Network Video Wall Server Display Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video wall display systems are inflexible and limited by the length of signal transmission lines, restricting the distance between servers and displays, and making it difficult to scale or reconfigure according to application requirements.
Innovation Solution
A display system that uses a network to transmit images between servers and player devices, allowing for flexible configuration and scalability, where each player device receives and synchronizes image parts from servers over the network to display on video walls, eliminating distance limitations and enabling easy addition or removal of servers and displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional methods using graphics cards with multiple outputs connect to displays through single transmission lines, then the system can display images on video walls, but the system is limited by the length of signal transmission lines and lacks flexibility
Solution Approach 1:
The patent introduces a network as an intermediary medium between servers and player devices. Instead of direct physical connection through long signal transmission lines, the network serves as a mediator that transmits image data, eliminating the length limitation of traditional signal cables while maintaining system functionality.
Solution Approach 2:
The patent replaces the mechanical/electrical signal transmission system with a network-based data transmission system. This substitution allows for greater flexibility and eliminates the physical length constraints of traditional video signal cables, enabling remote deployment of video wall systems.
2Adaptability or versatility
If conventional methods use fixed server-display connections, then the system structure is simple, but the system cannot be easily scaled or reconfigured according to application requirements
Solution Approach 1:
The patent divides the video wall system into independent functional modules: servers for image rendering, player devices for reception and display control, and network for communication. This segmentation allows each component to be independently configured, added, or removed based on application needs, enabling easy scalability without requiring complex system-wide reconfiguration.
Solution Approach 2:
The patent creates a dynamic system architecture where the number and arrangement of servers and player devices can be adjusted according to application requirements. The network-based connection allows the system to adapt its configuration dynamically, supporting various display scenarios from small to large video walls without fixed structural constraints.

AI summary
A display system and a display method for video walls are provided. The display system includes at least one server and a plurality of player devices. Each server renders an image and transmits the image to a network. The player devices are coupled to the at least one server through the network. Each player device receives the image or a part of the image rendered by one of the at least one server, and determines a synchronization time together with at least one of the other player devices. Each player device uses a display of a video wall to simultaneously display the image or the part of the image at the synchronization time.
