Environment Lighting Effects Synchronization in Video Presentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for providing environment lighting effects around video content items lack creative control, are inefficient, and do not effectively support live and streaming scenarios.
Innovation Solution
The implementation of devices and methods that synchronize environment lighting effects with video content items, allowing content creators to specify lighting parameters such as color, intensity, and spatial attributes, which can be stored and retrieved for playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If environment lighting effects are automatically determined from video content, then the system complexity is reduced, but creative control over lighting effects is lost
Solution Approach 1:
Lighting effect parameters are pre-defined and stored in a lookup table during content creation, allowing content creators to specify desired lighting effects in advance. During playback, the system automatically retrieves these pre-configured parameters based on content identifiers, combining automatic operation with creative control.
2Adaptability or versatility
If lighting effects are determined in real-time during playback, then adaptability to different content is improved, but processing time and efficiency decrease
Solution Approach 1:
All lighting effect parameters are pre-calculated and stored in a lookup table before playback. The system only performs fast retrieval operations during content delivery, avoiding time-consuming real-time analysis while maintaining adaptability to different content through content-specific parameter selection.
Solution Approach 2:
The system uses a lookup table that stores pre-computed lighting parameters as reusable templates. Instead of recalculating lighting effects for each playback instance, the system copies and applies the appropriate pre-defined parameters based on content identification, significantly improving processing efficiency.
3Manufacturing precision
If detailed environment parameter data is stored for each video content item, then lighting effect quality is improved, but storage requirements and system complexity increase
Solution Approach 1:
The system stores lighting parameters in a structured lookup table format that can be efficiently queried and applied. By organizing parameters as reusable templates with content identifiers, the system maintains high lighting quality through detailed parameters while reducing overall system complexity through standardized data structures and retrieval mechanisms.

AI summary
Various implementations present video content along with time-synchronized environment lighting effects (e.g., light-spill). The environment lighting effects are based on obtaining a stored environment parameter specifying the effects for different times during the video content (e.g., effects stored as a track/metadata of the content itself or effects stored in a separate lookup table). A content creator is enabled to specify, for their content item, the light-spill (color, intensity, saturation, brightness/nits, opacity, etc.) or other environment lighting effects, such as making a sun effect brighter using HDR. The ability to specify such effects may give those content creators and editors more control over the content-viewing experience. Predefined/stored effects may also facilitate using effects in the case of real-time streaming in which on-the-fly, automatic content-based effect determinations may be infeasible.
