Abstract:
Systems and methods may be provided for determining whether or not to output the “decoded pictures yet to be output” (DPYTBO) after decoding a random access point (RAP) picture of the second of two consecutive coded video sequences in a bitstream. The DPYTBO pictures may reside in a portion of memory coupled to a video decoder. The portion of memory may correspond to the Decoder Picture Buffer (DPB) of the video decoder. The picture resolution in the bitstream is allowed to change only at the start of a CVS. The first coded picture in a coded video sequence (CVS) may be a RAP picture. The second CVS may or may not have a picture resolution that is different from the picture resolution corresponding to the first CVS.
