Dynamic Video Link Quality Transition for Spontaneous Collaboration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication and collaboration tools at a distance are often impersonal, require significant coordination, and lack spontaneity, with always-on video links posing security and resource usage issues.
Innovation Solution
A portal engine maintains an always-on, bi-directional video link with a digital whiteboard for enhanced communication and collaboration, transitioning from reduced-quality to high-quality video upon user activation, while preserving privacy and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an always-on high-quality video link is maintained between two locations, then real-time communication and spontaneity are improved, but resource consumption and security risks increase
Solution Approach 1:
The system dynamically adjusts video quality between dormant and active states based on user interaction. When no interaction occurs, video is rendered at reduced quality to conserve resources. Upon user interaction (clicking or touching the display surface), the video transitions to high quality for active communication. This dynamic adjustment resolves the contradiction by providing high-quality video only when needed while maintaining the always-on connection for spontaneity.
Solution Approach 2:
The patent applies different quality levels to different states of the same video stream. The dormant state uses reduced-quality rendering with limited bandwidth, while the active state uses high-quality rendering with full bandwidth. This local quality differentiation allows the system to optimize resource consumption during idle periods while ensuring high communication quality when users actually interact, resolving the resource consumption vs. communication quality tradeoff.
2Ease of operation
If an always-on video link is maintained between two locations, then real-time communication capability is improved, but security and privacy concerns worsen
Solution Approach 1:
The system dynamically changes video rendering quality based on interaction state. During dormant periods, reduced-quality rendering with obscured or blurred video content maintains the connection while minimizing security and privacy exposure. When users actively interact with the display surface, full-quality video is restored for clear communication. This dynamic quality adjustment resolves the contradiction by maintaining real-time communication capability while reducing security and privacy risks during idle periods.
3Productivity
If traditional video conferencing systems are used, then communication functionality is achieved, but coordination effort and equipment requirements increase
Solution Approach 1:
The patent merges the video conferencing functionality directly into the display surface itself, eliminating the need for separate video conferencing equipment and coordination protocols. The display surface becomes both the interface for user interaction and the medium for video communication. This merging resolves the contradiction by providing full communication functionality while dramatically reducing device complexity and coordination requirements, as the display surface handles both functions natively.

AI summary
Technology is disclosed herein that enhances communication and collaboration at a distance. In an implementation, a portal engine provides a communication and content portal through which users situated in different locations may interact and collaborate with each other. The portal includes an always-on, bi-directional video link through which the users may communicate over video. The portal may also include a digital white-board or other surface link over which shared content may be exchanged.
