Abstract
A picture signal transmission system for transmitting after coding a picture signal obtained by scanning at least one picture to be transmitted, in which a difference between a representative level value of each picture element unit formed by at least one picture element and a forecast value obtained in accordance with a predetermined rule and based on a representative level value of adjacent ones of said picture element units is detected, and in which first level information and second level information are transmitted. The first level information indicates, for each picture element by a bit of binary information, whether or not the difference exceeds a predetermined threshold value for a group of picture elements corresponding to a predetermined area of the picture. The second level information indicates level information of particular picture elements on each of which said difference exceeds the threshold value.
