Major accomplishments

  • Consented Recommendations: 20 at this meeting (32 in 2011-03)
  • Recommendations Decided/Determined/Approved: none at this meeting
  • Recommendations agreed for Deletion: none at this meeting
  • Other texts approvederrata (0), appendices (0ß4), supplements (2ß1), implementors' guides (1ß3), technical papers (2ß6), and other documents (2ß3). Total: 5+2
  • There were no changes to the SG 16 Question set at this meeting, but the first round of discussions was held on the text of the SG 16 Questions for the next Study Period:

Contributions and discussions on the SG 16 mandate, lead SG roles and text of Question are invited during the various interim meetings as well as during the next SG 16 meeting.

  • Following the WTSA-08 mandate to coordinate its studies with ITU-T SG 9, collocated meetings of both study groups were held in the week of 21-25 November 2011. Opening plenaries of each group were staggered so delegates could attend both meetings. A joint plenary session was held on Wed 23 November. No major issues were identified, since coordination is ongoing, in particular during IPTV-GSI meetings.
  • ITU-T SG 16 also hosted the Joint Video Team on Video Coding (JCT-VC), as part of its ongoing collaboration with ISO/IEC JTC 1 / SC 29 / WG 11 for an advanced IPTV terminal and for the development of the next generation of video coding. The JCT-VC had 286 registered participants and reviewed 1045 documents in its 10 days of meeting.
  • A workshop on Telecommunication Relay Services for persons with disabilities was held on 25 November 2011 with 60 participants present. This workshop helped understanding technical, policy and end-use perspectives that will lead to standards allowing speech and hearing impaired persons to use a relay (a third-party) to fully communicate with speaking and hearing persons, despite national boundaries. The chairman's report is found in TD 436/Plen.
  • With a small amendment, ITU-T SG 16 supported the proposal to create a Collaboration on ITS Communication Standards, which will be reviewed in a meeting in Geneva, 14 December 2011.
  • Conformance and interoperability testing (CIT) activities continued in SG 16. In addition to the revision of the testing specs for the Emmy Primetime ITU-T H.264 (in H.264.1 and H.264.2), conformance checking for IPTV standards has been beefed up with two new specs plus the definition of a community-driven test case definition for ITU-T H.761. SG 16 also reviewed and found counter-productive a proposal from the ITU-T JCA-CIT on the use of mandatory Annex to Recommendations for development of CIT specs. For more details, see COM16-LS-264.
  • There were no changes in Rapporteurs and other roles: see below
  • List of pre-approved interim meetings: see related link
  • Final text of the 28 outgoing Liaison Statements: see LS database or related link (TIES account needed)
The meeting had 188 registered participants during the meeting period (compared to 175 at the last meeting). The final list of participants is available in TD 380R1/Plen.

Dates of next SG 16 meeting and interim Working Party meetings

The next meeting of ITU-T SG 16 is scheduled for Geneva, Switzerland, 30 April – 11 May 2012. The meeting will be collocated in the first week with ITU-T SG 9. ISO/IEC JTC1 SC29/ WG11 (known as MPEG) will also meet in Geneva during the first week, to facilitate joint work on video coding and on IPTV terminals.

No interim working party meetings are planned.

Summary of Questions’ Results
 Question 1/16 summary

Question 1/16 had a successful meeting and principally worked on progressing support of scalable video coding (SVC) in H.241/H.32x systems along with some discussions on future amendments to ITU-T Rec. H.222.0 | ISO/IEC 13818-1. Q1/16 proposed draft revised Recommendation H.241 for Consent.

Question 2/16 summary

Question 2/16 had a successful meeting and principally discussed the progress of the work on H.460.m-tunnel along with H.241/H.323 support of scalable video coding (SVC) (jointly with Q1/16). Q2/16 agreed to remove H.323 Annex I from the work programme confirming discussions that took place at previous meetings. Q2/16 proposed one document for Approval (H.Sup 4).

Question 3/16 summary

Question 3/16 met for six quarters to review 62 documents. Q3/16 continued work on a number of existing work items which has resulted in six Recommendations for Consent: Revised H.248.12, Revised H.248.34, new H.248.48, new H.248.50 Corrigendum 1, new H.248.79 and new H.248.83.  Two work items were put forward for approval: H-Series Supplement 2 and H.248 Sub-series Implementors’ Guide. Q3/16 started one new work item: H.248.TLS . Q3/16 also essentially completed the work on a number of Recommendations (H.248.66, H.248.74), which could not be put forward to Consent due to the current unavailability of the needed/referenced IETF RFCs. Q3/16 prepared two liaison statements.

