Abstract:
1. A computer device capable of playing DVD films without the need of running an operating system, comprising: a computer keyboard unit comprising a keyboard controller, a low-voltage differential signal (LVDS) transmitter, wherein the LVDS transmitter has an output end connected to a liquid crystal display (LCD) monitor; a DVD-ROM for reading and outputting audio/video DVD data; a DVD format and image decoder connected to the DVD-ROM through a multiplexer, the DVD format and image decoder having an output end connected to an audio amplifier, which has an output end connected to a speaker, wherein an image processor connects the DVD format and image decoder with the LVDS transmitter, and wherein the DVD format and image decoder is used to transform the inputted IDE interface signals from the multiplexer into RGB digital signals and analog signals, then, the DVD format and image decoder outputs the RGB digital signals to the image processor, the image processor outputs RGB digital signals to the LVDS transmitter, the LVDS transmitter sends low-voltage differential signals to the LCD monitor for displaying, and wherein the analog signals are sent to the audio amplifier and then to the speaker; and a DVD control switch disposed on the computer keyboard unit and connected to the power switching module, wherein the power switching module functions as a controller when the DVD control switch is activated to turn on the work power of the keyboard controller, the DVD-ROM, the DVD format and image decoder, the multiplexer, the image processor, the LVDS transmitter, the LCD monitor, the audio amplifier, and the speaker.
