nom syntax element is not present, the value of max_bytes_per_pic_denom shall be inferred to be equal to 2. max_bits_per_mb_denom indicates an upper bound for the number of coded bits of macroblock layer() data for any macroblock in any picture of the coded video sequence. The value of max_bits_per_mb_denom shall be in the range of 0 to 16, inclusive. Depending on max_bits_per_mb_denomthefollowing applies: - If max_bits_per_mb_denom is equal to 0, no limit is specified by this syntax element. Rec. ITU-T H.264 (01/2012) Otherwise (max_bits_per_mb_denom is not equal to 0), it is a requirement of bitstream conformance that no coded macroblock_layer() shall be represented in the bitstream by more than the following number of bits. ( 128 RawMbBits ) max_bits_per_mb_denom (E-36) Depending on entropy_coding_mode_flag, the bits of macroblock_layer( data are counted as follows: If entropy_coding_mode_flag is equal to 0, the number of bits of macroblock_layer() data is given by the number of bits in the macroblock_layer( syntax structure for a macroblock. Otherwise (entropy_coding_mode_flag is equal to 1), the number of bits of macroblock_layer() data for a macroblock is given by the number of times is called in clauses 9.3.3.2.2 and 9.3.3.2.3 when parsing the macroblock_layer(`) associated with the macroblock. When the max bits_per_mb_denom is not present, the value of max_bits_per_mb_denom shall be inferred to be equal to 1. log2_max_mv_length_horizontal and log2_max_mv_length_vertical indicate the maximum absolute value of a decoded horizontal and vertical motion vector component, respectively, in 1/4 luma sample units, for all pictures in the coded video sequence. A value of n asserts that no value of a motion vector component shall exceed the range from -2n to 2nd - 1, inclusive, in units of 1/4 luma sample displacement. The value of log2_max_mv_length_horizontal shall be in the range of 0 to 16, inclusive. The value of log2_max_mv_length_vertical shall be in the range of 0 to 16, inclusive. When log2_max_mv_length_ho
