Abstract

In an encoding circuit for a digital video signal, a digital video signal is subjected to given orthogonal transform to be converted into corresponding conversion data. Components of the conversion data are scanned in a given order to generate a main data sequence from the conversion data. The main data sequence is separated into at least two sub data sequences. A first of the two sub data sequences is encoded into corresponding words of a given variable-length code. A second of the two sub data sequences is encoded into corresponding words of the variable-length code.
