JVET-AG0068 EE2-3.2 related: On CABAC bin budget [J. Gan, Y. Yu, H. Yu (OPPO)]

This contribution proposes two aspects related to the implementation of JVET-AG0100 (EE2-3.2) with CABAC bin budget management. The first aspect proposes to change the CABAC bin check to match the increased number of flags proposed by JVET-AG0100 and brings minor loss of {0.00%, 0.04%, 0.01%} in AI relative to EE2-3.2b. The second aspect proposes to apply the same CABAC bin budget used by EE2-3.2 to TSRC and shows minor loss of {0.00%, 0.03%, 0.02%} on CTC and gain of {-0.45%, -0.49%, -0.54%} on TGM class in AI relative to EE2-3.2b.

It was commented by the proponent that the second aspect is not relevant anymore given the adoption of EE2-3.2b*. In terms of the first aspect, it was commented that there is no performance difference as this aspect is a very minor tweaking of the design.

The cross checker of the first aspect commented that the difference between this first aspect and what was adopted in EE2-3.2b* is not significant at all.

No action at this time.
