Abstract
(EN)
Multiple channel maps are embedded in a television transmission and the appropriate channel map (68) corresponding to the particular television service used by the viewer is downloaded for use with the television receiver. Each channel map (68) is accompanied by a channel map identifier (66) which identifies the source of the television transmission and a geographic identifier. The source of a television transmission is automatically detected by monitoring the radio-frequency spectrum allocations of telecast stations. The geographic area identifier is determined by comparison with a user inputted geographic area identifier. The channel map (68) having a channel map identifier (66) corresponding to the detected television transmission source and the user inputted geographic area identifier is downloaded and stored for future use.

Des cartes d'attribution de canaux multiples sont intégrées à un signal d'émission télévision et la carte appropriée (68), correspondant à une émission télévision donnée utilisée par le télespectateur, est téléchargée pour être utilisée sur le récepteur de télévision. Chaque carte de canal (68) est accompagnée d'un identificateur de carte de canal (66), qui identifie la source d'émission de télévision, et d'un identificateur géographique. La source d'une émission de télévision est automatiquement détectée par observation des attributions dans le spectre des radio-fréquences des stations de télévision. L'identificateur de zone géographique est déterminé par comparaison avec un identificateur de zone géographique introduit par l'utilisateur. La carte de canal (68) comportant un identificateur de carte de canal (66) qui correspond à la source d'émission de télévision détectée et à l'identificateur de zone géographique introduite par l'utilisateur est téléchargée puis mémorisée pour utilisation ultérieure.
