ABSTRACT:
A digital signal processing system error-correction-decodes received or reproduced data, and compensates the error-correction-decoded data according to an amount of motion which is generated between sequential frames, in order to restore the received or reproduced data into an original video signal. The digital signal processing system includes an error concealment unit which outputs a video signal of a current frame if the decoded data is error-corrected data, and substitutes the current frame data at the current frame position with the previous frame data at the position corresponding to the amount of motion if the decoded data is data of an area where the error is not corrected, thereby providing a high quality picture without degradation.
