Multi-Video Synchronization via Reference Time Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in synchronizing and viewing multiple independent video recordings captured from different locations or viewpoints, as existing systems struggle to align and play back these videos simultaneously in a coherent manner.
Innovation Solution
A method and system for integrating multiple independent video recordings by receiving metadata with reference times, selecting videos for playback, and synchronizing them into a common timeline within a single user interface, allowing for simultaneous playback of videos recorded on different devices not directly networked together, with options for dynamic addition or removal of videos based on time overlap and audio management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent video recordings from different devices are synchronized and integrated into a common timeline, then the ability to compare and contrast events from various perspectives is improved, but the device complexity and synchronization difficulty increase
Solution Approach 1:
The patent introduces a central server as an intermediary that receives videos from multiple independent devices, processes their metadata, and manages synchronization. This mediator handles the complex coordination between devices that are not directly networked together, reducing the complexity burden on individual devices while enabling versatile multi-perspective video comparison
2Adaptability or versatility
If videos from devices not directly networked together are integrated, then the versatility of video sources is improved, but the synchronization reliability decreases
Solution Approach 1:
The system performs preliminary actions by extracting and processing metadata (including timestamps, GPS coordinates, and event information) from each video before integration. This pre-processing of synchronization data from independent devices establishes a common reference framework in advance, enabling reliable synchronization even when devices are not directly networked together during playback
3Ease of operation
If multiple videos are played back simultaneously in a single user interface, then the user experience is improved, but the interface complexity increases
Solution Approach 1:
The user interface segments the playback of multiple videos by displaying them in separate regions or panels within the single interface. Each video can be controlled and viewed independently in its own segment, while the overall interface maintains a unified timeline for synchronization. This segmentation approach improves ease of operation by allowing independent video control while managing interface complexity through organized spatial separation

AI summary
For integrating multiple independent video recordings, method is disclosed. The method includes a receiving a plurality of videos from a plurality of sources. The method also includes receiving metadata for the plurality of videos, the metadata comprising a reference time for each of the plurality of videos. The method includes selecting for playback a first video and a second video, wherein the first video and the second video were recorded on different devices not directly networked together. The method further includes synchronizing playback of the first video and the second video in a single user interface, wherein synchronizing playback of the first video and the second video comprises integrating the first video and the second video into a common timeline based at least in part on the metadata of each of the first video and the second video.
