMPLE working group. It was agreed that the proposal doesnt provide sufficient background on requirements especially for breaking down into chunks. The proposal was not agreed. It was agreed to investigate a work item on H.248 MSRP support. Contributions are solicited on requirements/architecture in order to develop baseline text.

H.460.natdet
TD 590/WP2 Network Address Translator and Firewall Device Determination [Rapporteur]
It was noted that terms like cone NAT need to be defined. There are definitions in the IETF and we have a technical paper published in the ITU that define these, but we need a normative reference and/or a definition within this document. It was agreed to assign the number H.460.23 to this draft Recommendation with intent to consent at the next meeting.
H.460.p2pnat
TD 591/WP2 Point to Point Media through Network Address Translators [Rapporteur]
We need to look at the updated work the IETF is doing related to STUN and perhaps reference the newer document if it is published before we put this text forward for consent. We should also make sure that all terms are properly defined or referenced. It was agreed to assign the number H.460.24 to this draft Recommendation with intent to consent at the next meeting.
H.proxy
C.483 Updated draft for new H.Proxy "Proxy-aided NAT/FW Traversal Scheme for H. 323 Multimedia Systems" [MII, ZTE]
It was suggested to change the last sentence in the scope section to read Proxy-aided NAT/FW traversal Scheme highlights potential issues with deploying those H.323 NAT/FW traversal solutions and describes how those solutions are applied in such cases. A revised document was published as TD 622/WP2, though it was noted that the scope section was not modified as intended. With further editorial refinement, it was agreed to put this document forward for approval at this meeting as an H-series supplement. The output document appeared as TD 496/Plen.

Incoming Liaison Statements
TD 490/Gen LS on a three-party query response IdM model [JCA-IdM Co-convenors]
It was agreed to send a liaison to IdM. The text of the liaison was reviewed during the Working Party 2 meeting and included in the Working Party 2 report.
TD 492/Gen LS on work plan for trusted service provider identity (SPID) Recommendations [Rapporteur Q6/17]
Noted.
TD 496/Gen LS on draft new Recommendation G.hnta - Generic Home Network Transport Architecture [SG15]
There was a question regarding how QoS might be controlled via this architecture. There was also a question related to how equipment in the home network might interact with a mobile device. The latter is of particular interest to Q12, since an AMS terminal might reside in a mobile device, but might utilize application that sit within the home network and communicate over the broadband connections within the home network. It was suggested that we send a liaison to highlight what we are doing in Q12 and the desire to ensure that mobile aspects are considered within the home network architecture. There was also a question raised regarding how NAT/FW traversal issues might be addressed and where the functions might reside in this architecture. We anticipate from the multimedia perspective that there will be data-generating equipment residing inside the home and transmitting out into the public network. The liaison appeared as TD 609/WP2.
In review of the liaison, a question was raised as to what actionable item we can give them. Perhaps we should request that they consider how AMS might be utilized within the home network and consider AMS as part of their future work plans? It was noted that SG15 experts may not have another meeting until after the WTSA meeting. With additions per the discussion, it was agreed to send this liaison. It appeared as TD 609R1/WP2.
TD 524/Gen LS on countering spam by technical means [SG17]
Refer to the Q25 meeting report.
AMS Requirements
TD 561/WP2 Summary of AMS Requirements [Editor]
It was suggested that we need a new section added related to accessibility. It was noted that the introduction of the document says that were in the requirements gathering phase, but in fact were now into the architectural specification phase. New requirements are certainly welcome, but perhaps the wording of the introduction should be changed to reflect the current status. This document was updated based on discussion and input contributions and the final text appeared in TD 561R1/WP2.
In review of TD 561R1/WP2, it was noted that the text in section 1 still says that the project is in the requirements gathering phase, but we have moved to an architecture specification phase and the text should reflect that fact. A typo exists in requirement MOBT-101 (quotation mark). It was suggested removing the text and will receive an appropriate indication of the handoff at the far end from the end of the second MOBA-100 requirement. It was noted that there are two requirements with the number MOBA-100, so the second should be renumbered.
The final output of the requirements document appeared in TD 561R2/WP2.
C.325 Proposed AMS Requirements [Dilithium]
It was agreed that the word provide should be enable in SEC-100, since we do not intend to mandate use of security. We had a discussion on application mobility versus terminal mobility. We want all applications to work when terminal mobility occurs, but we do not want introduce too much complexity. It was agreed that we would split the mobility requirements into two sub-sections: application mobility and terminal mobility. The wording of the second proposed mobility requirement seemed a bit confusing, as it was not clear whether it was intended that the AMS terminal have 2G functionality or whether this was strictly a gateway requirement. There was also a desire expressed to notify the user as to why a change occurred (e.g., why video stopped working). The contributor agreed to work with the editor to insert the requirements with clarified wording.
C.326 AMS Requirement Situation Discussion [Dilithium]
We captured some of the comments raised in this contribution above in the review of TD 561/WP2.
C.434 Mobility Requirements for AMS [Korea]
The points raised in this document are valid, but one issue we must be mindful of is the fact that the AMS terminal might transition from one type of network to another (e.g., WiFi to WiMAX), but the micro applications might not transition. For example, if one is receiving a video stream on a video display that has its own network connection, one would not want terminal mobility to negatively impact the video stream on the video display. The requirements were agreed to be added to the requirements summary with the necessary changes regarding applicability to what entity would be informed/affected.
AMS Project Description
TD 562/WP2 AMS Project Description [Editor]
Reviewed.
AMS Catalogue
TD 566/WP2 AMS Catalogue (Applications/services, scenarios and devices) [Editor]
We had a discussion in relation to this document to solicit scenarios on accessibility to help influence our requirements and work. Q26 can provide input on the scenarios. It was decided to send a liaison with this document attached to provide information to Q3/2 and get input with respect to human factors. The liaison appeared as TD 648/WP2.
