Abstract:
A vehicular audio/video system according to the present invention comprises: an expansion device for generating an output signal; an output device for receiving the output signal; an optical disc device for generating a first input signal to the expansion device; a detachable media storage device for generating a media data to the expansion device which processes the media data into a second input signal; and a handheld communication device for generating a communication data to the expansion device which processes the communication data into a third input signal. The expansion device selects the first input signal to be the output signal under an optical disc mode, selects the second input signal to be the output signal a media play mode, and selects the third input signal to be the output signal under a communication mode.
Abstract:
A car-use extended device is applied to electrically communicate to a car-use audio device to form a car-use control system, so as to simulate a user-to-machine operation interface for controlling an electronic computing device installed with an operation system to execute at least one preset assignment. The car-use audio device comprises an operation interface comprising a trigger element and at least one working signal input element. The extended device comprises a micro control unit comprising an interface-function setting program. When the trigger element is triggered, a triggering signal is generated and sent to the micro control unit, and the interface-function setting program is provided to define the preset assignment that the working signal input element represents. Hereafter, when the working signal input element is triggered, the micro control unit outputs a working signal to the electronic computing device, so as to make the electronic computing device execute the preset assignment.
