TECHNIQUES FOR SUBSAMPLING FOR CROSS COMPONENT PREDICTION IN VIDEO CODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18483891 titled 'TECHNIQUES FOR SUBSAMPLING FOR CROSS COMPONENT PREDICTION IN VIDEO CODING
Simplified Explanation
The patent application describes a method for coding video data that involves subsampling chroma samples relative to luma samples in a block of video data. The video coder selects a subsampling technique for the luma samples for a cross-component prediction mode and codes the block of video data using the chosen subsampling technique and prediction mode.
- The method involves subsampling chroma samples of video data relative to luma samples
- The video coder selects a subsampling technique for luma samples for cross-component prediction
- Two subsampling techniques are described: one without subsampling luma samples and one with downsampling filters applied to luma samples
Potential Applications
This technology could be applied in video coding and compression algorithms to improve efficiency and reduce data size.
Problems Solved
This technology helps in optimizing video coding by selecting appropriate subsampling techniques for different components of video data.
Benefits
The benefits of this technology include improved video coding efficiency, reduced data size, and potentially better video quality.
Potential Commercial Applications
This technology could be used in video streaming services, video conferencing applications, surveillance systems, and any other application that involves video data processing.
Possible Prior Art
One possible prior art could be the use of different subsampling techniques in video coding algorithms to improve compression efficiency.
What are the specific subsampling techniques used in this method?
The specific subsampling techniques used in this method are a first technique that does not apply subsampling to luma samples and a second technique that involves a combination of downsampling filters applied to luma samples.
How does the video coder determine the subsampling technique for the luma samples?
The video coder determines the subsampling technique for the luma samples based on a cross-component prediction mode, selecting from a plurality of subsampling techniques available.
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.
