摘要：
A method and apparatus for encoding/decoding a video signal according to an MCTF coding scheme is provided. Not only pictures, which are to be converted into L pictures, but also pictures, which are to be converted into H pictures, at the current temporal decomposition level are used as candidates for a reference picture for coding a current picture into a predictive image. A previous picture, which has already been converted into an H picture, can also be used as a reference picture for converting the current picture into an H picture. Using the previous picture as the reference picture increases MCTF coding efficiency if the previous picture has an image most highly correlated with that of the current picture.
