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. The Question reached AAP Consent on revised Recs. H.264 (V10), H.264.1 (V6), H.264.2 (V6), H.265.2 (V2) and T.800 (V2). 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 a nearby hotel during the current meeting of SG 16. At this meeting the amount of activity in Q6/16 on exploration studies toward next-generation video coding with capabilities beyond HEVC continued to grow substantially, and a new agreement was reached to collaborate with MPEG on these studies in an informal Joint Video Exploration Team (JVET). Q6/16 is planning to hold one Rapporteur meeting, one JCT-VC meeting, and one JCT-3V meeting before the next SG16 meeting in June 2016 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 June 2016 under its auspices. The Question prepared five outgoing Liaison Statements. A proposed revision of the text description for Question 6/16 was also produced for consideration for the next study period, including a merging of some responsibilities formerly in the domain of Question 7/16.

Question 7/16 summary

Q7/16 which addresses mainly coordination aspects of media coding did not receive any contributions and no sessions were held during the SG16 meeting.

Question 10/16 summary

Question 10/16 reviewed the texts on ITU-T G.191 “Software tools for speech and audio coding standardization” and decided to move the target Consent date until the next SG16 meeting in May 2016. The texts on super wideband extension to G.718, super wideband extension to ITU-T G.729.1 and G.722 encoded-domain time-scaling were reviewed and decided to remove the work items related to these texts from the SG16 work programme due to a lack of Contributions. For the next Study Period the future of Q10/16 was discussed and it was proposed to merge Q10/16, Q7/16, Q15/16 and Q18/16 into one Question. This first draft proposal will be sent to the next TSAG meeting for information. No outgoing liaison was prepared and Q10/16 is not planning on holding any Rapporteur meetings before the next SG 16 meeting.
