Distributed Video Bridge for Matrix Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video wall systems require complex and costly centralized control processes, leading to inefficiencies in processing and displaying multiple video sources, as they lack the capability to simultaneously process multiple input signal sources, resulting in segmented content presentation across display devices.
Innovation Solution
A distributed control processing system using an embedded video bridge and video switch, connected via display data channels (DDCs) or a serial communication interface (SCI), dynamically allocates and adjusts video signals to individual intelligent display devices, enabling flexible and efficient video content segmentation and integration across a matrix of display screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a centralized control process using a high-end video server is used, then the video wall system can process and display video content, but the system complexity and cost increase significantly
Solution Approach 1:
The patent divides the centralized video processing function into multiple distributed intelligent display devices. Each display device independently processes video signals received through DDC channels, eliminating the need for a single complex video server. The video wall is segmented into multiple zones, each handled by individual intelligent display devices with independent processing capabilities.
Solution Approach 2:
Each intelligent display device performs self-processing of video content without requiring a centralized video server. The display devices autonomously receive video signals through DDC channels, process the content locally, and display it on their screens, thereby serving themselves rather than relying on external centralized control.
2Productivity
If a centralized control process is used, then video content can be displayed, but the capability to simultaneously process multiple input signal sources is limited
Solution Approach 1:
The video wall is divided into multiple independent display zones, each handled by an intelligent display device. Multiple video input sources can be simultaneously distributed to different DDC channels, which then route them to appropriate display devices for parallel processing and display without requiring complex centralized switching.
Solution Approach 2:
Each intelligent display device is designed with universal processing capability to handle multiple types of video input signals. The DDC channels provide multi-functional connectivity, allowing any video source to be routed to any display device, enabling flexible simultaneous processing of multiple signal sources with standardized interfaces.
3Productivity
If a high-end video server is used for centralized control, then video content can be processed, but the system cost increases
Solution Approach 1:
The patent replaces expensive high-end video servers with multiple relatively inexpensive intelligent display devices. Each display device performs video processing functions that would otherwise require costly dedicated hardware, thereby reducing overall system cost while maintaining processing capability through distributed architecture.
Solution Approach 2:
The intelligent display devices perform self-processing of video content without requiring a separate expensive video server. By integrating processing capabilities directly into the display devices, the system eliminates the need for costly centralized processing hardware while maintaining full video processing functionality.
4Ease of operation
If video content is segmented and displayed on corresponding display devices, then the display can be achieved, but the processing and display efficiencies decrease
Solution Approach 1:
Each intelligent display device autonomously processes and displays video content assigned to it through DDC channels without requiring centralized segmentation and routing control. This self-service approach maintains content distribution flexibility while improving processing efficiency by eliminating the sequential operations of centralized segmentation and display.