AMS Terminal Architecture
C.316 Proposed skeletal document for AMS Architecture [UNC]
There were a number of questions regarding leveraging existing technologies, orchestrating communication between various micro applications, etc. It was concluded that we still have a lot of work to do, but this document provided a good framework for progressing that work. It was suggested that, since this document focuses strictly on the terminal side of AMS, we should change the scope of the document and diagram to reflect that it is a terminal architecture. It was agreed to accept this as the baseline text for the terminal architecture of AMS. In Figure 1 we should add below the AMS network a connection to the NGN network and other packet switched networks. It was proposed to either remove the other protocols (H.323, SIP, XMPP) or move them such that their usage is less confusing as they are currently presented.
Contributions are solicited to help flesh out each of the sections of the architecture document.
Miscellaneous
C.318 Liaison with OASIS [UNC]
There was a brief discussion to understand the scope of the communication and the apparent concentration by OASIS on web services (as opposed to SOA). It was agreed to draft a liaison to OASIS as proposed. The liaison appeared in TD 624/WP2. There were a few minor editorial changes made and agreement was reached to send this to OASIS. The final text of the liaison appeared in TD 624R1/WP2.
C.331 Consideration Issues for the Networked Robots as an AMS terminal [ETRI]
It was suggested that we ensure that the AMS Catalogue records some of the networked robot scenarios to help us ensure that we design the system to enable these kinds of capabilities. Experts asked for more information on CAMUS and the desire to use a transport protocol other than TCP.
Intellectual Property Statements
No IPR statements were received at this meeting.
Outgoing Liaison statements
The meeting agreed to send four liaison statements. One was in response to TD 496/Gen on home networking. Another liaison was sent as proposed in C.318 to OASIS. The third liaison was sent to ITU-T SG2 ITU-T SG2 to solicit input from the human factors perspective on the AMS Catalogue. The final liaison statement was sent to the JCA-IdM to solicit input and collaboration on identity management issues as they might relate to AMS.

These incoming Liaison Statements were reviewed and discussed during the Rapporteur meetings. The followings are the discussion and the results.
TD 492 (GEN/16) LS on work plan for trusted service provider identity (SPID) Recommendations from Rapporteur Q6/17 reports on a work plan for accelerated development of a set of Trusted Service Provider Identity (SPID) related Recommendations. Four Recommendations will be drafted for accelerated development and approval as part of the SG 17 work plan. It is important to assess this work because it might have a big impact on the actual implementation of IPTV services.
Collaboration and harmonization with the currently widely used identifiers will also have to be carefully evaluated.
TD 496 (GEN/16) LS on draft new Recommendation G.hnta - Generic Home Network Transport Architecture from ITU-T SG 15 reports that Study Group 15 produced the attached draft new Recommendation G.hnta - Generic Home Network Transport Architecture. We took note and will try to harmonize with their work.
TD 502 (GEN/16) LS on information of SG 5 activity related to Home Networking and IPTV from ITU-T SG 5 informs us that they made progress at their Study Group 5 meeting in Geneva, 25 29 February 2008 and their draft Recommendation K.hnw, EMC, Resistibility and Safety requirements for Home network devices was consented and is now proceeding to AAP as draft Recommendation K.74. We take note, and will review their requirements.
TD 504 (GEN/16) LS from IETF MMUSIC WG on ongoing work on RTSP 2.0 and request for information on RTSP extensions from ITU-T SG 16 Chairman (on behalf of IETF) informs us of the on-going work on version 2.0 of the Real Time Streaming Protocol (RTSP) in the IETF MMUSIC working group. It emphasizes that any development of protocol extensions and mechanisms related to RTSP would need to occur under the guidelines of RFC 4775. And it is also asking us to let them know if any of us is working on technical specifications that make use of RTSP and if any protocol extensions are being considered. [We can reply that ITU-T Q13/16 is working on specs of IPTV, and RTSP is one of the candidate protocols of IPTV, especially for VoD. But currently Q13/16 is not considering any extension to RTSP. We currently have no requirement for RTSP to be extended.]
TD 511 (GEN/16) LS on progress of J.stb-spec Component Definition and Interface Specification for Next Generation Set-Top Box from ITU-T SG 9 Joint Rapporteurs Qs 5 and 9/9 informs us of their progress on draft new Recommendation J.stb-spec, which is applicable to enhanced broadcast services over any type of access media. The draft document is planned to consent this at the next SG 9 plenary meeting, 5 - 9 May 2008, in Geneva. (More to be reviewed in detail) Take note and reply an LS.
TD 522 (GEN/16) Reply LS on call for comments on draft new Rec. H.iptv-hn (COM 16 LS 269) from ITU-T SG 17 informs us of their activities relevant to IPTV Home Network Security.
TD 524 (GEN/16) LS on countering spam by technical means from ITU-T SG 17 informs of their newly drafted two draft Recommendations on countering Spam during the April 2008 meeting:
draft ITU-T Recommendation X.fcsip, Technical framework of countering IP multimedia spam
draft ITU-T Recommendation X.ssf, SMS filtering system based on users rules
and asks for our comments. We need to review this more in detail, in the meantime, we take note.

IPTV-GSI-C78 Proposal of audience measurement API for IPTV middleware Document TD34, OKI
These contributions were reviewed and discussed during the Rapporteur meetings. The followings are the discussion and the results.
COM16-C368 is valid to IPTV. But the service component can be optional in the web-based case. And the figure should reflect this fact and an explanatory text should be given. With those modifications, the contribution will be included in H.IPTV-MAP, as a new clause on Web-based IPTV terminal middleware.
