Abrégé
(EN)
The invention relates to a digital television decoder comprising - at least one first bi-directional interface with a display device intended to transmit and receive analogue data with the said display device, - at least one second mono-directional interface with the said display device intended to transmit analogue data to the said display device. According to the invention, the decoder comprises: - means to detect the reception of a video stream on the first interface, - means to switch the transmission of the data to the second interface when no video signal is received on the first interface.
(FR)
L'invention porte sur un décodeur de télévision numérique comprenant au moins une première interface bidirectionnelle pourvue d'un afficheur et destinée à émettre et recevoir des données analogiques par l'intermédiaire de l'afficheur, au moins une seconde interface unidirectionnelle pourvue de l'afficheur et destinée à transmettre des données analogiques à l'afficheur. Selon cette invention le décodeur comprend: un détecteur pour détecter la réception d'un flux vidéo sur la première interface; un commutateur pour commuter la transmission des données vers la seconde interface lorsqu'il n'y a pas de réception de signal vidéo sur la première interface.
