Memory 1005 can be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as disk memory. In an embodiment, the memory 1005 may also be a storage device independent of the aforementioned processor 1001 .

Those skilled in the art can understand that the structure shown in Figure 1 does not constitute a limitation on the fully automatic realization of multi-screen splicing equipment, and may include more or less components than shown in the figure, or combine some components, or different Part placement.

In the fully automatic multi-screen splicing device shown in Figure 1, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; in the fully automatic multi-screen splicing device of this application The processor 1001 and memory 1005 can be set in the fully automatic multi-screen splicing device, and the fully automatic multi-screen splicing device calls the fully automatic multi-screen splicing program stored in the memory 1005 through the processor 1001, and executes the application The embodiment provides a fully automatic multi-screen splicing method.

An embodiment of the present application provides a fully automatic method for realizing multi-screen splicing. Referring to FIG. 2 , FIG. 2 is a schematic flowchart of a first embodiment of a fully automatic method for realizing multi-screen splicing according to the present application.

In this embodiment, the fully automatic method for realizing multi-screen splicing includes the following steps:

Step S10: when receiving the video mosaic control instruction, acquire the main video signal according to the video mosaic control instruction.

It should be noted that the execution subject of this embodiment is a smart display device, and the smart display device may be a smart TV, a smart display, or other devices with the same or similar functions as a smart TV. This is not limited, and the intelligent display device is the main display device in FIG. 3 .

It can be explained that this embodiment is applied to the process of displaying image information that requires multi-screen splicing, by obtaining video splicing control instructions to determine how to display, and then completing the video content and control instructions through the video data transmission channels connected to each other Finally, each screen displays the corresponding picture, and these pictures form a complete image, thus realizing the process of multi-screen splicing and displaying video.

It should be noted that the video splicing control command is the user's demand information, and the video image needs to be displayed on several screens, for example: the image is displayed in two rows and three columns, and the two rows and three columns are the user's display requirements information, and output images through 6 screens of 2*3. The input method required by the user can be input by handwriting or input device, and the video splicing control instruction input by the user can be obtained by detecting the screen or receiving the signal of the input device correspondingly.

In this embodiment, the specific manner of obtaining the video splicing control instruction may also be that the video splicing control instruction is to obtain voice control information, perform feature detection on the voice control information, and when preset voice information is detected, according to The voice control information obtains the video splicing control instruction, and the preset voice information is the characteristic voice, for example: two rows and three columns or two times three, etc., wherein the voice control information can be obtained in other ways to obtain the video splicing control instruction. Ways such as keyword recognition are not described here in this embodiment.

In a specific implementation, the main video signal is obtained according to the video splicing control instruction, and when there is a need for video splicing, the corresponding video information to be played is obtained according to the video splicing control instruction, and the video to be played is the main video signal .

In addition, as shown in Figure 3, the main display device may include multiple video input modules, and each video input module corresponds to a different main video information acquisition method, for example: HDMI input, high-definition video input or local storage, and then through HDMI output to the sub-display system, and the video splicing control command can be input through UI or voice input, among which, the control signal interaction between the main display device and other sub-display devices can be through each device UART port (Universal Asynchronous Receiver Transmission Universal Asynchronous Receiver/Transmitter) to interact, in which each video display device can be connected in series through the HDMI interface.

Step S20: Generate video splicing information according to the video splicing control instruction.

It should be noted that video splicing information can be generated according to the video splicing control instruction, and the video splicing information includes the device coordinates of the main display device, and the change rule of the device coordinates for identification by subsequent devices, for example: the main display device passes UART port (Universal Asynchronous Receiver Transmitter Universal Asynchronous Receiver/Transmitter), which transmits the current location information (coordinates (m, n) of the current device in the system and display matrix information [h, v] to the next sub-display device or display module, and the next sub-display device receives After the information of the last device, calculate the coordinate information of the current device according to the total matrix information, and cut the input signal source according to the coordinate information, as shown in the transmission diagram of the control information in Figure 3. As shown in Figure 3, it is a 2x3 display matrix, namely 2 rows and 3 columns, a total of 6 screens, the coordinate information of the main display device is (0,0), the display matrix information is [2,3] (representing 2 rows and 3 columns), the main display device will send (1,0) [2,3] to sub-display device 1, sub-display device 1 judges whether it is the last device after receiving the information, if not, continue to change the number of rows or columns in the position information and send it out at this time (2,0 )[2,3], sub-display device 2 receives this location information and then sends (2,1)[2,3] to sub-display device 3, recursively until the last sub-display device, in Figure 3 the sub-display device 5.

