presentation identifiers. Let depRepSet be the set of dependency representations for which (dependency_id 4) is contained in the list dqIdList. For all dependency representations of the set depRepSet, the following applies: The variable currDependencyId is set equal to the value of dependency_id for the currently considered dependency representation of the set depRepSet. The syntax elements gaps_in_frame_num_value_allowed_flagandf frame num and the derived upper-case variables PrevRefFrameNum and MaxFrameNum are the syntax elements and derived upper-case variables for the considered dependency representation. When gaps_in_frame_num_value_allowed_flag is equal to 0, the bitstream shall not contain data that result in frame nu not being equal to PrevRefFrameNum or PrevRefFrameNum + % MaxFrameNum. NOTE - When gaps_in_frame_num_value_allowed_flag is equal to 0 and frame num is not equal to PrevRefFrameNum and is not equal to PrevRefFrameNum + MaxFrameNum, the decoding process should infer an unintentional loss of pictures. When frame_num is not equal to PrevRefFrameNum and is not equal to ( PrevRefFrameNum % MaxFrameNum, the decoding process for gaps in frame num as specified in clause 8.2.5.2 is invoked. For this invocation of the process specified in clause 8.2.5.2, the modifications a) and b) specified in clause G.8.2 apply, the invocation of the decoding process for picture numbers specified in clause 8.2.4.1 is substituted with the invocation of the SVC decoding process for picture numbers specified in clause G.8.2.2 with currDependencyId and refPicListConstructionFlag equal to 0 as the inputs, and the invocation of sliding window picture marking process specified in clause 8.2.5.3 is substituted with the invocation of the SVC sliding window decoded reference picture marking process specified in clause G.8.2.4.2 with refBasePicFlag equal to 0 as the input. G.8.3 SVC intra decoding processes Clause G.8.3.1 specifies the SVC derivation process for intra prediction modes. Clause G.8.3.2 specifies the SVC intra samp
