It usually describes).
The mosaic screen that various sizes of display screen to be spliced splices is shown in Fig. 5, including a big ruler
The display screen (1920x1080) of very little display screen (3840x2160) and 5 identical small sizes, large-sized display screen with it is small
Piece between display screen is 20, and the piece between small size display screen is 10.In one embodiment, mosaic screen container dimensional
It is 5780x3260.
The difference of Fig. 6 and Fig. 3 is, is the lateral spelling that 9 pieces of display screens to be spliced (3 × 3) are spliced into shown in Fig. 3
Screen is connect, 9 pieces of display screens to be spliced (3 × 3) in Fig. 6 are spliced into vertical mosaic screen.In one embodiment, the spelling of rectangle
The size for connecing screen container is 3260x5780.
It is the mosaic screen for the irregular shape that 8 pieces of display screens to be spliced are combined into shown in Fig. 7, each piece to be spliced aobvious
The size of display screen is all 1920x1080, and the piece between display screen is 10, and mosaic screen container dimensional is 5780x3260.
It is the mosaic screen for the irregular shape that 4 pieces of display screens to be spliced are combined into shown in Fig. 8, each piece to be spliced aobvious
The size of display screen is all 1920x1080, and the piece between display screen is 10, and one of display screen to be spliced has rotated 45 °,
Mosaic screen container dimensional is 5780x4133.
S104, the video for obtaining each display screen to be spliced export basic size.
The video output basic size of each display screen to be spliced refers to that each display screen to be spliced can allow to regard
The maximum length and maximum width of frequency output, generally also pixel indicate.For example, incorporated by reference to Fig. 3, display screen 1 to be spliced,
The video output basic size of display screen 2 ... display screen 9 all, i.e., is all 1920x1080 (pixel).
S106, the basic size and source of media overall window for obtaining source of media overall window are in the coordinate system of mosaic screen
Coordinate.
The basic size of source of media overall window refers to the total length and overall width of source of media overall window.Source of media is whole
Coordinate of the window in the coordinate system of mosaic screen indicate also with (x, y, long, wide), wherein：X and y indicates that source of media is whole
Coordinate of the window top left corner apex in the coordinate system of mosaic screen, the long and wide overall length and beam overall for indicating source of media overall window are logical
In normal situation, the length of source of media overall window and wide conversion imaging are usually described.
In one embodiment, media are obtained toward a source of media overall window is dragged on mosaic screen from boundary element
Coordinate of the basic size and source of media overall window of source overall window in the coordinate system of mosaic screen.
It is structural schematic diagram of the source of media overall window in Fig. 3 in an embodiment incorporated by reference to Fig. 4, Fig. 4.Media in Fig. 4
4 vertex of source overall window are located at the geometric center of display screen 1 to be spliced, display screen 2, display screen 4, display screen 5,
Source of media overall window is divided into 4 source of media child windows (child window 1, child window 2, child window 3, child window 4).
S108 obtains the displaing coordinate of source of media child window on each display screen to be spliced and each to be spliced
The video output coordinate of display screen.
Spliced according to coordinate of the source of media overall window in the coordinate system of mosaic screen and each display screen to be spliced
The displaing coordinate of the source of media child window on each display screen to be spliced and every is calculated in coordinate in the coordinate system of screen
The video output coordinate of a display screen to be spliced.Wherein, the displaing coordinate of source of media child window is based on source of media integral window
The coordinate system of mouth, video output coordinate is the coordinate system based on each display screen to be spliced.That is, source of media child window
Coordinate be from the point of view of in the coordinate system of source of media overall window, the video output coordinate of each display screen to be spliced be from
From the point of view of in the coordinate system of each display screen to be spliced.
In one embodiment, central server according to coordinate of the source of media overall window in the coordinate system of mosaic screen and
Coordinate of each display screen to be spliced in the coordinate system of mosaic screen, is calculated the matchmaker on each display screen to be spliced
The video output coordinate of the displaing coordinate of body source child window and each display screen to be spliced.
In one embodiment, continuing with Fig. 4 is combined, since 4 vertex of source of media overall window are located at wait spell
The geometric center of the display screen 1, display screen 2, display screen 4, display screen 5 that connect, source of media overall window are divided into 4 source of media
Window (child window 1, child window 2, child window 3, child window 4).The coordinate system of so source of media overall window is whole with source of media
The top left corner apex of body window is coordinate origin (and top left corner apex of child window 1).The coordinate system of display screen 1 to be spliced
It is with the coordinate origin for the coordinate system that the top left corner apex of display screen 1 to be spliced is display screen 1 to be spliced, to be spliced is aobvious
The coordinate system of display screen 2 is former with the coordinate for the coordinate system that the top left corner apex of display screen 2 to be spliced is display screen 2 to be spliced
Point, and so on.
So, the coordinate according to source of media overall window in the coordinate system of mosaic screen and each display screen to be spliced exist
Coordinate in the coordinate system of mosaic screen, the displaing coordinate that the source of media child window on display screen 1 to be spliced is calculated can
It is indicated with utilization (x, y, long, wide, θ), wherein：X and y indicates the top left corner apex of source of media child window in source of media integral window
The coordinate of the coordinate system of mouth, the long and wide overall length and beam overall (i.e. the size of source of media child window) for indicating source of media child window are logical
In normal situation, the length and width of source of media child window are converted into the pixel of source of media child window to describe, and θ indicates source of media child window
Rotation angle in the coordinate system of source of media overall window；The video output that display screen to be spliced each of is calculated is sat
Mark can use (x, y, long, wide, θ) also to indicate, x and y indicate the top left corner apex of source of media child window each to be spliced
Display screen coordinate system coordinate, the long and wide overall length and beam overall (the i.e. ruler of source of media child window for indicating source of media child window
It is very little), θ indicates rotation angle of the source of media child window in the coordinate system of each display screen to be spliced.
It can be expressed as continuing with the displaing coordinate in conjunction with Fig. 4, the source of media child window 1 on display screen 1 to be spliced
(0,0,960,540,0), the video output coordinate of display screen 1 to be spliced are (960,540,960,540,0)；To be spliced
The displaing coordinate of source of media child window 2 on display screen 2 can be expressed as (960,0,960,540,0), display screen 2 to be spliced
Video output coordinate be (0,540,960,540,0), other source of media child windows and so on.
S110, according to the access address of source of media overall window, the basic size, each to be spliced of source of media overall window
The video output basic size of display screen, the displaing coordinate of source of media child window on each display screen to be spliced and every
Video in the video output coordinate output source of media overall window of a display screen to be spliced.
According to the access address of source of media overall window, the basic size, each to be spliced aobvious of source of media overall window
The video output basic size of display screen, the coordinate of source of media child window on each display screen to be spliced and each to be spliced
