A system and methods perform an automatic TV signal/tuner setup in a tuner device (e.g., a PC, a personal video recorder, a set-top box, etc.) that has one or more tuners. The setup identifies the number of tuners in the device, whether the tuners are analog or digital, and what broadcast standard each tuner supports. The geographic region in which the device will be receiving TV signals is identified, and tuners supporting that region are identified. Digital tuners are reported as being digital, while analog tuners are scanned to locate valid TV signals, and to determine the source of any valid TV signals (e.g., an antenna, a cable provider, a set-top box). |
