A system for processing multiple signals. The system includes a receiver for receiving a video signal representative of a camera image, the video signal being represented as multiple horizontal lines in a video frame, a receiver for receiving multiple analog signals, the analog signals being representative of different analog inputs, a buffer for digitally double buffering at least some of the analog signals, wherein the buffer effects repetition of analog signals within a single video image frame, repeats sampling of the analog signals more than once within a single video frame and the digitization enhances recovery of the signal resolution of the analog signal with greater frequency and representation than an analog signal on a video signal. The system also comprises a mixer for mixing the analog signals with the video signal whereby the analog signals are contained on at least some of the horizontal lines of the video frame, and an output for outputting the mixed analog and video signals. |
