Game Event Indexing via Video Timestamp Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for recording and viewing sports game events are labor-intensive and time-consuming, requiring users to manually enter data while watching videos, which is inefficient for real-time monitoring and analysis.
Innovation Solution
A mobile application and server system that allows users to record and associate game actions with video footage in real-time, using mobile devices to indicate game actions and a server system to correlate this data with video timestamps, enabling efficient indexing and playback of specific game events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually enter game event data while watching videos, then data accuracy is improved, but time consumption and labor intensity increase significantly
Solution Approach 1:
The system enables spectators to automatically generate game event data by viewing the video themselves. The video player automatically detects and timestamps game events (goals, shots, cards) without requiring manual data entry, allowing users to both consume and contribute data simultaneously.
Solution Approach 2:
An intermediary system acts as a bridge between video playback and data generation. The system includes a video player, event detector, and data generator that work together to automatically create structured game event data from video content, eliminating the need for manual entry while maintaining accuracy.
2Quantity of substance
If multiple users simultaneously record and process game events, then data completeness is improved, but system complexity increases
Solution Approach 1:
The system divides the task of game event recording among multiple independent spectators, each using their own device to detect and report events. This distributes the data collection workload and enables parallel processing of multiple video streams and event datasets.
Solution Approach 2:
The system merges data from multiple independent spectators into a unified game event dataset. By combining observations from multiple users watching the same game, the system achieves comprehensive data coverage while maintaining individual system simplicity.
3Loss of information
If users need to view and analyze specific game events, then information retrieval quality is improved, but navigation time through full videos increases
Solution Approach 1:
Game events are pre-detected and timestamped during video playback, creating an indexed structure of important moments. This preliminary organization of data by event type and timestamp allows users to quickly navigate to specific events without manually searching through entire video files.
Solution Approach 2:
The system replaces manual video navigation with automated event-based navigation. Instead of scrubbing through video timelines, users can directly access specific game events through structured data indexes that link event types, timestamps, and video segments.
Data Source
AI summary
A mobile application is disclosed enabling a first sporting event spectator to efficiently record game actions and a second sporting event spectator to simultaneously record real-time video of the game actions. Using a mobile device having a touch screen, the first user can efficiently, and with limited user interaction, indicate fast paced game actions of players engaged in a sport. Using a separate mobile device, or a video system in communication with a network, the second user can record video of a presently occurring game in which the game actions occur. A system in communication with the first and second users' devices can receive indications of game actions, and receive video of the game, and associate each indicated game action with a portion of the video of the game action. The system may, for example, use these associations to generate an index that enables users to view descriptions of the game actions and jump to corresponding video clips.
