Abstract

A system and method for synchronizing two or more display elements of a multiple element display, is disclosed. The method includes embedding a frame count signal into the blanking portion of a video frame for each data stream received by the multiple display elements. Upon displaying the pixel data from a video frame, a frame count signal containing an identifying frame count is transmitted back to the computer. The computer compares the frame count signals to determine if the multiple display elements are synchronized. Upon a determination that the multiple display elements are not synchronized, the data stream for one or more display elements are adjusted accordingly. The system may be configurated as a federated system with two or more computers each communicatively coupled to each display element in a hierarchal system, where a secondary computer can control a display element if the primary computer or primary computer link fails.
