A decoding apparatus for receiving data transmitted from transmission equipment which performs subsampling so that a sampling phase is inverted between n frames (n is an integer), converts data subjected to the subsampling into a two-dimensional block structure, generates a discriminating code indicative of detected movement and performs compressing and encoding for the two-dimensional block data. The decoding apparatus comprises a decoding circuit for decoding data and for generating the decoded data, and an adaptive interpolation circuit for interpolating non-transmission data using the actually transmitted data. The interpolation circuit interpolates the non-transmission picture elements, adaptively using transmitted data of the identical frame and an adjacent frame responsively to the discriminating code.
