US Patent 9860540 Inference of nooutputofpriorpicsflag in video coding

An apparatus for coding video information according to certain aspects includes a processor configured to determine a value of a flag associated with a current picture of a current layer to be decoded, the flag indicating whether pictures in a decoded picture buffer (DPB) should be output, wherein the current picture is an intra random access point (TRAP) picture that starts a new coded video sequence (CVS) and wherein the determination of the value of the flag is based on at least one of: (1) the chroma format of the current picture and the chroma format of the preceding picture, (2) the bit depth of the luma samples of the current picture and the bit depth of the luma samples of the preceding picture, or (3) the bit depth of the chroma samples of the current picture and the bit depth of the chroma samples of the preceding picture.
