Virtual Relocation in Network Conferences via Background Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network conferences often fail to effectively convey the content and emotion of underlying events, as participants' video streams are displayed in separate boxes with different backgrounds, lacking a unified visual experience.
Innovation Solution
The method and apparatus for virtual relocation during a network conference, where the host device requests attendees to remove their backgrounds, generates a modified video stream, and relocates it within the host's background, allowing attendees to appear as if 'teleported' to the host's location, enhancing the unified visual experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual video boxes are used to display each participant, then network conference functionality is achieved, but unified visual experience and emotional expression are lost
Solution Approach 1:
The patent merges all individual participant video streams into a single unified background scene, replacing the traditional multiple separate video boxes. This allows all participants to be visually integrated into one cohesive environment, enhancing the unified visual experience while maintaining conference functionality.
Solution Approach 2:
The system creates a virtual copy of the background environment and composites multiple participant video streams onto it. This copying approach allows participants to appear as if they are physically present in the same location, achieving emotional expression and visual unity without requiring physical relocation.
2Manufacturing precision
If background removal is performed on attendee video streams, then virtual relocation accuracy is improved, but network bandwidth requirements increase
Solution Approach 1:
The patent segments the video processing into two distinct parts: background removal performed locally at each attendee's device, and background composition performed at the host device. This segmentation allows precise background removal without requiring continuous transmission of processed video data, reducing network bandwidth consumption while maintaining relocation accuracy.
Solution Approach 2:
The system introduces an intermediary instruction mechanism where the host sends background removal instructions to attendees, who then process their own video streams locally. This intermediary approach eliminates the need for the host to receive and re-process all video streams, significantly reducing network bandwidth requirements while achieving precise background removal for accurate virtual relocation.

AI summary
Methods and apparatus for receiving virtual relocation during a network conference. In an embodiment, a method is provided for relocating a conference participant during a network conference. The method includes receiving a first video stream having a first background, transmitting a second video stream, and receiving a request to remove a background from the second video stream. The method also includes removing the background from the second video stream to generate a modified video stream and transmitting the modified video stream. The method also includes receiving an instruction for relocating the modified video stream within the first background and relocating the modified video stream within the first background based on the instruction.
