Executive Summary of the ITU-T Study Group 16 Meeting
(Geneva, 30 April – 11 May 2012)
Major accomplishments
Consented Recommendations: 28 at this meeting (20 in 2011-11) Recommendations agreed for Deletion: none at this meeting Other texts approved: errata (0← 0), appendices (1← 0), supplements (0← 2), implementors' guides (1← 1), technical papers (2← 2), and other documents (5← 2). Total: 4+5 Completed the text of the SG 16 Questions for the next Study Period (TD 531R1/Plen), totalling 18 proposed new and revised Questions. Highlights:
Proposal for the mandate in the next study period was agreed, TD 530/Plen – only minor adjustments were included.
ITU-T SG 16 agreed to the ToR for the creation of a new collaborative team with MPEG – the Joint Collaborative Team on 3D video coding extensions. It will work on the creation of 3D video coding extensions for a family of codecs, including H.262, H.264 and the new HEVC (TD 532/Plen). We also agreed to issue a Joint Call for Proposals on Scalable Video Coding Extensions of High Efficiency Video Coding (HEVC) that will be carried out under the JCT-VC. The text of the preliminary call is found here. 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 30 April – 4 May 2012. Opening plenaries of each group were staggered so delegates could attend both meetings. A joint plenary session was held on Wed 2 May (report: here). 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 (MPEG) for the development of the next generation of video coding. The JCT-VC had 243 registered participants and reviewed over 500 documents in its 12 days of meeting. ITU-T SG 16 agreed with the extension of the FG-AVA period of operation till January 2013. Conformance and interoperability testing (CIT) activities continued in SG 16. Conformance checking for IPTV standards has been beefed up with one new spec for testing ITU-T H.761 Ginga/NCL. Various SG 16 Questions agreed to add a specific clause on CIT in applicable Recommendations (e.g. ITU-T G.160 and G.161 consented at this meeting). No changes in Rapporteurs and other roles, as this is the last meeting in the study period. The meeting had 181 registered participants during the meeting period (compared to 188 at the last meeting). Remote participation was provided to 18 delegates (10%). The final list of participants is available in TD 452R2/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, 14-25 January 2013. The meeting is expected be collocated in the first week with ITU-T SG 9 and IPTV-GSI. ISO/IEC JTC1 SC29/ WG11 (known as MPEG) will also meet in Geneva during the second week, to facilitate joint work on video coding and on IPTV terminals.
No interim working party meetings are planned.

Summary of Questions' ResultsQuestion 1/16 summary
Q1/16 had a successful meeting and principally worked on progressing support of scalable video coding (SVC) in H.241/H.32x systems by adding the latest approved H.264 profiles. Q1/16 reviewed some input documents pertaining to the common text ITU-T Rec. H.222.0 | ISO/IEC 13818-1 and proposed two Recommendations for Consent: H.241 Amendment 1 and H.222.0 | ISO/IEC 13818-1 4th edition (which includes ISO/IEC 13818-1 Amd.7). The Question prepared one outgoing LS jointly with Q2/16 and plans on holding one interim Rapporteurs meeting.
Question 2/16 summary
Question 2/16 concluded a successful meeting, completing work on H.460.26 to allow media to be transported over H.225.0 and initiating a new work item to amend H.460.24 with new functionality. The experts also reviewed incoming liaison statements and discussed other work items currently being progressed. The Question produced one outgoing LS together with Q1/16 and is planning on holding one interim rapporteurs meeting.
Question 3/16 summary
Question 3/16 met for six quarters to review 54 documents. Q3/16 continued work on a number of existing work items which has resulted in one Recommendation for Consent, ITU-T H.248.84 on NAT-traversal for peer-to-peer services. One new work item was initiated, H.Sup.Prio “Priority traffic treatment by H.248 Gateways. A number of Recommendations (H.248.66, H.248.74) continue to be on hold, to the current unavailability of the needed / referenced IETF RFCs for Consent. Q3/16 prepared two liaison statements.
Question 4/16 summary
Question 4/16 made progress in the work on draft new Recommendation ITU-T H.EMQ “A cooperative architecture for enhanced multimedia QoS/QoE”. In particular, the baseline text for H.EMQ was produced according to the discussion on contributions. Question 4 also reviewed the final version of Question text for the next study period. The Question is not planning on holding any interim meetings, and has not produced any outgoing liaison statements.
Question 5/16 summary
Question 5/16 had a successful meeting, and progressed work on the three work items. Twenty two contributions on requirements, architecture, audio/video parameters and potential future work items were presented and discussed. Updated baseline text for F.TPS-Reqs, F.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. The Question is planning on holding one interim Rapporteur meeting.
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 an organization known as the Joint Collaborative Team (JCT) on Video Coding (JCT-VC). A meeting of the JCT-VC was held in a collocated 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). A meeting of MPEG was also held nearby during the current meeting of SG 16. At the current meeting, interim agreement was put into place to establish an additional JCT with MPEG on 3D video coding extension development (pending confirmation by ISO/IEC JTC 1/SC 29). Q6/16 is planning to hold two Rapporteur meetings, two JCT-VC meetings, and two JCT 3D video extension meetings before the next SG 16 meeting in January 2013 and also to hold a meeting of the JCT-VC and of the JCT 3D video extension team in a collocated fashion with the next SG 16 meeting in January 2013 under its auspices (pending confirmation of meeting plans necessary to reflect WTSA decisions). The Questions prepared four outgoing Liaison Statements.
Question 7/16 summary
Question 7/16 reviewed the Media Coding Summary database (MCSD) and there are no changes from the 2011-11 version. The LS from ICANN related to the ongoing work in ICANN on IDN and especially on visual confusion in domain names was presented. The group decided to continue the work by correspondence on the scope of a work item and to send a reply LS to the ICANN. A reply LS was also sent to ITU-R SG 6 giving some feedback on the status of the work on codecs in SG 16. 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
Work on the GSTP-GSAD “Generic Sound Activity Detector” technical paper was completed. Updated material based on comments from the previous meeting, including the results of recent subjective tests using the G.720.1 VAD, was reviewed and adopted. GSTP-GSAD was submitted for Approval at this meeting. The text of the Question for the 2013-2016 Study Period remains as previously modified, with the focus on the application of GSAD technology in network speech enhancement devices. No interim meetings are planned.