Question 4/16 summary

Question 4/16 reviewed a contribution on an architecture which is able to provide enhanced QoS/QoE for multimedia services using the cooperation between protocol layers. It was agreed to create a work item based on the contribution. Q4/16 also reviewed a contribution on QoE enhancement using network coding for scalable video. There was one more contribution for review, which analyses various multimedia QoS issues on high speed train communications. These two contributions were considered useful to create future work items. No LSs were prepared at this meeting.

Question 5/16 summary

Question 5/16 had a successful meeting, and progressed work on the three work items.  Twenty contributions on requirements, architecture, use cases, services, and audio/video parameters were presented and discussed.  New baseline text for F.TPS-Reqs, F/H.TPS-Arch and H.TPS-AV was prepared and accepted. Incoming LS statements were reviewed, and one outgoing LS statement to SG 12 was prepared.

Question 6/16 summary

The primary goals for Question 6/16 at this meeting of SG 16 were to review the progress of Q6/16, JCT-VC, and JPEG work, reach AAP Consent on JPEG work items that have reached sufficient maturity, consider maintenance needs, and plan future work. A substantial portion of the image coding work of Question 6/16 has been conducted jointly with ISO/IEC JTC 1/SC 29/WG 1 (JPEG/JBIG). A substantial portion of the video coding work of Question 6/16 is currently being conducted jointly with ISO/IEC JTC 1/ SC 29/WG 11 (MPEG) in the Joint Collaborative Team on Video Coding (JCT-VC). A meeting of the JCT-VC was held in a co-located fashion with this meeting of SG 16 under its auspices. The JCT-VC is tasked with development of a new video coding Recommendation known as High Efficiency Video Coding (HEVC). Meetings of JPEG/JBIG and MPEG were also held nearby during the current meeting of SG 16. Q6/16 is planning to hold one Rapporteur meeting and one JCT-VC meeting before the next SG 16 meeting in April/May 2012 and to hold a meeting of the JCT-VC in a co-located fashion with the next SG 16 meeting in April/May 2012 under its auspices.

Question 7/16 summary

Question 7/16 issued a revision of the Media Coding Summary Database (MCSD) including changes in the audio, video and still image data sheets to add information on conformance and interoperability testing. The LSs related to working on IDN and especially on visual confusion in domain names were presented and noted. The future activities, especially the work programme and the question text for the next Study Period, were discussed. The Question is not planning any interim meetings.

Question 8/16 summary

Further progress was made on the GSAD technical paper. Updated text based on comments from the previous meeting was reviewed and adopted. It was agreed to include some additional graphs of the GSAD selection test results, and results of further subjective tests, before final publication of the technical paper expected for May 2012. Discussion of the future of Q08/16 indicated the possibility of re-vectoring the work to focus on the application of GSAD technology in network speech enhancement devices. No output liaisons were generated, and no interim meetings are planned.

Question 10/16 summary

Question 10/16 moved for consent a new Annex to Recommendation ITU-T G.729.1 on VAD using G.720.1 Annex A. The Question also agreed to correct the test vectors to G.711.1 Annex D and G.722 Annex B together with some minor text corrections to G.722 text. The validation means of alternative floating-point implementations of super-wideband codecs (G.711.1 Annex D, G.718 Annex B, G.722 Annex B, G.722.1 Annex C and G.729.1 Annex E) were discussed and the Question decided to investigate on a possible alternative validation tool. The basic reference solutions for G.722 encoded-domain time-scaling were reviewed. The Question reviewed 20 liaison statements, and produced five outgoing liaison statements. Discussions on the preparation for the next study period began. Q10/16 is not planning on holding any Rapporteur meeting before the next SG 16 meeting.

Question 12/16 summary

Question 12/16 had a successful meeting reviewing several contributions. Much of the meeting time was focused on the application to application signalling and interface K, as well as working through AMS communication sequence and information flow for regular multimedia communications and application handover. The experts also made progress on the draft Recommendation H.325 by issuing an updated version at this meeting. No LSs were prepared at this meeting. Q12/16 plans on holding one interim meeting, collocated with other WP2/16 Questions, and to continue regular electronic meetings, as needed.
