Abstract
A system for decoding a video bitstream includes receiving a frame of the video that includes at least one slice and at least one tile and where each of the at least one slice and the at least one tile are not all aligned with one another.
Claims19
A processor based method for decoding a video bitstream comprising:
- (a) receiving a base bitstream including a plurality of base frames for said video bitstream;
- (b) receiving at least one enhancement layer including a plurality of enhancement frames for said video bitstream, where said plurality of enhancement frames include a hierarchical coding structure;
- (c) initializing an initial value for a context modeler by selecting one of a plurality of predetermined initial values available to said decoder, selection using said hierarchical coding structure, and selection using at least one of a deltaQP characteristic, picture order count, or temporalID characteristic;
- (d) based upon said initial value and said initializing, decoding said enhancement bitstream.
