INTRA CHROMA MODE LIST CONSTRUCTION FOR VIDEO CODING - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18187517 Titled 'INTRA CHROMA MODE LIST CONSTRUCTION FOR VIDEO CODING'
Simplified Explanation
This abstract describes a method for encoding or decoding video data. The method involves creating a list of different ways to predict the color information (chroma) in a specific block of the video. These prediction modes are derived from the prediction modes of neighboring blocks that have the same brightness information (luma). The method then determines the best prediction mode for the chroma block from the list and uses it to encode or decode the chroma block.
Original Abstract Submitted
A method of encoding or decoding video data includes constructing a list of chroma intra-prediction modes for a chroma block of a current block of the video data, wherein constructing includes adding intra-prediction modes of a first group to the list of chroma intra-prediction modes, the first group comprising two or more intra-prediction modes derived from intra-prediction modes of two or more co-located luma blocks of the current block that are co-located with the chroma block; determining an intra-prediction mode for the chroma block from the list of chroma intra-prediction modes; and encoding or decoding the chroma block based on the intra-prediction mode.
