Freeze-Frame Video Transition Control for Seamless Live Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transitioning from a freeze frame video to a live video in video communication sessions can cause visual disruptions due to noticeable changes in the local scene, such as changes in background or foreground, which can distract other participants.
Innovation Solution
A communication device and VCS host device implement a freeze frame video transition module that detects visually disruptive changes in the live video and modifies the live video to retain consistent visual characteristics with the freeze frame video, minimizing disruptions during the transition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the local participant transitions from presenting a freeze frame video to presenting a live video feed, then the video communication session resumes normal live transmission, but visual disruptions occur due to noticeable changes in the local scene
Solution Approach 1:
The system performs preliminary detection of visual changes in the live video feed before the actual transition from freeze frame to live video. By identifying potential disruptions in advance, the system can prepare mitigation strategies such as selecting alternative freeze frame moments or adjusting transition timing, thereby preventing visual disruptions before they occur to other participants.
Solution Approach 2:
The system continuously monitors the live video feed for visual changes and uses this feedback to determine whether transitioning to live video would cause disruptions. Based on the detected changes, the system provides feedback to control whether the transition should proceed or be delayed, ensuring smooth video communication without noticeable scene changes to other participants.
2Adaptability or versatility
If the local participant presents a freeze frame video to avoid advertising temporary absence, then the participant's engagement appears maintained, but visual disruptions occur when transitioning back to live video
Solution Approach 1:
Before transitioning from freeze frame to live video, the system preliminarily analyzes the current live video feed for visual changes. This advance detection allows the system to prepare appropriate transition strategies, such as selecting a different freeze frame moment that better matches the current scene or delaying the transition until visual changes are minimized, thereby maintaining video presentation flexibility while preventing disruptions.
Solution Approach 2:
The system uses real-time feedback from visual change detection in the live video feed to control the transition process. Based on the detected changes, the system dynamically adjusts transition timing and selects appropriate freeze frame moments, providing adaptive control that maintains both video presentation flexibility and visual consistency for other participants.
3Productivity
If the system transitions directly from freeze frame video to live video, then the transition process is simple and quick, but noticeable changes in the local scene create visual distractions for other participants
Solution Approach 1:
The system performs preliminary detection of visual changes in the live video feed before initiating the transition. This advance analysis identifies whether the transition will cause noticeable scene changes, allowing the system to quickly make a decision about transition timing or freeze frame selection, thereby maintaining fast transition speed while preventing visual distractions.
Solution Approach 2:
The system uses real-time feedback from visual change detection to control the transition process. Based on the detected changes, the system dynamically adjusts transition timing and freeze frame selection, providing rapid adaptive control that maintains high transition speed while eliminating visual distractions for other participants.

AI summary
A method provides non-disruptive transition from a freeze frame video back to a live video feed from a first communication device connected via a server device to a video communication session with other participants. The method includes presenting, by the server device, a freeze frame video including an image of a participant with a background. The method includes receiving live video of a field of view of an image capturing device of the first communication device, and detecting a change in a visual characteristic of the live video that can present a visual distraction to other participants. The method includes, in response to detecting the change: modifying aspects of the live video to provide a modified live video that retains the visual characteristic consistent with the freeze frame video; and presenting the modified live video to the video communication session on transition from freeze frame video to live video.
