In one embodiment, the KDF is the chip manufacturer. Other embodiments are described and claims. | 2010-07-22 |
| 20100183155 | ADAPTIVE REMASTERING APPARATUS AND METHOD FOR REAR AUDIO CHANNEL - Provided is an adaptive remastering apparatus and method for a rear channel, which emphasizes only signals of the rear channel while maintaining signals of other channels of a multi-channel audio signal. According to the adaptive remastering apparatus and method for a rear channel, virtual rear left and right channel audio signals are generated by multiplying a predetermined gain by ambient signals extracted from front left and right channel audio signals and are combined with input rear left and right channel audio signals, thereby increasing powers of signals of the rear channel. | 2010-07-22 |
| 20100183156 | AUDIO SYSTEM AND METHOD TO CONTROL OUTPUT OF THE AUDIO SYSTEM - An audio system and a method to control the output of the audio system are provided. The audio system includes a source unit having an audio signal, a receiver to receive the audio signal and generate a cancellation signal to cancel the audio signal, a first speaker to output the audio signal, and a second speaker to output the cancellation signal. | 2010-07-22 |
