tables for filtering operations of the intra macroblocks of the reference layer representation before resampling. From this value, the offset that is applied when addressing these tables shall be computed as: InterlayerFilterOffsetA = hnter_layer_slice_alpha_c0_offset_div2< (G-64) The value of inter_layer_slice_alpha_c0_offset_div2 shall be in the range of -6 to +6, inclusive. When inter_layer_slice_alpha_c0_offset_div2 is not present in the slice header, the value of inter_layer_slice_alpha_c0_offset_div2s shall be inferred to be equal to 0. inter_layer_slice_beta_offset_div2 specifies the offset used in accessing the deblocking filter table for filtering operations of the intra macroblocks of the reference layer representation before resampling. From this value, the offset that is applied when addressing the table of the deblocking filter is computed as: InterlayerFilterOffsetB=inter_layer_slice_beta_offset_div2<< (G-65) The value of inter_layer_slice_beta_offset_div2 shall be in the range of -6 to +6, inclusive. When hter_layer_slice_beta_offset_div2 is not present in the slice header the value of inter_layer_slice_beta_offset_div2 be inferred to be equal to 0. constrained_intra_resampling_flag specifies whether slice boundaries in the layer picture that is used for inter-layer prediction (as specified by ref_layer_dq_id) are treated similar to layer picture boundaries for the intra resampling Rec. ITU-T H.264 (01/2012) process. When constrained_intra_resampling_flag is equal to 1, disable_inter_layer_deblocking_filter_idc shall be equal to 1, 2, or 5. When constrained_intra_resampling_flagis equal to 1, a macroblock cannot be coded using the Intra Base macroblock prediction mode when it covers more than one slice in the layer picture that is used for inter-layer prediction, as specified in clause G.8.6.2. When constrained_intra_resampling_flagis not present, it shall be inferred to be equal to 0. ref_layer_chroma_phase_x_plus1_flagspecifies the horizontal phase shift of the chroma components in units of half
