Abstract
The utility model relates to the technical field of on-vehicle video, in particular to a device for previewing simultaneously by multiple video sources of an on-vehicle audio-visual multimedia system; the device mainly comprises an image cutting unit, a main processing unit, a displaying module and a power supply module; the image cutting unit, the main processing unit and the displaying module are electrically connected in sequence, and the power supply module supplies power to all the parts. The device effectively solves the problem of previewing by the on-vehicle multiple video sources simultaneously; therefore, the device can be widely applied to the on-vehicle multimedia system.
Description
Technical field
The utility model relates to the Vehicular video technical field, refers in particular to a kind of many video source of vehicle carried video multimedia system that realize and carries out the device of preview simultaneously.
Background technology
Along with growth in the living standard, development of science and technology, the vehicle carried video multimedia is also widely used along with the increase of automobile.For adapting to consumer demand, increasing function that vehicle carried video multimedia system on the market is integrated now, as: DVD plays, vehicle-mounted pick-up head, playback of media files, analog/digital TV etc.Most multimedias are to satisfy user's visual impression, all are provided with video capability; But present vehicle carried video multimedia system all simultaneously all can only show a kind of video, and perhaps the form with picture-in-picture shows two-path video, but can easily arbitrarily not switch.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of many video source of vehicle carried video multimedia system that can show many video source simultaneously and be convenient to switch to carry out the device of preview simultaneously.
The technical scheme that the utility model solves the problems of the technologies described above is: mainly include picture segmentation unit, Main Processor Unit, display module and power module, picture segmentation unit, Main Processor Unit and display module are electrically connected in regular turn; The power supply of electric power source pair of module each several part.
Described picture segmentation unit includes an image splitter, and its model is AP5200 or TW2835.
Described Main Processor Unit is connected with audio-frequency module.
Described Main Processor Unit is connected with gps receiver.
Described Main Processor Unit is connected with memory module.
The utility model is compressed in multi-channel video on the screen in same ratio by image splitter, perhaps, is presented on the screen with taking turns blanking time to export in order according to the full frame picture of user's needs with each video source input.Multi-channel videos such as DVD video, camera, media play/navigation video output, TV output are received the input of this dispenser, and the user just can be chosen in a plurality of video pictures of preview or each picture of full-screen preview simultaneously in turn on the display module.Thereby make the utility model device realize preview simultaneously of many videos or independent preview function.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing 1 is the structured flowchart of the utility model vehicle carried video multimedia system;
Accompanying drawing 2 is the utility model FB(flow block).
The explanation of accompanying drawing figure number
Picture segmentation unit 1 Main Processor Unit 2
Audio-frequency module 5 power modules 6
Embodiment
See accompanying drawing 1, vehicle carried video multimedia system of the present utility model mainly includes picture segmentation unit 1, Main Processor Unit 2, display module 3, memory module 4, audio-frequency module 5, power module 6 and gps receiver 7.Picture segmentation unit 1, display module 3, memory module 4, audio-frequency module 5 and gps receiver 7 are connected with Main Processor Unit 2; 6 pairs of each several part power supplies of power module.
Aforementioned picture segmentation unit 1 is the multi-channel video synthesis module, and its image splitter model can be AP5200 or TW2835.The image splitter of picture segmentation unit 1 synthesizes piece image with the image of multi-channel video input, also can with the full frame picture of each video source input in order with take turns gating blanking time, and output to Main Processor Unit 2 with the form of BT656.Main Processor Unit 2 will output to the LCD display demonstration of display module 3 through synthetic vision signal by the lcd controller of chip internal.Multipath video source can be DVD video, camera, media play/navigation video output, TV output etc.Multi-channel video can four cuts apart, nine cut apart and even more mode is simultaneously displayed on the screen.In addition, the user can select to want the video watched by clicking touch-screen; Send it to picture segmentation unit 1 by control line behind the signal of Main Processor Unit 2 reception touch-screens, the video source that the image splitter of picture segmentation unit 1 is selected the user is presented on the lcd screen with the full frame Main Processor Unit 2 that outputs to of the form of BT656 again.Think to carry out again the preview simultaneously of many video source as the user, can click touch-screen once more; Main Processor Unit 2 transfers a command to picture segmentation unit 1 by control line after receiving the signal of touch-screen again.
Described display module 3 models can be LMS700; In addition, Main Processor Unit 2 has the internal hardware coding/decoding module, the media file on the memory can be decoded.Main Processor Unit 2 also can move navigation software, thereby and media play/navigation video outputed to video d/a, after the digital-to-analogue conversion as the input of image splitter.
The voltage regulator of power module 6 provides needed various voltage for system, as 5V, 3.3V, 1.8V etc.
The utility model carry out single or many video previews FB(flow block) as shown in Figure 2, carry out initialization, image splitter setting after the system start-up; Show many pictures preview interface then.Carry out touch screen operation again, the judgement that quits a program, judge whether selected certain the road video of touch screen operation or quit a program that selected certain the road video of operation then shows this single video; Operate the then shutdown system that quits a program.The judgement that quits a program then, as quit a program, then shutdown system; As not being then to carry out touch screen operation once more to judge, judge whether selected many pictures preview.As selected many video previews, then dispose the picture distributor, show many pictures preview interface; Otherwise, the judgement of proceeding to quit a program.
