Abstract

A computer convergence system includes a convergence functionality module, a computer, and a display device. The convergence functionality module includes a first input for receiving a first video signal and a second input for receiving a second video signal. The computer is coupled to the convergence functionality module and receives therefrom indications of the first video signal received at the first input port and indications of said second video signal received at the second input port. The computer includes a controller for controlling the mapping of the indications of the first video signal to the primary video viewing surface, and further controls the mapping of the indications of the second video signal to either the second video viewing surface or the data acquisition destination.