COM16-C426 states that there is now a clear overlap between Question 13/16 and Question 4/9 on Application Programme Interfaces. Q13/16 believes there is no overlap. To this contention, Q13/16 will provide a TD describing the technical aspects of Q13/16 activities, making reference to the LS produced at the Q13/16 Rapporteurs meeting at Malta (this was published subsequently to the meeting as HYPERLINK "http://www.itu.int/md/T05-SG16-080905-TD-WP2-0679/en" TD 679/WP2).
COM16-C432 from Republic of Korea proposes to update the existing text in the Application event section in H.iptv-map so that it has more accuracy and precise scope. It also proposes to make an independent document for Application Event because its characteristics and aspects are different from those of other parts on H.iptv-map. It is generally agreed that such a document is necessary, as part of the Recommendation series. H.IPTV-AEH has been created.
COM16-C456 describes some points of standardization, which includes not only FEC but also retransmission and the combination of both. It also gives examples and explanations of ALER. It also gives some general architectural consideration involving ALER. It does not specifically propose technical solutions. It may supplement the current FG-IPTV deliverable on ALER and may be included in that document. This was discussed with Q23 during the joint meetings. See the details of the discussion at the Joint meeting section.
IPTV-GSI-C11 from Sumitomo Electric proposes to assign a draft Recommendation name on the document Application layer error recovery mechanisms for IPTV services to start and accelerate the remaining work items towards consent for a new ITU-T Recommendation. It is agreed that it might be a feasible idea to give it a name such as H.IPTV-ALER to attract more contributions and to accelerate the work on this document. This was further discussed with Q23/16 during the joint meetings. See the details of the discussion at the Joint meeting section.
IPTV-GSI-C52: Which existing IPTV technical specifications that are already defined in each region or country does this contribution refer to? Are there any specifications that are already defined in each region or country?
J.290 and J.292 are not always consistent with each other. (e.g. Table1 in J.290 and Table 1 in J.292 have the same title Baseline and extended SVD functionalities but they contain different information. )
They refer to documents that are not publicly available or still under development. It is not consistent with many currently available IPTV systems. (e.g. UPnP remote UI is mentioned in the text, but it is not a standard.)
It is proposed that every IPTV regional specification that has been already established or currently under development should comprehensively be supported, but this is impossible.
IPTV-GSI-C53 states about telephony. Although IPTV should support telephony, it should not replace telephony. These APIs are already defined elsewhere. It is not broadcast-centric. APIs should be open enough to allow these services, but they need not be specified. Q13/16 thinks this contribution is not appropriate for inclusion in the document.
IPTV-GSI-C54: The figures have been modified already to differentiate the functional and physical aspects of IPTV terminal architecture.
IPTV-GSI-C56: This is more relevant to terminal device rather than middleware. It is clearly CDN oriented, and not broadcast centric. The flows show clearly non-broadcast centric scenarios. To be included in the terminal device doc.
IPTV-GSI-C78: Metadata document already has audience measurement metadata. Middleware only needs to have APIs for handling metadata. This can be an optional feature of metadata API. Otherwise, we would have to define APIs for each different application.
Temporary documents
TD 606 Draft proposal for the document structure of IPTV Related Recommendations, Rapporteur Q13/16
TD 607(WP 2/16) Discussion materials for H.iptv-map, Rapporteur Q13/16
These temporary documents were reviewed and discussed during the Rapporteur meetings. The followings are the discussion and the results.
TD 606: The proposed structure was agreed in principle. According to the plan, the following four new draft Recommendations were drafted.
IPTV Service Discovery and Acquisition [H.IPTV-SDC created from H.IPTV-MAP]
Distributed Service Middleware [H.IPTV-DSMW created from H.IPTV-MAP]
IPTV Application Events Handling [H.IPTV-AEH]
IPTV Metadata [H.IPTV-MD]
TD 607: It is necessary to clarify the meanings of Ë%, ---, and an empty box int the table. E.g. in Name Identification (deprecated). At least to add a note explaining. E.g. to say, Ë% means supported, or --- means not supported , etc. What is the goal of this table? We need introductions for CE-HTML, Mini-HTML, etc. Before profiles, HTML itself has to be introduced and which version it is, etc. The table is more appropriate in the appendix, because the body of the Recommendation can just refer to the existing specifications, such as defined in CEA-2014. The title of the column Element should be named HTML 4.0 Elements To make it clearer, a reference to W3C HTML 4.0 should be made. In this table, the distinction between element and attribute is not clear. It should be clarified. We need more contributions for the rationale or the justification of this Mini-HTML. W3C has already defined a subset of HTML, e.g., Compact HTML for small information devices. More contributions are called for NCL (Nested Context Language).
This material gives more information concerning NCL and LUA. It is to complement the current subclause 6.11 of the Annex A of H.iptv-map. Q13/16 notices that subclause 6.9 of the Annex A of H.iptv-map is also relevant to this material and is supplanted by it. Q13/16 considers that the current subclause 6.9 of the Annex A of H.iptv-map can be deleted and subclause 6.11 of the Annex A of H.iptv-map can be updated with the material contained in this TD. Since this Annex is derived from an FG IPTV deliverable, Q13/16 proposes this to IPTV-GSI.
Joint Activities
Joint Meeting on Codecs
Questions 6, 13 and 23 of Study Group 16 met under the joint chairmanship of Mr Gary Sullivan (Rapporteur for Q.6), Mr Thomas Wiegand (Associate Rapporteur for Q.6), Mr Masahito Kawamori (Rapporteur for Q.13) and Mr Hervé Taddei (Rapporteur for Q.23).
The meeting discussed the IPTV Toolbox for Content Coding document that was produced by the IPTV Focus Group ( HYPERLINK "http://www.itu.int/md/T05-SG16-080422-TD-GEN-0528/en" TD528/GEN) which has been allocated to Study Group 16 for further consideration. The document was noted to not be a Recommendation or specification of codec technology requirements or signal protocols for IPTV, but rather a collection of some information about various example codec technology that exists in the market and may or may not actually be appropriate for specification in an ITU-T Recommendation. It was remarked by some participants that the current content of the document could need correction of some information, updating, references to additional material, etc.
