Abstract: A method includes determining whether to switch from a first input video signal to a second input video signal. Upon switching from a first input video signal to a second input video signal, determining whether the current displayed frame has terminated. If the current displayed frame has terminated, process the second video input signal and load data corresponding to the second video input signal from the timing generator, scale and pixel clock registers correspondingly into the timing generator, scaler and pixel clock. Generate a clock signal for the second input video signal. Calculate generator parameter(s) corresponding to the second input video signal. Generate timing control signals for the second input video signal. Determine if a new frame of the second input video signal has occurred. Provide timing control signals and pixel data for the video to be displayed and corresponding the second input video signal.
