Summary of Questions’ Results

Question 1/16 Summary
Question 1/16 reviewed several matters in relation with H.241, allowing, in particular, for the negotiation of video submodes of H.264 encoding, and H.324 Annex K. T.128 was also revised at this meeting. Question 1 proposed one Recommendation, one Amendment and one Corrigendum for Consent (H.222.0 Cor. 1, H.241 Amd. 1, T.128).

Question 2/16 Summary
Question 2/16 had a successful meeting, reaching consensus on a new revised Recommendation H.245, which, among other things, adds new functionality for improved quality of service features for H.323. The experts also made progress on revising Recommendations H.323 and H.225.0, with an intent to publish a new version of H.323 and H.225.0 at the next Study Group meeting. Finally, Question 2 revised the H.323 System Implementors’ Guide and agreed to approve a new version at this meeting.

Question 3/16 Summary
Question 3/16 met for 12 quarters to review some 158 documents. Q3/16 continued work on a number of existing work items which has resulted in 11 Recommendations for Consent: H.248.11 Corrigendum1, Revised H.248.37, H.248.41 Amendment 1, New H.248.43, Revised H.248.47, New H.248.52, New H.248.53, New H.248.55, New H.248.57, New H.248.58 and New H.248.62. In addition to these Recommendations Q.3 prepared 7 documents for approval: H.248.1v3 Amendment 1, Revised H-Series Supplement 2 “Packages Guide”, Supplement 7 “Establishment Procedures for H.248 Control Association”, Supplement 8 “Synchronized time in H.248”, Supplement 9 “H.248 ETS/IEPS operation”, H.248 Sub-Series Implementors’ Guide, and the H.248.1 version 2 Implementors’ Guide. Q.3 started 2 new work items: H.248.PIPA and H.248.TDR. Q.3 prepared 5 liaison statements.

The Rapporteur would like to thank the contributors to the Q.3 work and especially the editors for their work in preparing Recommendations.

Question 4/16 Summary
Question 4/16 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 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 6/16 Summary
A substantial portion of the work of Question 6/16 is also conducted jointly with ISO/IEC JTC 1/SC 29/WG 11 (MPEG) in an organization known as “the JVT” (Joint Video Team) and with ISO/IEC JTC 1/SC 29/WG 1 (JPEG/JBIG). A meeting of the JVT was held in a co-located fashion with this meeting of SG 16. The ongoing JVT work is currently concentrated on the maintenance and development of extensions for Rec. H.264 (a Twin Text Recommendation with ISO/IEC 14496-10) including multi-view video coding (MVC) and supplemental enhancement information (SEI). The primary goals for Q.6/16 at this meeting of SG 16 were to review the progress of Q.6 and JVT work, to reach AAP Consent on those work items that have reached sufficient maturity, and to plan future work. AAP Consent was reached on three Recommendations relating to Rec. H.264 video coding, consisting of corrigendum corrections and clarifications to Rec. H.264 itself and updating of the associated Recs. H.264.1 (conformance) and H.264.2 (reference software) to include general improvements and support of recent extensions. In work related to JPEG 2000 still image coding (common text with ISO/IEC 15444), AAP Consent was reached for two modifications to the Rec. T.808 interactive protocol (a clarification corrigendum and an amendment specifying extensions to 3D data).

Question 8/16 Summary
An update was provided on the work underway with SG12 (Q7/12 and Q9/12) to validate the performance metric planned to be used for specifying GSAD performance in the GSAD codec independent layer ToR. It is expected that a subjective database and comparison with objective metrics will be available for a joint session of Q7/12 and Q9/12 to be held during the May 2008 meeting of SG12, to which members of Q8/16 have also been invited. Further progress was made in updating the GSAD codec independent layer ToR.

