Composite Video Stream Reframing for Unified Speaker and Content Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video conference platforms require participants to follow two separate video streams for viewing a speaker and shared digital content, which can be inefficient and resource-intensive.
Innovation Solution
A composite video stream is generated that integrates digital content with participant video by cropping, reframing, and compositing layers to create a unified video output, allowing seamless presentation of both within a single region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate video streams are used for speaker and digital content, then participants can view both, but the system becomes resource-intensive and inefficient
Solution Approach 1:
The patent merges the speaker video stream and digital content into a single composite video stream. The system composites the speaker's video feed with digital content (such as slides or documents) into one unified stream, eliminating the need for participants to switch between or follow separate streams. This reduces processing resource consumption and improves overall system efficiency.
Solution Approach 2:
The composite video stream serves multiple functions simultaneously - it displays both the speaker and the digital content in a single stream. This multi-functional approach allows the system to replace what would traditionally require two separate video streams, reducing the computational burden on the system while maintaining comprehensive information delivery.
2Ease of operation
If separate video streams are used for speaker and digital content, then both can be displayed, but participants must follow multiple streams
Solution Approach 1:
The system combines multiple video streams into a single composite stream that simultaneously presents both the speaker and digital content. This eliminates the complexity of managing and switching between multiple streams, simplifying the participant experience while maintaining all necessary visual information in one unified feed.
3Stability of the object's composition
If digital content is overlaid on participant video, then integration is improved, but visual clarity and contrast may be compromised
Solution Approach 1:
The system applies different processing characteristics to different regions of the composite video stream. The speaker's video feed maintains its original quality and contrast in certain regions, while digital content is overlaid in specific areas. This localized quality maintenance ensures that both the speaker and content remain visually distinct and clear, preventing degradation of visual contrast while achieving integration.

AI summary
A first event associated with a first client device of multiple client devices of participants of a video conference is identified. The first event indicates a request to present content in a user interface (UI) including regions each corresponding to one of multiple video streams from the client devices. A first video layer that includes a reframed visual representation of the first participant is generated from the first video segment of a first video stream from the first client device. A first content layer is generated. The first video layer and the first content layer are composited into the first composite video segment in which the reframed visual representation of the first participant is positioned adjacent to the first part of the content. The first composite video segment is provided to the client devices as a real-time video stream for presentation.
