VIDEO ENCODING AND DECODING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18672664 titled 'VIDEO ENCODING AND DECODING

The abstract describes a patent application for a decoder that can decode a picture from a bitstream by partitioning it into tile groups and mapping tile group index values to the number of tiles to be decoded for each group.

  • The decoder decodes parameter set data to create a size mapping for the tiles in each group.
  • It then decodes coded tile groups by determining the size of each group based on the index value and size mapping.
  • The decoder decodes the number of coded tiles specified by the size mapping to form the decoded picture.

Potential Applications: - Video decoding systems - Image processing applications - Multimedia streaming services

Problems Solved: - Efficient decoding of pictures from bitstreams - Improved processing of partitioned images - Enhanced video quality and resolution

Benefits: - Faster decoding of images - Better utilization of system resources - Higher quality video output

Commercial Applications: Title: "Advanced Video Decoding Technology for Enhanced Multimedia Streaming" This technology can be used in video streaming services, video conferencing platforms, and digital media players to improve the efficiency and quality of video decoding processes.

Questions about the technology: 1. How does this decoder improve the decoding process for partitioned images? - The decoder efficiently maps tile group index values to the number of tiles to be decoded, streamlining the decoding process for complex images. 2. What are the potential applications of this technology in the multimedia industry? - This technology can be applied in various multimedia applications such as video streaming, image processing, and video conferencing to enhance the decoding and processing of multimedia content.


Original Abstract Submitted

A decoder can be configured to decode a picture from a bitstream in which the picture is partitioned into a plurality of tile groups. The decoder can decode a first part of the bitstream (including parameter set data) to form a size mapping that maps a tile group index value to a number of tiles to be decoded for a first tile group. The decoder can further decode a second part of the bitstream (including includes coded tile groups) by: decoding, from a tile group header in a first coded tile group, a first tile group index value for the first tile group; determining a first size for the first tile group based on the first tile group index value and the size mapping; and decoding a number of coded tiles to form the decoded picture, the number of coded tiles being equal to the first size.
