This paper proposes a novel coding method that reduces correlation of 4:4:4 chroma format in high-resolution images more than HDTV. The proposed method compensates for Intra prediction errors by applying the linear prediction to a certain Intra prediction error. The adaptive inter-channel prediction uses a coefficient that minimizes the MSE of the Intra prediction errors in each channel. The experimental results show that combining the Intra prediction and inter-channel prediction has better coding efficiency than the conventional method.
