Video Multiplexer for connecting and synchronizing two videocameras to the same frame grabber

Our proprietary special electronics board (Mpx) was developed to concurrently capture the signal from two synchronized cameras. This board is based on the fact that we can multiplex two separate video signals in only one, by switching between the two video signals at the field rate (50 Hz). In this way we obtain a new interlaced signal in which odds and even fields contain the two different signals. We can then acquire the signal using an ordinary full frame single channel acquisition board. At this point, we have in the frame memory buffer the two original signals, just missing half vertical resolution and halving the temporal resolution.
