VIDEO CODING WITH REFERENCE FRAMES OF HIGH RESOLUTION

摘要

The invention provides an encoder (1) for encoding a video signal comprising video frames each consisting of image blocks, wherein said encoder (1) comprises a processing unit (4) which calculates at least one high resolution reference image block on the basis of previously encoded image blocks by executing a super resolution algorithm (SRA) to perform a local motion compensation; and a motion compensation unit (5) which calculates on the basis of the calculated high resolution reference image block a temporal predictor (TP) which is subtracted from a current image block of said video signal. Further, a corresponding decoder (16) is provided.
