Digital Lighting Control via Dual-Network Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital lighting systems face challenges in managing and synchronizing the control of multiple digital lights and media servers, particularly in preventing network traffic bottlenecks and ensuring seamless video and image projection across a distributed lighting system.
Innovation Solution
A dual-network system is implemented, where one network handles control commands for digital lights using a control assembly with a graphics engine, and another network handles media content distribution, allowing for real-time video streaming and synchronization of media servers, along with features like automated media distribution, image processing, and edge blending effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single network is used to handle both control commands and media content distribution, then device complexity is reduced, but network performance deteriorates due to traffic bottlenecks
Solution Approach 1:
The patent divides the network infrastructure into two separate networks: a control network for transmitting control commands and a media network for distributing video and image content. This segmentation prevents traffic bottlenecks by isolating control traffic from high-bandwidth media traffic, ensuring both control responsiveness and media delivery performance.
2Reliability
If multiple digital lights and media servers are synchronized in real-time, then lighting show quality is improved, but control complexity increases
Solution Approach 1:
The control assembly receives status information from digital lights and media servers, enabling real-time monitoring and adjustment of synchronization. This feedback mechanism ensures that all devices remain synchronized during the lighting show while providing the flexibility to handle unexpected conditions.
Solution Approach 2:
The control assembly acts as an intermediary between the control network and media network, coordinating control commands with media content distribution. It manages the synchronization between multiple digital lights and media servers, simplifying the overall control architecture while maintaining precise timing.
3Extent of automation
If automated media distribution is implemented across the network, then operational efficiency is improved, but network bandwidth consumption increases
Solution Approach 1:
Media content is pre-distributed to media servers before the lighting show begins. The automated system prepares and stores video and image content in advance on local media servers, reducing the need for real-time streaming during the show and thereby conserving network bandwidth while maintaining operational efficiency.

AI summary
A digitally controlled lighting system where aspects have a central media server connected to remote media servers. The connection may have separate networks for control versus media. Automatic synchronization of the contents of the media servers may be carried out.
