Abstract: A method for booting up an embedded system that can be booted up in a normal booting up mode or an exterior driver booting up mode. The method includes steps of powering up the embedded system and detecting whether there is an exterior driver. If there is an exterior driver, then it is determined whether there is a booting up module in the exterior driver. If there is a booting up module, then it is determined whether there is a chip setting sub-module in the exterior driver. If there is a chip setting sub-module in the exterior driver, then booting up images are displayed.

Abstract: A video device to generate analog video signals to a plurality of display devices comprises a video processing chip, a plurality of video output interface circuits and a plurality of detection circuits. The video processing chip converts input video data into the analog video signals and comprises at least one video decoder and a plurality of analog to digital convertors. The video output interface circuit transmits the analog video signals to the plurality of display devices. The detection circuit detects voltage of horizontal sync signals of the analog video signals to determine connection of the video output interface circuit to the display device, and generates a feedback signal to the video processing chip to control the video decoder and the analog to digital convertor accordingly.