It was agreed that the responsibility for future evolution of the section of this document on video coding will be allocated to Q.6/16 (Visual Coding) and that the responsibility for the remainder of the document, including the speech and audio coding parts, will be allocated to Q.23/16 (Media Coding) in consultation with Q.10/16 (Extension of existing voice coding standards). It is anticipated that these Questions will continue into the next Study period with broadly similar remits. Q.6/16 and Q.23/16 will also co-ordinate with Q.13/16.
Q.6/16 and Q.23/16 are requested to review the current text of the IPTV Toolbox for Content Coding with respect to accuracy and completeness, and also in the context of the IPTV Service Requirements document produced by the IPTV Focus Group (now allocated to Q.2/13, see HYPERLINK "http://www.itu.int/md/T05-IPTV.GSI-080115-TD-GEN-0040/en" TD 40/IPTV-GSI). Mr Kawamori kindly agreed to publish that requirements document as a SG16 Temporary Document.
It is anticipated that this work will take place via correspondence and at interim meetings. Once the Toolbox document has been reviewed and updated by Q.6/16 and Q.23/16, SG16 must determine how to proceed: options include publishing the updated document as an informative document such as a Supplement; using it as the basis for a future Recommendation perhaps similar to the DVB-H specification in ETSI TS 102 005; or both. It is envisaged that this decision will be taken at the next Study Group 16 meeting, or possibly sooner via GSI co-ordination, depending on progress. It was also observed that SG16 must decide whether it needs to address aspects such as media transport in the future of this work.
The WP3/16 Co-Chair (Mr Paul Barrett) commented that he would also seek input from Q.26/16 on how to address the accessibility aspects of the Toolbox document.
Note: during the meeting there was a discussion regarding the best way to handle the joint ownership of the Toolbox document by Q.6/16 and Q.23/16, and there was a suggestion to divide the document into separate parts. As a result of subsequent discussions in Q.26/16, it is proposed that the document remain as a single document and Q.6/16 and Q.23/16 co-ordinate to maintain their respective sections. Both Q.6/16 and Q.23/16 are requested to include the accessibility considerations in Appendix II of the Toolbox document in their review work.
Joint Meeting on Error Recovery
Questions 6, 13 and 23 of Study Group 16 met under the joint chairmanship of Mr Masahito Kawamori (Rapporteur for Q.13) and Mr Hervé Taddei (Rapporteur for Q.23) for discussing IPTV Application Layer Error Recovery document from FG IPTV.
Q13 will have the responsibility for the document (IPTV-FG). Q23 will support the work of Q13. But the work item itself belongs to Q13.
TD-07(application layer error recovery) produced in Seoul and C11 are documents of IPTV-GSI.
Strictly speaking, the GSI meeting is a different meeting from SG16.
An issue was raised concerning the handling of the documents submitted to IPTV-GSI, and their relationship to the discussion within SG16.
Contribution GSI-C11 is in fact a contribution to IPTV GSI, and officially it is supposed to be discussed during the GSI meeting. So this document is reviewed as information, but a decision on the proposal will be made during the GSI meeting.
SG16-C-456 by Huawei
Is ALER the same as AL-FEC? ALER is a generic term, encompassing AL-FEC,etc. Why do we need to regulate this? Regulating means standardizing. Generalizing error recovery mechanism is a better approach.
What is its relation with measurement report? This needs to be clarified, especially within the context of NGN. FG-IPTV document on Traffic management has information on this.
This document can constitute the text of Clause 9 Quality of Application Layer User Experience of the draft Recommendation H.IPTV-MAP.
There was a proposal to look at the requirements for such mechanisms more closely within Study Group Questions. An issue was raised about the concern about IPR.
Liasons with other SDOs will be considered at the next meeting.
Joint Meeting with MPEG
On 27 April, 2008, ITU-T Q13/16 held a joint meeting with ISO SC29/WG11 (MPEG) at ITU, Geneva. Mr.Masahito Kawamori (NTT, Japan) and Mr. Xin Wang (ContentGuard, USA) chaired the meeting.

Joint Meeting with MHEG
On 28 April, 2008, ITU-T Q13/16 held a discussion on T.172 and ISO/IEC JTC 1/SC 29/Maintenance Task Force on ISO/IEC 13522 Series. Mr.Masahito Kawamori (NTT,Japan) chaired the meeting. This is the meeting report of that meeting. See TD/16 for the detailed results.
ISO/IEC JTC 1/SC 29/Maintenance Task Force on ISO/IEC 13522 Series is pleased to join the maintenance work in Q13/16. They suggest that ITU-T also adopts ISO/IEC 13522-5 (1997) Technical Corrigendum 1 (1999) for its twin text counterpart T.172 (02/1998). The maintenance work would be facilitated if some help from the current implementers in the UK, specifically some suggestions for possible enhancement and revision of the standard beyond the corrigendum. ISO SC29 will contact them for help.
Workplan for the maintenance of T.172 (ISO/IEC 13522 Series).
- Corrigendum
- Joint work with ISO/IEC JTC 1/SC 29 on the enhancements of T.172 (ISO/IEC 13522 Series) for IPTV
Q13/16 thanks ISO/IEC JTC 1/SC 29 for the reply LS and the information on Corrigendum, also for offering its help in maintenance and updating of T.172 (ISO/IEC 13522 Series). Since Q13/16 is tasked with recommending specifications for Multimedia application platforms for IPTV, we would like to invite ISO/IEC JTC 1/SC 29 to work jointly on the enhancements of T.172 (ISO/IEC 13522 Series) for IPTV.
