Describe the coding tree unit as replacement for the macroblock in the
HEVC codec. Highlight a key difference of the HEVC codec to predecessors
like AVC(H.264) to give a better overview of the differences between the
coding standards.

The codec has multiple identifiers H.265 (ITU-T), MPEG-H Part 2 (ISO),

Also nearly all other related drivers use the term HEVC instead of H265.
