minus1 shall be in the range of 0 to 1023, inclusive. sei_op_view_id[i] specifies the view_ic of the i-th view component to which the nested SEI message applies when Rec. ITU-T H.264 (01/2012) operation_point_flag is equal to 1. sei_op_temporal_id specifies the maximum temporal_id of the bitstream subset to which the nested SEI message applies when operation_point_flag is equal to 1. sei_nesting_zero_bit is equal to 0. H.13.2.3 View scalability information SEI message semantics When present, this SEI message shall be associated with an IDR access unit. The semantics of the message are valid for the current coded video sequence. A view scalability information SEI message contains view and scalability information for a subset of the operation points in the coded video sequence. Each operation point is associated with an operation point identifier. The sub-bitstream for an operation point is referred to as the operation point representation or the representation of the operation point. Information such as bit rate and frame rate, among others, are signalled for the representations of the subset of the operation points. NOTE 1 - Any operation point for which view and scalability information is signalled in a view scalability information SEI message (i.e. identified by a value of operation_point_id[i]) must be present in the coded video sequence. When an application keeps a view scalability information SEI message in a sub-bitstream extracted according to the process specified in clause H.8.5.3, and after the extraction any operation point for which view and scalability information is signalled in the original SEI message becomes not present in the coded video sequence, the application must change the content of the view scalability information SEI message to fulfil the condition stated by the first sentence in this note. num_operation_points_minus1 plus 1 specifies the number of operation points that are present in the coded video sequence and for which the view scalability information is signalled by the following s
