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.
