  • Video Coding Bitstream Extraction With Identifier Signaling
    Publication number: 20220132170
    Abstract: A video coding mechanism is disclosed. The mechanism includes receiving an extracted bitstream that is a result of a sub-bitstream extraction process from an input bitstream containing a set of sub-pictures. The extracted bitstream contains only a subset of the sub-pictures of the input bitstream to the sub-bitstream extraction process. A flag from the extracted bitstream is set to indicate that sub-picture information related to the subset of the sub-pictures is present in the extracted bitstream. One or more sub-picture identifiers (IDs) for the subset of the sub-pictures are obtained based on the flag. The subset of the sub-pictures is decoded based on the sub-picture IDs.

    Abstract: A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a current picture including a plurality of video coding layer (VCL) network abstraction layer (NAL) units that do not have a same NAL unit type. Active entries of reference picture lists are obtained for slices positioned in a sub-picture A (subpicA) in subsequent pictures following the current picture in decoding order. The active entries do not refer to any reference picture preceding the current picture in decoding order when the subpicA at the current picture is associated with an intra-random access point (IRAP) NAL unit type. The subsequent pictures are decoded based on the reference picture list active entries. The subsequent pictures are forwarded for display as part of a decoded video sequence.