It is envisaged that Q13/16 will meet in conjunction with IPTV GSI events, and we propose to have joint meetings, if possible, to discuss those issues relevant to the enhancements of T.172 (ISO/IEC 13522 Series) for IPTV. But the work item itself belongs to Q13.

Discussions
Incoming Liaison Statements
TD504/GEN informs us the on-gong work on RTSP 2.0 in IETF MMUSIC. RTSP is widely accpected as a session control protocol for, for example VoD service. With respect to the working area of Q.21, H.610 uses the current version of RTSP for VoD session control. In the meantime, the LS also asks information on extensions of RTSP taken placed in other bodies. Q.21 confirmed that these is not technical extension or modification taken placed at Q.21 and that Q.21 mainly uses RTSP as defined in IETF. As a result of the discussion, Q.21 agreed to send a reply liaison statement with information of H.610 and to ask to keep us updated on the future development of RTSP. The reply LS may be combined with the text produced at other Questions.
TD497/GEN informs us the recent update of Access Network Transport (ANT) Standards Overview and Work Plan. In the era of broadband and NGN, it is important for the multimedia experts to know the performance and technnical characteristics of Access Network because the Access Network sometimes becomes the bottleneck of multimedia application demanding a more bandwidth than conventional application. From this view point, the current form of ANT Standards Overview can be improved to be more friendly to the multimedia experts, for example putting a short summary or a compact table containing key features of each Access Network technology in this document. The imporved ANT Standards Overview will be more frequently utilized among the multimedia experts and may be referred in the future made docuemnt as an important reference. Also, it was pointed out that H.ghna needs to be included in ANT Standards Overview. Q.21 agreed to send a reply liaison statement incorporating these views to SG16 and to ask further collaboration.
TD500/GEN informs us OUI assignment to ITU-T. This OUI can be used to, for example, Protocol Identifier defined in ITU-T Recommendation. ITU-T SG15 acts as register within ITU-T. Currently, Q.21 has no work item requiring address assignement based on this OUI.
TD524/GEN informs us the development of two new draft Recommendations, X.fcsip and X.ssf, on multimedia spam in ITU-T SG17. In these draft Recommendations, some counter spam measures such as using sender information, communication contents and communcation features are mentioned. Countering spam will be an important consideration of future multimedia systems and will be considered in the future work if necessary.
TD501/GEN contains Questions for the next study period in ITU-SG15. Among Questions in SG15, Q.1, 2 and 4/15 are spcifically related to Q.21 activities. The activities in these Questions are complementary to Q.21 and no overlap is observed in this discussion. Also, it was pointed out that the collaborationw with these Questions is productive and shold be continued in the next study period.
TD522/GEN, which is inputted from ITU-T GS17 and includes their comments on H.iptv-hn, is discussed in IPTV-GSI.
Home Network
TD540/WP2: This TD contains the updated draft of H.ghna produced at the interim meeting held in January 2008. This document was reviewed with C329.
C329: This contribution contains the proposed text modification of H.ghna. Summary, keywords and introduction that were empty in TD540/WP2 were added. Figure 6.2 that presents transmission aspect of home network architecture is updated, and aligned with G.hnta, which is another Home Network architecture draft recommendation, currently being developed at ITU-T SG15 (see TD499/GEN).
The concept of Primary and Secondary domains/terminals is an essential idea of H.ghna. The explanation of this idea is added in clause 6.3.
Clause 8 of H.ghna describes management mechanism for home network and devices within it. The current text only describes existence of technical solution available in the market, because the use of these solutions needs further study. Also, the explanation of IP address management with some new figures is added in H.ghna.
TD512/GEN: This LS comes from SG9 and requests to make a reference to J.190 in the scope section of H.ghna. The meeting accepted this proposal. Also, the relationship between J.190 and H.ghna was discussed. The meeting agreed that H.ghna has the new concept of Primary and Secondary domains/terminals in its Home Network architecture and that both documents are complementary.
TD499/GEN: This LS provides comments and proposal of Q.1/15 on Home Network architecture. The transmission model of Home Network is discussed and aligned with G. hnta.
TD496/GEN: This LS informs the recent update of G.hnta discussed at ITU-T SG15. The meeting reviewed it and confirmed that H.ghna and G.hnta are well aligned.
TD495/GEN: This LS is mainly sent to ATIS IIF and also copied to SG16 for our consideration. ATIS IIF requested the clarification of proprietary home network. In response to this request, SG15 decided to use non-IP instead of proprietary. Also, SG15 requested the clarification of U-IF, which is defined within NT.
TD502/GEN: This LS informs the consent of new Recommendation K.74 (hnw) on EMC impact on Home Network transmission. Also, this LS contains interesting information about EMC problem happening when home network is used with problematic consumer electric device. The meeting concluded that this issue is important in the consideration of quality aspect of Home Network.
C330: This contribution tries to initiate a new study on Home Network QoS. Q.24 will take care of this issue.
TD498/GEN: This LS informs that SG15 has started a new study on Home Network QoS. SG15s work focuses on transmission aspects rather than service aspect. The meeting concluded that this work is also complementary to our work.
Regarding references, A.5 justification was produced and published as TD463/PLEN.
Networked ID
Networked ID was discussed jointly with Q.22/16.
See Report of Q.22/16 for details.
Visual Surveillance
Visual Surveillance was discussed jointly with Q.22/16.
See Report of Q.22/16 for details.
IPTV related items
IPTV related item is discussed as a part of IPTV-GSI. Currently, draft new Recommendation H.iptv-hn is being discussed.
Remote Management for Multimedia
TD488/GEN, an incoming liaison statement from ATIS IIF, was presented and discussed. The remote management is being discussed in several SDOs, and the use of DSL-F TR-069 based mechanism is the trend of the industry. H.iptv-hn, another Home Network draft Recommendation in the context of IPTV services, includes some descriptions of TR-069 based remote management. However, during the discussion, the possibility that the current data model defined in DSL-F may not cover all the possible use cases of multimedia services was pointed out. This means that current data models defined for some use cases such STB and gateway device need to be carefully examined and that additional objects may be added based on this analysis.
