ABSTRACT:
This invention relates to an apparatus for an efficient coding which reduces the number of bits per one pixel of digital television signals. The pixel data in the present field is predicted by way of a linear combination of the pixel data in the past several fields and parameters as prediction coefficients, and the parameters which make this prediction difference minimum are derived, and this parameter is transmitted.
