JVET-R0485 AHG9: Combination of JVET-R0049 and JVET-R0271 with Inverse Semantics and improved SPS signalling [K. Naser, F. Le Léannec, T. Poirier, M. Kerdranvat (InterDigital)] [late]
Similar to JVET-R0483, this contribution also combines method 1 of JVET-R0049 with variation 2 and variation 3 of JVET-R0271. However, the new added SPS flag for controlling TSRC is considering as described in the meeting notes (d6) “sps_ts_residual_coding_disabled_flag” instead of “sps_ts_residual_coding_slice_disabled_present_flag”. It is asserted that this changes the semantics of the new added flag changes also the number of bits signalled at SH when the same analysis is performed as in JVET-R0483. This document provides also further analysis about the all possible combinations that can be exercised by the encoder.

The contribution proposes to introduce an SPS flag that disables TSRC at sequence level.
Several experts said they would not support such a change. No consensus could be reached.
No action was taken on this.
