CA 2509672

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).

L'invention concerne un système et des procédés permettant d'effectuer un réglage automatique signal TV/tuner dans un dispositif tuner (p.ex., un ordinateur personnel, un magnétoscope personnel, un boîtier décodeur etc.) qui possède au moins un tuner. L'installation identifie le nombre de tuners du dispositif, si les tuners sont analogiques ou numériques, et quelle est la norme de radiodiffusion de chaque tuner. La zone géographique dans laquelle le dispositif va recevoir les signaux TV est identifiée, les tuners supportant cette zone sont identifiés. Des tuneurs numériques sont signalés comme étant numériques tandis que les tuners analogiques sont scannés pour localiser les signaux TV valides et pour déterminer la source de n'importe quels signaux TV valides (p.ex., une antenne, un fournisseur de câble, un boîtier décodeur).
