ITU-T H.264 (01/2012) H.13.2.7 View dependency change SEI message semantics This SEI message indicates that the view dependency information changes starting with the current access unit containing the SEI message and is always interpreted with respect to the active MVC sequence parameter set. When present, the view dependency change SEI message applies to the target access unit set that consists of the current access unit and all the subsequent access units, in decoding order, until the next view dependency change SEI message or the end of the coded video sequence, whichever is earlier in decoding order. If, according to the view dependency information indicated in the active MVC sequence parameter set, view component A does not directly or indirectly depend on view component B and vice versa, the view dependency change SEI message shall not specify view dependency relationship between view components A and B. NOTE 1 - The dependent views for any view are always a subset of those indicated by the active MVC sequence parameter set. NOTE 2 - View dependency change SEI messages do not have a cumulative effect. Some of the views indicated by the following syntax elements may not be present in the target access unit set. 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 view dependency change SEI message. The value of seq_parameter_set_id shall be in the range of 0 to 31, inclusive. anchor_update_flag equal to 1 indicates that there are updates for the dependencies for anchor view components relative to the dependencies defined in the active MVC sequence parameter set. anchor_update_flag equal to 0 indicates that there is no change for the dependencies for anchor view components relative to the dependencies defined
