SYSTEM AND METHOD FOR LEVEL CONTROL AT A RECEIVER

摘要

A system for controlling a volume level of television program audio data comprising a first automatic gain control unit having a first threshold value, a first target value, a first smoothing time and a first recovery rate, configured to receive an audio input and to generate an audio output. A second automatic gain control unit having a second threshold value, a second target value, a second smoothing time and a second recovery rate, configured to receive the audio output of the first automatic gain control unit and to generate a second audio output, wherein the first threshold value is less than the second threshold value.
