Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0027] like figure 1 As shown, taking a set of 5*4 splicing display system as an example, the signals displayed on the splicing display system are S-1, S-2, S-3, S-4, S-5, stacked and displayed status as figure 1 A method for recording screen images of a multi-screen splicing display system, comprising the following steps:
[0028] Step 1: Connect the control computer 1, the recording and broadcasting server 2 and all the display screens of the splicing display system 3 through Ethernet 4 to form a local area network. The position and layout of the screen image signal on system 3 are managed. The unit display screen is equipped with a display node machine. The display node machine is a small machine based on the X86 platform [with CPU]. The basic configuration requirements include memory DDR31G, hard disk 160G, running Linux or Windows oper...

The invention discloses a recording method for screen pictures of a multi-screen tiled display system. A control computer, a recording steaming server and all cell display screens forming the tiled display system are connected through the Ethernet to form a local area network; the screen pictures of the tiled display system are synchronously displayed by the control computer, and the control computer is responsible for performing management on positions and arrangement of screen picture signals on the tiled display system, and each cell display screen is provided with a display node computer; the input interface of each display node computer is connected with the Ethernet; the output interface of each cell node computer is connected with the corresponding cell display screen; firstly, all the picture signals to be recorded are converted into digital signals, and then, the digital signals and ID (identifier) numbers of the display node computers are packaged together into a node computer data packet on which network transmission can be performed, and the node computer data packet is transmitted to the recording steaming server to perform recording, and therefore recording on the picture signals determined by any box selection range on the screen of the multi-screen tiled display system or certain parts in the picture signals can be realized.
Description
technical field [0001] The invention relates to a screen image recording method, in particular to a screen image recording method for a multi-screen splicing display system. Background technique [0002] In the existing multi-screen splicing display system, the recording and broadcasting system is aimed at a single display signal, and can only record a certain channel or a few channels of image signals displayed on the large screen, and cannot record arbitrary selections on the large screen. image content, especially when some of these arbitrarily selected image contents are only part of a certain display signal. In the prior art, the signal to be displayed and the recorded signal are usually separated by a signal distributor, which is costly, inefficient, and time-consuming. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a screen image recording method of a multi-screen splicing display system that can arbitra...
