Multiple output audio system

Abstract

The invention provides a multiple audio output system comprising a second input buffer storing a second data stream output from a demodulation unit or a demultiplexing unit, a second processing unit receiving and processing the second data stream to output a third data stream, a data buffer receiving a third data stream from the second processing unit, a multiplexer having input terminals receiving a first audio signal and the third data stream, and an output terminal outputting an output data stream, and a first processing unit receiving and processing the output data stream to output a first output signal to drive a first output device. The second processing unit further comprises a second decoder receiving and decoding the second data stream, and a second post processing unit receiving and processing the decoded second data stream to output a second output signal to drive a second output device.
