Abstract
Each of image information playback units () detects that image display has started, on the basis of a change in digital video data (VDa, VDb), and generates a frame number (FNa, FNb) (). One of the image information playback units () combines frame signals that output frame synchronization signals (FSa) (). The other image information playback unit () separates the frame synchronization signals (FSa) and generates a frame number (SFNa) (). The generated frame number (SFNa) and the frame number (FNb) generated in the second image information playback unit () are compared, and on the basis of the comparison results the frequency of the decoding reference clock signal is controlled (). When images are displayed by a plurality of display units () connected to the image information playback units (), the images can be synchronized with a simple structure.
