Video Conference Interlinking With Split Video and Single-Stream Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video conference systems face limitations and errors when interlinking multiple systems, including restricted video sharing of non-active speakers, video quality issues, and voice echo problems.
Innovation Solution
A method and apparatus for interlinking video conference systems using primary and secondary video sharing units to transmit active speaker video and voice data separately, while muting non-active speakers, thereby preventing voice repetition and improving video quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If only the video of an active speaker is shared when interlinking video conference systems, then traffic is reduced, but participants cannot see videos of other participants in other conference systems
Solution Approach 1:
The patent segments video transmission into two distinct streams: active speaker video transmitted to all participants, and additional participant videos transmitted only to their respective conference systems. This segmentation allows selective distribution of video content, reducing unnecessary traffic while ensuring participants can access videos of other participants within their own conference system.
Solution Approach 2:
The patent applies local quality by providing different video content to different conference systems based on their specific needs. Each conference system receives videos of participants from its own system, creating a localized viewing experience tailored to each system's participants rather than uniformly transmitting all videos to all systems.
2Loss of information
If videos of multiple participants are arranged in a divided area, then multiple videos can be shared, but the size and quality of each video deteriorates
Solution Approach 1:
The patent segments the video distribution architecture into primary and secondary video sharing units. The primary unit handles active speaker video, while secondary units handle additional participant videos. This segmentation allows each unit to transmit videos at full resolution without compression from dividing limited screen space, maintaining video quality while enabling multiple video streams.
3Loss of information
If voice data of multiple users is transmitted through multiple video sharing units, then all voices are shared, but echo and voice errors occur
Solution Approach 1:
The patent merges voice transmission into a single consolidated stream through the primary video sharing unit. All voice data from multiple users is combined and transmitted through one unit, preventing the echo and voice errors that occur when multiple units independently transmit voice data. Video data continues to be distributed through multiple units, maintaining video sharing capability while eliminating voice-related harmful effects.
4Adaptability or versatility
If a plurality of video conferences is interlinked between multiple conference systems, then conferencing flexibility increases, but video and voice errors such as echo occur
Solution Approach 1:
The patent segments the interlinking architecture into primary and secondary video sharing units with distinct functional roles. This segmentation enables multiple conference systems to interlink flexibly while maintaining reliable video and voice transmission by preventing conflicting data streams from causing errors.
Solution Approach 2:
The patent introduces the primary video sharing unit as an intermediary that consolidates voice data transmission. This intermediary role prevents direct voice data exchange between multiple conference systems that would cause echo, while still enabling flexible interlinking through coordinated video data transmission via secondary units.
