Abstract
PURPOSE: To remove unnecessary information, by the coding using the identification information and the color information, in coding the color diagram consisting of the same color for the entire lines.
CONSTITUTION: The color video information CLS is set to the register 1. The color video information preceding by one is set to the register 2. The output of the both registers is inputted to the comparator 4 and the content of the both registers is compared. If there is any change in the content, each color video information is coded in the form of the color signal continued length RL + color information CL. If there is no change in the content, the color video information is compressed by coding with the format of the identification signal for no change + color information CL. Especially, when this is applied to monotonous color picture, the reproduction of color picture is made possible with less amount of information.
