Abstract
The utility model provides an on-vehicle DVD navigation device which comprises the following components: an interface module, a power management module and a video conversion module. The interface module is electrically connected with a vehicle reversing rear-view camera and the video conversion module. The interface module is used for receiving an analog RGB signal which is output from the vehicle reversing rear-view camera and outputting the analog RGB signal to the video conversion module. The video conversion module is used for converting the analog RGB signal to a composite television broadcast signal and outputting the composite television broadcast signal to the interface module. The power management module is used for supplying power to the video conversion module. The on-vehicle DVD navigation device provided by the utility model converts the analog RGB signal to the composite television broadcast signal, thereby obtaining higher compatibility.
Description
Technical field
The utility model relates to a kind of guider, relates in particular to a kind of Vehicular DVD navigation unit.
Background technology
The part automobile is equipped with the vehicle backing backsight camera at present, when this class automobile need install the DVD guider additional, because the video signal format of the vehicle backing backsight camera that it carries output is rgb format, different from the video signal format that the DVD guider can be identified and show, therefore, existing DVD guider can't be connected with the vehicle backing backsight camera use.
The utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of Vehicular DVD navigation unit that can compatible rgb format vision signal.
A kind of Vehicular DVD navigation unit, comprise interface module, power management module and video conversion module, described interface module is electrically connected to a vehicle backing backsight camera and described video conversion module, described interface module is used for receiving the analog rgb signal of this vehicle backing backsight camera output, and exports this analog rgb signal to described video conversion module; Described video conversion module is used for described analog rgb signal is converted to Composite Video Broadcast Signal, and exports this Composite Video Broadcast Signal to described interface module; Described power management module is used for to described video conversion module power supply.
Further improvement of the utility model is, described DVD guider also comprises master controller, and described master controller is electrically connected to described power management module; Described master controller is used for controlling described power management module and powering to video processing module, and when described vehicle backing backsight camera quits work, control described power management module and stop to power to video processing module when described vehicle backing backsight camera work.
Further improvement of the utility model is, described video processing module comprises input circuit, change-over circuit and output circuit, and described input circuit is used for receiving described analog rgb signal from described interface module, and exports change-over circuit to; Described change-over circuit is used for described analog rgb signal is converted to described Composite Video Broadcast Signal and exports described output circuit to; Described output circuit is used for exporting described Composite Video Broadcast Signal to described interface module.
Further improvement of the utility model is that described change-over circuit is the video processing circuits of core for adopting the CXA1645M integrated circuit.
Compared to prior art, the vision signal that the analog rgb vision signal that Vehicular DVD navigation unit described in the utility model is exported the vehicle backing backsight camera by video processing module is converted to Composite Video Broadcast Signal shows, therefore, when this Vehicular DVD navigation unit of user installation, the vehicle backing backsight camera that can directly use automobile to carry has improved the compatibility of Vehicular DVD navigation unit.
Description of drawings
Fig. 1 is the functional block diagram of the utility model Vehicular DVD navigation unit.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further specified.
See also Fig. 1, the utility model provides a kind of Vehicular DVD navigation unit 10, comprises master controller 11, interface module 12, power management module 13 and video processing module 14.Interface module 12 is electrically connected to an external power source 20 and a vehicle backing backsight camera 30.Interface module 12 is used for receiving the analog rgb signal of vehicle backing backsight camera 30 outputs, and exports Composite Video Broadcast Signal corresponding to this analog rgb signal (composite video broadcast signal, CVBS).
Master controller 11 is electrically connected to power management module 13.Master controller 11 is used for when 30 work of vehicle backing backsight camera, and control power management module 13 gives video processing module 14 power supplies; And when vehicle backing backsight camera 30 quit work, control power management module 13 stopped to video processing module 14 power supply, so that video processing module 14 quits work, thus saves energy.
Compared to prior art, the vision signal that the analog rgb vision signal that Vehicular DVD navigation unit 10 described in the utility model is exported vehicle backing backsight camera 30 by video processing module 14 is converted to CVBS shows, therefore, when this Vehicular DVD navigation unit 10 of user installation, the vehicle backing backsight camera 30 that can directly use automobile to carry has improved the compatibility of Vehicular DVD navigation unit 10.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
