CODING OF TRANSFORM COEFFICIENTS IN VIDEO CODING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18649901 titled 'CODING OF TRANSFORM COEFFICIENTS IN VIDEO CODING

The patent application describes methods and devices for video encoding, specifically focusing on the division of current pictures into coding units and determining various parameters for luma transform blocks within these units.

  • The device divides a current picture into one or more coding units.
  • It determines whether a luma transform block in a coding unit indicates an intra subpartition split type.
  • Based on this determination, the device assigns a luma block flag context index to the luma block flag of the current luma transform block.
  • The context index is determined either by the size of the current luma transform block or based on a variable from a previous luma transform unit in the coding unit.

Potential Applications: - Video streaming services - Video conferencing systems - Security surveillance systems

Problems Solved: - Efficient video encoding - Improved video quality - Reduced bandwidth consumption

Benefits: - Enhanced video compression - Higher quality video output - Reduced data usage for video transmission

Commercial Applications: Title: Advanced Video Encoding Technology for Enhanced Video Quality This technology can be utilized in various commercial applications such as online streaming services, video conferencing platforms, and security surveillance systems to improve video quality and reduce bandwidth consumption.

Prior Art: Prior art related to this technology may include existing video encoding methods and devices, as well as research on video compression techniques and algorithms.

Frequently Updated Research: Researchers in the field of video encoding and compression may be conducting studies on improving the efficiency and quality of video encoding algorithms, which could be relevant to this technology.

Questions about Video Encoding Technology: 1. How does this video encoding technology compare to existing methods in terms of efficiency and quality? 2. What are the potential implications of this technology for the future of video streaming and communication platforms?


Original Abstract Submitted

Methods and devices for video encoding are provided. In the method, the device divides a current picture into one or more coding units; determines, for a current luma transform block in a current coding unit of the one or more coding units, whether a first variable indicating an intra subpartition (ISP) split type equals ISP_NO_SPLIT. In response to determining the first variable equals ISP_NO_SPLIT, the device determines a luma block flag context index for a luma block flag of the current luma transform block as being equal to zero or one without determining whether the current luma transform block is smaller than the current coding unit. In response to determining the first variable does not equal ISP_NO_SPLIT, the device determines the luma block flag context index based on a second variable of a previous luma transform unit in the current coding unit.
