Dynamic Light Scripting via Video Audio Weights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic light scripting methods for dynamic lighting systems often fail to accurately match the light effects with the video and audio content, requiring significant user input for adjustment.
Innovation Solution
A system and method that allow users to influence video and audio weights to determine light effects, using information from video and audio content, such as music metadata, to create a more contextual and synchronized light script without requiring extensive user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic light scripting methods are used, then the amount of user input is reduced, but the light effects do not fit well with the content
Solution Approach 1:
The system dynamically adjusts the balance between automatic and manual control by allowing users to set weights for different content types (video, audio, metadata). This enables the light scripting system to adapt its degree of automation based on user preferences and content characteristics, resolving the contradiction between automation extent and accuracy.
Solution Approach 2:
The patent introduces weight parameters that control the influence of different content sources on light effect generation. By adjusting these parameters, users can fine-tune the accuracy of light effects while maintaining automatic scripting functionality, thus resolving the contradiction between automation and precision.
2Manufacturing precision
If manual creation of light script is performed, then the light effects fit the content well, but the task is daunting and time-consuming
Solution Approach 1:
Instead of requiring complete manual creation or complete automation, the system performs partial manual action by allowing users to adjust weights and select preferences. This partial user input significantly reduces the daunting nature of manual creation while maintaining good content fit, resolving the time-accuracy trade-off.
Solution Approach 2:
The weight parameters serve as intermediaries between automatic generation and manual control. Users interact with these simple weight parameters rather than directly creating complex light scripts, reducing the time and effort required while maintaining accuracy through the intermediary control mechanism.
3Device complexity
If only video content is used for light effect determination, then the process is simple, but audio information that could enhance synchronization is ignored
Solution Approach 1:
The system merges multiple information sources (video content, audio content, metadata) into a unified light effect determination process. By combining these sources with configurable weights, the system maintains relative simplicity while significantly improving audio-visual synchronization reliability.
Solution Approach 2:
The light scripting system is designed to universally process multiple types of input (video, audio, metadata) through a single unified framework. This multi-functionality allows the system to leverage diverse content sources without proportionally increasing complexity, improving synchronization while maintaining manageable system design.
4Adaptability or versatility
If multiple content sources (video, audio, metadata) are integrated, then the light effects are more contextual, but the determination process becomes more complex
Solution Approach 1:
The system manages the complexity of processing multiple content sources by introducing weight parameters that control the contribution of each source. This parameter-based approach allows flexible integration of video, audio, and metadata while keeping the determination process manageable through uniform weighted combination rather than complex multi-source processing logic.

AI summary
A method of determining light effects based on analysis of media content comprises allowing (401) a user to influence a video weight and an audio weight. The video weight represents a weight of video content in the determination of the light effects and the audio weight represents a weight of audio content in the determination. The method further comprises obtaining (405) information relating to the video content and/or information relating to the audio content, determining (407) the light effects to be rendered while the media content is being rendered. The method also comprises storing a light script specifying the light effects and/or controlling (409) one or more light sources to render the light effects. The light effects are determined based on the information relating to the video content in dependence on the video weight and based on the information relating to the audio content in dependence on the audio weight.
