Title (EN) METHOD AND APPARATUS FOR PROVIDING DUAL AUTOMATIC GAIN CONTROL DELAY SETTINGS IN A TELEVISION RECEIVER
(FR) PROCEDE ET DISPOSITIF PERMETTANT UN DOUBLE REGLAGE DE RETARD DE COMMANDE AUTOMATIQUE DE GAIN DANS UN TELEVISEUR
Abstract: front page image
(EN)The present invention provides a method and apparatus for processing a received television signal comprising one of a first type of television signal and a second type of television signal. Specifically, the method comprises amplifying said received television signal in response to a control signal. If the received television signal comprises the first type of television signal, the RF amplifier gain is reduced when said received television signal exceeds a first signal level. If the received television signal comprises the second type of television signal, the RF amplifier gain is reduced when said received television signal exceeds a second signal level. The second signal level is greater than said first signal level. A concomitant apparatus is also provided. As the first signal level is lower for the first type of television signal, reception of the first type of television signal is improved.
(FR)La présente invention concerne un procédé et un dispositif permettant de traiter un signal de télévision reçu comprenant un premier type de signal de télévision et un second type de signal de télévision. Plus particulièrement, le procédé consiste à amplifier le signal de télévision reçu en réaction à un signal de commande. Si le signal de télévision comprend le premier type de signal de télévision, le gain d'un amplificateur RF est réduit lorsque le signal de télévision reçu est supérieur à un premier niveau de signal. Si le signal de télévision comprend le second type de signal de télévision, le gain de l'amplificateur est réduit lorsque le signal de télévision est supérieur à un second niveau de signal. Le second niveau de signal est supérieur au premier niveau de signal. L'invention concerne également un appareil associé. Etant donné que le premier niveau du premier type de signal de télévision est inférieur, la réception du premier type de signal de télévision est améliorée.
