Video Stream Stitching Helper for Unstitchable Conference Feeds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conferencing software often lacks the capability to stitch multiple video streams from different devices into a unified stream, particularly when one or more streams are unstitchable due to lack of identifiable features, thereby limiting situational and contextual awareness for conference participants.
Innovation Solution
The conferencing software obtains a stitching image from a secondary device, such as a mobile phone or tablet, to bridge the unstitchable stream with other streams, using features common to both, thereby enabling the creation of a unified video stream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conferencing software attempts to stitch multiple video streams into a unified stream, then situational and contextual awareness is improved, but the system fails when streams lack identifiable features for stitching
Solution Approach 1:
The patent introduces a stitching image as an intermediary element that mediates between the unstitchable video stream and the existing unified stream. This stitching image contains identifiable features that bridge the gap, allowing the conferencing software to successfully stitch previously unstitchable streams into the unified view, thereby improving both situational awareness and stitching reliability
2Measurement precision
If the system requires identifiable features in video streams for stitching, then stitching accuracy is improved, but streams without such features cannot be integrated
Solution Approach 1:
The stitching image serves as a mediator that provides the necessary identifiable features for accurate stitching. By introducing this intermediate element with known features, the system maintains high stitching accuracy while simultaneously increasing adaptability to accommodate streams that originally lacked sufficient features for stitching
Solution Approach 2:
The system performs preliminary capture of a stitching image containing identifiable features before the stitching process. This preliminary action ensures that when streams need to be stitched, accurate reference features are already available, enabling both precise stitching and broader integration capability
3Adaptability or versatility
If a secondary device is used to capture a stitching image, then stream integration is enabled, but device complexity increases
Solution Approach 1:
The patent leverages existing secondary devices (mobile phones, tablets) that participants already possess and use for conference access. By making these multi-functional devices serve the additional function of capturing stitching images, the system enables stream integration without adding dedicated hardware, thus minimizing increase in device complexity

AI summary
A first image of a first video stream and a second image of a second video stream are displayed at a device. The first video stream and the second video stream are video streams of a video conference. A stitching image is identified in preview images received from a camera of the device. The stitching image is transmitted to a conferencing software associated with the video conference.
