Timestamp Synchronization for Visual Media Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for managing visual media inaccurately determine media timelines due to inaccurate or incomplete timestamp information, which varies across capture devices, leading to incorrect organization and viewing of media files.
Innovation Solution
The system analyzes the accuracy and fidelity of timestamp information in metadata from various capture devices, generates and synchronizes high-fidelity capture timestamps across media files, and adapts to different metadata formats and content for improved media management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional systems rely on timestamp information from various capture devices to organize media files, then media files can be organized on a timeline, but the timestamp accuracy deteriorates due to variations across devices
Solution Approach 1:
The patent introduces a synchronization server as an intermediary that receives timestamps from multiple capture devices, processes them through synchronization algorithms, and distributes corrected timestamps back to the devices. This mediator resolves the timestamp accuracy problem by centralizing the synchronization function rather than relying on individual device timestamps.
Solution Approach 2:
The system changes the timestamp parameter by adjusting and synchronizing time values across different capture devices. The synchronization process modifies the original timestamps to ensure they are consistent and accurate across all devices, transforming unreliable device-specific timestamps into reliable synchronized timestamps.
2Adaptability or versatility
If the system processes metadata from multiple capture devices with different formats, then adaptability improves, but processing complexity increases
Solution Approach 1:
The patent implements a universal metadata processing framework that can handle multiple capture device formats through a single standardized interface. The system defines common metadata schemas that work across different device types, allowing one processing pipeline to serve multiple format requirements without requiring separate processing paths for each device.
3Productivity
If conventional systems use device-specific timestamp information, then processing simplicity is maintained, but timeline accuracy deteriorates
Solution Approach 1:
The system performs preliminary timestamp synchronization before media file processing and organization. By pre-synchronizing timestamps across all capture devices before the actual media processing begins, the system ensures accurate timelines without adding complexity to the subsequent processing steps. This preliminary action resolves the accuracy issue while maintaining processing efficiency.
Data Source
AI summary
The present disclosure relates to systems, non-transitory computer-readable media, and methods for synchronizing timestamps associated with media files across a variety of capture devices. For example, the disclosed systems receive a media file captured with a user device and determine, from metadata, initial timestamp information for the media file that includes inaccurate or incomplete time zone information. The disclosed systems determine a predicted time zone for the media file by extracting GPS information from the metadata associated with the media file or identifying a peer media file and utilizing a time zone or GPS information associated with the peer media file. The disclosed systems generate a synchronized timestamp for the media file with updated timestamp information based on the predicted time zone.
