Claim 17:
18. A decoding apparatus for decoding a video bitstream comprising a coded video sequence (CVS) of pictures beginning with a gradual decoding refresh (GDR) picture and including a recovery point picture, wherein the GDR picture starts a recovery point period and the recovery point picture ends the recovery point period, the decoding apparatus comprising:
memory; and
processing circuitry, wherein the decoding apparatus is configured to perform a process that comprises:
obtaining the video bitstream, wherein the video bitstream comprises a coded video sequence (CVS) of pictures, the CVS of pictures beginning with a gradual decoding refresh (GDR) picture and including a recovery point picture, wherein the GDR picture starts a recovery point period and the recovery point picture ends the recovery point period;
decoding from the CVS a normative indication of the recovery point period; and
decoding from a network abstraction layer (NAL) unit having a type of picture header an indication of the start of the recovery point period and/or an indication of the end of the recovery point period, wherein
the normative indication of the recovery point period indicates that the GDR picture starts the recovery point period.
