JCTVC-J0371 Cross-check of JCTVC-J0179 on sao_merge_left_flag for effective Mx1 CTB coding [J. Xu (Sony)] [late]
Comment: should be considered as coding efficiency contribution.
JCTVC-J0355 AHG5, AHG6: Coding of SAO merge left and merge up flags [Koohyar Minoo, David Baylon (Motorola Mobility)]
This contribution combines 3 merge flags (Y,U,V) to 1. As result the number of context models is reduced from 3 to 1 (w/o initialization change).
0.2% Y BD-rate gain. Should be discussed together with other coding efficiency contributions.
(Rreduction of context coded bins is marginal but it is definitely not more complex.)
Decision: Adopt.
