VIDEO ENCODING AND DECODING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240323372 titled 'VIDEO ENCODING AND DECODING

The abstract describes a patent application for a decoder that can decode a picture from a bitstream where the picture is divided into multiple tile groups. The decoder decodes the bitstream in two parts, first decoding parameter set data to create a size mapping for the tile groups, and then decoding the coded tile groups based on the size mapping.

Decoder configured to decode pictures from bitstreams with partitioned tile groups
Decoding first part of bitstream to create size mapping for tile groups
Decoding second part of bitstream to decode coded tile groups based on size mapping
Determining tile group size from tile group index value and size mapping
Decoding number of coded tiles to form the decoded picture

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

Problems Solved: - Efficient decoding of pictures from partitioned tile groups - Improved data compression and transmission in multimedia applications

Benefits: - Enhanced picture quality - Reduced bandwidth usage - Faster decoding process

Commercial Applications: Title: Advanced Video Decoding Technology for Multimedia Applications Description: This technology can be used in video streaming services, video conferencing platforms, and digital media players to enhance picture quality and optimize bandwidth usage.

Questions about the technology: 1. How does this decoder improve the efficiency of decoding pictures from partitioned tile groups? 2. What are the potential applications of this technology in the multimedia industry?

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.
