Video Wall Control System Single-Process Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video wall systems require separate control processes for CCTV images, split screens, and monitor merge/unmerge operations, leading to user inconvenience, limited monitor connectivity, and increased manufacturing costs, with most systems designed for personal computers and lacking extensibility and freedom for controlling multiple video walls.
Innovation Solution
A video wall control system comprising a client module, central control module, storage module, gateway module, and decoding module that enables single-process control of CCTV images, split screens, and monitor merge/unmerge operations, allowing connection of up to 36 PCs and 144 monitors, enabling multiple video walls to be controlled by a single PC and providing advanced layout management and event notification features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate control processes are used for CCTV images, split screens, and monitor merge/unmerge operations, then each function can be controlled independently, but user convenience deteriorates and system complexity increases
Solution Approach 1:
The patent merges separate control processes for CCTV images, split screens, and monitor merge/unmerge operations into a single integrated control process. The control system receives a single control command and simultaneously executes multiple operations (changing video sources, adjusting split screen layouts, and controlling monitor merge/unmerge) based on layout information stored in the storage module, eliminating the need for multiple separate control steps and improving user convenience.
Solution Approach 2:
The control system is designed with multi-functionality to handle diverse control operations through a universal interface. The single control command can trigger different operations (CCTV source switching, split screen configuration, monitor merging/splitting) depending on the current system state and stored layout information, allowing one control mechanism to serve multiple purposes.
2Area of stationary object
If multiple monitors are connected to increase video wall capacity, then display capability improves, but the number of images that can be displayed by each monitor decreases and system complexity increases
Solution Approach 1:
The patent segments the video wall system into modular components: multiple monitors are independently controllable units, each capable of displaying different video sources or portions of split screens. The control system manages each monitor individually through the single control process, allowing flexible configuration where monitors can be merged into a unified display or operated independently, thereby reducing overall system complexity while maintaining large display capacity.
Solution Approach 2:
The system dynamically adjusts monitor configurations based on control commands and stored layout information. Monitors can be dynamically merged to form a unified video wall or split to display independent content, allowing the system to adapt its structure in real-time. This dynamic reconfigurability enables the system to handle large numbers of monitors without requiring permanently complex wiring or control architectures.
3Adaptability or versatility
If wall controller and matrix switcher are both used to control video wall, then control functionality is comprehensive, but manufacturing cost increases
Solution Approach 1:
The patent merges the functionalities of the wall controller and matrix switcher into a single integrated control system. The control system includes a control unit that can directly manage video source switching and monitor configuration based on stored layout information, eliminating the need for a separate matrix switcher. This integration maintains comprehensive control functionality while reducing the number of required components and lowering manufacturing costs.
Solution Approach 2:
The control system is designed with multi-functionality to perform both wall controller tasks (monitor configuration, layout management) and matrix switcher tasks (video source switching, signal routing) through a single device. The control unit can interpret control commands and execute multiple operations simultaneously, providing the versatility of having both devices while reducing system complexity and cost.
4Ease of operation
If personal computer software is used to control CCTV screen, then control flexibility improves, but the system cannot be used to monitor people from a control center
Solution Approach 1:
The control system is designed with multi-functionality to operate in multiple modes: it can function as a flexible personal computer-based control system for general video wall management, and simultaneously serve as a control center monitoring system. The control unit can receive and process control commands from various sources and execute operations appropriate for both environments, allowing the same hardware and software platform to adapt to different operational contexts without sacrificing either flexibility or monitoring capability.
