Geolocation File Generation for Location-Based Video Content Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video platforms lack the ability to display personal multimedia content related to specific locations within a video being played, as geographic location information for individual frames is not typically stored or easily accessible.
Innovation Solution
An electronic system generates a geolocation file recording timestamps and locations from the video, scans multimedia files for matching metadata, and creates an association file to link relevant multimedia files with the video, allowing for the display of thumbnails and playback of matched files during video playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If geographic location information is stored in video files, then location-related multimedia content can be displayed during video playback, but video file complexity and storage requirements increase
Solution Approach 1:
The patent divides the location information storage into separate components: a geolocation file containing location data and timestamps, and an association file linking locations to multimedia content. This segmentation allows the main video file to remain simple while adding location functionality through separate, manageable files.
Solution Approach 2:
The patent introduces intermediary files (geolocation file and association file) that mediate between the video file and location-related multimedia content. These intermediaries contain the location metadata and linking information, allowing the video itself to remain simple while enabling location-based content display through the intermediary data structures.
2Adaptability or versatility
If location metadata is added to video files, then personal images and videos related to landmarks can be displayed, but processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary actions by pre-processing the video to extract keyframes and pre-generating the geolocation file with location data and timestamps before the actual playback. The association file is also pre-generated to link locations with multimedia content. This preliminary preparation eliminates the need for real-time processing during playback, significantly reducing computational resources and time during video viewing.
3Measurement precision
If geolocation data is stored for each frame, then accurate location matching is achieved, but storage space and data management complexity increase
Solution Approach 1:
The patent segments location data into discrete entries in the geolocation file, associating locations with specific timestamps rather than storing data for every individual frame. This segmentation maintains location matching accuracy by recording precise location information at key moments while significantly reducing the overall data volume and management complexity.

AI summary
A method of displaying multimedia content related to a location appearing in a video includes generating, based on the main video, a geolocation file that records timestamps and corresponding locations related to the main video, scanning through multimedia files to find one file from among the multimedia files that has metadata corresponding to the geolocation file and making the file serve as a matched file, associating the matched file with the main video by generating an association file for the main video, playing the main video, displaying a thumbnail of the matched file, and displaying the matched file when the thumbnail is selected.
