Claim 7:
8. A method of encoding implemented by a video encoder, the method comprising:
determining, by the video encoder, a random access point for a video sequence;
encoding, by the video encoder, a gradual decoding refresh (GDR) picture into the video sequence at the random access point;
setting, by the video encoder, a flag to a first value to instruct a video decoder to empty any previously-decoded pictures from a decoded picture buffer (DPB);
generating, by the video encoder, a video bitstream containing the video sequence having the GDR picture at the random access point and the flag; and
storing, by the video encoder, the video bitstream for transmission toward the video decoder.
