Title: METHOD AND APPARATUS FOR INTRA CHROMA CODING IN IMAGE AND VIDEO CODING
Abstract:
A method and apparatus for chroma Intra prediction are disclosed. According to one method, a chroma Intra mode set comprising more than six chroma Intra coding modes are generated and chroma Intra-prediction encoding or decoding is applied to the current chroma block using a current chroma Intra mode selected from the chroma Intra mode set. According to another method, a chroma MPM list is determined and a current chroma Intra mode is signaled using chroma MPM process at the video encoding system or parsing the current chroma Intra mode using the chroma MPM process at the video decoding system, where the chroma MPM process comprises using a chroma MPM flag to indicate whether the current chroma Intra mode belongs to the chroma MPM list.
