Abstract

A computer system includes a reading device, a host computing device, an audio-and-video reproducing device, and a switching device. The reading device is operable so as to read information from a storage medium. The switching device is coupled to the reading device, the host computing device, and the audio-and-video reproducing device, and is operable in one of first and second switch states. The host computing device is operable so as to convert the information read by the reading device into audio and video output signals when the switching device is in the first switch state. The audio-and-video reproducing device is operable so as to convert the information read by the reading device into the audio and video output signals when the switching device is in the second switch state.

Claims

1. A computer system, comprising:

a reading device operable so as to read information from a storage medium;

a host computing device;

an audio-and-video reproducing device; and

a switching device coupled to said reading device, said host computing device, and said audio-and-video reproducing device, said switching device being operable in one of a first switch state, where said switching device connects said reading device to said host computing device, and simultaneously disconnects said reading device from said audio-and-video reproducing device, and a second switch state, where said switching device connects said reading device to said audio-and-video reproducing device, and simultaneously disconnects said reading device from said host computing device,

wherein said host computing device is operable so as to convert the information read by said reading device into audio and video output signals when said switching device is in the first switch state,

wherein said audio-and-video reproducing device is operable so as to convert the information read by said reading device into the audio and video output signals when said switching device is in the second switch state, thereby permitting reproduction of the information in the storage medium even when said host computing device is in a non-booted state.

2. The computer system as claimed in claim 1, further comprising a remote controller operable so as to generate a user command signal, which is transmitted wirelessly, for controlling operation of said host computing device when said switching device is in the first switch state, and for controlling operation of said audio-and-video reproducing device when said switching device is in the second switch state.

3. The computer system as claimed in claim 1, further comprising:

a display controller coupled to said host computing device and said audio-and-video reproducing device, adapted to be coupled to a display device, and operable so as to provide the video output signal generated by said host computing device to the display device when said switching device is in the first switch state, and so as to provide the video output signal generated by said audio-and-video reproducing device to the display device when said switching device is in the second switch state; and

an audio controller coupled to said host computing device and said audio-and-video reproducing device, adapted to be coupled to an audio device, and operable so as to provide the audio output signal generated by said host computing device to the audio device when said switching device is in the first switch state, and so as to provide the audio output signal generated by said audio-and-video reproducing device to the audio device when said switching device is in the second switch state.

4. The computer system as claimed in claim 3, wherein said audio-and-video reproducing device includes an audio-and-video reproducing circuit that is coupled to said switching device and said display and audio controllers, and that converts the information read by said reading device into the audio and video signals.

5. The computer system as claimed in claim 4, wherein said audio-and-video reproducing device further includes an input-and-output interface coupled to said audio-and-video reproducing circuit of said audio-and-video reproducing device, and operable so as to provide the audio and video output signals from said audio-and-video reproducing circuit of said audio-and-video reproducing device as an output.

6. The computer system as claimed in claim 5, wherein said input-and-output interface is further operable so as to receive audio and video input signals from an external source.

7. The computer system as claimed in claim 6, wherein said audio-and-video reproducing device further includes a decoder coupled between said input-and-output interface and said display controller, and operable so as to decode the audio and video input signals received by said input-and-output interface, said display controller being further operable so as to provide a decoded output from said decoder to the display device.

8. The computer system as claimed in claim 7, wherein said audio-and-video reproducing device further includes a tuner coupled between said decoder and said input-and-output interface.

9. The computer system as claimed in claim 8, wherein said tuner is a television tuner.

10. The computer system as claimed in claim 1, wherein said reading device is an optical disc drive.
