摘要：
A video coding method which enables reduction in the decrease in the efficiency of coding a video and enhancement of the image quality of the resulting decoded video involves: predicting a video signal to generate a prediction signal (S100); calculating, as a prediction error signal, the difference between the video signal and a prediction signal (S110); generating a reconstructed video signal by reconstructing the video signal based on the prediction signal and the prediction error signal (S120); determining filter data items that are used to filter each of at lest two of the prediction signal, the prediction error signal, and the reconstructed video signal (S130); and coding the determined filter data items based on the cross correlations between the determined filter data items.
