Some terminology used in this report is explained below:
ACT: Adaptive colour transform.
Additional Review: The stage of the ITU-T "alternative approval process" that follows a Last Call if substantial comments are received in the Last Call, during which a proposed revised text is available on the ITU web site for consideration as a candidate for final approval.
AHG: Ad hoc group.
AI: All-intra.
AIF: Adaptive interpolation filtering.
ALF: Adaptive loop filter.
AMP: Asymmetric motion partitioning – a motion prediction partitioning for which the sub-regions of a region are not equal in size (in HEVC, being N/2x2N and 3N/2x2N or 2NxN/2 and 2Nx3N/2 with 2N equal to 16 or 32 for the luma component).
AMVP: Adaptive motion vector prediction.
APS: Active parameter sets.
ARC: Adaptive resolution conversion (synonymous with DRC, and a form of RPR).
