Abstract

Disclosed is a processing architecture that converts a notebook computer into an audio/video playing device for directly playing an audio/video signal without activating a central processing unit of the notebook computer, wherein, without activating the central processing unit, the processing architecture receives an audio/video signal through an analog audio/video interface, which applies an analog signal to an analog-to-digital converter to provide a digital signal. The digital signal is then processed in sequence by an audio/video processor and a low voltage differential signaling (LVDS) processor to provide an LVDS signal that is selectively applied to a display screen and a speaker of the notebook computer to be played and/or broadcast by the display screen and the speaker.

Claims

1. A processing architecture adapted to work with a notebook computer that comprises a central processing unit, a display screen, and a speaker all powered by a power supply of the notebook computer, for directly playing an audio/video signal with the display screen and the speaker without activating the central processing unit of the computer, the processing architecture comprising an audio/video processing circuit that activates the display screen, the speaker, the audio/video processing circuit comprising:

an analog audio/video interface adapted to receive the audio/video signal from an external source;

an analog-to-digital converter that receives an analog signal from the analog audio/video interface and converts the analog signal into a first digital signal;

an audio/video processor that receives and processes the first digital signal and generates a second digital signal; and

a low voltage differential signaling processor that receives the second digital signal and generates and selectively applies an output signal to the display screen and the speaker.

2. The processing architecture as claimed in claim 1, wherein the audio/video processing circuit is powered by the power supply to electrically connect the display screen, the speaker, the audio/video processor, the analog audio/video interface, the analog-to-digital converter, and the low voltage differential signaling processor that communicate with each other for data transfer and exchange.

3. The processing architecture as claimed in claim 1, wherein the analog audio/video interface comprises a TV tuner.

4. The processing architecture as claimed in claim 1, wherein the analog audio/video interface comprises an AV/S terminal.

5. The processing architecture as claimed in claim 1 further comprising a control panel mounted to a casing of the notebook computer.

6. The processing architecture as claimed in claim 1 further comprising a remote control and a control signal receiver adapted to arranged in the notebook computer for receiving a control signal from the remote control to control the operation of the processing architecture.

7. The processing architecture as claimed in claim 5, wherein the control panel comprises a power key, a play/pause key, a next section play key, a previous section play key, a stop key, a fast-forward key, and a fast-backward key.

8. The processing architecture as claimed in claim 6, wherein the remote control comprises a power key, a play/pause key, a next section play key, a previous section play key, a stop key, a fast-forward key, and a fast-backward key.

9. The processing architecture as claimed in claim 5, wherein the control panel comprises a secondary display.
