A display system comprises an interface circuit (706) for receiving various data from a network (704) to output to a downstream circuit system; a data separation circuit (708) to separate from data outputted from the interface circuit (706) still picture file and moving picture file concerning image and control data; an output control circuit (710) (control for still picture and control for moving picture) for a display controller (228), for example, in a unit of display component (14), on the basis of the control data from the data separation circuit (708); and a compressed file decoder circuit (712) installed upstream from an image data-processing circuit (224), for expanding the compressed file image to restore into still picture data and moving picture data.