Question 9/16 Summary
The results of the EV-VBR optimization/characterization phase I tests were reviewed. The codec passed 78 out of 80 requirements from the ToRs in two laboratories, and there were no systematic failures of any of the requirements in two laboratories. In response to concerns expressed about the performance of the G.722.2 Interoperability and DTX modes of the codec, it was agreed to add some additional test conditions in the optimization/characterization phase II. The text of draft new G.VBR-EV was Consented at this meeting as ITU-T Rec. G.718. It was agreed to begin work on a floating point annex to G.718. Q.9/16 prepared a liaison statement providing Q7/12 with a modified list of Characterization/Optimization Phase II test conditions and a request for Q7/12 to draft a Characterization/Optimization Phase II Test Plan. In addition, a request has been made for Q9/12 and Q7/12 to review subjective and objective scores of the clean speech conditions of the Characterization/Optimization Phase I tests and to provide guidance over the suitability of employing objective methods to validate a floating point annex to G.VBR-EV. A reply liaison statement was sent to 3GPP2 TSG-C, concerning interoperability between ITU’s EV-VBR and 3GPP2’s EVRC-WB coders.

Question 10/16 Summary
The group agreed to move for Consent under AAP new G.719 (ex G.722.1FB), an amendment to G.729.1 for a new annex on DTX/CNG and corrections to main body and Annex B, and a corrigendum to G.722.1. The standardization of floating point implementation of G.729.1 DTX/CNG has been launched and those of G.711.1 and G.719 are ongoing. The objectives scores and subjective scores of their fixed point characterization phases have been collected for SG 12 analysis. The Consent meeting for these floating point versions is foreseen at next WP3/16 meeting (3 October 2008). Step 2 characterization phases of G.711.1 and G.719 have been prepared. The ToR of superwideband extension to G.711.1 and G.722 (mono part) have been approved and the qualification phase launched. The work on G.711 lossless compression has well progressed and the Consent meeting is foreseen at next SG16 plenary meeting. A new tool for stereo processing has been provided. The Question prepared liaison statements to SG 12, ITU-R W6G and ISO/IEC MPEG. The work progress will be reviewed at next Q10/16 Rapporteur meeting (end of September 2008).

Joint Questions 11/16 and 14/16 Summary
At this meeting Question 11/16 and 14/16 met jointly. The goal for this meeting was to continue with the development of Recommendations V.151, V.152 and V.IP2IP-VxF and complete the Draft for new Recommendation V.AMAT (V.254). Unfortunately no contributions or updated editor drafts were available. The Rapporteur will coordinate renewed effort to complete these Recommendations for the next meeting of SG 16.

Question 12/16 Summary
Question 12/16 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 15/16 Summary
At this meeting, Question 15/16 advanced the work on drafting new ITU-T Rec. I.733 (Voice on ATM Multiplexing Equipment), but due to the availability of proponent, the consensus could not be obtained, and the group postponed the consent of text at next study meeting. The group also examined the Text of Question for next study period, and completed the text. One interim meeting is proposed.

Question 16/16 Summary
Further progress was made on drafting text for revised ITU-T Rec. G.168 (Echo Cancellers), new ITU-T Rec. G.160 (Voice Enhancement Devices) and new Annex E to G.168 (Embedded Echo Cancellers). G.160 was put forward for consent at this meeting. A new Implementors’ Guide for G.168 was developed and was approved at this meeting. One interim meeting is proposed.

Question 17/16 Summary
At this meeting, Question 17/16 advanced the work on drafting new ITU-T Rec. G.IP2IP (Signal processing functionality and performance of an IP-to-IP Voice Gateway, optimised for the transport of voice and voiceband data), and advanced the draft text version to 1.8. The group also examined the Text of Question for next study period, and completed the text. One interim meeting is proposed.

