Claim 8:
9. A method of encoding a video bitstream implemented by a video encoder, the method comprising:
obtaining a reference picture list (RPL) for a second sub-picture of a mixed intra random access point (TRAP) picture, wherein the mixed TRAP picture further comprises a first sub-picture, wherein the first sub-picture and the second sub-picture are each capable of including more than one slice, and wherein the first sub-picture is an IRAP sub-picture having an instantaneous decoding refresh (IDR) network abstraction layer (NAL) unit type or a clean random access (CRA) NAL unit type and the second sub-picture is a non-IRAP sub-picture having a trailing NAL unit type;
encoding the mixed IRAP picture into a coded video bitstream; and
encoding the RPL into the coded video bitstream.
