Multi-Camera Replay System with Automatic Timing Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current instant replay systems for live events, such as sports, are labor-intensive and require multiple technicians to synchronize and review video recordings from multiple cameras, making it difficult for officials to determine the relative timing of key incidents.
Innovation Solution
A video recording and replay system that automatically synchronizes frame timing information across multiple cameras, allowing officials to flag incidents and display relative timing intervals, enabling synchronized playback and marking of key events with flags set by observers or automated systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple technicians manually synchronize and review video recordings from multiple cameras, then the accuracy of determining relative timing of incidents is improved, but the labor intensity and time required for review increase significantly
Solution Approach 1:
The system automatically performs the synchronization and timing determination functions that previously required multiple technicians. The computer system self-services by ingesting timecode data from multiple cameras, automatically synchronizing the recordings, and determining the relative timing of incidents without human intervention in the manual synchronization process.
Solution Approach 2:
The manual mechanical process of technicians coordinating and synchronizing video recordings is replaced by an automated electronic system. The computer system uses digital timecode data and automated algorithms to perform the synchronization function that previously required human operators to manually coordinate multiple video feeds.
2Measurement precision
If technicians manually determine the order of occurrence of key incidents from multiple recordings, then the accuracy of incident sequencing is improved, but the time required for review increases
Solution Approach 1:
The system performs preliminary synchronization of all video recordings using timecode data before the actual incident review process. By pre-synchronizing the recordings and establishing the temporal relationships between different camera feeds, the system eliminates the time-consuming manual sequencing process during the actual incident review.
Solution Approach 2:
The system introduces an intermediary computational process that automatically determines the order of incidents by comparing timecode data from multiple cameras. This intermediary automated analysis layer sits between the raw video recordings and the officials' review process, providing pre-processed timing information that speeds up the decision-making process.
3Reliability
If multiple full-time technicians are dedicated to feeding video recordings to officials, then the completeness of incident review is improved, but the operational cost and complexity increase
Solution Approach 1:
The automated computer system performs multiple functions that previously required separate technicians: synchronizing recordings, determining timing, sequencing incidents, and presenting information to officials. This multi-functional system consolidates the roles of multiple specialized technicians into a single integrated automated platform.
Solution Approach 2:
The system creates automated copies and presentations of video segments from multiple cameras, allowing officials to review synchronized footage without requiring technicians to manually prepare and switch between different video feeds. The automated system generates the necessary video presentations and timing information for complete incident review.
Data Source
AI summary
A system is disclosed for the replay of multiple simultaneously recorded recordings of live events. Flags are used to map the time of occurrence of incidents observed on one video recording onto second simultaneously obtained recording where they can be observed. The proper phasing of mapped incidents and incidents that are explicitly visible on the second recording is maintained.
