    Abstract: A video coding mechanism is disclosed. The mechanism includes receiving a sub-bitstream including: a sub-picture of a picture partitioned into a plurality of slices including a first slice, a parameter set associated with the picture and the sub-picture, and a slice header associated with the first slice. The parameter set is parsed to obtain an identifier and a length of a slice address of the first slice. A slice address for the first slice is determined from the slice header based on the identifier and the length of the slice address. The sub-bitstream is decoded to create a video sequence of sub-pictures including the first slice. The video sequence of sub-pictures is forwarded for display.

    Abstract: A video coding mechanism is disclosed. The mechanism includes receiving a bitstream including a plurality of picture parameter sets (PPSs) and a plurality of pictures at a plurality of picture sizes. A first picture size of a first picture is determined from a first PPS. The first picture is decoded at the first picture size to create a decoded reference picture. The decoded reference picture is stored in a decoded picture buffer. A second picture size of a second picture is determined from a second PPS. The second picture references the decoded reference picture according to inter-prediction. The decoded reference picture is scaled from the first picture size to the second picture size. The second picture is decoded at the second picture size based on the decoded reference picture at the second picture size.

    Abstract: A video coding mechanism is disclosed. The mechanism includes partitioning a first picture into a plurality of tiles. A group of the tiles is assigned into a first tile group. The first tile group is a rectangular shape that wraps around the first picture in a horizontal direction and a vertical direction. The first tile group is encoded into a bitstream. A flag is encoded into a parameter set in the bitstream to indicate the first tile group is an arbitrary tile group. The bitstream is stored for communication toward a decoder.

    Abstract: This application provides a media data transmission method and apparatus. The method includes: receiving, by a client, a media presentation description (MPD) file, where the MPD file includes priority indication information, and the priority indication information is used to indicate a priority or priorities of one or more overlays; and processing, by the client, the one or more overlays based on the priority indication information.

    Abstract: A method implemented by a video decoder and comprising: receiving, by the video decoder, a video bitstream comprising a picture and loop_filter_across_subpic_enabled_flag, wherein the picture comprises a subpicture; and applying a deblocking filter process to all subblock edges and transform block edges of the picture except edges that coincide with boundaries of the subpicture when loop_filter_across_subpic_enabled_flag is equal to 0. A method implemented by a video decoder and comprising: receiving, by the video decoder, a video bitstream comprising a picture, EDGE_VER, and loop_filter_across_subpic_enabled_flag, wherein the picture comprises a subpicture; and setting filterEdgeFlag to 0 if edgeType is equal to the EDGE_VER, a left boundary of a current coding block is a left boundary of the subpicture, and the loop_filter_across_subpic_enabled_flag is equal to 0.
