INDEPENDENT SUBPICTURE SIGNALING IN VIDEO CODING

Abstract:

A method of decoding video data, the method comprising: obtaining, from a bitstream that comprises an encoded representation of the video data, a first syntax element indicating a number of subpictures in each picture in a coded layer video sequence (CLVS); based on the first syntax element indicating that the number of subpictures in each picture in the CLVS is greater than 1, obtaining, from the bitstream, a second syntax element that specifies whether all subpicture boundaries in the CLVS are treated as picture boundaries; and based on the second syntax element specifying that all subpicture boundaries in the CLVS are treated as picture boundaries, decoding each subpicture in each of the pictures in the CLVS as a separate picture.
