Video Conference Image Layout Adaptation Across Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video conferencing systems, particularly telepresence systems, face challenges in interoperability between different manufacturers and configurations, such as varying numbers of screens and cameras, leading to suboptimal participant presence and image quality when multiple systems with different setups are connected.
Innovation Solution
A method for processing images in video conferencing involves determining properties of connected terminals, grouping them, and mapping these groups to specific pane layouts to create a composite image stream, ensuring consistent and undistorted presentation across diverse terminal configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If telepresence systems use proprietary protocols and fixed screen configurations, then image quality and presence feeling are improved for compatible systems, but interoperability between different manufacturers and configurations deteriorates
Solution Approach 1:
The system dynamically adapts the pane layout based on the actual configuration of connected terminals. Instead of using fixed proprietary layouts, the system determines properties of connected terminals, defines groups based on these properties, and dynamically generates appropriate pane layouts for each terminal type, enabling both high-quality telepresence experiences and broad interoperability
Solution Approach 2:
The system changes the layout parameters (number of panes, their arrangement, mapping to terminal screens) based on the detected terminal properties. By adjusting these parameters dynamically according to the connected terminals' capabilities, the system maintains optimal image quality for each configuration while ensuring compatibility across different manufacturers and screen setups
2Adaptability or versatility
If different numbers of screens are used in telepresence terminals, then system flexibility and adaptability are improved, but consistent image presentation and presence feeling across all terminals deteriorate
Solution Approach 1:
The system applies different pane layouts tailored to each terminal's specific screen configuration. Each terminal receives a customized layout that optimizes the presentation for its local capabilities, ensuring that image quality and presence feeling are maintained appropriately for each terminal type while allowing overall system flexibility
Solution Approach 2:
The pane layout determination is performed dynamically based on the actual terminal properties detected during the conference. This dynamic adaptation ensures that each terminal, regardless of its screen count, receives an optimized layout that maintains consistent image presentation quality across the diverse terminal fleet
3Manufacturing precision
If proprietary protocols are used for telepresence systems, then presence feeling and image quality are improved for compatible systems, but ease of operation and accessibility to different manufacturers deteriorate
Solution Approach 1:
The system implements a universal pane layout determination mechanism that works across different terminal types and manufacturers. By determining properties of connected terminals and dynamically generating appropriate layouts, the system provides telepresence-quality experiences to all participants regardless of their specific terminal configuration, making the system easier to operate with diverse equipment

AI summary
Processing images in conference between a plurality of video conferencing terminal. The method includes providing properties of terminals, defining a number of groups based on the properties of the terminals, then determining an ordered list of the a number of groups, and determining a pane layout for displaying images from the terminals. The pane layout is determined based on the provided properties of the terminal the pane layout is displayed on and the properties of the other terminals in the conference. Then, mapping the ordered list of the number of groups to the respective determined pane layout, and providing at least one composite image stream to each of the terminals according to the selected pane layout and mapping of the a number of groups. Different types of telepresence endpoints, (e.g. different manufacturers, numbers of screens/cameras, etc.) can thus interoperate well in the same video conference.
