Abstract
An image transmission system in which when each of a plurality of image signals is transformed into compressed image data compressed at an image compressing portion, the image data are assembled to cells at a cell assembly portion, and the cells from the cell assembly portion are switched at a switching portion, a band controller controls the cell assembly portion so that a band of a transmission line has a value lower than a total band required for a simultaneous transmission of each of the image data. Also, a network controller for controlling band controllers or compression rate controllers at each of communication nodes on a network is provided. Moreover, a sensor which detects a change of an event to control the band controller or the compression rate controller is provided.
