AVC. CABAC in HEVC is designed for higher throughput. For instance, the number
of context coded bins has been reduced by a factor of 8 and the CABAC bypass-mode
has been improved in terms of its design to increase throughput. Another improve-
ment with HEVC is that the dependencies between the coded data have been changed
to further increase throughput. Context modelling in HEVC has also been improved
so that CABAC can better select a context that increases efficiency when compared
to H.264/MPEG-4 AVC.
HEVC specifies 33 directional modes for intra prediction compared to the 8 di-
rectional modes for intra prediction specified by H.264/MPEG-4 AVC. HEVC also
specifies planar and DC intra-prediction modes. The intra-prediction ...
