the data capture units 140 are configured to send the display data of the tiled display screens to the detection processing unit 110 and the cross configuration unit 120.

The detection processing unit 110 is configured to determine a synchronous splicing relationship of the plurality of display data according to a preset display detection rule, and send the synchronous splicing relationship to the cross configuration unit 120.
In the embodiment of the present invention, the preset display detection rule is associated with the brightness of the edge pixel of the plurality of display data, that is, the present invention determines the synchronous splicing relationship of the display data based on the brightness of the edge pixel of the display data, where the synchronous splicing relationship means that the display data of the spliced display screen along the time axis satisfies the splicing relationship within a certain synchronization time difference, and when the display data of the spliced display screen satisfies the splicing relationship within the certain synchronization time difference, the brightness of the edge pixel will satisfy the preset rule, specifically refer to the flowchart of the step of determining the synchronous splicing relationship of the plurality of display data according to the preset display detection rule shown in fig. 3.
As a preferred embodiment of the present invention, the data capture unit first copies the display data of the multiple tiled display screens into two identical copies through the copy circuit and sends the two identical copies to the detection processing unit and the cross configuration unit, respectively.

Taking a spliced display screen of 2X2 as an example, when a spliced screen of 2X2 is captured, for the existing capture system, each screen needs to be subjected to h.264 coding according to 2Mbps code stream, 2X2X2=8Mbps code stream is needed altogether, but the system adopting the invention can be recovered only by 2Mbps code stream, the definition is consistent with that of the existing system, and the more spliced display screens, the more obvious advantages of the invention are.

According to the remote transmission system of the spliced display screens, the synchronous splicing relation of the display data of the spliced display screens is identified, and then the display data are combined, so that the synchronism of the display data in the transmission process can be effectively ensured, namely on the premise of ensuring higher resolution, the synchronism of the data is ensured, and the viewing experience of a receiving end is improved.

And step S504, splicing the plurality of zoomed display data into merged display data according to the synchronous splicing relation of the plurality of display data.
In the embodiment of the invention, the zoomed display data is spliced into the merged display data according to the synchronous splicing relation of the display data,

In the embodiment of the present invention, the preset display detection rule is associated with the brightness of the edge pixel of the plurality of display data, that is, the present invention determines the synchronous splicing relationship of the display data based on the brightness of the edge pixel of the display data, where the synchronous splicing relationship means that the display data of the spliced display screen along the time axis satisfies the splicing relationship within a certain synchronization time difference, and when the display data of the spliced display screen satisfies the splicing relationship within the certain synchronization time difference, the brightness of the edge pixel will satisfy the preset rule, specifically refer to the flowchart of the step of determining the synchronous splicing relationship of the plurality of display data according to the preset display detection rule shown in fig. 3.
And step S606, splicing the display data of the spliced display screens into combined display data according to the synchronous splicing relation of the display data.
