Video Conference Stream Playback Using Buffered Prior Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During video conferencing, there is a need to playback previously shared content without disrupting the conference progress, especially when the sharer is interrupted, affecting the presentation and viewer experience.
Innovation Solution
A method and apparatus for displaying a video stream with a to-be-played-back video frame, allowing viewers to playback previous content seamlessly by identifying and managing such frames based on control operations, preset identifiers, or direct instruction, ensuring security and flexibility in display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the sharer is interrupted during presentation and asked to resend previously shared content, then the viewer can playback previous content, but the presentation idea of the sharer is affected, participation experience of users at other receive ends is affected, and overall progress of the video conference is affected
Solution Approach 1:
The system performs preliminary actions by buffering and storing previously shared video frames at the receive end before they are needed for playback. This allows the viewer to access previous content immediately without interrupting the current presentation flow or requiring the sharer to resend content, thus maintaining both information availability and conference productivity.
Solution Approach 2:
The system introduces an intermediary mechanism (buffering storage at the receive end) that decouples the viewer's need for previous content from the sharer's current presentation flow. This intermediary allows the viewer to playback previous frames independently without affecting the sharer's presentation progress or requiring interruption of the current video stream.
2Reliability
If the viewer plays back previous content during the video conference, then the display effect is improved, but the conference progress is affected
Solution Approach 1:
The system pre-buffers and stores previous video frames at the receive end during the presentation, so that when the viewer needs to playback previous content, the frames are already available for immediate display. This eliminates the need to pause or interrupt the current conference flow, maintaining both reliable display of previous content and continuous conference progress.
3Measurement precision
If the to-be-played-back video frame is obtained through active control operation, then the accuracy is improved, but the operation complexity is increased
Solution Approach 1:
The system implements self-service by automatically identifying and managing to-be-played-back video frames based on preset criteria (such as frame probability thresholds or identifiers) without requiring complex manual control operations from the user. The system serves itself by autonomously determining which frames need playback, thereby maintaining high accuracy while simplifying user interaction.

AI summary
This application discloses a video stream display method and apparatus, a device, a system, and a storage medium, and relates to the field of communication technologies. For example, a first device performs the method. The first device receives a video stream of a video conference sent by a second device. The first device displays the video stream on a first interface of the video conference. The first device obtains a to-be-played-back video frame corresponding to the video stream, and displays the to-be-played-back video frame on a second interface of the video conference. The to-be-played-back video frame is a video frame with a playback probability greater than a probability threshold in the video stream. The method enables a viewer to play back previous content at any time during the video conference without affecting progress of the video conference, thereby improving display effect of the video stream of the video conference.
