AVCAmd.2 (Additional Levels and Supplemental Enhancement Information) was progressed to DAM (N15420, and DoC N15421). No substantial changes were made.
Amd.2 (Sample aspect ratio and additional transfer functions, colour primaries and matrix coefficients) was progressed to the final stage. Instead of publishing as separate amendment, the FDAM text was directly integrated into a new edition (N15431, and DoC N15430). No substantial changes were made.
Most contributions in Future Video Coding were related to Requirements, except M36571, M36685, M36742, M36743. 1.1.1.1.1.1.1.1.95m36571 Approximate bit rate estimation for television services [Marek Domanski] This was presented in video plenary Wed. 11-13. It reported on consideration of broadcast, challenging content, with quality that is close to visually transparent in consumer applications. A formula is proposed that takes into account the resolution/frame rate, and the compression performance of a video codec. Number examples are reportedly not originating from experimentation, but rather from typical data rates used by broadcasters. 1.1.1.1.1.1.1.1.96m36169 On Light-field Cameras using the Example of Lytro Illum [Holger Meuel, Stephan Preihs, Jörn Ostermann] Presented in AHG pre-meeting. 1.1.1.1.1.1.1.1.97m36183 Requirements for a Future Video Coding Standard [Dan Grois on behalf of the AHG] Presented in AHG pre-meeting. 1.1.1.1.1.1.1.1.98m36440 Low bit rate UHD coding for Future Video Coding [Tomohiro Ikai, Takeshi Tsukuba, Tomoko Aono, Norio Itoh] Presented in AHG pre-meeting. 1.1.1.1.1.1.1.1.99m36603 Ericsson on future video coding requirements [Rickard Sjöberg, Jonatan Samuelsson, Kenneth Andersson] Presented in AHG pre-meeting. 1.1.1.1.1.1.1.1.100m36685 Netflix test sequences for next generation video coding [Andrey Norkin, Ioannis Katsavounidis, Anne Aaron, Jan De Cock] Presented in AHG pre-meeting, with follow-up discussion in video: see below. 1.1.1.1.1.1.1.1.101m36742 BVI_Texture UHD 120fps test sequences for HEVC and beyond [Miltiadis Alexios Papadopoulos, Fan Zhang, Dimitris Agrafiotis, David Bull, Jens-Rainer Ohm] Presented in AHG pre-meeting, with follow-up discussion in video: see below. 1.1.1.1.1.1.1.1.102m36743 Draft Call for Test Materials for Future Video Coding Standardization [Jens-Rainer Ohm] Presented in AHG pre-meeting, A Call for test materials was finalized in video: see below. 1.1.1.1.1.1.1.1.103m36762 Future video coding over 5G mobile network [K. Kawamura, S. Naito] Presented in AHG pre-meeting.
Presented in AHG pre-meeting. The topic of Future Video Coding was discussed in Video during the Monday and Wednesday plenaries, Tuesday 14:00 (joint with Requirements for preparation of October workshop), and Thursday 14:00 (for experimentation test plan). Initial viewing of new test sequences was performed Tuesday from 18:00, where, however only the sequences from m36685 were presented, presentation of sequences from m36742 was not possible due to a computer problem. For the sequences of m36685, an initial selection of clips that are likely interesting in exploring compression characteristics was made (see timecodes in N15453). For the sequences of m36742, RWTH volunteered to identify the most interesting 10 clips and make a proposal after the meeting. The work plan N15453 was set up to explore the compression characteristics of pre-selected sequences, performing HEVC encoding based on HM16.5 in LDB and RA settings, QP 17-22-27-32-37-42, results to be reported and sequences to be brought for viewing by next meeting. Volunteers (confirmed by Thursday) are: RWTH Aachen, B-COM, KDDI, Hanyang Univ., Panasonic, Ghent University, Huawei. Configuration files will be provided to participants within 2 weeks after meeting, sequences will be made available within 3 weeks to volunteers, and later to the whole community (necessary to clarify whether the MPEG SVN would have sufficient storage space). Another section on demonstrating compression characteristics was added to the Call for test sequences document (final version in N15452). Further planning was performed towards the workshop in October, based on topics suggested by AHG, including:
It was decided to organize a half day workshop (approximately 4 hrs., including a break) in the afternoon of Oct. 21. There could be speakers that cover more than one of the topics above. A breakout group was formed during the meeting for initial identification of tentative speakers, consisting of J. Ostermann, A. Aaron, J. Ohm, and J. T. Zhou. Further planning of the workshop will be performed after the meeting (see annoujncement in Requirements doc. N15341).
