  In the current development of automobiles, apart from emphasizing the improvement of the driving performance of the car itself, the importance of highly enjoyable and multifunctional functions that can be provided to the driver from the in-vehicle equipment is also increasingly emphasized. And, the AV satellite navigation system for vehicles, that is, the multimedia AV broadcasting platform in which satellite road condition navigation and AV control are matched (integrated) is emphasized. And it can be seen that this AV satellite navigation system for vehicles is always equipped on high-end models imported from abroad.

  Referring to FIG. 1, this is a block schematic diagram in which a conventional vehicle AV satellite navigation system is expanded with a circumscribed satellite navigation device. First, it can be seen that the vehicle AV satellite navigation system 7 mainly comprises a control host computer 71, a control panel 73, a satellite navigation device 75, an AV broadcast (reproduction) device 77, and a display panel 79. In the manufacturing process of the vehicle, the demand in the local market is always the main point of the design. Therefore, when the vehicle is shipped, the AV satellite navigation system 7 for the vehicle, that is, the local map data is combined and incorporated in the AV navigation device 75. By doing so, the satellite road condition navigation operation is provided.

  However, the above-mentioned method always ignores the demand of other regional markets, and still does not relatively incorporate the map data of other countries' markets, and vehicles equipped with such an AV satellite navigation system for vehicles always map. This causes the fact that only satellite navigation operations can be provided for normal use in locations that match the data, but this phenomenon also always appears in luxury cars imported from abroad on the market.

  Therefore, in order to solve such an existing problem, the existing method is an extra equipment, and as shown in FIG. 1 again, one tuner is provided in the input interface 81 of the vehicle AV satellite navigation system 7. (TV Tuner) 83 is circumscribed, for example, European and American television reception systems adopt the PAL system, but Asian countries often use the NTSC system, and the operation of this tuner 83 is the image between PAL and NTSC Provide format conversion and the source of the tuner 83 signal is from one circumscribing satellite navigation device 85, which is the map data of the current location in the vehicle and the satellite road condition navigation operation. Can provide.

  Obviously, providing local satellite road condition navigation operations from the circumscribing satellite navigation device 85 via the tuner 83 solves that the vehicle AV satellite navigation system does not yet include local map data. This is the preferred method. However, such a system directly outputs a screen for satellite road condition navigation operation to the vehicle AV satellite navigation system 7 by an external method, but the vehicle AV satellite navigation system 7 Is not compatible with providing a complete function that coexists with navigation and sound broadcasting at the same time. In other words, when the satellite navigation function is operated, the music broadcast cannot be listened to, and if the adjustment of the music is insufficient in the redundant driving process, the driving becomes less clogged and less pleasant.

  The main purpose of the present invention is to provide a conversion interface for a vehicle AV satellite navigation system, which can perform navigation as well as listen to music.

Screen data can be switched to display the second screen data input from the outside of the vehicle AV satellite navigation system, but the second screen data can be displayed by the vehicle AV satellite navigation system. The video AV converter for converting the video signal to be in conformity with the video AV system and the push button message of the AV satellite navigation system for vehicles connected to the video converter for decoding the first screen. Output display screen from data or second screen data The and a video control unit for determining.

  In order to achieve the above object, the present invention provides a conversion interface for a vehicle AV satellite navigation system, and the conversion interface is electrically connected between the vehicle AV satellite navigation device and one external satellite navigation device. The vehicle AV satellite navigation system is composed of one control host computer, one control panel, one satellite navigation device, one AV broadcast (playback) device, and one display panel. A video conversion device that outputs a screen in conformity with a screen format that can be displayed by an AV satellite navigation system for vehicles by providing a video format conversion electrically connected to the circumscribed satellite navigation device And control And a video controller for selecting one of the control host computer and the individual output the screen of the image conversion device by decoding the channel of the push button message to the display panel.

  The features and technical contents of the present invention will be described with reference to the following detailed description of the present invention and the accompanying drawings. However, the attached drawings are provided for reference and explanation only and are not to be used to further limit the present invention. Absent.

  Referring to FIG. 2, this is a block schematic diagram in which the conversion interface of the vehicle AV satellite navigation system of the present invention expands the circumscribed satellite navigation device. Matching (integration) so that the conversion interface 1 is connected between the vehicle AV satellite navigation system 2 and the external satellite navigation device 31 and the conversion interface 1 is provided inside the vehicle AV satellite navigation system 2 However, the operation of the vehicle AV satellite navigation system 2 can be made compatible. In the present invention, the vehicle AV satellite navigation system 2 can mainly provide satellite navigation and sound broadcast operation simultaneously, but the satellite navigation here is achieved by a circumscribed device, and the vehicle AV satellite navigation system 2 is mainly Occurs when local map data is not built-in.

  The vehicle AV satellite navigation system 2 shown in FIG. 2 mainly includes a control host computer 21 that provides operation of each item, a control panel 23 that provides pressing of a push button, and satellite navigation that provides navigation of road conditions. It includes a device 25, an AV broadcast (playback) device 27 that provides sound and video broadcast (playback), and a display panel 29 that provides screen output.

  The conversion interface 1 of the present invention includes one video control device 10 and one video conversion device 11. The video control apparatus 10 is electrically connected to the control panel 23 and the output terminal of the control host computer 21, and acquires one push button message S1 and one first screen data V1, respectively. 1 screen data V1 is generated from the inside of the vehicle AV satellite navigation system 2 and is displayed in response to pressing of the push button of the control panel 23, for example, an operation screen when listening to sound, System standby screen or video broadcast screen.

  On the other hand, the circumscribing satellite navigation device 31 is electrically connected to the video conversion device 11, the video conversion device 11 accepts the second screen data V2 output from the circumscribing satellite navigation device 31, and the second screen. By providing the data V2 such that the image format is converted into the second screen data V3, the image format conforms to the image format that can be displayed by the vehicle AV satellite navigation system 2.

  The video control apparatus 10 in the present invention outputs the fourth screen data V4 to the display panel 29, and the fourth screen data V4 is based on the content of the push button message S1. Alternatively, it is determined that the third screen data V3 can be output to the display panel 29 and displayed, that is, the fourth screen data V4 is one of the first screen data V1 and the third screen data V3.

  Referring to FIG. 3, the push button signal input interface 107 in the video control apparatus 10 receives the push button message S 1 output from the control panel 23 and is electrically connected to the output terminal of the push button signal input interface 107. By providing decoding to the push button message S1 from the connected decode unit 105, one push button decode message S2 is obtained. The screen (video) input interface 101 receives the first screen data V1 and the third screen data V3, and receives the first screen data V1 and the third screen data V1 from the screen switching unit 103 based on the push button decode message S2. One of the three screen data V3 is selected to be output to the display panel 29.
