"The OnAir GT has multiple input connections to maximize its ability to bring you the best programming available. The first is the coaxial connector which allows you to scan for digital/analog over-the-air broadcasts from your local area using the included antenna, or you can connect the cable from your cable TV provider to view that programming. The second is the A/V in connector, which allows you to input not only S-video devices but virtually anything that has RCA outputs, such as DVD players, gaming consoles, and even that camcorder you just got for Christmas."
