Abstract
A method for reprogramming a video input device to multiplex video data from at least two different video sources is disclosed. A video input device contains control registers for controlling the behavior of the video input device. At least first video data from a first source and a second video data from a second source are received at the video input device. Information about the video data is sent to a controller which generates reprogramming data based on the information. The reprogramming data is transmitted to the video input device, wherein the reprogramming data reprograms the operation of the control registers. Portions of the first and second video data are outputted based upon how the control registers are reprogrammed.
