DEVICE JOINTLY IMPLEMENTING POST-PROCESSING AND DECODING OF DATA

摘要

PURPOSE: A device jointly implementing a post-processing and a decoding of data is provided to process coded data blocks included in a sequence of digital images according to the block-based coding. CONSTITUTION: A device jointly implementing a post-processing and a decoding of data comprises a post-processing circuit DFD(33). Such a device effectively corrects the blocking artifacts while minimizing the bandwidth used, the decoder directly transmitting decoded data blocks(B) to the post-processing circuit. In addition, such a device introduces no or little drift during the decoding since the decoder continues to use reference images(RB) during a motion compensation step. The reference images are no longer the decoded images but the completely processed image as the post-processing circuit is located in the decoding loop.
