Media Metadata Processing via Flat Table Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media stream containers, such as MPEG 7, lack efficient mechanisms for transforming, embedding, extracting, and reasoning media metadata, particularly due to complex XML-based protocols that require cumbersome data manipulation and querying processes.
Innovation Solution
A system that parses metadata components from media data streams, marks them with computational closures, and uses serialized semantic data structures like RDF to facilitate efficient processing, embedding, and reasoning, enabling scalable and flexible media stream processing across heterogeneous environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If XML-based protocols are used for metadata processing, then media stream containers can store metadata, but the processing becomes complicated and time-consuming due to complex data manipulation and querying processes
Solution Approach 1:
The patent changes the data representation parameter from XML-based hierarchical structures to flat table structures with standardized columns (id, title, artist, album, year, genre). This parameter change transforms complex XML parsing and tree traversal operations into simple SQL queries, dramatically reducing processing time while maintaining comprehensive metadata processing capability
Solution Approach 2:
The patent replaces the mechanical XML parsing and tree manipulation system with a database-driven SQL query system. Instead of manually navigating complex XML structures through programming layers, the system uses standardized database tables and SQL queries to retrieve and process metadata, simplifying the processing mechanism and reducing computational complexity
2Quantity of substance
If XML-based protocols are used for metadata processing, then media stream containers can store metadata, but the query expressions become complicated due to multiple ways to map XML to logical trees
Solution Approach 1:
The patent changes the data structure parameter from hierarchical XML trees to flat relational tables with explicit column definitions. This eliminates the ambiguity of XML mapping by providing a single, unambiguous table schema that directly represents the logical structure, making query expressions simple and deterministic without requiring complex mapping logic
Solution Approach 2:
The patent segments the metadata into separate, well-defined table columns (id, title, artist, album, year, genre) rather than nesting everything in XML attributes and elements. This segmentation makes the data structure explicit and simple, allowing straightforward SQL queries without needing to navigate complex hierarchical relationships or deal with multiple valid XML mappings
3Adaptability or versatility
If existing media stream containers like MPEG 7 are used, then audio, video and metadata processing mechanisms are built-in, but transformation, embedding, extracting, and reasoning capabilities are limited
Solution Approach 1:
The patent creates a universal database layer that handles multiple metadata processing functions (transformation, embedding, extraction, reasoning) through a single standardized interface. The flat table structure with standardized columns serves as a universal data model that can support various processing operations without requiring separate specialized mechanisms for each function, making the system both versatile and simple
Data Source
AI summary
An approach is provided for processing metadata in one or more media streams. A media metadata processing platform determines to parse from a media data stream for metadata components. The media metadata processing platform also causes, at least in part, a storing of the parsed metadata components. The media metadata processing platform further determines to mark the media data stream with one or more hooks for embedding the parsed metadata components, one or more computational closures, or a combination thereof, the one or more computational closures being serialized.