Step S30: Obtain a target sub-video signal according to the video splicing information and the main video signal.

It should be noted that this embodiment presents a preferred solution for obtaining the target sub-video signal, for example: each display module is based on its own position information (x, y) [h, v], (x, y) is the current display module Position information to calculate how to divide the current video signal, [h, v] is the display matrix, which is the display form of the video signal divided into video splicing control instructions, for example: six pieces of video divided into two rows and three columns, At this time, the display matrix is [2, 3]. The coordinate information of the main display device is (0,0)[2,3]. The main display device transmits the complete signal to the next module or device through hdmi, and cuts its own display signal. The width and height of the video signal source itself are Sigw and Sigh. The main display device cuts the input signal, the coordinates of the signal cutting are the starting point (0,0), the intercepted width and height are (Sigw/v, Sigh/h), and the video processing unit amplifies the signal through the chip to achieve Full screen display effect. After the sub-display device 2 receives the complete signal, it transmits to the next sub-display device until the last sub-display device at the same time, and at the same time cuts the signal to meet its own full-screen display. The clipping coordinate point of the sub-display device 2 for the signal source is ( Sigw/v,0), the intercepted width and height are (Sigw/v,Sigh/h). The signal clipping coordinates of each module in the first line are (x*(Sigw/v), 0) , intercept signal width and height (Sigw/v, Sigh/h). (x represents the number of horizontal positions of the display module in the matrix, and v represents the number of columns of the current display system) The coordinates of each module in the second row for signal clipping are (x*(Sigw/v), Sigh/h), intercepting the signal width High (Sigw/v, Sigh/h). By analogy, the coordinates of each module on the Nth line are (x*(Sigw/v), N*Sigh/h) to intercept the signal width and height (Sigw/v, Sigh/h). After the above image segmentation processing, each display module is a part of the complete image, and the entire matrix displays a complete picture. The entire splicing system only needs the main display device to play the picture. The main display device is based on the number of screen lines set by the user. And the number of columns, automatically distribute the instructions to the next module, form a link relationship between the modules to receive instructions, each module can output the received complete signal to the next module through hdmi, each module is divided according to the coordinate information, and finally Complete display. The above preferred solution is only used to illustrate this embodiment, and is not considered as a limitation to this embodiment. If there are different connection modes or connection sequences, it is only necessary to adjust the change rule of the coordinates.

Step S40: Display according to the target sub-video signal.

It should be noted that the target sub-video signal is the picture signal that the main display device needs to display, and the video signal corresponding to a part of the image displayed by the main video signal can be displayed according to the target sub-video signal, for example: Figure 3 , the main display device displays 1/6 of the image displayed by the main video signal, a part of the image in the upper left corner.

Step S50: Send the main video signal and video splicing information to a sub-display system, the sub-display system includes at least one sub-display device, so that the sub-display device can obtain The sub-video signal corresponding to the sub-display device is displayed according to the sub-video signal to complete fully automatic multi-screen splicing.

In this embodiment, further, as shown in Figure 3, the main video signal and video splicing information are sent to the sub-display system, the sub-display system includes at least one sub-display device, and the video of the sub-display device The display includes determining the coordinate information corresponding to the sub-display device according to the video splicing information, the coordinate information can be obtained according to the video splicing information sent by the main display device or the previous sub-display device, and the display matrix is determined according to the video splicing information , according to the coordinate information and the display matrix, the main video signal is clipped to obtain the sub video signal corresponding to the sub display device, and the sub video signal is displayed according to the sub video signal. Therefore, the way the sub display device obtains the sub video signal and the main display The equipment is the same, just have different coordinate positions to intercept the image signal corresponding to the current position to obtain.

