Abstract
A kind of three-dimensional system of coordinate video-splicing multiwindow data distributing method.The method includes: set up three-dimensional system of coordinate on mosaic screen, reads the video data that each display unit window is corresponding；According to each display unit window physical location in three-dimensional system of coordinate, calculate the coordinate recording each display unit window edge three-dimensional system of coordinate；Video distribution system, according to each display unit window edge coordinate received, calculates each display unit overlapping portion；After video distribution system is according to calculating each display unit overlapping portion video data, distributing each display unit video data, described three-dimensional system of coordinate includes X/Y plane coordinate system.The present invention is real by setting up three-dimensional system of coordinate on mosaic screen, read the boundary coordinate calculating each display unit, then video data is distributed by video distribution system, video playback is carried out again by each display unit, thus the data of each display unit need not be obtained from internal memory, save the data volume read from internal memory.
Description
Technical field
The present embodiments relate to technical field of video image processing, especially relate to a kind of three-dimensional system of coordinate video-splicing
Multiwindow data distributing method.
Background technology
Video-splicing processor is a kind of equipment that multiple video signal sources arbitrarily splice screen display at polylith.Institute
With, every piece of mosaic screen it is frequently necessary to output multiple different window, and the size and location of window can arbitrarily roam and superposition.
Owing to mosaic screen has fixed size, when opening multiple window, often there is the situation of superposition in window, at this moment by
In being only able to display the content of one of them window, the part of the window being blocked really cannot show.But, this portion
Divided data is the most unwanted.
Summary of the invention
The main purpose of the embodiment of the present invention is to provide a kind of three-dimensional system of coordinate video-splicing multiwindow data distribution side
Method, it solves the technical problem of the data volume how saving reading at least in part.To achieve these goals, it is provided that with
Lower technical scheme:
A kind of three-dimensional system of coordinate video-splicing multiwindow data distributing method, the method includes:
Mosaic screen is set up three-dimensional system of coordinate, reads the video data that each display unit window is corresponding；
According to each display unit window physical location in three-dimensional system of coordinate, calculate and record each display unit window edge three-dimensional
The coordinate of coordinate system；
Video distribution system, according to each display unit window edge coordinate received, calculates each display unit overlapping portion；
After video distribution system is according to calculating each display unit overlapping portion video data, distribute each display unit video data；
Described three-dimensional system of coordinate includes X/Y plane coordinate system, the X-axis of described X/Y plane coordinate system and Y-axis and the row and column in internal memory
Corresponding.
Compared with prior art, technique scheme at least has the advantages that
The present invention is real by setting up three-dimensional system of coordinate on mosaic screen, reads the boundary coordinate calculating each display unit, then leads to
Cross video distribution system distribution video data, then carry out video playback by each display unit, thus need not obtain from internal memory
The data of each display unit, save the data volume read from internal memory.
Embodiment
A kind of three-dimensional system of coordinate video-splicing multiwindow data distributing method, the method includes:
Mosaic screen is set up three-dimensional system of coordinate, reads the video data that each display unit window is corresponding；
According to each display unit window physical location in three-dimensional system of coordinate, calculate and record each display unit window edge three-dimensional
The coordinate of coordinate system；
Video distribution system, according to each display unit window edge coordinate received, calculates each display unit overlapping portion；
After video distribution system is according to calculating each display unit overlapping portion video data, distribute each display unit video data；
Described three-dimensional system of coordinate includes X/Y plane coordinate system, the X-axis of described X/Y plane coordinate system and Y-axis and the row and column in internal memory
Corresponding.
The present invention is real by setting up three-dimensional system of coordinate on mosaic screen, reads the boundary coordinate calculating each display unit, so
Distribute video data by video distribution system afterwards, then carry out video playback by each display unit, thus need not be from internal memory
Obtain the data of each display unit, save the data volume read from internal memory.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent.
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
