Dynamic Aspect Ratio Control for Video Communication Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems fail to optimally display multiple video streams, leading to reduced user engagement and inefficient use of computing resources due to uniform aspect ratios that do not differentiate between single and multi-person videos, resulting in missed social cues and increased resource usage.
Innovation Solution
Implementing dynamically controlled aspect ratios based on the number of individuals in each video stream, where streams with a threshold number of people use a wider aspect ratio and those with fewer individuals use a narrower aspect ratio, improving visibility and resource efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform aspect ratios are used for all video streams, then device complexity is reduced and ease of operation is improved, but user engagement deteriorates and manufacturing precision of visual presentation is compromised
Solution Approach 1:
The patent applies local quality by assigning different aspect ratios to different video streams based on their content characteristics. Specifically, multi-person video streams are displayed with a first aspect ratio (e.g., 16:9) while single-person streams use a second aspect ratio (e.g., 4:3). This allows each video stream to have optimized display proportions tailored to its specific content type, improving visual presentation quality without requiring complex manual configuration.
2Device complexity
If equal size arrangements are used for all video streams, then device complexity is reduced, but user engagement deteriorates due to reduced visibility of social cues
Solution Approach 1:
The patent implements local quality by creating distinct display configurations for different video stream types. Multi-person streams are rendered with aspect ratios optimized for group visibility, while single-person streams use aspect ratios that maximize individual participant visibility. This automatic differentiation improves user engagement and reliability of social cue detection without adding significant device complexity, as the system autonomously determines appropriate aspect ratios based on content analysis.
3Reliability
If manual interaction is required to compensate for poor display arrangements, then user engagement can be maintained, but productivity deteriorates and use of energy increases
Solution Approach 1:
The patent applies self-service by enabling the communication system to automatically analyze video stream content and determine appropriate aspect ratios without user intervention. The system autonomously identifies whether a video stream contains multiple people or a single person and applies the corresponding aspect ratio configuration. This eliminates the need for manual adjustments, maintaining user engagement while improving productivity and reducing energy consumption associated with manual interactions.
4Loss of information
If follow-up meetings are scheduled to address missed content, then information completeness is improved, but loss of time increases and use of energy increases
Solution Approach 1:
The patent implements preliminary action by ensuring that all participants are properly visible and identifiable from the outset through optimized aspect ratio display arrangements. By pre-configuring appropriate aspect ratios for different video stream types, the system prevents information loss during the initial communication session, eliminating the need for follow-up meetings to address missed content or identify participants. This reduces both time loss and energy consumption associated with scheduling and conducting additional meetings.

AI summary
The disclosed techniques improve user engagement and more efficient use of computing resources by providing dynamically controlled aspect ratios for communication session renderings based on a number of people depicted in shared video streams. A system can identify select streams depicting at least a threshold number of individuals. A first aspect ratio can be selected from a number of preset aspect ratios for the display of select streams depicting at least the threshold number of individuals. A second aspect ratio can be selected for the display of other individual streams having video components depicting less than the threshold number of individuals. In some embodiments, the first aspect ratio is greater than the second aspect ratio. By switching between aspect ratios depending on a number of individuals depicted in each video stream, a system can improve user engagement by equalizing the display each person participating in a communication session.