As a result of this discussion, Q.21 agreed to initiate a new study item on remote management, provisionally called H.RM-MM Remote Management for Multimedia Service. As the case of Home Network QoS study initiated in Q.24, this work item will start from the analysis of use cases as well as existing available solutions. Also, it was pointed out that this study may need to include the service selection and control because of its close proximity to the remote management.

Discussions
Incoming Liaison Statements
TD489/GEN LS on a proposed breakdown of the ITU-T Focus Group on IdM Use Case Gap Analysis (JCA-IdM Co-convenors)
In this breakdown listing, no particular items are labelled as assigned to SG16. However, as a result of our discussion, it was found out that from SG16 perspective, some security issues like federated security and single-sign-on mechanism may have relations with this proposed breakdown listing. A outgoing LS was drafted which is contained in TD 657/WP2.
TD490/GEN LS on a three-party query response IdM model (JCA-IdM Co-convenors)
We discussed this LS and found that for the time being, useful information may not be possible to be given in response from SG16 since we are currently not doing work directly related to IdM functional models. This point was made clear in an outgoing reply LS contained in TD 658/WP2.
TD505/GEN LS on NID Terms and Definition (JCA-NID Convener)
Based on our discussion, a LS was made to be sent to JCA-NID to inform them that SG16 would like to see that the two recommendations F.mid and H.mid will be able to provide them with some useful information and proper alignments can be kept between their ongoing work and these two recommendations. The outgoing LS appears in TD 659/WP2.
TD509/GEN Reply LS on proposal of a collaboration progress between ISO/IEC JTC 1/SC 6 and ITU-T SG 16 (COM 16-LS 271) (ISO/IEC JTC 1/SC 6)
We discussed this LS with the following conclusions:
[1]Since SG16 is not currently doing any work on USN middleware architecture though it may be one of our future work plan items, we dont think it is likely to develop any common text recommendation with ISO/IEC JTC1/SC6 for the time being as suggested by their LS. But it may be possible in the future at a proper time.
[2]SG16 is quite willing to keep in touch with ISO/IEC JTC1/SC6 to share information on USN and other related topics regularly.
A LS was composed based on the above understanding which appears in TD 664/WP2.
TD517/GEN LS on directory support for ID-based applications (ITU-T SG 17)
This LS and its attachment were reviewed jointly by Q21 and Q22. It was pointed out that directory may be a possible technical approach to ID resolution needed by ID-based applications, but it depends on practical implementation to choose the most suitable ID resolution mechanisms for ID-based applications. We drafted an outgoing LS to tell SG17 about our work on F.mid, H.mid, H.IDscheme and H.IRP which is to be found in TD 660/WP2.
TD519/GEN LS on ITU-T X.668 | ISO/IEC 9834-9 on an OID for ID-based applications and services (ITU-T SG 17)
Through discussion on this LS, it was found that an OID mechanism provided by X.668 may be useful for the purpose of supporting ID coding and ID resolution for tag-based ID triggered multimedia information access which SG16 have been working on. Our work in ID coding and ID resolution can work with various OID including those defined in X.668. OID making use of compact memory space is more suitable for our work. An outgoing LS was drafted as in TD 660/WP2.
TD523/GEN LS on USN Security (ITU-T SG 17)
Our work on USN, for the time being, hasnt brought us to rather deep thoughts on the security of USN in its every aspect. However, in this F.USN-MW, there are still some functional requirements that are relevant to security, for example, those in section 7.1.3. based on above thoughts, a LS was made to be sent back to SG17 which can be found in TD 661/WP2.
TD530/GEN LS
Q21 and Q22 jointly discussed this LS from SG13 which requests alignments between F.mid and Y.idserv-reqts. An audioconference was arranged with the help of Mr.Simao Campos to facilitate a joint discussion for SG13 experts to join. All alignement requests were appropriately handled. We reported back to SG13 all these processing outcome in an outgoing LS TD628/WP2.
Service awareness
C365: A Proposal on adding service awareness capability requirements for "Service Awareness and Traffic Control in Multimedia Communications" (China Telecom, Huawei)
This document proposes adding service awareness capability requirements to F.MSATC. After discussion, it was accepted. Questions were asked. For example, should content protection issues like DRM be taken in account? However, it is unclear at this stage how DRM can be handled by network devices supporting MSATC since DRM is supposed to be an E2E thing. Therefore, further study is needed.
C366: A Proposal to add policy requirements to "Service Awareness and Traffic Control in Multimedia Communications" (China Telecom, Huawei)
Discussion found that such requirements are reasonable so the contribution was accepted. It was pointed out by some experts how to define policies and the interface between the operator and the MSATC module will be a problem for study.
C367: A Proposal to add requirements for policy control and a statistic report capabilities to "Service Awareness and Traffic Control in Multimedia Communications" (China Telecom, Huawei)
Questions were asked. For example, what statistics are to be collected? can some examples be provided? Some experts pointed out that high-level languages for reporting statistics like TMN need to be considered. The requirements in this contributions partially overlap with those in C 459 so that is was agreed that these overlapping requirements in these two contributions are to be merged when taken into F.MSATC output. Also there are a couple of English problems which were highlighted and corrected when the text was incorporated into the initial draft of F.MSATC.
C441: Proposal for scenarios concerning differentiated service based on users in F.MSATC (MII China)
It was agreed that such requirements are necessary for F.MSATC. Questions were asked. One of the questions is if user terminal capabilities should be considered in the situation where such a knowledge will be useful to prevent a server from sending video streams to a user terminal supporting only voice. Experts thought it is a problem for further study in this area.
