r picture. The macroblock addresses are derived from the first macroblock address in a slice (as represented in the slice header) and the macroblock to slice group map. G.3.57 slice group: A subset of the macroblocks or macroblock pairs of a picture or layer picture. The division of the picture or layer picture into slice groups is a partitioning of the picture or layer picture. The partitioning is specified by the macroblock to slice group map. G.3.58 spatial intra prediction: See intra-layer intra prediction. G.3.59 sub-bitstream: A subset of a bitstream. A sub-bitstream is also referred to as bitstream subset. G.3.60 subset: A subset contains only elements that are also contained in the set from which the subset is derived. The subset may be identical to the set from which it is derived. G.3.61 subset sequence parameter set: A syntax structure containing syntax elements that apply to zero or more layer representations with the dependency_id syntax element not equal to 0 or the quality syntax element not equal to 0 as determined by the content of a seq_parameter_set_id element found in the picture parameter set referred to by the pic_parameter_set_id.s syntax element found in each slice header of EI, EP, and EB slices. G.3.62 SVC sequence parameter set: A collective term for sequence parameter set or subset sequence parameter set. G.3.63 SVC sequence parameter set RBSP: A collective term for sequence parameter set RBSP or subset sequence parameter set RBSP. G.3.64 target dependency representation: The dependency representation of a coded picture that is associated with the largest value of the dependency_id syntax element for all dependency representations of the coded picture. Rec. ITU-T H.264 (01/2012) G.3.65 target layer representation: The layer representation of the target dependency representation of a coded picture that is associated with the largest value of the quality_id syntax element for all layer representations of the target dependency representation of the coded picture.
