Q15/16, ADVANCED VIDEO CODING EXPERTS GROUP, AUGUST 22 – 24, 2000, PORTLAND, OR, USA The eleventh meeting (Meeting “K”) of the ITU-T Advanced Video Coding Experts Group was chaired by G. Sullivan (Microsoft), the Q15/16 Rapporteur. Q15-K-60d1 is the meeting report. Q15-K-00 is the document list. Q15-K-01 is the report of the May Osaka meeting. Q15-K-00 is the list of contributions to this meeting. Q15-K-TD-1 is the meeting plan. Documents for this and other meetings, and other information pertinent to the activities of the Advanced Video Coding Experts Group, can be found on the Q15/16 ftp site hosted by PictureTel corporation and managed by the Rapporteur: ftp://standard.pictel.com/video-site http://standard.pictel.com/ftp/video-site Documents for this meeting are in the 0008_Por subdirectory of the ftp site.

Reports were presented for the five ad hoc committees that were established at the previous meeting: Ad Hoc Committee Chair Report Simulation Conditions and Error Resilience Testing S. Wenger Q15-K-04 Test Model Enhancement and Software K. Hibi Q15-K-05 Development H.263++ Development G. Sullivan Q15-K-06 H.26L Development K. Hibi Q15-K-07 H.26L Network Adaptation Layer Definition T. Stockham–mer (aided by J. Pandel and Q15-K-08 G. Bäse) SIMULATION CONDITIONS AND ERROR RESILIENCE TESTING Q15-K-04 (S. Wenger, Technical University of Berlin) reports that there has been no activity of this ad hoc since the Osaka meeting. H.263++ TEST MODEL ENHANCEMENT AND SOFTWARE DEVELOPMENT Q15-K-05 (K. Hibi, Sharp Corporation) is the report of the ad hoc committee on test model enhancement and software development. No interim collaborative work was reported, but some topics of discussion for this (Portland) meeting are proposed in the report, including: • The need to add support for new H.263++ annexes in the H.263 test model • The potential promotion of the H.263 test model to a more official form such as a technical report, implementer’s guide, or appendix to the H.263 Recommendation Q15/16 embraced both of these suggestions, targeting improvement of the test model and then adopting it as Appendix II to H.263 (replacing the current non-normative recommended optional modes appendix) in the spring of 2001 (see also Workplan for H.263, below). H.263++ DEVELOPMENT Q15-K-06 (G. Sullivan, Microsoft) is the ad hoc report on H.263++ development. A major milestone was reached in July with the submission of the white contribution H.263++ Draft Annexes U (enhanced reference picture 2 Vol. 11.10 Copyright © CSR 2000 November 2000 COMMUNICATIONS STANDARDS REVIEW selection), V (data partitioned slices), and W (additional supplemental enhancement information) for Decision in Geneva in November. No significant problems were reported in the submitted text, but a couple of minor corrections might be needed in Geneva. Any changes to be suggested should be submitted as Delayed contributions for consideration in Geneva (see also H.263 proposals, below). Q15-K-42 (T. Einarsson & R. Sjöberg, Visual Technology, Ericsson Research Ericsson Radio Systems) proposes to modify Appendix II with recommended optional enhancements. The plan was discussed at the ad hoc and was modified to create a new normative Annex X (see
