  • the broadcast programme may e.g. be pub- lished as information in a newspaper or a weekly, as information on a teletext page, as information on a home page on the Internet, or in another form.
  • the recording equipment may be set as stated above. If several programmes or transmissions are to be recorded, the above-mentioned setting procedure must be followed for each transmission which is to be recorded. This involves a great risk that the user mixes up the various items of information and thereby sets the recording equipment wrongly.
  • a method of setting the video recorder by means of a connected television apparatus and a remote control comprises causing the video recorder to assume a programming state by means of a key on the remote control. Then the video recorder presents a menu or a form which may be filled by means of keys on the remote control.

Abstract

Cette invention se rapporte à un procédé de commande d'une unité de stockage (101, 205, 405) capable de stocker des transmissions sous la forme de signaux audio/vidéo transmis à partir d'un émetteur via un premier canal de communication (105) à des moments spécifiques, les informations, par exemple celles relatives aux heures de transmission, étant reçues via un second canal de communication électronique (105) pour l'identification des transmissions, ces informations étant mémorisées dans une mémoire (201). A cet effet, l'utilisateur sélectionne, au moyen d'une interface utilisateur électronique (501, 601), les transmissions qui doivent être mémorisées, et les heures des transmissions sélectionnées sont identifiées et utilisées pour commander l'unité de stockage (101, 205, 405). Ce procédé permet plus spécifiquement la commande automatique du moment auquel un magnétoscope vidéo doit passer en mode enregistrement. A cet effet, l'utilisateur indique les transmissions qu'il désire stocker sur un échéancier de programmes électronique (501, 601) et, grâce au procédé de cette invention, le magnétoscope vidéo enregistre les transmissions ainsi indiquées. Cette invention se rapporte également à un appareil de commande d'une unité de stockage (101, 205, 405).
