Specifically, the synchronous playing system comprises a Web end, a spliced screen and a cloud management module, wherein the Web end, the spliced screen and the cloud management module are sequentially connected.
The Web end can be preset with a cloud cutting function, the cloud cutting can cut each frame of video, image signal source and the like in specific formats (such as MP4, AVI and MPEG), the conventional splicing, the special-shaped splicing and the like, and after recoding, each part forms independent cut content, so that at least one play content is obtained.
The Web end can import a file to be played, where the type of the file to be played may be an image, a video, and the like, and for example, the file to be played may be video data in an AVI format, and the like. After the cloud cutting function is started, a user can perform editing operations such as translation, scaling and cutting on video image data, and the arrangement effect of the equipment and the display effect of video content are visually displayed in the form of visual graphics.
For example, in some examples, a user may define a cut area in the Web end by a mouse or automatically form the cut area by a preset size of a tiled screen, so as to cut a file to be played input to the Web end according to the cut area to form the playing content.
The Web end also comprises the functions of making a play plan, managing a template, managing and setting a spliced screen and the like. The user can set the playing content through the function of formulating the playing plan and generate the playing plan of the playing content. The management template function can be used for managing a template which is set by a user or preset and used for processing a file to be played, and the management and the setting of the spliced screen can comprise but are not limited to adjusting the brightness, the color temperature or the switch of the spliced screen.
The Web end can transmit the playing plan, the playing content, the setting content and the like to the cloud management module, and then the playing plan, the playing content, the setting content and the like are transmitted to the corresponding spliced screen through the cloud management module.
The cloud management module can be a cloud server and can be connected with the spliced screen in a wired or wireless mode.
The cloud management module comprises an IOT communication module, a data transmission module and a data encryption module, wherein the IOT communication module is used for communicating with the spliced screen to monitor the state of the spliced screen and acquire information of the spliced screen. The data transmission module is used for receiving the playing plan, the playing content and the like transmitted by the Web end and sending the playing plan and the playing content to the corresponding splicing screen in a point-to-point mode.

And after the playing content and the playing plan are encrypted through a data encryption module of the cloud splicing management platform, the playing content, the playing plan and other data are transmitted to the corresponding splicing screen through a data transmission module.
Please refer to fig. 2, the number of the tiled screens is not limited, and the tiled screens form a large tiled screen according to the arrangement of the horizontal and vertical arrays.
The spliced screens can comprise processing devices, and the spliced screens can be connected with the same router through the processing devices to form a local area network, so that synchronous information interaction can be carried out between the spliced screens. After the spliced screen is spliced to form the large screen, the spliced screen can form a corresponding installation topological structure, and the installation topological structure is transmitted to the cloud management module. Therefore, the cloud management module can transmit video playing contents, playing plans and the like to the corresponding spliced screen in a point-to-point mode according to the installation topological structure.
In particular, the tiled screen can include a processing unit, a memory, and a communication unit. The communication unit is wirelessly connected with the router, so that a local area network is formed with other spliced screens to carry out synchronous information interaction, and the communication unit is used for receiving data such as playing contents, playing plans and other command requests transmitted by the cloud management module, and sending parameters of the spliced screens, running state information of the communication unit and the like. The memory may store the transmitted playback content and playback plan. The processor may play the corresponding video content according to the play plan, thereby playing the corresponding video content as planned.
Furthermore, an NTP time service mode is adopted between the spliced screen and the spliced screen, and the recording of NTP sending/receiving time stamps is realized by the cloud management module. The spliced screen and the spliced screen are kept synchronous, and therefore synchronous playing of the spliced screen is achieved.
Note that the NTP time service method is a Client (Client)/Server (Server) method.
In general, in a conventional NTP time service method, the following methods are adopted: the Client end sends an NTP packet to the Server end, wherein the NTP packet comprises a time stamp T1 when the packet leaves the Client end, when the Server end receives the packet, the time stamp T2 when the packet arrives and the time stamp T3 when the packet leaves are filled in sequence, and then the packet is immediately returned to the Client end. The client, upon receiving the response packet, records the timestamp T4 returned by the packet. The Client terminal calculates 2 key parameters by using time parameters of T1, T2, T3 and T4: the round-trip delay d of the NTP packet and the clock skew t between the Client and the Server. The client uses the clock offset to adjust the local clock to make its time coincide with the server time.
It can be understood that the latency of the local area network is relatively large in general, because the sending and receiving operations of the timestamp are generally performed in the application layer, and there is a latency in the processing due to occupation of other application programs when the processing is performed in the operating system kernel of the application layer. Therefore, in the application, the recording NTP sending/receiving timestamp is moved from the application program to the network layer, so that errors caused by uncertain processing delay of the kernel of the operating system can be eliminated. By the method, the NTP time service precision can be greatly improved to a mu s level in the local area network.
Referring to fig. 3, specifically, in the present application, one of the mosaic screens is used as a server, and the other mosaic screens are used as clients. T1 sends NTP request timestamp for Client (referred to Client time); t2 is the Server receiving NTP request time stamp (taking the Server time as reference); t3 replies NTP request time stamp for Server (using Server time as reference); t4 is the timestamp of the Client receiving the NTP reply packet (referred to the Client time); d1 is NTP request packet transmission delay, d2 is NTP reply packet transmission delay; t is the time offset between the Server and the Client, d is the round-trip time of the NTP packet.
Then, the processing time of the Server is T3-T2, and the total time from sending the request to receiving the response by the Server is T4-T1;
for example, if the time for the T1 Client to send the NTP request is 10:00:00am, the time for the T2 Server to receive the NTP request is 10:00:01am, the time for the T3 Server to reply the NTP request is 10:00:02am, and the T4 Client receives the NTP reply packet 10:00:03am, d is equal to (T4-T1) - (T3-T2) for 2 seconds
The time difference between the client and the server is as follows:
t ═ T2-T1) + (T4-T3)/2 is equal to about 1 s.
Therefore, the NTP time service precision between the spliced screen and the spliced screen is greatly improved.

For example, in a 2 × 3 tiled screen, the screen labels are, in order: spliced screen 1#, spliced screen 2#, spliced screen 3#, spliced screen 4#, spliced screen 5#, and spliced screen 6 #. After the relative position labels of the screen labels representing the positions of the spliced screens are acquired, the installation topological structure can be determined according to the relative position labels of the screen labels.
