Abstract:
1. A connection device capable of mixing a red-green-blue (RGB) graphics signal and a luminance-bandwidth-chrominance (YUV) video signal comprising: a graphics transforming module for transforming the RGB graphics signal into a YUV graphics signal; a mixing module connected to the graphics transforming module for receiving the YUV video signal and the YUV graphics signal from the graphics transforming module, the mixing module outputting a YUV signal after mixing the YUV video signal and the YUV graphics signal; a first switching module for receiving the RGB graphics signal, the first switching module including: a video transforming module connected to the mixing module for transforming the YUV video signal into an RGB video signal; a second switching module for receiving the YUV video signal, the second switching module including: an output interface directly connected to the mixing module for receiving the output of the mixing module; and a basic input-output system (BIOS) for selecting one of the two outputs of the first switching module to output the RGB graphics signal and for selecting one of the two outputs of the second switching module to output the YUV video signal according to the output interface connected to the mixing module; wherein the mixing module is capable of receiving the RGB graphics signal and the RGB video signal, and outputting an RGB signal after mixing the RGB graphics signal and the RGB video signal.
