摘要：
An image display system synchronizes the display of images on a plurality of display devices. The system includes a first computer system generating a first signal representing first image data to be displayed on a first display device, a second computer system generating a second signal representing second image data to be displayed on a second display device, and means for synchronizing the first and second image data. The synchronizing means includes a phase-locked loop circuit having a digital rate controller. The digital rate controller allows programmable control of the speed of the phase-locked loop.
