Ambient Light Control From Embedded Video Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content-presentation systems lack the ability to synchronize ambient lighting with video content, resulting in a less immersive viewing experience for end-users.
Innovation Solution
A method and system that extracts light control parameters from video content, separate from the visual appearance data, and transmits them to a light unit controller to synchronize ambient lighting with the video content, using existing communication channels or generating parameters based on video metadata.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light control parameters are extracted from video content, then lighting synchronization with video content is achieved, but data processing complexity increases
Solution Approach 1:
The patent extracts light control parameters from video content by separating them from the main video data stream. The system identifies and extracts specific parameter portions from received video content, isolating the lighting control instructions from the visual content data. This extraction approach enables independent processing of lighting parameters without affecting video playback, resolving the contradiction by pulling out only the necessary control data.
Solution Approach 2:
The video content data structure is segmented into distinct portions: visual content data and light control parameters. The system divides the incoming video stream to separate these elements, allowing the light control parameters to be processed independently through dedicated communication channels. This segmentation reduces processing complexity by handling lighting control as a separate task from video rendering.
2Reliability
If separate communication channel is used for light control parameters, then lighting control reliability is improved, but system complexity increases
Solution Approach 1:
The system utilizes existing communication interfaces and protocols to transmit both video content and light control parameters. Rather than creating entirely new communication hardware, the patent adapts existing channels and protocols to carry additional lighting control data, reducing system complexity while maintaining reliable control through multi-functional use of available communication infrastructure.
3Productivity
If light control parameters are embedded in video content, then data transmission efficiency is improved, but parameter extraction complexity increases
Solution Approach 1:
The light control parameters are prepared and embedded in the video content data stream in advance, during content production or preprocessing. This preliminary organization of data ensures that when the video content is transmitted and received, the parameters are already positioned for efficient extraction, reducing the complexity of real-time parameter identification and separation at the playback device.
Data Source
AI summary
In one aspect, a method includes receiving video content comprising a first data portion comprising parameters that control a visual appearance of frames of video content presented by a content-presentation device. The content-presentation device is communicatively coupled to a light unit that is (i) present in a viewing area of the content-presentation device and (ii) configured to provide ambient light in the viewing area. The method also includes extracting, from the received video content, a second data portion, separate from the first data portion, specifying one or more light control parameters that a controller associated with the light unit is configured to interpret as instructions for controlling the light unit. The method also includes transmitting the extracted second data portion to the controller to facilitate the controller controlling the light unit according to the specified one or more light control parameters.
