Dekodierung eines komprimierten digitalen Bildsignals

摘要

A compressed information stream includes predicted pixel blocks. The predicted pixel blocks are associated with one or more scaled reference pixel blocks via respective scaled motion vector information. A method for adapting a first resolution of a scaled reference pixel block to a second resolution of said scaled motion vector information comprises the step of filtering, using a discrete cosine transform (DCT) filter, said scaled reference pixel block. The method is used in a decoder. <IMAGE>
