JCTVC-M0075 On TextureRL flag context [T. Yamamoto (Sharp)]
This contribution proposes to modify the context for TextureRL flag. In the proposed context derivation, coding unit size is used instead of top and left neighbouring TextureRL flags, for the purpose of removing dependencies with neighbouring regions. Experimental results reportedly show that the impacts on the luma BD BR are; AI 2x: 0.0%, AI 1.5x: 0.0%, RA 2x: 0.1%, RA 1.5x: 0.1%, RA SNR: 0.0%, LP 2x: 0.1%, LP 1.5x: 0.2%, and LP SNR: 0.0%.
LD-B results are provided in the cross-check (0.0–0.1% impact).
Overall, the proposal looks like a good simplification to use if we do not want to instead apply some other change to obtain coding efficiency improvement. Decision (Simpl.): Adopt.