C442: Proposed resource management scenario in F.MSATC (MII China)
It was accepted into F.MSATC based on discussion. It was pointed out by experts that:
[1]Such service level resource management is needed mainly for those networks without a transport resource regulation mechanism like Internet.
[2]Resource considered here is bandwidth and other network side resource. Other resource like the processing power, ability to handle concurrent video streams of a server is not for consideration in the context of this contribution.
C443: Proposed security protection scenario in F.MSATC (MII China)
It was pointed out that for protection against DDOS attack, not only user terminal A is needed to be taken care of, but also those other user terminals captured by user terminal A to become its zombies to launch DDOS attack. The contribution was accepted into F.MSATC with this information being added.
C444: Proposed scenario for personalized service customization in F.MSATC (MII China)
It was accepted into F.MSATC. It was pointed out that the policies should be pushed by the management platform to the SATC entity as well as pulled by the SATC entity from the management platform. The original text mentions only transfer which is supposed to mean only push. One question of interest which is to be answered through further study is how advertising as a typical personalized service is to be supported. The expert who raised this issue also said that for F.MSATC those requirements oriented to practical commercial considerations should be encouraged in our subsequent study of F.MSATC.
C457: Proposed a skeleton for the new work item F.MSATC (Huawei)
It was discussed and accepted to serve as the structure of the initial draft of F.MSATC.
C458: Proposed overview chapter for draft new F.MSATC (Huawei)
It was discussed and accepted. Some English issues were corrected when merged into F.MSATC.
C459: Proposed the general requirements for multimedia service awareness and traffic control system in F.MSATC (Huawei)
Some questions were asked. For example, if service awareness on layer 7 in the OSI model is mandatory or optional, if the first requirement and the second one should be merged, if some examples are to be given for so-called mainstream P2P protocols, etc. All these questions were answered when this set of requirements were incorporated into F.MSATC. Also in requirement 11, it was advised by some experts to change the term periodic to automatic and change the term non-periodic to manual. TD 644/WP2 is the TD that contains this initial draft of F.MSATC.
Networked ID
F.mid and H.mid
TD564(WP2): Updated draft of new ITU-T Rec. F.MID "Service description and requirements for multimedia information access triggered by tag-based identification" (Editor F.MID)
TD565(WP2): Updated draft of new ITU-T Rec. H.MID "Tag-based ID triggered multimedia information access system architecture" (Editor of H.MID)
The above two TDs were reviewed by the meeting as the starting point to discuss work on F.mid and H.mid. Several editorial changes were proposed and accepted.
C376: Proposal on editorial enhancements of F.MID (NTT)
C377: Proposal on editorial enhancements of H.MID (NTT)
The above two contributions were examined and accepted. C377 proposes some changes to Fig.1 in H.mid, and during the meeting it is unsettled as to how to change the names of some entities in this figure. Experts including Mr.Kashizuka, Mr.Takashima, Mr.Kim, Mr.Tsukada had done offline work to reach an agreement. Those proposed changes are reflected in the latest versions of F.mid and H.mid to be found in TD564r2(WP2) and TD565r2(WP2) which are the documents for consent by this SG16 meeting. .
ID coding schemes
C420: Proposal of draft new Recommendation H. IDscheme on "ID schemes for multimedia information access triggered by tag-based identification" (ETRI and SCAT)
This is a piece of joint work by ETRI, Korea and SCAT, Japan in order to build some ID coding schemes for multimedia information access triggered by tag-based ID. The basic idea is to provide two ID coding schemes to be chosen depending on practical application context and implementation. The mainbody of the document provides only some basic framework thing, while there are two annexes containing two different ID coding schemes: xCode in Annex A and uCode in Annex B. Experts questioned if the OID mentioned in this document is consistent with X.668 and the answer is positive. It was found by the meeting such a structure is good for combining the work from different parties and give the potential implementor the flexibility of making choice. It was accepted and used to produce the initial draft to a new work item H.IDscheme. Mr.Koshizuka from Japan and Mr.Lee from Korea were appointed co-editors for this new work item. TD 673xxx/WP2 is the initial draft of H.IDscheme P for more study.
ID resolution protocols
C421: Proposal of draft new Recommendation H.IRP on "ID resolution protocols for multimedia information access triggered by tag-based identification" - Annex B (ETRI)
C422: Proposal of draft new Recommendation H.IRP on "ID resolution protocols for multimedia information access triggered by tag-based identification" - Annex B (SCAT)
The above two contributions provided two different ID resolution protocols for multimedia information access triggered by tag-based ID. Annex A is for the Korean method, and Annex B is for the Japanese method. They are both multi-stage methods which first (optionally) resolve OID and then resolve ID based on OID resolution result. They all can work with different OID systems including X.668. The Korean method makes use of existing technique such as DNS for ID resolution, in contrast, the Japanese method has its own ID resolution approach. It was pointed out by the rapporteur that if it is possible, a better acronym can be used to replace FFT meaning Fixed Form Type in the context since FFT has a much better known meaning for those working in communications and signal processing. They were accepted to be combined to build the initial draft for H.IRP, a new work item for which Mr.Koshizuka from Japan and Mr.Lee from Korea were appointed co-editors. TD 645/WP2 is the initial draft of H.IRP for more study.
Visual Surveillance
TD582(WP2): Updated draft of new ITU-T Rec. H.VSarch "Architectural requirements for visual surveillance" (Editor H.VSarch)
This document contains the latest version of H.VSarch.
C369: Proposed update on requirements and services description for visual surveillance (F.VSreqs) (ZTE, CATR)
This document provides an updated version for F.VSreqs and was accepted as a result of our discussion. Some questions were asked for clarification, like does storage mentioned mean both local and remote storage? Can we replace the term storage space with storage capacity? They were addressed with corresponding changes incorporated. The editor produced an updated output document for F.VSreqs as in TD643/WP2.
