iction, in which case prediction of macroblocks coded using Intra macroblock prediction modes only uses residual data and decoded samples from I or SI macroblock types. redundant_pic_cnt_present_flag equal to 0 specifies that the redundant pic_cr syntax element is not present in slice headers, coded slice data partition B NAL units, and coded slice data partition C NAL units that refer (either directly or by association with a corresponding coded slice data partition A NAL unit) to the picture parameter set. redundant_pic_cnt_present_flag equal to 1 specifies that the redundant_pic_cnt syntax element is present in all slice headers, coded slice data partition B NAL units, and coded slice data partition C NAL units that refer (either directly or by association with a corresponding coded slice data partition A NAL unit) to the picture parameter set. transform_8x8_mode_flag to 1 specifies that the 8x8 transform decoding process may be in use (see clause 8.5). transform_8x8_mode_flag equal to 0 specifies that the 8x8 transform decoding process is not in use. When transform_8x8_mode_flag is not present, it shall be inferred to be 0. pic_scaling_matrix_present_flagequal to 1 specifies that parameters are present to modify the scaling lists specified the sequence parameter set.pic_scaling_matrix_present_flag equal to 0 specifies that the scaling lists used for the picture shall be inferred to be equal to those specified by the sequence parameter set. When pic_scaling_matrix_present_flag is not present, it shall be inferred to be equal to 0. pic_scaling_list_present_flag[i ] equal to 1 specifies that the scaling list syntax structure is present to specify the scaling list for index i. pic_scaling_list_present_flag[i equal to 0 specifies that the syntax structure for scaling list i is not present in the picture parameter set and that depending on the value of seq_scaling_matrix_present_flag, the following applies: If seq_scaling_matrix_present_flagi is equal to 0, the scaling list fall-back rule set A as specified in Tabl
