HIGH LEVEL SYNTAX FOR VIDEO CODING AND DECODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18654626 titled 'HIGH LEVEL SYNTAX FOR VIDEO CODING AND DECODING
The method described in the abstract is about decoding video data from a bitstream, which contains video data for one or more slices. The bitstream includes a picture header with syntax elements for decoding slices, and a slice header with syntax elements for decoding individual slices. The picture header includes a syntax element indicating whether a decoding tool can be used in the picture, and if so, at least one APS ID related syntax element is parsed for the decoding tool. The decoding process also involves parsing a syntax element in the slice header to determine if the decoding tool should be used for that slice before other decoding tools are considered.
- The method involves decoding video data from a bitstream containing slices with picture and slice headers.
- The picture header includes syntax elements for decoding slices and indicates whether a decoding tool can be used.
- If a decoding tool is used, at least one APS ID related syntax element is parsed in the picture header.
- The slice header includes a syntax element to determine if the decoding tool should be used for that slice.
- The decoding process follows the syntax elements in the headers to decode the bitstream effectively.
Potential Applications: - Video streaming services - Video surveillance systems - Video editing software
Problems Solved: - Efficient decoding of video data from a bitstream - Proper utilization of decoding tools for different slices

Original Abstract Submitted
A method of decoding video data from a bitstream, the bitstream comprising video data corresponding to one or more slices. The bitstream comprises a picture header comprising syntax elements to be used when decoding one or more slices, and a slice header comprising syntax elements to be used when decoding a slice. In the picture header at least one syntax element indicating whether a decoding tool may be used in the picture. When the decoding tool is used in the picture, at least one APS ID related syntax element is parsed for the decoding tool in the picture header. The decoding also comprises parsing, in a slice header, at least one syntax element indicating whether the decoding tool is to be used or not for that slice prior to syntax elements relating to other decoding tools. A bitstream is decoded using said syntax elements.
