 the transform coefficient decoding process and picture construction process prior to deblocking filter process as specified in clause 8.5 shall be applied. qpprime_y_zero_transform_bypass_flag equal to 0 specifies that the transform coefficient decoding process and picture construction process prior to deblocking filter process shall not use the transform bypass operation. When qpprime_y_zero_transform_bypass_flag is not present, it shall be inferred to be equal to 0. seq_scaling_matrix_present_flag equal to 1 specifies that the flags seq_scaling_list_present_flag[i] for i = 0..7 or i = 0..11 are present. seq_scaling_matrix_present_flag equal to 0 specifies that these flags are not present and the sequence-level scaling list specified by Flat 4x4 16 shall be inferred for 0..5 and the sequence-level scaling list specified by Flat_8x8_16 shall be inferred for i = 6..11. When seq_scaling_matrix_present_flag is not present, it shall be inferred to be equal to 0. The scaling lists Flat_4x4_16 and Flat_8x8_16 are specified as follows: Flat_4x4_16[k]=16, with 0..15, (7-7) Flat_8x8_16[k]=16 with k = 0..63. (7-8) seq_scaling_list_present_flag[i I equal to 1 specifies that the syntax structure for scaling list i is present in the sequence parameter set. seq_scaling_list_present_flag| i ] equal to 0 specifies that the syntax structure for scaling list i is not present in the sequence parameter set and the scaling list fall-back rule set A specified in Table 7-2 shall be used to infer the sequence-level scaling list for index i.
