  • Patent number: 8384707
    Abstract: An image display system synchronizes the display of images on a plurality of display devices. The method entails generating at a first computer system a first signal representing first image data to be displayed on a first display device, generating at a second computer system a second signal representing second image data to be displayed on a second display device, and a method for synchronizing the first and second image data. The synchronizing method includes using 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.

  • Patent number: 5455627
    Abstract: A programmable video output format (VOF) generator that enables a processing system to drive different video display devices with varying video format requirements. The programmable VOF generator includes a compiler that generates video formats based on user input, and a state machine that generates all video signals with requisite output format. The compiler allows the user to provide minimal information on general display parameters using a high-level language. Therefore, no specialized knowledge of the video display hardware requirements is required from the user.
