Abstract
In a method of video coding, in which a difference is formed between input picture values and picture prediction values and that difference is transforming with a DCT, 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 downstream decoder and Pis a spatial predictor which is not restricted to prediction values capable of exact reconstruction. The factor can vary from zero to unity depending on a variety of parameters.
