Intra-Prediction Using a Cross-Component Linear Model in Video Coding - A simplified explanation of the abstract
This abstract first appeared for US patent application 18544099 titled 'Intra-Prediction Using a Cross-Component Linear Model in Video Coding
The patent application describes a video coding mechanism that involves encoding prediction information for chroma samples based on down-sampled neighboring luma samples.
- The mechanism receives a video signal partitioned into a chroma block and a first neighboring luma block.
- Prediction information for chroma samples is encoded into a bitstream using intra-prediction.
- The prediction information is determined based on down-sampled neighboring luma samples generated from a single row of luma samples.
- The bitstream containing the prediction information is transmitted for decoding and display of the chroma samples.
Potential Applications: - Video compression technology - Multimedia streaming services - Video conferencing systems
Problems Solved: - Efficient encoding of chroma samples in video signals - Reduction of data transmission bandwidth - Improved video quality during decoding
Benefits: - Enhanced video compression efficiency - Reduced data storage requirements - Improved video streaming performance
Commercial Applications: Title: Advanced Video Compression Technology for Enhanced Streaming Services This technology can be utilized in various commercial applications such as online video platforms, video conferencing services, and digital television broadcasting to improve video quality and reduce bandwidth requirements.

2. What are the potential benefits of using this video coding mechanism in multimedia streaming services? - The benefits include improved video compression efficiency, reduced data storage requirements, and enhanced video streaming performance.
Original Abstract Submitted
A video coding mechanism is disclosed. The mechanism includes receiving a video signal partitioned into a chroma block and a first neighboring luma block. The mechanism also includes encoding prediction information for chroma samples of the chroma block into a bitstream. The prediction information for the chroma samples is determined via intra-prediction based on down-sampled neighboring luma samples. The down-sampled neighboring luma samples are generated from a single row of luma samples from the first neighboring luma block. A bitstream including the prediction information for the chroma samples is transmitted to support decoding and display of the chroma samples.
