IMAGE DECODING METHOD FOR RESIDUAL CODING IN IMAGE CODING SYSTEM, AND APPARATUS THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17801714 titled 'IMAGE DECODING METHOD FOR RESIDUAL CODING IN IMAGE CODING SYSTEM, AND APPARATUS THEREFOR
Simplified Explanation
The patent application describes an image decoding method performed by a decoding apparatus. Here is a simplified explanation of the abstract:
- The method involves obtaining a flag that indicates whether transform skip is available.
- Based on the transform skip flag, another flag called TSRC available flag is obtained.
- The TSRC available flag determines the residual coding syntax for a current block.
- Residual information of the determined residual coding syntax is obtained.
- A residual sample of the current block is derived using the residual information.
- Finally, a reconstructed picture is generated based on the residual sample.
Potential applications of this technology:
- Image and video decoding in various devices such as smartphones, tablets, and televisions.
- Multimedia streaming services that require efficient image decoding.
Problems solved by this technology:
- Efficient decoding of images and videos by utilizing transform skip and TSRC techniques.
- Reducing the computational complexity and memory requirements of image decoding algorithms.
Benefits of this technology:
- Improved image and video decoding performance.
- Reduced power consumption and improved battery life in portable devices.
- Enhanced user experience with faster and smoother multimedia playback.
Original Abstract Submitted
An image decoding method performed by a decoding apparatus, according to the present document, comprises the steps of: obtaining a transform skip available flag; obtaining a TSRC available flag, on the basis of the transform skip available flag; determining a residual coding syntax for a current block, on the basis of the TSRC available flag; obtaining residual information of the determined residual coding syntax for the current block; deriving a residual sample of the current block, on the basis of the residual information; and generating a reconstructed picture, on the basis of the residual sample, wherein the transform skip available flag is a flag regarding whether transform skip is available, the TSRC available flag is a flag regarding whether TSRC is available, and the TSRC available flag is obtained on the basis of the transform skip available flag having a value of 1.
