A method is described for presenting video signals from a first video source and one or more second video sources on a single touch screen display. The method includes: enabling display of primary content from a first video signal and secondary content from a second video signal on the touch screen display, using a display manager, in an adjacent or overlapping condition by scaling or shifting one of the first video signal(s) or the second video signal(s) to alter the size and to render the first video signal with the second video signal(s); and calculating a coordinate transformation, using a touch router device, on coordinates received from the touch screen display that correspond to the presentation at the touch screen display of the video signals and to accommodate any scaling or shifting performed on the first video signal(s) or the second video signal(s).
