In a data encoding process: data is encoded by using unit bit series obtained from an encoding bit series; the encoding bit series is searched for a first bit series identical to a portion of the encoded data; the portion is substituted with a second bit series which includes a leading code indicating a leading position of a substitution range and position information indicating the position of the first bit series in the encoding bit series. In a data decoding process: the position information is detected from the substitution range in received data after the leading code is detected in the data; a substitution bit series is extracted from the position in the encoding bit series indicated by the position information; and the data in the substitution range is substituted with the substitution bit series so as to restore the encoded data.
