Abstract
A difference between an original digital value of a picture element to be encoded and an original digital value of a spatially adjacent picture element of the picture element is determined by a detecting circuit. The video data of the spatially adjacent picture element is decoded to generate a decoded value by a local decoder. A compressed encoded video data of the picture is generated wherein a difference between a decoded value of the compressed encoded video data and the decoded value is closest to the difference.
