ABSTRACT:
A method for transmission of variable length code words is provided in which the variable length code words are allocated into a data storage field not only from the front end of the same but also from the rear end, whereby unwanted affection by transmission error will be minimized. A coding apparatus produces coded data of such a format that after different type video signals are divided into a common signal area and a not-common signal area, the coded data of the common signal area is allocated into one data storage field in a sequence from the front end of the same and the coded data of the not-common signal area is allocated in a reverse sequence from the rear end. Accordingly, such different video signals can successfully be decoded with a decoder designed for processing one particular video signal.