C378: Proposed Visual Surveillance Requirements for F.VSreqs (CATR, MII of P. R. China)
This document provides sections 5 and 8 for F.VSreqs for prose description of visual surveillance service and its convergence with other services. Some changes were proposed from the floor like some improvments to Fig.1 and were accepted. It was accepted with these proposed changes into an updated draft of F.VSreqs TD643/WP2.
USN middleware
C324: Initial draft Recommendation on service description and requirements for USN middleware (F.USN-MW) (ETRI)
This document provides an initial draft for F.usn-mw. It was discussed during one of Q21/16 and Q22/16 joint sessions. Several questions were recorded as follows:
[1]Shall we use the structure of some stable work like F.mid for this F.usn-mw?
[2]If there are some business names used in this document? If so, it may needs checking and usually such things require careful handling.
[3]What is the relation between USN node and RFID tags/readers in the second scenario called cold chain?
It was reported by the author that there isnt any business name in the document. The editor thinks it is good to borrow some good ideas from the structures of F.mid and F.741. The relation between USN nodes and RFID tags/readers is somehow complex, in this particular case of cold chain, USN nodes are just RFID tags.
It was accepted as the baseline for building the initial draft of F.usn-mw. The output can be found in TD 640/WP2.
C429: Proposal on light-weight realtime transport protocol for audio on USN (Korea (Republic of))
C430: Proposal on light-weight realtime transport protocol for video on USN (Korea (Republic of))
The above two contributions propose light-weight transport protocols for video and audio respectively to be used for data transmission from USN nodes to USN routers. It was found that this piece of work may have some relations with IETF RFC 3095 which defines a method for the transport of audio and video data in a light-weight manner through using header compression. The authors were told to carry out further study regarding this RFC 3095. Judging from other aspects, these two contributions are not mature enough either. Q21/16, Q22/16 would like to point out that for the time being, we are just doing work related to USN-middleware service descriptions and requirements, while architecture and protocols may be dealt with in the future. Therefore we need an architecture first to provide us with guidance as to what needs to be studied for audio and video transport. The conclusion is that further study is needed in the hope that the authors may be able to bring in more contributions in this area for our future meetings.
Home network
C329: Proposed text modifications for draft ITU-T Recommendation H.ghna (NTT)
C330: Initiation of a study for home network QoS in SG 16 (NTT)
About the above two contributions, please see Q21/16 report for discussion details.
Others
C 311: Proposed new appendix for F.700 on Multimedia Services Classification (Russian Federation Telecommunications Administration)
This contribution tries to introduce some new taxonomy principles for multimedia services by extending F.700 defined attributes. However, since the authors wasnt able to be present during the discussion, SG16 experts found many questions that couldnt be answered through the discussion. What is concluded by the meeting is that we d like to solicit further contributions and request the presence of the authors in person to facilitate future discussion.

New topics
(C 431) Adaptive end-to-end QoS control based on variable bit rate codec in wireless networks [Korea]
This contribution was presented. There was a question about how to obtain the path information for QoS control and it was answered that the path information can be collected in an end-to-end basis for optimal QoS control. It was also asked whether the signaling delay is significant and it was answered that the signaling delay is not long according to simulation results. It was mentioned that the signaling traffic should be given a high priority for fast delivery. In addition, there was a suggestion that QoE should be used instead of QoS. It was agreed to create a new work item An adaptive QoE control framework based on variable bit rate codec in wireless networks based on this contribution, and Mr. Ki-Jong Koo agreed to be the editor of this new work item.

Discussions
Incoming Liaison Statements
A LS on comments from ISO TC 215 on COM 16/TD 318 concerning the development of Telemedicine work was presented (TD 521/Gen).
Another LS commenting on the Roadmap Technical Paper was received from ITU-R Working Party 8A (TD 409/Gen).
Status of the roadmap
After presenting the documents for consideration, it is agreed that the roadmap for telemedicine needs some improvements: basically, a more homogeneous structure and an updated list of standards from other SDOs as CEN, ISO, IEEE, etc. The Rapporteur observed that those organisations were invited to do it through the eHealth Standardization Coordination Group (eHSCG) but few inputs were received.
Regarding the roadmap, two options are proposed to be discussed by the SG16 management:
Improve the roadmap, appointing an editor and some resources to promote also cooperation with other SDOs. This option needs a stronger commitment from ITU.
When this roadmap was started, no studies were available. However, some roadmaps and state of the art studies in the standardization e-health field have appeared with EU funds and strong involvement from specific e-health standardization bodies. Therefore, the other option is to optimise resources, select one of the existing roadmaps and analyse how ITU can be an active stakeholder in the identified topics.
During the discussion, it was mentioned that organizing another e-health workshop would help progressing the Q28 work.

TP.MMSM Service Mobility for new Multimedia Service Architecture
TD558/WP2: The Technical Paper on Service Mobility for new Multimedia Service Architecture (Final revision) identifies the possibilities to deploy service mobility with regard to the provision of Multimedia Services via underlying heterogeneous access networks. This includes but is not restricted to the Next Generation Network (NGN), defined by ITU-T.
The current revision has included different handover scenarios, including also devices with network access of different capabilities within different IP domains. Herby a strong focus is given on dynamic service adaptation according to the given restrictions of current device and access profile. Furthermore the remarks from the recent interim meeting (see chapter 1.2.2) have been included.
The described service model, functional architecture and mobility management algorithm do also include the handling of real time text in order to support the needs of handicapped and elderly persons. Based on the discussion during the Q.29 session additional text was further included into the document, which considers explicitly the needs of disabled persons.
A new work item related to "Mobility needs for disabled persons" may be generated in the future.
The Q.29/16 session recommended that TPMMSM will become approved at the SG16 plenary.
