Abstract
Abstract An image information transmission system comprises a plurality of image information processing units for processing image information, an image information transmission line and a control information transmission line independent from the image information transmission line for transmitting control information related to the processing of the image information processing units. The control information can be transmitted even during the transmission of the image information.
