Multiscreen splicing system based on cluster master-slave structure

Abstract

The invention provides a multiscreen splicing system based on a cluster master-slave structure. The multiscreen splicing system is characterized in that at least two mutually independent smart display terminals are used for realizing multiscreen wireless splicing, wherein the smart display terminals comprise a master smart display terminal and at least one slave smart display terminal; the master smart display terminal and the at least one slave smart display terminal are connected through WIFI (wireless fidelity); the master smart display terminal receives multimedia information from a server and sends multimedia region information required to be displayed by the at least one slave smart display terminal to the at least one slave smart display terminal. According to the scheme, industrialized mass production as well as configuration modularization and standardization is facilitated, faults are easy to solve, infinite-quantity and flexible combinations can be realized, and the application prospects are broader.

Description

technical field [0001] The invention relates to a multi-screen splicing technology, in particular to a multi-screen splicing system based on a cluster master-slave structure. Background technique [0002] At present, the screen advertising systems on the market mostly use LCD or LED splicing technology. A large picture can be obtained through LED or LCD splicing, but when the modules are spliced, the product is very bulky, and the gap in the middle and power consumption are also low. Both are large and cost very high. [0003] In addition, there are also multi-screen processing technologies for splicing, but they all use a multi-screen expander for splicing, connect to a multi-screen expander through a data cable, and divide a screen into Multiple screens, and then perform image splicing. When performing image splicing, it is limited by the output interface of the multi-screen expander. If there are several output interfaces, only a few display terminals can be connected. T...

Problems solved by technology

[0002] At present, most screen advertising systems on the market use LCD or LED splicing technology. A large picture can be obtained through LED or LCD splicing. Both are large and cost very high

[0003] In addition, there are also multi-screen processing technologies for splicing, but they all use a multi-screen expander for splicing, connect to a multi-screen expander through a data cable, and divide a screen into multiple output ports through the multi-screen expander. Multiple screens, and then carry out image splicing. When performing image splicing, it is limited by the output interface of the multi-screen expander. If there are several output interfaces, only a few display terminals can be connected. The relationship between the display terminals is parallel. Primary and secondary, signal synchronization control is completed in the multi-screen expander

Occupies a relatively large bandwidth and cannot be combined flexibly indefinitely. The overall structure of the equipment is relatively complicated, which is not conducive to single fault resolution and industrial mass production.
