Organisation internationale de normalisation

NSQT: Non-square quadtree.

NUH: NAL unit header.

NUT: NAL unit type (as in AVC and HEVC).

OBMC: Overlapped block motion compensation.

PCP: Parallelization of context processing.

POC: Picture order count.

PoR: Plan of record.

PPS: Picture parameter set (as in AVC and HEVC).

QM: Quantization matrix (as in AVC and HEVC).

QP: Quantization parameter (as in AVC and HEVC, sometimes confused with quantization step size).

QT: Quadtree.

RA: Random access – a set of coding conditions designed to enable relatively-frequent random access points in the coded video data, with less emphasis on minimization of delay (contrast with LD).

RADL: Random-access decodable leading.

RASL: Random-access skipped leading.
