  • Sub-picture Layout Signaling In Video Coding
    Publication number: 20210337200
    Abstract: A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a sub-picture partitioned from a picture and a sequence parameter set (SPS) comprising a sub-picture size and a sub-picture location. The SPS is parsed to obtain the sub-picture size of the sub-picture and the sub-picture location of the sub-picture. The sub-picture is decoded based on the sub-picture size and the sub-picture location to create a video sequence. The video sequence is forwarded for display.
