Video Stream Frame Correction for Unstable Network Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video streaming systems face issues with unstable network conditions, leading to lost or delayed frames, which result in a jumpy and inconsistent viewing experience due to freezing or interrupting the video stream.
Innovation Solution
The system detects transmission interruptions by analyzing frame timestamps and inserts correction frames, including repetitions and interpolations, to maintain a stable output video stream without freezing or interrupting the presentation, thereby reducing the visibility of transmission issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional video streaming systems freeze or interrupt the video stream to handle lost frames, then transmission stability is improved, but viewing smoothness deteriorates
Solution Approach 1:
The system performs preliminary actions by detecting lost frames through timestamp analysis and proactively inserting correction frames (repetition or interpolation) before the video stream would naturally freeze or interrupt. This preventive approach maintains both transmission reliability and viewing smoothness simultaneously.
2Duration of action of moving object
If correction frames are inserted to maintain continuous playback, then viewing smoothness is improved, but transmission reliability deteriorates
Solution Approach 1:
The system introduces correction frames as intermediary elements between the original video frames. These correction frames (either repetitions or interpolations) act as mediators that bridge gaps caused by lost frames, maintaining both viewing smoothness and transmission reliability by providing a seamless transition.
3Reliability
If placeholder images or videos are inserted to indicate transmission issues, then transmission reliability is improved, but user experience deteriorates
Solution Approach 1:
The system converts the harmful effect of transmission interruptions into a beneficial outcome by using lost frame detection as an opportunity to insert correction frames. Instead of displaying annoying placeholders that alert users to problems, the system silently corrects the issues and maintains smooth playback, turning a potential negative experience into a seamless viewing process.

AI summary
Techniques for output frame correction for unstable video streams are described herein. A video item may be transmitted via an input video stream from a first entity to a second entity over one or more electronic communications networks. The incoming frames from the input video stream may then be used, by the second entity, to generate an output video stream for presentation to one or more viewers. The transmission of the input video stream may temporarily become unstable and may be interrupted such that one or more frames of the input video stream are delayed and/or lost. When a transmission interruption is detected, the output video stream may be adjusted by inserting one or more correction frames into the output video stream. The inserted correction frames may include one or more repetitions of one or more prior frames in the output video stream and/or one or more interpolated frames.
