Adaptive Video Encoding for Display Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video displays with varying capabilities and ambient conditions can alter the perception of video content, deviating from the creator's intent, necessitating methods to adapt video playback to preserve the intended appearance across different devices and environments.
Innovation Solution
The solution involves packaging multiple versions of video content optimized for different displays and ambient conditions, using a data processing stage to interpolate or extrapolate between these versions, and a media server to select and generate optimized content based on the destination display's capabilities and ambient conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If video content is created optimized for high-performance displays, then the creative intent can be fully realized on advanced displays, but the content appears degraded or different on legacy displays with lower capabilities
Solution Approach 1:
The video content is segmented into multiple versions, each optimized for different display capabilities. The system divides the single video file into alternative representations that can be selectively delivered based on the destination display's characteristics, resolving the contradiction between optimization for high-performance displays and compatibility with legacy displays
Solution Approach 2:
The system dynamically selects and delivers the appropriate video version based on real-time detection of the destination display's capabilities. This dynamic adaptation allows the same video content to be optimally presented across varying display technologies, from legacy to high-performance displays
2Ease of operation
If video content is delivered in a single standardized format, then distribution is simplified, but the content cannot take advantage of improved display capabilities or adapt to different viewing environments
Solution Approach 1:
The video delivery system is designed with multi-functionality to handle both simple standardized distribution and complex adaptive delivery. The system can operate in different modes depending on the requirements, providing universal compatibility across various distribution scenarios while maintaining the ability to optimize for specific display capabilities when needed
3Ease of manufacture
If video content is created without considering ambient conditions, then the production process is simpler, but the perceived color and luminance significantly differ when viewed in different ambient light conditions
Solution Approach 1:
The system performs preliminary encoding of video content in multiple versions optimized for different ambient light conditions before delivery. By pre-adapting the content to various viewing environments, the system ensures consistent perception across different settings without requiring complex real-time adjustments during playback
Data Source
AI summary
Methods and apparatus for distributing video data provide video data containing two or more different versions of video content. The different versions may be optimized for display on different displays and/or for viewing under different ambient conditions. Video data optimized for display on a particular display under particular ambient conditions may be obtained by one or more of selecting one of the versions of video content and combining two or more of the versions of the video content.
