Claim 17:
18. An encoding device, comprising:
a memory containing instructions;
a processor coupled to the memory, the processor configured to implement the instructions to cause the encoding device to:
determine a random access point for a video sequence;
encode a gradual decoding refresh (GDR) picture into the video sequence at the random access point;
set a flag to a first value to instruct a video decoder to empty any previously-decoded pictures from a decoded picture buffer (DPB); and
generate a video bitstream containing the video sequence having the GDR picture at the random access point and the flag; and

a transmitter coupled to the processor, the transmitter configured to transmit the video bitstream toward the video decoder.
