HIGH LEVEL SYNTAX FOR VIDEO CODING AND DECODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18654638 titled 'HIGH LEVEL SYNTAX FOR VIDEO CODING AND DECODING
The patent application describes a method for decoding video data from a bitstream, which includes video data corresponding to one or more slices. The bitstream contains a picture header with syntax elements for decoding slices, as well as 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. Additionally, the slice header includes a syntax element indicating whether the decoding tool is to be used for that slice before other decoding tools are considered.
- The method involves parsing syntax elements in the picture header and slice header to determine the use of decoding tools.
- The picture header includes syntax elements related to the use of a decoding tool in the picture.
- The slice header includes syntax elements indicating whether the decoding tool is to be used for that specific slice.
- The decoding process involves using the parsed syntax elements to decode the bitstream.
- This method allows for efficient decoding of video data by determining the use of decoding tools based on syntax elements in the headers.
Potential Applications: - Video streaming services - Video surveillance systems - Video editing software
Problems Solved: - Efficient decoding of video data - Optimal use of decoding tools - Enhanced video quality
Benefits: - Improved video decoding process - Better utilization of decoding tools - Enhanced video viewing experience
Commercial Applications: Title: "Enhanced Video Decoding Method for Improved Efficiency" This technology can be used in various commercial applications such as video streaming services, video surveillance systems, and video editing software to enhance the decoding process and improve overall video quality. The market implications include increased efficiency in video processing, leading to better user experiences and potentially higher customer satisfaction.

How does the method described in the patent application improve the decoding process of video data? - The method improves the decoding process by efficiently determining the use of decoding tools based on syntax elements in the picture and slice headers. 2. What are the potential commercial applications of this technology? - The technology can be applied in video streaming services, video surveillance systems, and video editing software to enhance the decoding process and improve video quality.
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.
