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

This abstract first appeared for US patent application 17913074 titled 'HIGH LEVEL SYNTAX FOR VIDEO CODING AND DECODING

Simplified Explanation

The patent application describes a method for decoding video data from a bitstream, where the bitstream contains video data for one or more slices, and each slice may have one or more tiles. The bitstream includes a picture header and a slice header, both containing syntax elements for decoding the slices.

  • The method involves parsing the syntax elements while decoding a slice.
  • If a slice includes multiple tiles, the parsing of a syntax element indicating the address of a slice is skipped if a syntax element is found that signals a picture header in the slice header.
  • The bitstream is then decoded using the parsed syntax elements.

Potential Applications

  • Video streaming and playback applications.
  • Video compression and encoding technologies.
  • Video editing and post-production software.

Problems Solved

  • Efficient decoding of video data from a bitstream with multiple slices and tiles.
  • Reducing the parsing overhead by omitting unnecessary syntax element parsing.

Benefits

  • Improved video decoding performance.
  • Reduced computational requirements for decoding video data.
  • Enhanced efficiency in video processing and playback.


Original Abstract Submitted

There is provided a method of decoding video data from a bitstream, the bitstream comprising video data corresponding to one or more slices. Each slice may include one or more tiles. 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. Decoding a slice, comprises parsing the syntax elements. In a case where a slice includes multiple tiles, the parsing of a syntax element indicating an address of a slice is omitted if a syntax element is parsed that indicates that a picture header is signalled in the slice header. The bitstream is decoded using said syntax elements.
