Abstract
A data processor includes a first encoder, a first storage medium, a subtracter, a second encoder, a second storage medium, and an output section. The first encoder generates, by using a predetermined first coding method, a main code prepared by encoding a moving picture signal input as an original signal. The first storage medium stores the main code generated by the first encoder. The subtracter calculates a coding distortion generated upon coding by the first encoder. The second encoder encodes, by using a predetermined second coding method, the coding distortion calculated by the subtracter, thereby generating a compensation code. The second storage medium stores the compensation code generated by the second encoder. The output section outputs the main and compensation codes respectively stored in the first and second storage media.
