Image Intelligent Synchronization Method Based on Optical Fiber Distributed Display System

Abstract

The invention discloses an image intelligent synchronization method based on an optical fiber distributed display system. The method is used to synchronize the data collected by each image node. The node sending the synchronization signal can be any node, and intelligent matching and matching can be realized between each node. Intelligent substitute to ensure uninterrupted transmission of synchronous signals. This method is simple and reliable, and any node can be designated as an active synchronization node. Even if the synchronization signal of the distributed display system is lost, the remaining nodes can also realize intelligent substitute switching, so that the system can continue to work normally and prevent images from being displayed on the display wall. Image tearing caused by out-of-sync occurs.

Description

technical field [0001] The invention relates to an image display method, in particular to an image intelligent synchronization method based on an optical fiber distributed display system. Background technique [0002] The optical fiber distributed display system is an image processing system that collects, distributes, receives and integrates image data on a large-scale display wall (such as figure 1 shown). Because the amount of data is huge during distribution, when the network condition is relatively poor, the data of the same signal source received by different display nodes may not be in the same frame, and the intuitive performance is that the screen will be torn; It is particularly important to add an image synchronization mechanism to the system. [0003] However, the synchronization mechanism of manufacturers in the current industry has the following defects: it designates a certain distributed node (encoding sending node or decoding display node) as a synchroniza...

Problems solved by technology

[0003] However, the synchronization mechanism of manufacturers in the current industry has the following defects: it designates a certain distributed node (encoding sending node or decoding display node) as a synchronization source to provide image synchronization signals for the entire display system. When the synchronization node is damaged or removed In the future, the system will not work normally, and the display screen will appear blurry, and the entire display system will be paralyzed.
