Composite Video Superimposition for Group Conference Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video communication techniques fail to optimize the limited video view by equally presenting each location in a group setting, leading to a disadvantageous focus on recent or frequent speakers, which does not allow for a continuous view of all users, including those who have not spoken.
Innovation Solution
The system determines peers in a video communication, analyzes their video streams to identify users and static locations, modifies the image content of secondary peers by changing shapes, resizing, and removing background or foreground, and superimposes modified video streams onto primary peers to create a composite video that accommodates all participants, ensuring a tailored and seamless view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video streams of all peers are equally presented in a group video communication, then all users can be continuously displayed, but the limited video view cannot accommodate all participants effectively
Solution Approach 1:
The system segments the video communication participants into primary peers and secondary peers. Primary peers occupy the main video view area while secondary peers are integrated through superimposition. This segmentation allows all participants to be visible simultaneously by allocating different spatial roles, resolving the contradiction between showing all users and maintaining adequate video quality within limited view area.
Solution Approach 2:
The system embeds video streams of secondary peers within the video stream of primary peers through superimposition. The modified video stream of a secondary peer is nested onto the primary peer's video stream, creating a composite video where multiple participants coexist in a hierarchical spatial arrangement. This nesting enables continuous display of all participants without requiring equal display area for each.
2Loss of information
If the video stream of a secondary peer is superimposed onto the primary peer, then all participants can be displayed simultaneously, but the image quality and clarity may be compromised
Solution Approach 1:
The system extracts specific image content from the secondary peer's video stream (such as background or non-essential foreground elements) before superimposition. By removing certain portions of the secondary peer's video content, the system reduces visual conflict and maintains better overall image quality while still achieving simultaneous display of all participants.
Solution Approach 2:
The system applies different processing treatments to different regions of the composite video. The primary peer's video stream maintains full quality in its primary display area, while the superimposed secondary peer content is selectively modified. This local differentiation of quality ensures that critical visual information remains clear while still achieving comprehensive participant visibility.
3Ease of operation
If conventional video communication equally presents each location, then all users are visible, but the focus defaults to recent or frequent speakers rather than maintaining continuous view of all users
Solution Approach 1:
The system performs preliminary classification of peers into primary and secondary categories before the video communication begins or during setup. This pre-established hierarchy enables automatic focus management throughout the communication, eliminating the need for dynamic adjustments based on speaking activity. The primary peer maintains continuous visibility as the base layer, ensuring all participants remain visible without defaulting to speaker-focused views.

AI summary
Systems, methods, and non-transitory computer readable media are configured for determining that a first peer involved in a video conference is a primary peer; determining that a second peer involved in the video conference is a secondary peer in response to non-satisfaction by the second peer of a threshold associated with a selected number of objects in the second peer; determining a viewing peer involved in the video conference, wherein the primary peer, the secondary peer, and the viewing peer are different; creating a modified video stream of the second peer in response to the determining that the second peer is the secondary peer based on the non-satisfaction by the second peer of the threshold associated with the selected number of objects in the second peer; detecting a static area and a dynamic area in a video stream of the first peer; superimposing the modified video stream of the second peer onto the static area in the video stream of the first peer; and providing a composite video including the video stream of the first peer, the modified video stream of the second peer, and a video stream of the viewing peer for presentation to the viewing peer.
