JVET-AN0112 Non-EE2: Coding of a coefficient level in TSRC [Y. Yu, L. Xu, J. Gan, H. Yu, D. Wang (OPPO)]
This contribution proposes to always code a significant flag with context to indicate if the coefficient level is zero or not for all coefficient levels within all non-zero subblocks of a TSRC block. In order to guarantee all significant flags coded with context and all context coded bin consumption still follows the current TSRC CABAC bin budget, this contribution proposes to reserve as many context bins as the total number of positions of all non-zero subblocks. The pre-defined CABAC bin budget for a TSRC block is updated accordingly by subtracting the number of reserved context bins and then used as a new CABAC bin budget to control the coding of other context coded syntax. In addition, all significant flags within a subblock are coded together in a separate coding pass before coding any other context coded syntax elements for a coefficient level so that there is no interleaving of context coded bins and bypass coded bins. This contribution also proposes that an adaptive Rice parameter may be used to binarize the remaining of the coefficient levels and Rice parameter is signalled at slice level if needed. For CTC application, adaptive Rice is disabled and Rice parameter 0 is used. On top of ECM-18.0, the simulation results are reported as follows.

Future meeting plans, expressions of thanks, a.o.b., and closing of the meeting
The draft of the WG 5 recommendations (see Annex C) was reviewed and approved in JVET at 1030–1100 on Saturday 11 October. In an update discussed on Sunday, the following changes (which had not yet been included in the version that was presented for information in the MPEG WG’s information exchange meeting on Saturday) were approved:
- The following recommendation was deemed necessary to be added: “WG 5 notes that action appears to not yet have been taken on some previous requests for public availability of ISO/IEC deliverables without cost, and kindly requests that ISO/IEC 23008-5:2017 (Ed. 2), ISO/IEC 23008-5:2017/Amd.1:2017, ISO/IEC 23008-8:2018 (Ed. 2), ISO/IEC 23008-8:2018/Amd1:2019, and ISO/IEC 23091-2:2025 (Ed. 3) be made freely available, considering that equivalent publications are freely available elsewhere from ITU-T as editions of ITU-T H.265.2, ITU-T H.265.1, and ITU-T H.273.” Experts were also asked to inform J.-R. Ohm and G. J. Sullivan if relevant standards were missing from this list, as far as they would be expected to be made publicly available.
- The responsible person for delivering 23090-3 is to be changed to Y.K. Wang.
- Some additions are also necessary to the resolutions of thanks, relating to multi-layer testing and...
