Impact of restricting the PU and TU sizes of HEVC in a way that corresponds to the
syntax features of different prior video coding standards. The diagrams shows the corresponding
distortion-rate curves for a representative example for the scenario of entertainment applications
(

As in H.264

MPEG-4 AVC, an HEVC bitstream consists of a number of
access units, each including coded data associated with a picture that has a distinct
capturing or presentation time. Each access unit is divided into NAL units, including
one or more VCL NAL units and zero or more non-VCL NAL units. The VCL
