Abstract
In one embodiment, a method for synchronizing a plurality of video signals received from one or more video sources is provided. The method includes providing one or more video sources and providing a codec including an internal reference oscillator. The method also includes generating a plurality of horizontal and vertical synchronization pulses based on the reference frequency of the internal reference oscillator, generating a composite synchronization pulse based on the plurality of horizontal and vertical synchronization pulses, and transmitting the composite synchronization pulse to the one or more video sources via a communication link. The method further includes separating the composite synchronization pulse back into the plurality of horizontal and vertical synchronization pulses, generating a pixel clock signal for the one or more video sources based on one or more of the plurality of horizontal and vertical synchronization pulses, and genlocking the one or more video sources based on the generated clock signal.
