HIGH LEVEL SYNTAX FOR VIDEO CODING AND DECODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18654656 titled 'HIGH LEVEL SYNTAX FOR VIDEO CODING AND DECODING
The abstract describes a method of decoding video data from a bitstream, which includes syntax elements in the picture header and slice header to be used during decoding. The decoding process involves determining whether a decoding tool may be used in the picture and parsing related syntax elements if the tool is used. Additionally, the method includes parsing syntax elements in the slice header to determine if the decoding tool should be used for that particular slice.
- The method involves decoding video data from a bitstream by utilizing syntax elements in the picture header and slice header.
- It includes determining the use of a decoding tool in the picture and parsing related syntax elements if the tool is used.
- The method also involves parsing syntax elements in the slice header to decide whether the decoding tool should be used for a specific slice.
- By using these syntax elements, the bitstream can be decoded effectively.
Potential Applications: - Video streaming services - Video surveillance systems - Video editing software
Problems Solved: - Efficient decoding of video data from a bitstream - Improved utilization of decoding tools - Enhanced video quality and playback experience

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.
