Inter Cross-Component Prediction Merge Mode for Video Coding beyond VVC

As an incubator of next generation video coding techniques beyond versatile video coding (VVC) capability, enhanced compression model (ECM) has been initiated by the Joint Video Exploration Team (JVET). This paper presents an Inter CCP merge mode to improve the coding performance for chroma inter coding. Experimental results show that Inter CCP merge mode provides an average Bjontegaard delta rate (BD-rate) change of 0.01%/-0.69%/-0.76% and -0.03%/-2.31%/-2.38% on Y/Cb/Cr components, respectively, compared with ECM-10.0 in RA/LDB configurations under the common test condition, with a negligible running time change.
