Abstract
A method of converting a digital video signal including first words each being composed of N.sub.1 bits into a digital video signal which consists of second words each being composed of N.sub.2 bits (N.sub.2 <N.sub.1) by separating each of the first words into a first portion which consists of the N.sub.2 bits including a most significant bit and a second portion which consists of the remaining (N.sub.1 -N.sub.2) bits including a least significant bit, and storing the first portions of the first words and the second portions. Third words each of which consists of N.sub.2 bits are then composed by sequentially arranging the second portions. A first group of words which represent converted digital image signal are composed by first portions, and a second group of words are composed by sequentially linking the third words. Each scanning line of a converted digital video signal is then composed by the second group of words sequentially arranged before or after the first group of words.
