With further reference to fig. 3, a schematic structural diagram of an embodiment of the monitor screen splicing system provided by the present disclosure is shown. Like the monitor screen splicing system in the embodiment of fig. 2, the monitor screen splicing system in this embodiment may also include a screen projection source 1, a user control terminal 2, a screen splicing device 3, and a decoder 4. For a specific structural relationship, reference may be made to the related description in the embodiment of fig. 2, which is not described herein again.

The display screen 5 may be a device having an image function. The display screen may be a display screen capable of displaying a plasma, liquid crystal, rear projection, or the like. The decoder is connected with the display screen in a communication mode, wherein the decoder is configured to decode the coded video set to obtain a monitoring image set; the decoder is further configured to send the set of monitoring images to the display screen. The monitoring image may be an image obtained by decoding each compressed screen image, i.e., a set of encoded videos, acquired from the screen projection source.
Unlike the monitor screen splicing system in the embodiment of fig. 2, the decoder in this embodiment is configured to send the screen splicing result to the display screen; the display screen is configured to display the monitoring image set based on the screen stitching result. The screen stitching result may be a layout of each compressed screen image, i.e. the encoded video set, obtained from the screen projection source. The display screen can lay out the monitoring image set according to a screen splicing result and display videos corresponding to the laid coded video set.

Here, the screen capture of the computer screen may be implemented by using a GDI (Graphics Device Interface). Under the conditions that the configuration is I5 2330cpu, the memory is 4G and the display resolution is 1080p, the time for capturing a screen by the GDI is within 30ms, and the actual requirement can be met. After the screen capture, the screen image set obtained by the screen capture may be compressed and encoded to obtain an encoded video set. The compression encoding may be performed in a variety of ways. For example, the existing mature video compression algorithms H264, mpeg4, mpeg2, wmv, etc. In the case of a local area network gigabit switch, if the bandwidth is sufficient, the transmission of the code stream above 20Mbps (or more) can be allowed. On the other hand, since the decoder needs to decode the encoded video sets at the same time, the requirements for resources such as cpu are higher. So in practice a compromise may be made to use mpeg2 encoding format for compression. The usage amount of the central processing unit is within 30 percent of H264 during mpeg2 encoding and decoding. The actual requirement can be satisfied by calculating according to 25 frames per second of the video. In addition, the set of encoded videos may be transmitted to the screen-splicing device and the user control terminal using a transmission control protocol/internet protocol.

And determining a display area information set and a display area position information set of a screen included in the display screen corresponding to the decoder based on the area division information. And transmitting the set of display area information and the set of display area position information to the decoder. The area division information may be information of each area in the display screen. Here, the screen stitching device may receive the screen stitching scheme information and the encoded video set transmitted from the screen projection source using a transmission control protocol/internet protocol network. And then, the screen splicing equipment calculates the spliced window to obtain the region segmentation information. Then, a set of display region area information and a set of display region position information of the screen included in the display screen corresponding to each decoder are obtained from the region division information. And finally, distributing the display area information set and the display area position information set to each decoder through a transmission control protocol/internet protocol network. Optionally, after the display screen receives and decodes the encoded video set to obtain the screen video, the screen video is displayed on the display screen by using a DirectX technology according to the display area information set and the display area position information set. Among other things, directX is a multimedia programming interface that can make computers a technology to run and display applications with rich multimedia elements (e.g., full color graphics, video, 3D animation, and rich audio).
Unlike the monitor screen splicing system in the embodiment of fig. 2, the display screen in this embodiment includes screens including a superimposing screen and a flat screen. The overlay screen may be a screen suspended in any area of the display screen. The tiled screen may be a screen fixed in the display screen and not movable at will.
The above embodiments of the present disclosure have the following advantages: the monitoring screen splicing system of some embodiments of the present disclosure splices the monitoring screen, and fully exerts the function of a large screen. Specifically, the reason why it is difficult to sufficiently exert the function of the large screen is that: in the existing large screen splicing process, a large screen splicing matrix is configured, so that an intermediate connection link is added between a decoder and a large screen, fault points are increased, and the decoding efficiency is reduced.
