Abstract
The present invention is a system and method for improving the audio quality during a in a living-room type of environment having multimedia equipment. In accordance with an embodiment of the present invention, the audio signals emanating from various speakers are modified/altered, so as to capture audio signals with the highest signal to noise ratio. One situation where embodiments of the present invention are usable is in the context of a video/audio call. Since the positions of the microphone and speakers are generally fixed, in some embodiments, the speaker outputs are controlled/modified to provide an improved signal-to-noise ratio. In accordance with one embodiment, the audio emanating from the central speaker is subdued or eliminated to reduce significantly the problems that occur due to the audio from the center speaker being captured by the microphone, which is typically in close proximity to the center speaker. The audio may be provided to the speakers by various ways, such as HDMI, RCA, and so on.
