Abstract
In a decoding apparatus for decoding data, such as a digital video signal or the like, transmitted with a smaller number of bits than that of the original datum, sample data adjacent a sample datum to be decoded are separated from the transmitted data and compared with the sample datum to be decoded, whereupon a correcting datum is generated on the basis of the compared output. The original datum is recovered from the sample datum to be decoded and the correcting datum, whereby the quantizing error or distortion can be reduced without increasing the amount of encoded data.
