Abstract
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 the 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 the 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 the received television signal exceeds a second signal level. The second signal level is greater than the 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.
