Abstract
A tuner is controlled to manage noise and distortion levels in a video signal. The tuner recovers an RF modulated video signal. A video demodulator provides a baseband video signal from the recovered RF modulated video signal. At least one of signal-to-noise ratio (SNR) and intermodulation distortion (IMD) is determined for the baseband video signal. An AGC attack point of the tuner is dynamically controlled in response to the SNR and/or IMD in order to improve the video quality.
