[0052]The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
[0053]In the video coding based on original quad-tree plus binary tree (QTBT) structure and the luma / chroma separate coding, the luma and chroma are coded separately for all Intra frames (for example, I-slice). However, in HEVC-SCC, the CPR is designed for three colour components joint. The MV of CPR is used for all three components. According to one aspect of the present invention, the CPR design is modified when the luma and chroma are coded separately. In this disclosure, various methods of CPR coding with the luma / chroma separate CU structure are proposed as follows. In the following, various aspects of using the CPR mode for luma / chroma separate coding are disclos...
