decoding from the CVS a normative indication of the recovery point period; and
decoding an indication of the start of the recovery point period and/or an indication of the end of the recovery point period from a network abstraction layer (NAL) unit having a type of picture header, wherein
the normative indication of the recovery point period indicates that the GDR picture starts the recovery point period, and
the decoder is required to decode the CVS.
