The window abnormity display device of Table top type Video processing control platform
Technical field
The utility model is related to a kind of technical field of Video processing, particularly relates to a kind of Table top type Video processing control platform
Serial ports abnormity display device.
Background technology
LED display screens working site, generally requires many picture switchings, various images is switched to into LED display screens and is shown,
These images are generally from image that multiple stage field camera or in advance programmed video frequency program or computer are played etc., according to
The situation at program scene, it is sometimes desirable to show multiple different pictures simultaneously on one screen, such as many pictures superposition, picture-in-picture,
The display controls such as picture out picture, existing way is an external Multi image processor, or connection computer, in an operating system,
Processed using software.
The deficiencies in the prior art part:(1)Although existing multi-channel image processor system realizes picture-in-picture, picture out picture and many pictures
Face-port mouth display effect, such as double vision window, cross window, nine pictures, the even more many pictures of 16 pictures, but window shape is all rectangular
Shape, observation dead angle is easily formed in multi-channel image processor, and multiple pictures are easily covered each other when being superimposed, it is difficult to meet customer various
Change demand;(2)The decoder of Multi image processor is welded in inner panel on market, and number and type are fixed, user input
The video type or quantity that once built-in with the Multi image processor decoder of video is received misfits, and just cannot use, if
Standby poor compatibility;(3)Process is overlapped using software, easily because of system or the unstability of software, video data loss is made,
Cause LED display card screen or blank screen.Also, because computer needs to prestore video content in a hard disk, from hard disk
Editor is transferred, the content after having processed is then displayed on LED display that time delay will certainly be caused.
In view of this, the design people for above-mentioned prior art design on do not attain improve institute caused by it is many disappearance and not
Just, and deeply conceive, and actively research improvement has a fling at and develops and design the utility model.
Utility model content
The purpose of this utility model is to provide a kind of according to live needs, plays picture-in-picture, the picture out picture of special-effect graph
And the window abnormity display device of the Table top type Video processing control platform of many picture windows.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of window abnormity display device of Table top type Video processing control platform, it includes controller, memory, special-shaped window
Control module, Video processing map overlay device, the DDR of the multichannel that is stored with live video stream, premonitoring window and main output display screen,
Controller and memory, special-shaped window controlling module and Video processing map overlay device be connecteds, Video processing map overlay device and
DDR connects, and premonitoring window and main output display screen are connected with Video processing superimposer;The memory internal memory contains special-effect graph text
Part, special-shaped window controlling module is used as special-shaped window, video by least one special-effect graph in controller selection memory
Process map overlay device read selected special-shaped window choose to be played in DDR arbitrarily all the way video respectively with an abnormity
Window be superimposed, by Video processing map overlay device superposition mixture control by be superimposed with video special-shaped window and its
His other to be broadcasted video is exported to premonitoring window after being mixed, and switches to main output display after pre-monitoring frequency content again
Screen.
The controller includes a receiver module, and the special-effect graph file outside receiver module reception will by write buffer
Special-effect graph file is stored in memory.
The Table top type Video processing control platform has a cabinet, and the top of cabinet is have a mainboard in guidance panel, cabinet,
The controller, memory, Video processing map overlay device and DDR are arranged on mainboard and are connected with guidance panel, described different
Shape window controlling module, premonitoring window and main output display screen are arranged on guidance panel.
The controller is STMF32-2X7 chips.
The memory is SD card memory.
The Video processing map overlay device is EP4CE115F2917 chips.
After said structure, the serial ports abnormity display device of the utility model Table top type Video processing control platform is by control
Device processed and video video process map overlay device overlay video in special-shaped window, then video is mixed with background video, make to regard
Frequency display window can simultaneously include background video, and the special-shaped window video being superimposed upon on background video, on the background video
It is stackable to include various special-shaped windows with special-effect graph, such as heart, star, petal, geometric figure, without office
It is limited to existing square sprite, position, the size of special-shaped window not only can be set, it is also an option that being consistent with field condition
Special-effect graph, fully to show and show video information, the layout of special-shaped window is attractive in appearance various, can improve the experience of user
Sense.The utility model has completely disengaged from computer, using pure hardware structure, therefore, during editor, switching, input, output etc. all
Will not be because of the unstable loss for causing data of system.The process of another aspect the utility model is real-time video flowing, example
Such as on-the-spot broadcasting, concert or large-scale exhibition needs the real time information being displayed in real time on LED display, multiple video camera records
The video of system is input in real time the Table top type Video processing control platform and carries out after real-time processing, and instructor in broadcasting personnel adjust in real time according to field condition
Take special-effect graph and combined with live video stream as special-shaped window and be displayed on background video, should not video flowing directly abandon,
Not store, each video in premonitoring window directly passes through DDR operation.
