Claim 18:
19. An encoding apparatus for encoding a bitstream, the encoding apparatus comprising:
memory; and
processing circuitry, wherein the encoding apparatus is configured to:
determine that a particular picture in a coded video sequence (CVS) of pictures in the bitstream is to be a start of a recovery point period, wherein a last coded picture in decoding order in the recovery point period is to be a recovery point picture;
defining the particular picture as a gradual decoding refresh (GDR) picture such that the CVS begins with the GDR picture and includes the recovery point picture;
determining the recovery point picture; and
encoding in the CVS a normative indication of the recovery point period in the bitstream, wherein
the normative indication of the recovery point period comprises information indicating that the recovery point period starts with the GDR picture, and
an indication of the start of the recovery point period is encoded in a network abstraction layer (NAL) unit having a type of picture header and/or an indication of the end of the recovery point period is encoded in the NAL unit.
