Universal Video Lookup System for Cross-Repository Metadata Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to seamlessly correlate and retrieve metadata associated with specific video content across different repositories, as identifiers are not interchangeable, leading to difficulties in accessing and synchronizing video content from various sources.
Innovation Solution
The implementation of a universal video lookup system that identifies and correlates multiple video content identifiers, aggregates metadata from various sources, and aligns subtitle information by translating identifiers and calculating spatial and temporal correspondence between video sequences, using a framework akin to 'video genomics' for spatio-temporal matching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different identifier systems are used for different video repositories and metadata sources, then each system can maintain its own unique identification method, but identifiers cannot be interchangeable across systems
Solution Approach 1:
The patent introduces a GUID translation service as an intermediary component that receives identifier queries from applications and automatically translates them between different identifier systems (DVDid, moviehash, URL, etc.). This mediator handles the complexity of multiple identifier systems internally while presenting a unified interface to users, thus improving identifier compatibility without requiring applications to directly manage system complexity.
Solution Approach 2:
The GUID translation service is designed with universal functionality to handle multiple types of identifiers (DVDid for DVDs, moviehash for BitTorrent, URLs for web content, etc.) through a single unified system. This multi-functional approach allows the same service to translate between any identifier types, improving adaptability across different video repositories and metadata sources without requiring separate translation mechanisms for each system.
2Loss of information
If multiple metadata repositories are accessed to aggregate video information, then comprehensive metadata can be retrieved, but retrieval time and system complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-establishing connections and translation mappings between multiple metadata repositories (Wikipedia, IMDB, OpenSubtitles, DVDXML) before actual metadata retrieval is needed. The GUID translation service pre-loads and caches identifier translation rules and repository access patterns, so that when comprehensive metadata is requested, the system can quickly aggregate information from multiple sources without experiencing the full overhead of establishing connections and understanding different repository structures from scratch.
3Adaptability or versatility
If video content is synchronized across different platforms with varying formats and advertisements, then content accessibility improves, but synchronization accuracy deteriorates
Solution Approach 1:
The system creates standardized copies of video content metadata and timing information that are platform-independent. By generating unified GUID-based representations of video content that replicate the essential temporal and spatial characteristics across different platforms, the system maintains synchronization accuracy while enabling broad accessibility. The GUID translation service creates these standardized copies by translating platform-specific identifiers into a universal format that preserves timing and formatting information.
Data Source
AI summary
A universal video-related lookup system and method receives a request for information associated with specific video content from a requesting device. The system and method identify a first video content identifier associated with the specific video content and retrieves first metadata associated with the specific video content based on the first video content identifier. Next, the system and method translate the first video content identifier into a second video content identifier associated with the specific video content and retrieves second metadata based on the second video content identifier. The first metadata and the second metadata are then provided to the requesting device.
