le layer representation. NOTE 2 - The set of access units that is formed by the representation of a scalable layer with sub_pic_layer_flag[ ] equal to 1 does not conform to this Recommendation | International Standard, since the primary coded VCL NAL units with quality id equal to 0 that belong to such a scalable layer representation do not cover all macroblocks of the layer pictures with dependency id equal to dependency_id[ and quality equal to 0. For the following specification in this clause, the decoding result for the representation of a scalable layer with sub_pic_layer_flag[ ] equal to 1 is the decoding result that would be obtained for the sub- picture area (as specified later in this clause) by following the decoding process in clause G.8 but ignoring the constraint that the layer representations with quality_id equal to 0 of primary coded pictures must cover all macroblocks of the corresponding layer pictures. Each scalable layer is associated with a unique layer identifier as specified later in this clause. The representation of a particular scalable layer with a particular layer identifier layerId does not include any scalable layer with a layer Rec. ITU-T H.264 (01/2012) identifier greater than layerId, but it may include scalable layers with layer identifiers less than layerId. The scalable layers on which a particular scalable layer depends may be indicated in the scalability information SEI message as specified later in this clause. NOTE 3 - When all scalable layers for which scalability information is provided in the scalability information SEI message have sub_pic_layer_flag[i equal to 0, the unique layer identifier values may be set equal to ( 128 * dependency_id + 8 * quality_id temporal_ with dependency_io quality_id, and temporal_id being the corresponding syntax elements that are associated with the VCL NAL units of a scalable layer. temporal_id_nesting_flag indicates whether inter prediction is additionally restricted for the target access unit set.
