Patent

CA 1334691

A decoding apparatus decodes data, such as a digital video signal or the like transmitted from a coding (transmission) apparatus for coding an original datum with a less number of bits than that of the original datum. Adjacent sample data of a sample datum to be decoded are separated from the transmitted data. These data are compared with the sample datum to be decoded and the correcting datum is generated based on the compared output. The original datum is recovered from the sample datum to be decoded and the correcting datum, thereby the quantizing error or distortion can be reduced without increasing the encoding data amount.
