Tile Group Signaling In Video Coding - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18336804 Titled 'Tile Group Signaling In Video Coding'
Simplified Explanation
This abstract describes a method used in a video encoder to encode a video bitstream. The video bitstream contains coded data for multiple pictures, each of which consists of at least one slice. The method involves encoding a flag that indicates whether the tile information for a picture is present in a picture parameter set or in a slice header. The tile information specifies the location of a slice within the picture.
If the flag indicates that the tile information for the picture is encoded in the picture parameter set, then the tile information is only encoded in the picture parameter set. On the other hand, if the flag indicates that the tile information for the picture is encoded in the slice header, then the tile information is only encoded in the slice header.
Finally, the method encodes the data of the picture in the video bitstream based on the tile information.
Original Abstract Submitted
A method implemented in an encoder for encoding a video bitstream that includes coded data for a plurality of pictures, each of the plurality of pictures comprises at least one slice. The method includes encoding a flag that indicates whether tile information for a picture is present in a picture parameter set or present in a slice header, where the tile information indicates a location of a slice within the picture; encoding the tile information in only the picture parameter set when the flag indicates that the tile information for the picture is encoded in the picture parameter set; encoding the tile information in only the slice header when the flag indicates that the tile information for the picture is encoded in the slice header; and encoding data of the picture in the video bitstream based on the tile information.
