Abstract:
1. A method of decoding video coded using variable coded resolution, comprising, with a computing device that implements a video decoder: receiving a video bit stream, where a sequence header is integral to the video bit stream, the video bit stream having a plurality of entry point segments representing separate sub-sequences of pictures of a video sequence; decoding at least one syntax element from the sequence header, the least one syntax element from the sequence header specifying a maximum coded resolution for the video sequence; for a given one of the entry point segments, determining whether to use the maximum coded resolution for the video sequence as coded resolution for pictures of the given entry point segment and, if not, determining the coded resolution for the pictures of the given entry point segment by decoding at least one syntax element of an entry point header for the given entry point segment, the at least one syntax element of the entry point header specifying the coded resolution for the pictures of the given entry point segment; decoding said given entry point segment; and reconstructing at least part of the video sequence with the decoded entry point segment.
