Abstract
A system for overlaying a motion video signal onto an analog signal on a display. The system includes a motion video processing unit for receiving and processing the motion video signal into a signal having an analog video format, a video format analyzer and synchronizer device for receiving the analog signal and for determining video timing parameters and a corresponding original pixel clock of the analog signal and for controlling video timing parameters of the motion video signal to match the video timing parameters of the analog signal determined by the video format analyzer and synchronizer device so as to provide an output motion video signal which is synchronized with the analog signal and a display determining device for determining the display of the analog output signal or the synchronized output motion video signal on the display. The video format analyzer and synchronizer device includes a video format analyzer for determining horizontal and vertical video timing parameters of the analog signal, including vertical and horizontal sync times, active video time and vertical phase of the analog signal, a clock signal unit for receiving components of the analog signal and pr…
