Title
(EN) SIGNAL INPUT SELECTOR FOR TELEVISION SET AND METHOD OF IMPLEMENTING SAME
(FR) SELECTEUR DE L'ENTREE DE SIGNAUX POUR POSTE DE TELEVISION ET PROCEDE DE MISE EN OEUVRE CORRESPONDANT
Abstract
(EN)
Management of various audiovisual signal inputs to an entertainment system that includes a television receiver can be performed by a circuit in which a selector swith (100) cyclically monitors the incoming signal inputs with video (101) and audio (102) signal detectors to register which inputs receive active signals. Selector switches (104, 105) for connecting an incoming audio signal and video signal to the television receiver are controlled by a central processing unit (103) in response to the output of the detectors (101, 102) monitoring for active signal sources. Consequently, a user operating a user interface (7) can most efficiently monitor and select active video and audio signal sources for use by the television set.

On effectue la gestion de diverses entrées de signaux audiovisuels dans un système de divertissement qui comprend un récepteur de télévision au moyen d'un circuit dans lequel un commutateur de sélecteur (100) surveille cycliquement les entrées de signaux avec les détecteurs de signaux vidéo (101) et audio (102) à enregistrer, ces entrées recevant les signaux actifs. Les commutateurs des sélecteurs (104, 105) destinés à connecter un signal audio et un signal vidéo entrants au récepteur de télévision sont pilotés par une unité centrale (103) en réponse à la surveillance par les détecteurs (101, 102) des sources de signaux actifs; par conséquent, un utilisateur manipulant une interface utilisateur (7) peut surveiller et sélectionner avec un maximum d'efficacité les sources de signaux actifs audio et vidéo utilisés par le poste de télévision.