Furthermore, the number of spliced video blocks is not necessarily related to the actual number of sub-display devices. For example: when the total connected display device is a matrix of 4*4, and the video splicing control command is 3*4, only the display including The 3-line display including the main display device can still complete the video splicing display according to the video splicing control instructions.

In the specific implementation, this embodiment proposes a preferred implementation scheme for the implementation process of the fully automatic multi-screen splicing method, for example: as shown in Figure 4, the number of rows and columns of the spliced image are set by obtaining voice input information and video input information According to the coordinate information of the current device, the input signal is divided, and the divided input signal is obtained, and the image is enlarged until the full-screen display is satisfied, and it is judged whether the current display device or display module is the last one. If not, the next one is obtained according to the preset rules. Display the coordinate information of the device, send the coordinate information of the next display device and the entire video signal to the next display device, and repeat this process until the last display device to complete fully automatic multi-screen splicing. After the above image segmentation processing, each display module is a part of the complete image, and the entire matrix displays a complete picture. The entire splicing system only needs the main display device to play the picture. The main display device is based on the number of screen lines set by the user. and the number of columns, automatically distribute the instructions to the next display device, and form a link relationship between the display devices to receive instructions, and each display device can output the received complete signal to the next display device through hdmi, each display device according to the coordinates The information is segmented by itself, and the display is finally completed. Since each sub-display device is completed according to the instructions of the main display device, there is no need to set up other display devices, and only need to adjust the settings in the main display device when encountering display.

In this embodiment, when the video splicing control instruction is received, the main video signal is obtained according to the video splicing control instruction; the video splicing information is generated according to the video splicing control instruction; the target sub-video is obtained according to the video splicing information and the main video signal signal; display according to the target sub-video signal; send the main video signal and video splicing information to the sub-display system, the sub-display system includes at least one sub-display device, so that the sub-display device according to the The sub-video signal corresponding to the sub-display device is obtained from the video splicing information and the main video signal, and is displayed according to the sub-video signal, so as to complete fully automatic multi-screen splicing. Through the above method, the fully automatic multi-screen can be completed without the need for a connector. Since there is no need to set each module separately, all modules are automatically completed, the system is convenient to build, and the peripheral modules are saved, saving front-end equipment and debugging. It is convenient, greatly improves the installation efficiency for enterprises, and reduces the cost of realizing multi-screen splicing.

The signal is clipped to obtain the sub-video signal corresponding to the sub-display device, and displayed according to the sub-video signal, so the sub-display device obtains the sub-video signal in the same way as the main display device, except that there are different coordinate positions to intercept the current The image signal corresponding to the position can be obtained.

Step S32: Determine the cropping size according to the video splicing information and the main video signal.

It can be understood that, according to the video splicing information, a fraction of the main signal of the signal to be cropped can be obtained, and then the cropping size is determined according to the image size displayed by the main video signal.

In this embodiment, the specific implementation steps may be: determine the total image size according to the main video signal; determine the cropping size according to the total image size and video splicing information, and determine the display matrix according to the video splicing information; The display matrix determines the cropping ratio; the cropping size is determined according to the total image size and the cropping ratio. The total image size is the display size of the main video signal, and the cropping ratio is the ratio of the sub video signal to the total video signal, for example: when the display matrix is [3, 3], then the ratio of the sub video signal to the total video signal at this time It is 1:9, and the cropping size is 1/9 of the main video signal size.

Step S33: Cutting the main video signal according to the coordinate information and the cutting size of the current device to obtain the target sub-video signal.

In this embodiment, the specific method for obtaining the sub-video signal may be as follows: determine the starting coordinate point for cutting according to the coordinate information of the current device; cut the main video signal according to the starting coordinate point for cutting and the cutting size, and obtain Target sub video signal. For example: the coordinate information of the main display device is (0,0)[2,3], the main display device transmits the complete signal to the next device through hdmi, and cuts the display signal itself. The width and height of the video signal source itself are Sigw and Sigh. The main display device cuts the input signal. The coordinates of the signal cutting are the starting point (0,0), and the intercepted width and height are (Sigw/v, Sigh/h). The video processing unit amplifies the signal through the chip.
