HIGH LEVEL SYNTAX FOR VIDEO CODING AND DECODING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240292036 titled 'HIGH LEVEL SYNTAX FOR VIDEO CODING AND DECODING

The abstract describes a method for decoding video data from a bitstream, which includes video data for one or more slices. The bitstream contains a picture header with syntax elements for decoding slices, and a slice header with syntax elements for decoding a slice. The picture header includes a syntax element indicating whether a decoding tool may 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 a 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.
The bitstream includes a picture header and a slice header with syntax elements for decoding.
The picture header indicates whether a decoding tool may be used in the picture.
If the decoding tool is used, at least one APS ID related syntax element is parsed.
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 to decode the bitstream effectively.

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.
