al to 43) is present in an SEI NAL unit, it shall be the only SEI message in the SEI NAL unit. H.13.2.1 Parallel decoding information SEI message semantics The parallel decoding information SEI message may be associated with any access unit. The information signalled in the SEI message applies to all the access units from the access unit the SEI message is associated with to the next access unit, in decoding order, containing an SEI message of the same type, exclusively, or to the end of the coded video sequence, whichever is earlier in decoding order. Some view components for which the parallel decoding information is signalled in a parallel decoding information SEI message may not be present in the coded video sequence. seq_parameter_set_id specifies a subset sequence parameter set that contains the inter-view dependency relationship information. The value of seq parameter_set_id shall be equal to the value of seq_parameter_set_id in the picture parameter set referenced by a view component of the primary coded picture of the access unit containing the parallel decoding information SEI message. The value of seq_parameter_set_id shall be in the range of 0 to 31, inclusive. NOTE 1 - The inter-view dependency relationship is signalled in the sequence parameter set MVC extension, which is identical for all subset sequence parameter sets that may be activated during the decoding process for the coded video sequence. odi_init_delay_anchor_minus2_10[i][j] specifies the unavailable reference area in the view component with view id equal to anchor_ref_10[i][j] that shall not be used for inter-view reference by the coded anchor view component with view equal to where anchor_ref_10[i][j] and view_id[i] are both from the MVC sequence parameter set that has a sequence parameter set identifier equal to the syntax element seq_parameter_set_id contained in the current SEI message. The unavailable reference area is a rectangular area with coordinates (0, (CurrMbAddr +pdi_init_delay_anchor_minus2_10[i][j]+2)*16) as the top left c
