Abstract
An embodiment may include a method to convert a video signal with an analog to digital converter in a video decoder, convert an audio signal with the analog to digital converter, demodulate the audio signal with an audio demodulator and amplify the audio signal with a programmable gain amplifier before it is converted in the analog to digital converter. In an embodiment the programmable gain amplifier may receive a control signal from the audio demodulator to adjust the audio signal level. Another embodiment may provide a video decoder comprising a programmable gain controller, an analog to digital converter coupled with the programmable gain controller, the converter to digitize audio and video information, and an audio demodulator coupled with the analog to digital converter, the audio demodulator to control the programmable gain controller for an audio signal.
