Embodiment Construction

[0040] The invention provides a visual vehicle-mounted device based on an embedded microprocessor. Its main working principle is that a single-chip microcomputer controls the work of a DVD reading device and a digital TV chip, and the embedded microprocessor controls the work of a GPS navigation module, an infrared module, and a bluetooth module. Send commands to the single-chip microcomputer to control the work of the DVD reading device and the digital TV chip. All video data are processed by the embedded microprocessor and sent to a video display device for display. At the same time, the embedded microprocessor is also responsible for processing the menu operation interface display and video signal switching. Wait.

[0041] Below in conjunction with accompanying drawing of specification sheet and an optimal embodiment, the present invention is further elaborated and illustrated:

[0042] Such as figure 1 and 2Shown, a kind of visual vehicle-mounted equipment based on embed...

Abstract

The invention relates to a visual on-vehicle apparatus based on an embedded microprocessor, wherein the visual on-vehicle apparatus has a flexibly-operated menu and colorful application interfaces. The visual on-vehicle apparatus is provided with a DVD reading device used for reading a DVD disk and generating video data, an embedded microprocessor used for decoding the video data, a video displaying device used for displaying decoded video signals, and a storage device used for storing a control instruction and second video data correlated with the control instruction. The control instruction comprises a first control instruction which drives the DVD reading device to read the DVD disk. The embedded microprocessor obtains the first control instruction and transmits the first control instruction to the DVD reading device to drive the DVD reading device to read the DVD disk. Simultaneously, the second video data is embedded into the embedded microprocessor and then transmitted to the video displaying device for displaying.

Description

【Technical field】 [0001] The invention relates to a visualized vehicle-mounted device, in particular to a visualized vehicle-mounted device based on an embedded microprocessor with flexible menu operations and colorful application interfaces. 【Background technique】 [0002] There are many kinds of visual on-board devices. Take the car-mounted DVD navigation device as an example. The car-mounted DVD navigation device is a device that connects a GPS navigation board to the main board of the original car DVD to play both DVD and GPS navigation functions. In terms of video processing, car DVD navigation equipment is realized through single-chip microcomputer plus video decoding. With the continuous increase of functions, various functions need to be displayed on the same display screen, so they need to be controlled through menu options. To switch between different functions, an OSD is integrated in the video decoding chip, so that the visual on-board equipment has the function ...
