<p>Video signal decoding circuit provided with means for detecting errors in a portion of a video signal and means for substituting 410,411,420,421 for said error containing portion a similar portion of a preceding image frame in accordance with motion vector data, is further provided with spatial filtering means 480 for reducing block artifacts generated by the substitution. The video signal is encoded using an error correcting code according to a two dimensional redundancy reduction encoding system such as an interframe differentially encoding system.</p> |
