Movement compensation error correction system

Abstract

Abstract PURPOSE:To obtain a reproduced picture with excellent quality by using an estimate moving vector so as to extract a picture element block, replacing the block into other picture element block so as to correct the transmission error. CONSTITUTION:Address information ad1 of a picture element block affected by a transmission error is inputted to a delay circuit 1 for one block line delay and retarded address information ad2 is inputted to an address generating circuit 2, from which an address ad3 of a surrounding picture element block is generated and when the production of all addresses is finished, a timing signal tm1 is outputted. Then the information ad3 is inputted to a moving vector memory 3, revised by a moving vector mv1 from a moving vector decoder and the extracted moving vector my2 is sequentially inputted to a moving vector estimate circuit 4. When the signal tm1 is inputted, an estimate vector mv3 is outputted and fed to a frame memory 5, a picture element block signal cd is outputted, which is used for error correction.
