Title (EN) HOME ENTERTAINMENT SYSTEM AND METHOD OF ITS OPERATION
(FR) SYSTEME DE LOISIRS DOMESTIQUES ET PROCEDE DE FONCTIONNEMENT
Abstract:
(EN) An EPG database for a home entertainment system includes files that contain information about television programs retrievable by time and channel. The files are linked to each other so information about a future television program can be obtained by accessing a file about a current television program. A current television program displayed on the screen (20) of a home entertainment system includes an announcement or advertisement (56) of a future television program. The availability of an electronic program guide function (54) is signaled during, before, or after the announcement. A command is issued to invoke the EPG function (54). The information about the future television program is retrieved from the file about the current television program in the database. The EPG function (54) is executed with the retrieved information. The EPG function can be performed with respect to a future television program without embedding information about the future television program in the television signal.
(FR) L'invention concerne une base de données de type guide-programme électronique (EPG) pour système de loisirs domestiques, comprenant des fichiers renfermant des informations relatives aux émissions télévisées accessibles par heure et par chaîne. Les fichiers sont reliés les uns aux autres de manière que les informations relatives à une émission télévisée à venir peuvent être obtenues en accédant à un fichier portant sur une émission télévisée en cours. Une émission télévisée en cours affichée à l'écran (20) d'un système de loisirs domestiques comprend une annonce ou une publicité (56) relative à une émission télévisée à venir. La possibilité d'une fonction (54) guide-programme électronique (EPG) est signalée pendant, avant ou après l'annonce. Une commande est émise pour appeler la fonction EPG (54). Les informations relatives à une émission télévisée à venir sont récupérées à partir du fichier de la base de données portant sur les programmes en cours. La fonction EPG (54) est exécutée à l'aide des informations récupérées. Par conséquent, il est possible de réaliser une fonction EPG pour une émission télévisée à venir sans intégrer les informations relatives à l'émission télévisée à venir dans le signal de télévision.
