ABSTRACT:
In an image decoder of MPEG system or the like, a delay buffer which is able to store data which corresponds to at least one frame is provided in the rear stage of an input buffer which is normally provided, and a frame synchronizing pulse is applied to determine the timing of display independently of that which is determined by the bit stream. In synchronization with the frame synchronizing pulse which occurs for the first time after the passage of a delay period set for every frame in each of the bit streams, that frame is displayed. The input bit streams coming in during the period of time which elapses from the passage of the delay period until the occurrence of the frame synchronizing pulse, are absorbed by the delay buffer.
