Summary of Questions' Results

Question 1/16 summary

Question 1/16 had a successful meeting and worked on the support of H.265 video in H.241/H.32x systems and on H.239 Web applications. Q1/16 reviewed some input documents pertaining to the common text ITU-T Rec. H.222.0 | ISO/IEC 13818-1. Q1/16 proposed one recommendation for Consent. The Question does not plan to hold an interim Rapporteurs meeting.

Question 2/16 summary

Question 2/16 had a very successful and productive meeting, agreeing to put two documents forward for Consent and initiate work on one new work item.  The two documents put forward for Consent are H.460.27 "End-to-end session identifier for H.323 systems" and revised H.460.22 "Negotiation of security protocols for H.225.0 call signalling".  The Question also made progress several existing work items.  The experts met for a total of six quarters, three of which were joint with Question 5/16 to progress work on Telepresence and one of which was joint with Q1/16 to progress work on H.265 support in H.323 systems. No LSs were prepared by Q2/16 at this meeting. The Question plans on holding one interim meeting collocated with other WP1/16 Questions.

Question 3/16 summary

Question 3/16 met for 8 quarters to review some 79 documents. Q3/16 continued work on a number of existing work items which has resulted in two Recommendations for Consent. Revised ITU-T H.248.78 on bearer-level application gateways and Amendment 2 to ITU-T H.248.81 on guidelines on the use of the international emergency preference scheme (IEPS) call indicator and priority indicator in ITU-T H.248 profiles.  Two new work items were initiated: Revised H.248.41 "IP domain connection package" and revised H.Sup.13 "Common ITU-T H.248 terminology – Release 2". A number of Recommendations (H.248.66, H.248.74) continue to be on hold, due to the current unavailability of the needed / referenced IETF RFCs for Consent. One liaison statement was produced.

Question 5/16 summary

Question 5/16 had a successful meeting, and progressed work on the two work items. Nine contributions on audio/video parameters and signalling were presented and discussed.  Five related contributions submitted to Q2/16 were discussed in joint Q2/16 and Q5/16 sessions.  Updated baseline text for H.TPS-AV and H.TPS-SIG was prepared and accepted.  No input liaison statements were reviewed, and no output liaison statements were 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 SG16 were to review the progress of Q6/16, JCT-VC, JCT-3V, and JPEG work, and reach AAP Consent on revised Rec. H.265 (V3), a new Rec. T.804 JPEG reference software amendment, and Approval for revised H.264.2 software with added support for 3D-HEVC. 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 two organizations, known as the Joint Collaborative Team (JCT) on Video Coding (JCT-VC) and the Joint Collaborative Team (JCT) on 3D Video Coding (JCT-3V). Meetings of the JCT-VC and JCT-3V were held in a collocated fashion with this meeting of SG16 under its auspices. The JCT-VC is tasked with development of extensions to High Efficiency Video Coding (HEVC). The JCT-3V is tasked with development of 3D video coding extensions. A meeting of MPEG was also held in CICG and ITU facilities during the current meeting of SG 16. Q6/16 is planning to hold one Rapporteur meeting, one JCT-VC meeting, and one JCT-3V meeting before the next SG16 meeting in October 2015 and also to hold a meeting of the JCT-VC and of the JCT-3V in a collocated fashion with the next SG16 meeting in October 2015 under its auspices.