Question 18/16 Summary
At this meeting, Question 18/16 advanced the work on drafting new Recommendation G.UCPSPNE “SPNE mechanisms/auxiliary functions”, new Recommendation G.mdcspne “Mechanism for dynamic coordination of SPNE”, revised Recommendation G.161 “Interaction aspects of signal processing network equipment” and new Recommendation G.spne “Signal Processing Network Equipment”. Draft new Recommendation G.UCPSPNE has been Consented as G.776.2. One liaison statement was sent to SG 11. The Question plans to hold one interim meeting.

Question 20/16 Summary
Question 20/16 reviewed some of the results of the ongoing activities in TSAG, in the IPTV-GSI and NGN-GSI. Specific actions for coordination and harmonization of the work performed on these topics have been discussed under the relevant SG 16 Questions. In addition, SG 16 has addressed in two Joint Working Party meetings the future of SG16, in particular the different options under discussion at TSAG and the revision of the set of Questions for the next Study Period. ICT and climate change was also discussed under Q20/16 and an ad hoc group was set up to further investigate the impact of present and future MM standards on the climate change.

Question 21/16 Summary
Question 21/16 discussed architecture aspects of multimedia application. After discussion based on contributions and liaison statements, it was agreed to propose draft new Recommendations H.622 (ex H.ghna) and H.621 (ex H.mid, in coordination with Q22/16) 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, 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 Contributions 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 Contributions. 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 Recommendations are ready for Consent. 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 23/16 Summary
The group further progressed the work to define features for the NGN speech and audio codec to identify exactly which ones would be required by NGN applications and services. Concerning IPTV, joint meetings were held with Q13/16 and Q6/16. Many items of the joint superwideband extension of G.EV-VBR and G.729.1 were reviewed, and the ToR was slightly modified to reflect changes agreed during the last few months; the time schedule was also revised. Q23 also reviewed the current status of the MCSD database to incorporate G.711.1 data.

Question 24/16 Summary
Question 24/16 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
Question 25/16 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 26/16 Summary
Question 26/16 received no contributions to its work but dealt with a number of liaison statements. The formation of the new JCA-AHF was discussed. We also analysed some of the suggested restructuring proposals from the point of view of accessibility. We assisted Q.29/16 and Q.12/16 in their work. We started work on a document that will give guidance about relay services. We amended the text of the Question and revised the work programme. Work will continue by correspondence.

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 e-Health 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 6/13 as well as Questions 2 and 5/19 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 Q29/16 to progress its work on the technical paper TP.MMSM (Service mobility for new multimedia service architecture), which was approved by SG 16 at its closing Plenary.

Ad hoc group on vehicle gateway platform – ToR and roadmap 

Vehicle Gateway is intended to provide and support telecommunications using the network environment within the car and to outside (vehicle to vehicle and vehicle to infrastructure), so the Vehicle Gateway has a significant role in the vehicle supporting the ubiquitous connectivity under the global heterogeneous environments. Therefore supporting global seamless ITS services/applications, global standards for Vehicle Gateway should be developed to allow all consumer devices working plug-and-play in all vehicles. This ad hoc group will start work foreseen in the context of proposed new Question QD4/16 (provisional number pending consideration of WTSA-08).

Study items

Study items to be considered include, but are not limited to:
  • Definition and the scope of Vehicle Gateway
  • Functions and service requirements of Vehicle Gateway Platform to support vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) telecommunications
  • Functional architectures and mechanisms of Vehicle Gateway
  • Use cases and scenarios working of Vehicle Gateway as a bridge between the cars(V2V) and between the car and infrastructure(V2I)
  • Study enhancements required to provide energy savings and reducing the gas emission directly or indirectly including support of emergency and early warning services of traffic accidents

Tasks include but are not limited to:
  • Studies on the requirements in terms of services and functions to support V2V and V2I
  • Studies on the functions of Vehicle Gateway and its reference model(s)
  • Studies on the open interface between in-vehicle network and ICT devices
  • Studies on the relevant necessary protocols to support vehicle oriented services/applications
Draft Roadmap for development of Vehicle Gateway related standards
