Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home entertainment lighting systems face challenges in compensating for variations in delay between content rendering and light effect rendering, which significantly impact the user experience, especially when precise synchronization is required.
Innovation Solution
An electronic device and method that determine information indicating delay variations and select appropriate light effects to be rendered simultaneously with content items, adjusting light effect rendering based on delay information to minimize synchronization issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a buffer is used to compensate for delay, then synchronization between content and light effects is improved, but the system cannot handle variation in delay effectively
Solution Approach 1:
The system dynamically adjusts the set of light effects based on real-time delay variation measurements. The processor continuously monitors delay variations and selects appropriate light effects from multiple options, allowing the system to adapt to changing synchronization conditions rather than relying on a fixed buffer approach.
Solution Approach 2:
The system changes the parameter of light effect selection based on delay variation. By measuring actual delay variations and using this information to select from multiple light effects, the system adjusts its behavior dynamically to maintain synchronization quality despite varying delay conditions.
2Adaptability or versatility
If multiple light effects are available for selection, then adaptability to delay variations is improved, but device complexity increases
Solution Approach 1:
The system segments the light effects into multiple distinct options that can be independently selected. Each light effect is a separate entity that can be chosen based on delay conditions, allowing the system to manage complexity through organized categorization rather than treating all effects as a single complex unit.
Solution Approach 2:
The system uses feedback from delay variation measurements to guide light effect selection. The processor continuously monitors actual delay and adjusts light effect choices accordingly, creating a closed-loop system that reduces complexity by using automated feedback-driven decision making rather than complex manual control.
3Reliability
If light effects are selected based on delay information, then user experience is improved, but measurement and processing requirements increase
Solution Approach 1:
The system uses self-service measurement techniques where the processor monitors delay variations internally without requiring external measurement devices. The delay information is gathered from the system's own operational data, reducing the need for complex external measurement infrastructure while maintaining reliable synchronization.

AI summary
An electronic device (1) is configured to determine information indicating or affecting a variation in delay, e.g. variations in one or more delay components (21-26), between a content frame being rendered, e.g. by a mobile device (12), and a light effect synchronized to the content frame starting to be rendered. The electronic device is further configured to select one or more light effects to be rendered simultaneously with a content item based on the determined information and cause one or more light sources (16, 17) to render the selected one or more light effects simultaneously with the content item.
