Multiple output audio system
First Claim
1. A multiple output audio system, comprising:
- a second input buffer buffering a second data stream;
a second processing unit processing the second data stream received from the second input buffer, outputting a third data stream and a second output signal, wherein the second processing unit 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 the second output signal to drive a second output device;
a data buffer receiving the third data stream from the second processing unit;
a multiplexer having input terminals receiving a first audio signal and the third data stream from the data buffer, and an output terminal outputting an output data stream, wherein the output data stream is one of the first audio signal and the third data stream; and
a first processing unit coupled to the output terminal of the multiplexer, receiving and processing the output data stream to output a first output signal to drive a first output device.

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.
