Video Conference Layout Cropping for Portrait Participant Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video conference platforms inefficiently transmit and display landscape-oriented video streams, leading to increased computing resource consumption, latency, and loss of nonverbal cues due to inconsistent and suboptimal display of participant video streams.
Innovation Solution
Implementing a video conference manager that processes and crops video streams based on identified visual features, such as facial and body features, to determine optimal display modes like portrait or landscape orientation, aligning eyelines and head sizes, and generating a rendered composition for efficient display.

Engineering Contradiction Analysis
1Area of stationary object
If landscape-oriented video streams are transmitted and displayed in conventional video conference platforms, then the display area for each participant is maximized, but computing resource consumption increases and latency increases
Solution Approach 1:
The video stream is segmented by cropping it to display only the relevant portion (e.g., portrait-oriented region) instead of transmitting and displaying the entire landscape-oriented stream. This reduces the amount of data that needs to be processed and displayed, thereby reducing computing resource consumption while maintaining adequate display area for the participant.
2Area of stationary object
If landscape-oriented video streams are transmitted and displayed in conventional video conference platforms, then the display area for each participant is maximized, but latency increases
Solution Approach 1:
By cropping the video stream to portrait orientation, the system reduces the amount of video data that needs to be transmitted and rendered. This segmentation of the video content reduces processing time and transmission bandwidth requirements, thereby decreasing latency while preserving sufficient display area for participant visibility.
3Area of stationary object
If landscape-oriented video streams are displayed in conventional video conference platforms, then space utilization is reduced, but computing resource consumption increases
Solution Approach 1:
Instead of displaying the entire landscape-oriented video stream and wasting space, the system inverts the approach by cropping the stream to portrait orientation. This inversion allows the displayed content to better fit the available space on client devices, improving space utilization while simultaneously reducing the computing resources needed to process and display the video.

AI summary
Systems and methods for determining whether to display video conference participants in first display mode are provided. A plurality of video streams from a plurality of client devices of a plurality of participants of a video conference are received. One or more visual features of one or more objects in each of the plurality of video streams is identified. Based on the identified one or more visual features, a determination is made whether to use a first display mode or a second display mode for one or more visual items of a plurality of visual items corresponding to the plurality of video streams in a rendered composition. The rendered composition of the plurality of visual items is caused to be displayed in a user interface of a client device of the plurality of client devices in accordance to the determined first display mode or second display mode.
