Real-Time Video Highlight Tagging via Time Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for tagging video files during live events are cumbersome, as they require physical copies or online access to the entire event video, making it difficult to identify and share specific moments, and existing solutions are limited to synchronized networks and devices.
Innovation Solution
A method allowing real-time remote tagging of video files using a mobile device, where users can generate and synchronize highlight-markers with a server system, enabling selection of specific video sections without direct connection to the recording device, using time references and event identifiers for accurate tagging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users want to access and tag specific portions of recorded events, then they need to view and navigate the entire event video, but this requires physical copies or online access to the complete video which is cumbersome and time-consuming
Solution Approach 1:
The patent segments the event video into multiple sections, each associated with specific time references and event identifiers. This allows users to directly access and tag specific portions without viewing the entire video, dividing the large video file into manageable, identifiable segments for efficient navigation and tagging.
Solution Approach 2:
The system performs preliminary actions by pre-processing the video file to extract time references and event identifiers before the user needs to tag anything. This preparation work is done in advance, so when users want to tag specific portions, the video is already segmented and indexed, eliminating the need for manual scanning and identification.
2Measurement precision
If the system requires direct connection to the recording camera for tagging, then time synchronization can be achieved, but this limits accessibility and requires all devices to be registered and synchronized with the network
Solution Approach 1:
The patent introduces time references and event identifiers as intermediary elements that bridge the recording camera and the mobile device. Instead of requiring direct connection between the camera and tagging device, the system uses these intermediaries to convey timing information, allowing any device to tag video portions without direct camera connection while maintaining synchronization accuracy.
Solution Approach 2:
The system creates copies of time reference information from the camera's time reference system and stores them in the video file metadata. This copying allows the time synchronization data to be transferred and used by any mobile device without requiring the original camera connection, enabling versatile access while preserving timing precision.
3Loss of information
If the entire event video is stored and accessed, then complete event coverage is available, but this increases storage requirements and makes sharing specific moments inefficient
Solution Approach 1:
The patent extracts specific time references and event identifiers from the complete event video and stores them as metadata in the video file. This extraction allows the system to preserve all event moments in the full video while enabling efficient access to specific portions through the extracted time markers, reducing the need to store and transmit entire video files for sharing specific moments.

AI summary
The invention relates to a method for remote and real-time selecting a section in a video file with a mobile device, wherein a spectator attending an event selects a section of a video file by sending a highlight-marker from his mobile device to a server system, wherein the selection can be performed without the user having access to the camera recording the event. Highlight-marker and video file are systematically time synchronized. Furthermore, the invention relates to a method for generating a highlight-video from a plurality of highlight sections.
