TECHNIQUES FOR SUBSAMPLING FOR CROSS COMPONENT PREDICTION IN VIDEO CODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240129458 titled 'TECHNIQUES FOR SUBSAMPLING FOR CROSS COMPONENT PREDICTION IN VIDEO CODING
Simplified Explanation
The patent application describes a method for coding video data by subsampling chroma samples relative to luma samples, determining a subsampling technique for luma samples for cross-component prediction, and coding the video data using the chosen subsampling technique and prediction mode.
- Explanation of the patent:
- Receiving a block of video data with subsampled chroma samples compared to luma samples.
- Determining a subsampling technique for luma samples for cross-component prediction.
- Coding the video data using the selected subsampling technique and prediction mode.

Original Abstract Submitted
a method coding video data includes receiving a block of video data, wherein chroma samples of the block of video data are subsampled relative to luma samples of the block of video data (e.g., 4:2:0 or 4:2:2 video content). a video coder may determine a subsampling technique, from a plurality of subsampling techniques, for the luma samples of the block of video data for a cross-component prediction mode, and may code the block of video data using the subsampling technique and the cross-component prediction mode. a first subsampling technique of the plurality of subsampling techniques includes not applying subsampling to the luma samples of the block of video data, and a second subsampling technique of the plurality of subsampling techniques includes a combination of downsampling filters to be applied to the luma samples of the block.
