SIGNALING METHOD FOR CHROMA INTRA PREDICTION MODE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18651337 titled 'SIGNALING METHOD FOR CHROMA INTRA PREDICTION MODE
The abstract describes a method of video decoding that involves selecting an entropy decoding context based on the usage of a chroma-from-luma (CfL) mode in neighboring chroma blocks. The method includes decoding a flag from the video bitstream to determine if the CfL mode is enabled for the current chroma block.
- The method involves receiving a video bitstream with multiple blocks, including a current chroma block.
- A context is selected for entropy decoding based on the usage of the CfL mode in neighboring chroma blocks.
- The flag is decoded to determine if the CfL mode is enabled for the current chroma block.
- The current chroma block is decoded according to the value of the flag.

Original Abstract Submitted
An example method of video decoding includes receiving a video bitstream that comprises a plurality of blocks including a current chroma block. When less than a threshold number of neighboring chroma blocks of a current chroma block use a chroma-from-luma (CfL) mode, a first context is selected as an entropy decoding context for a first flag. When at least the threshold number of neighboring chroma blocks use the CfL mode, a second context is selected as the entropy decoding context for the first flag. The method also includes entropy decoding the first flag from the video bitstream using the entropy decoding context, where the first flag indicates whether the CfL mode is enabled for the current chroma block, and decoding the current chroma block according to a value of the first flag.
