Dynamic Video Compression via Human Factors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for delivering digital video content over bandwidth-constrained media often rely on a single compression level, failing to account for the varying desirability of content, which affects viewer satisfaction and network efficiency.
Innovation Solution
A system that collects human-factors data on content desirability to dynamically adjust compression levels, ensuring higher compression for less desirable content and lower compression for more desirable content, optimizing bandwidth usage based on viewer preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a single compression level is used for all content, then network load is minimized, but viewer satisfaction cannot be optimized for different content types
Solution Approach 1:
The system dynamically adjusts compression levels based on content characteristics and viewer preferences rather than using a fixed single compression level. The compression level is continuously adapted according to the desirability score of content, allowing optimal balance between network efficiency and viewer satisfaction for each specific content item.
Solution Approach 2:
The invention changes the compression parameter dynamically based on content desirability scores. Content with higher desirability scores receives lower compression ratios to maintain quality, while content with lower desirability scores receives higher compression ratios to reduce network load, thus optimizing both network efficiency and viewer satisfaction across different content types.
2Productivity
If higher compression is applied to minimize network load, then bandwidth efficiency improves, but video quality deteriorates
Solution Approach 1:
The system applies different compression qualities to different content items based on their desirability scores. High-desirability content maintains high video quality with lower compression, while low-desirability content accepts lower quality with higher compression. This local differentiation of quality levels optimizes overall bandwidth efficiency without uniformly sacrificing quality across all content.
Solution Approach 2:
The compression ratio parameter is dynamically changed based on content desirability. The system adjusts the compression level as a variable parameter, assigning lower compression ratios to high-desirability content to preserve quality and higher compression ratios to low-desirability content to maximize bandwidth efficiency, thus resolving the contradiction between quality and efficiency.
3Adaptability or versatility
If compression level is adjusted for each content item, then viewer satisfaction is optimized, but system complexity increases
Solution Approach 1:
The system uses feedback from viewer preference data and content characteristics to automatically adjust compression levels. By incorporating feedback mechanisms that analyze viewer behavior and content attributes, the system can autonomously determine optimal compression ratios without requiring complex manual configuration or user input, thus managing complexity through automated feedback-driven adaptation.
Solution Approach 2:
The compression system performs self-adjustment based on automatically collected data about content desirability and viewer preferences. Rather than requiring external intervention or complex user configuration, the system serves itself by using built-in data collection and analysis capabilities to autonomously optimize compression levels for each content item, reducing operational complexity while maintaining high adaptability.
4Productivity
If content desirability data is collected and used for compression adjustment, then compression optimization is achieved, but data collection and processing requirements increase
Solution Approach 1:
The system collects and processes viewer preference data automatically as part of its normal operation, using self-service mechanisms to gather data from viewing behavior patterns and content characteristics. This automated data collection and processing eliminates the need for separate complex data gathering systems, reducing overall system complexity while still achieving comprehensive compression optimization based on content desirability.

AI summary
Methods, systems and content have been developed for increasing the bandwidth available to a bandwidth-constrained medium for transmitting digital video content. The content that is to be transmitted is compressed in proportion to the desirability of the content. The desirability of the content is determined by obtaining human-factors data indicative of whether a selected item of content is highly desirable. A desirability score derived from the data is assigned to the content. The desirability score determines the compression level. Feedback systems change the level of compression as the desirability of the content changes with time.
