An embodiment of the present invention provides a method for automatically implementing multi-screen splicing, and referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of the method for automatically implementing multi-screen splicing according to the present invention.
In this embodiment, the method for automatically implementing multi-screen splicing includes the following steps:
step S10: and when a video splicing control instruction is received, acquiring a main video signal according to the video splicing control instruction.
It should be noted that the executing subject of this embodiment is an intelligent display device, and the intelligent display device may be an intelligent television, an intelligent display, or other devices having the same or similar functions as the intelligent television, which is not limited in this embodiment, and the intelligent display device is the main display device in fig. 3.
It can be illustrated that, this embodiment is applied to a process of displaying image information by multi-screen splicing, and determines how to display the image information by acquiring a video splicing control instruction, and then completes transmission of video content and the control instruction through video data transmission channels connected between the displays, and finally completes display of a corresponding picture on each screen, and the pictures form a complete image, thereby implementing a process of displaying a video by multi-screen splicing.
It should be noted that the video stitching control instruction is information required by the user, and the video image needs to be displayed on several screens, for example: and displaying the image according to two rows and three columns, wherein the two rows and three columns are display requirement information of the user, and outputting the image through 6 screens of 2x 3. The input mode required by the user can be input through handwriting input or input equipment, and the video splicing control instruction input by the user can be acquired through detecting a screen or receiving an input equipment signal correspondingly.
In this embodiment, a specific manner of obtaining the video splicing control instruction may be that the video splicing control instruction performs feature detection on the voice control information by obtaining the voice control information, and when preset voice information is detected, the video splicing control instruction is obtained according to the voice control information, where the preset voice information is feature voice, for example: two rows and three columns or two times three, etc., wherein the manner in which the voice control information can obtain the video stitching control instruction can also be other manners such as keyword recognition, which is not repeated herein in this embodiment.
In a specific implementation, a main video signal is obtained according to the video splicing control instruction, and when a video splicing requirement exists, corresponding video information to be played is obtained according to the video splicing control instruction, wherein the video to be played is the main video signal.
In addition, as shown in fig. 3, the main display device may include a plurality of video input modules, each corresponding to a different main video information obtaining manner, for example: HDMI input, high-definition video input or local storage, and then output to the sub-display system through the HDMI interface, and the video concatenation control instruction can be through modes such as UI input or speech input, wherein, the main display device can interact through every equipment UART port (Universal Asynchronous Receiver Transmitter/Transmitter) with the control signal interaction of other sub-display device, and in the middle of it, every video display device can be connected together through the HDMI interface in series.
Step S20: and generating video splicing information according to the video splicing control instruction.
It should be noted that, according to the video splicing control instruction, video splicing information may be generated, where the video splicing information includes the coordinates of the main display device and the change rule of the device coordinates, so as to be recognized by subsequent devices, for example: the main display device transmits current position information (coordinates (m, n) of the current device in the system and display matrix information [ h, v ] to a next sub display device or a display module through a UART port (Universal Asynchronous Receiver/Transmitter), the next sub display device calculates the coordinate information of the current device according to the total matrix information after receiving the information of the previous device, cuts an input signal source according to the coordinate information, as shown in a transfer diagram of control information in fig. 3, as shown in fig. 3, a display matrix of 2x3, i.e. 2 rows and 3 columns, and 6 screens in total, 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 sends (1,0) [2,3] to the sub display device 1, and the sub display device 1 judges whether the current is the last device after receiving the information, if not, the number of rows or columns in the position information is changed and sent out, at this time, (2,0) [2,3] is sent out, the sub-display device 2 receives the position information and sends out (2,1) [2,3] to the sub-display device 3, and recursion is carried out in sequence until the last sub-display device, in fig. 3, the sub-display device 5.
Step S30: and obtaining a target sub video signal according to the video splicing information and the main video signal.
It should be noted that this embodiment provides a preferred scheme for acquiring a target sub video signal, for example: each display module calculates how to divide the current video signal according to its own position information (x, y) [ h, v ], (x, y) as the current display module position information, [ h, v ] as a display matrix, that is, how to divide the video signal into display forms according to the video splicing control command, for example: the display matrix is divided into six videos with two rows and three columns, and then 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 the display signal of the main display device is cut. The width and height of the video signal source are Sigw and Sigh. The main display device cuts the input signals, coordinates of the cut signals are used as starting points (0,0), the cut width and the cut height are (Sigw/v, Sigh/h), and the video processing unit amplifies the signals through the chip to achieve the full-screen display effect. And after receiving the complete signal, the sub-display device 2 simultaneously transmits the complete signal to the next sub-display device until the last sub-display device, simultaneously cuts the signal, and meets the requirement of self full-screen display, wherein the cutting coordinate point of the signal source by the sub-display device 2 is (Sigw/v,0), and the width and the height of the cut signal are (Sigw/v, Sigh/h). Each module in the first row cuts the signal by coordinates (x (Sigw/v),0), and intercepts the signal width and height (Sigw/v, Sigh/h). (x represents the horizontal position number of the display module in the matrix, and v represents the column number of the current display system) each module in the second row has the signal clipping coordinates of (x (Sigw/v), Sigh/h) and the signal width and height of (Sigw/v, Sigh/h) are clipped. And in the same way, each module in the Nth row cuts the signal into the coordinates of (x (Sigw/v), N (Sigh/h), and intercepts the width and the height of the signal (Sigw/v, Sigh/h). Through the image segmentation processing, each display module is a part of a complete image, a complete picture is displayed in the whole matrix, the whole splicing system only needs the main display equipment to play the picture, the main display equipment automatically distributes instructions to the next module according to the number of lines and columns of the picture set by a user, a link relation receiving instruction is formed among the modules, each module can output the received complete signal to the next module through the hdmi, and each module automatically segments according to coordinate information to finally complete display. The above preferred embodiments are only used for describing the present embodiment, and are not to be considered as limiting the present embodiment, and if different connection modes or connection orders occur, only the change rule of the coordinates needs to be adjusted.
