r 5 (via the value of pic_parameter_set_id) in the same access unit. The value of seq_parameter_set_id in a buffering period SEI message that is included in a scalable nesting SEI message and is associated with a particular value of DQId shall be identical to the value of seq_parameter_set_id in the picture parameter set RBSP that is referred to by coded slice NAL units with the particular value of DQId (via the value of pic_parameter_set_id) in the same access unit. The active layer SVC sequence parameter set RBSPs for different values of DQId may be the same SVC sequence parameter set RBSP. The active SVC sequence parameter set RBSP and an active layer SVC sequence parameter set RBSP for a particular value of DQId may be the same SVC sequence parameter set RBSP. When the active SVC sequence parameter set RBSP for a coded picture is a sequence parameter set RBSP, any sequence parameter set RBSP with the value of seq_parameter_set_id for the active SVC sequence parameter set RBSP for the coded picture shall have the same content as that of the active SVC sequence parameter set RBSP for the coded picture unless it follows the last access unit of the coded video sequence containing the coded picture and precedes the first VCL NAL unit and the first SEI NAL unit containing a buffering period SEI message (when present) of another coded video sequence. When the active SVC sequence parameter set RBSP for a coded picture is a subset sequence parameter set RBSP, any subset sequence parameter set RBSP with the value of parameter_set_i for the active SVC sequence parameter set RBSP for the coded picture shall have the same content as that of the active SVC sequence parameter set RBSP for the coded picture unless it follows the last access unit of the coded video sequence containing the coded picture and precedes the first VCL NAL unit and the first SEI NAL unit containing a buffering period SEI message (when present) of another coded video sequence. For each particular value of DQId, the following applies: When the active
