摘要：In a method of video coding, in which a difference is formed between inputpicture values and picture prediction values and that difference is transforming with aDCT, the picture prediction is formed as: P=(1−c)P+CPwhere Pis a closed loop predictor

which is restricted to prediction values capable of exact reconstruction in a downstreamdecoder and Pis a spatial predictor which is not restricted to prediction values capable ofexact reconstruction. The factor can vary from zero to unity depending on a variety ofparameters.