Step S40: and displaying according to the target sub-video signal.
It should be noted that the target sub video signal is a picture signal that needs to be displayed by the main display device, and is a video signal corresponding to a part of an image displayed by the main video signal, and the display can be performed according to the target sub video signal, for example: in fig. 3, the main display device shows 1/6 parts of the image displayed by the main video signal, a part of the image in the upper left corner.
Step S50: and sending the main video signal and the video splicing information to a sub-display system, wherein the sub-display system at least comprises a sub-display device, so that the sub-display device obtains a sub-video signal corresponding to the sub-display device according to the video splicing information and the main video signal, and displays the sub-video signal according to the sub-video signal to finish full-automatic multi-screen splicing.
In this embodiment, further, the main video signal and the video splicing information are sent to the sub-display system as described in fig. 3, the sub-display system at least comprises one sub-display device, the video display of the sub-display device comprises the step of 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, determining a display matrix according to the video splicing information, cutting the main video signal according to the coordinate information and the display matrix to obtain a sub video signal corresponding to the sub display device, and displaying according to the sub video signal, therefore, the sub-display device acquires the sub-video signal in the same manner as the main display device, and can acquire the sub-video signal only by intercepting the image signal corresponding to the current position at different coordinate positions.
Further, the number of video blocks to be spliced does not necessarily have to be related to the number of actual sub-display devices, for example: when the total display equipment connected is a 4 × 4 matrix, the video splicing control command is 3 × 4, only 3 rows of displays including the main display equipment are displayed, and the video splicing display can still be completed according to the video splicing control command.
In a specific implementation, the embodiment provides an optimal implementation scheme for an implementation process of a full-automatic multi-screen splicing method, for example: as shown in fig. 4, the number of lines and columns of a spliced image is set by obtaining voice input information and video input information, an input signal is divided according to coordinate information of current equipment, the image is amplified until full-screen display is met after the divided input signal is obtained, whether the current display equipment or a display module is the last one is judged, if not, coordinate information of next display equipment is obtained according to a preset rule, the coordinate information of the next display equipment and the whole video signal are sent to the next display equipment, and the process is repeated until the last display equipment completes full-automatic multi-screen splicing. Through the image segmentation processing, each display module is a part of a complete image, a complete picture is displayed in the whole matrix, the whole splicing system only needs the main display device to play the picture, the main display device automatically distributes an instruction to the next display device according to the number of lines and columns of the picture set by a user, a link relation receiving instruction is formed among the display devices, each display device can output the received complete signal to the next display device through the hdmi, and each display device automatically segments according to coordinate information to finally complete display. Because each sub-display device is completed according to the instruction of the main display device, other display devices do not need to be set, and the setting in the main display device only needs to be adjusted when the display is met.
When a video splicing control instruction is received, a main video signal is obtained according to the video splicing control instruction; generating video splicing information according to the video splicing control instruction; obtaining a target sub video signal according to the video splicing information and the main video signal; displaying according to the target sub-video signal; and sending the main video signal and the video splicing information to a sub-display system, wherein the sub-display system at least comprises a sub-display device, so that the sub-display device obtains a sub-video signal corresponding to the sub-display device according to the video splicing information and the main video signal, and displays the sub-video signal according to the sub-video signal to finish full-automatic multi-screen splicing. In this way, the realization does not need to accomplish full-automatic many screens under the condition of connector and relies on, owing to need not set for alone every module, all modules are automatic to be accomplished, and the system is built conveniently, saves the peripheral hardware module, saves front end equipment, and the debugging is convenient, for the enterprise greatly improves the installation effectiveness, has reduced the cost of realizing many screens concatenation.

Step S32: and determining the cutting size according to the video splicing information and the main video signal.
It can be understood that, according to the video splicing information, the signal to be cut is one-half of the main signal, and then the cutting size is determined according to the image size displayed by the main video signal.
In this embodiment, the specific implementation steps may be: determining a total image size from the main video signal; determining a cutting size according to the total image size and the video splicing information, and determining a display matrix according to the video splicing information; determining a cutting proportion according to the display matrix; and determining the cutting size according to the total image size and the cutting proportion. 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 is 1: and 9, cutting 1/9 to the size of the main video signal.
Step S33: and cutting the main video signal according to the coordinate information and the cutting size of the current equipment to obtain a target sub video signal.
In this embodiment, the specific manner of acquiring the sub-video signal may be as follows: determining a cutting start coordinate point according to the coordinate information of the current equipment; and cutting the main video signal according to the cutting starting coordinate point and the cutting size to obtain a 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 the display signal of the main display device is cut. The width and height of the video signal source are Sigw and Sigh. The main display device cuts the input signals, coordinates of the cut signals are used as starting points (0,0), the cut width and the cut height are (Sigw/v, Sigh/h), and the video processing unit amplifies the signals through the chip to achieve the full-screen display effect. Further subsequent sub-display modules can all be referred to as above.
