Processing architecture for directly playing audio/video signal
First Claim
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.

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.
