Media Asset Management Duplicate Detection

The patent segments media assets into standardized clips with unique identifiers and organizes them in a hierarchical structure. Each media asset is divided into discrete, identifiable segments (clips) that can be independently tracked across repositories. This segmentation enables efficient duplicate detection by comparing standardized clip identifiers rather than analyzing entire media files, thus resolving the contradiction between managing large quantities of assets and efficiently identifying duplicates.

The patent introduces a media asset management system as an intermediary layer between disparate repositories. This intermediary maintains a centralized index or catalog that maps clip identifiers to their locations across multiple repositories, enabling efficient duplicate identification without direct comparison of all media assets. The intermediary harmonizes metadata and provides unified access, resolving the difficulty of detecting duplicates across distributed storage systems.

The patent implements a nested hierarchical structure where media assets contain clips, clips contain segments, and derived assets reference parent assets through nested relationships. Each level maintains references to the levels below, creating a nested doll-like structure. This nesting enables automatic tracking of relationships between original and derived assets, as each nested level carries inheritance information, thus resolving the contradiction between high productivity and relationship tracking complexity.

The patent implements feedback mechanisms where the media asset management system automatically updates relationship metadata when new assets are created from existing clips. The system provides feedback about source asset relationships, usage statistics, and derivative chains back to developers and the central catalog. This automated feedback reduces the manual complexity of tracking relationships while maintaining high productivity in media development workflows.

The patent applies preliminary action by pre-computing and storing signatures (such as hash values or feature vectors) for media clips when they are first ingested into the system. These pre-computed signatures are stored in the centralized index, eliminating the need to re-process entire media files during duplicate detection. This preliminary action maintains high precision in duplicate detection while significantly reducing processing time during query operations.

The patent substitutes mechanical comparison of entire media files with computational signature matching. Instead of comparing audio-visual content directly (mechanical processing), the system uses cryptographic hashes or extracted feature signatures (computational substitution). This substitution maintains precise duplicate detection by comparing immutable signature values while dramatically reducing processing time and computational resources required.
