c_struct syntax element. pic_struct_present_flag equal to 0 specifies that the pic_struct syntax element is not present in picture timing SEI messages. When pic_struct_present_flag is not present, its value shall be inferred to be equal to 0. bitstream_restriction_flag equal to 1, specifies that the following coded video sequence bitstream restriction parameters are present. bitstream_restriction_flag equal to 0, specifies that the following coded video sequence bitstream restriction parameters are not present. motion_vectors_over_pic_boundaries_flag equal to 0 indicates that no sample outside the picture boundaries and no sample at a fractional sample position for which the sample value is derived using one or more samples outside the picture boundaries is used for inter prediction of any sample. motion_vectors_over_pic_boundaries_flag equal to 1 indicates that one or more samples outside picture boundaries may be used in inter prediction. When the mnotion_vectors_over_pic_boundaries_flag syntax element is not present, motion_vectors_over_pic_boundaries_fla value shall be inferred to be equal to 1. max_bytes_per_pic_denom indicates a number of bytes not exceeded by the sum of the sizes of the VCL NAL units associated with any coded picture in the coded video sequence. The number of bytes that represent a picture in the NAL unit stream is specified for this purpose as the total number of bytes of VCL NAL unit data (i.e., the total of the NumBytesInNALunit variables for the VCL NAL units) for the picture. The value of max_bytes_per_pic_denom shall be in the range of 0 to 16, inclusive. Depending on max_bytes_per_pic_denom the following applies: If max_bytes_per_pic_denom is equal to 0, no limits are indicated. Otherwise (max_bytes_per_pic_denom is not equal to 0), it is a requirement of bitstream conformance that no coded picture shall be represented in the coded video sequence by more than the following number of bytes. ( PicSizeInMbs * RawMbBits ) (8 * max_bytes_per_pic_denom (E-35) When the max_bytes_per_pic_de
