Title (EN) CABLE TELEVISION DECODER TO TELEVISION ACCESSORY INTERFACING
(FR) INTERFACE ENTRE UN DECODEUR DE TELEVISION PAR CABLE ET UN ACCESSOIRE DE TELEVISION
Abstract:
(EN) A system (10) interfaces a cable television decoder (12) to a VCR (14) incorporating a television scheduling system. The cable signal is supplied to the cable decoder (12) on cable (16) and the decoded output of the decoder (12) is supplied to the VCR (14) through cable (18) on a fixed channel. The CVR (14) receives commands from its remote controller (20). A cable decoder remote control emulator (22) is connected at (23) between the VCR (14) and the cable decoder (12). All channel selection codes supplied to the VCR (14) by its remote controller (20) are converted by the remote control emulator (22) to command codes recognized by the cable decoder (12). The remote control emulator (22) also suppresses execution of the channel selection codes suplied to the VCR (14), in order to keep the VCR (14) tuned to the fixed channel on which the decoded cable signal is supplied. The remote control emulator (22) drives an infrared emitter, which is positioned in front of an infrared input on the cable decoder (12). Thus, the remote control emulator (22) replaces the conventional cable decoder remote controller. The user communicates with the system using the VCR remote controller (20). For the user, the system (10) appears to function in the same manner as would the VCR (14) connected to the TV (19) with no cable decoder (12) present.
(FR) Un système (10) assure l'interface entre un décodeur (12) de télévision par câble et un magnétoscope (14) comprenant un système de programmation de télévision. Le signal du câble est acheminé au décodeur (12) du câble, situé sur le câble (16), et la sortie décodée du décodeur (12) est acheminée au magnétoscope (14) par l'intermédiaire du câble (18), sur un canal fixe. Le magnétoscope (14) reçoit des instructions de sa télécommande (20). Un émulateur (22) de télécommande du décodeur du câble est connecté en (23), entre le magnétoscope (14) et le décodeur (12) du câble. Tous les codes de sélection de canaux transmis au magnétoscope (14) par sa télécommande (20), sont transformés par l'émulateur (22) de télécommande en des codes d'instructions reconnus par le décodeur (12) du câble. L'émulateur (22) de télécommande supprime également l'exécution des codes de sélection de canaux transmis au magnétoscope (14), afin de maintenir le magnétoscope (14) syntonisé sur le canal fixe, dans lequel le signal du câble décodé est transmis. L'émulateur (22) de télécommande excite un émetteur infra-rouge, lequel est positionné devant une entrée infra-rouge se trouvant dans le décodeur (12) du câble. Ainsi, l'émulateur (22) de télécommande remplace la télécommande du décodeur de câble classique. L'utilisateur communique avec le système à l'aide de la télécommande (20) du magnétoscope. Pour l'utilisateur, le système (10) semble fonctionner comme le magnétoscope (14) connecté au téléviseur (19), sans décodeur (12) de câble.
