 data partition syntax is not present in bitstreams conforming to any of the profiles specified in Annex G. G.7.4.2.10 RBSP slice trailing bits semantics The semantics specified in clause 7.4.2.10 apply with the following modifications. Let NumBytesInVcINALunits be the sum of the values of NumBytesInNALunit for all VCL NAL units of a layer representation and let BinCountsInNALunits be the number of times that the parsing process function DecodeBin(), specified in clause 9.3.3.2, is invoked to decode the contents of all VCL NAL units of the layer representation. When entropy_coding_mode_flag is equal to 1, it is a requirement of bitstream conformance that BinCountsInNALunits shall not exceed ( 32 NumBytesInVcINALunits + RawMbBits * PicSizeInMbs 32. NOTE - The constraint on the maximum number of bins resulting from decoding the contents of the slice layer NAL units of a layer representation can be met by inserting a number of cabac_zero word syntax elements to increase the value of NumBytesInVcINALunits. Each cabac_zero_word is represented in a NAL unit by the three-byte sequence 0x000003 (as a result of the constraints on NAL unit contents that result in requiring inclusion of an remulation_prevention_three_byte for each cabac_zero_word). G.7.4.2.11 RBSP trailing bits semantics The semantics specified in clause 7.4.2.11 apply. G.7.4.2.12 Prefix NAL unit RBSP semantics The semantics specified in clause 7.4.2.12 apply. G.7.4.2.12.1 Prefix NAL unit SVC semantics The syntax element store_ref_base_pic_flag is considered as if it was present in the associated NAL unit. store_ref_base_pic_flag equal to 1 specifies that, when the value of dependency as specified in the NAL unit header is equal to the maximum value of dependency_i for the VCL NAL units of the current coded picture, an additional representation of the coded picture that may or may not be identical to the decoded picture is marked as "used for reference". This additional representation is also referred to as reference base picture and may be used for inter p
