Media Stream Metadata Tracks for Real-Time Search and Targeted Advertising
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mechanisms for searching media content are limited in efficiency and relevance, as they primarily rely on title or summary information, lacking the ability to utilize real-time metadata for targeted advertising and search refinement.
Innovation Solution
The integration of real-time metadata tracks into media streams allows for enhanced search and advertising capabilities by using metadata such as captions, subtitles, and device state information to drive queries and insert targeted content during media playback, enabling more contextual and frequent advertising opportunities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional search mechanisms using title or summary information are used, then the system is simple to operate, but the search relevance and advertising targeting capability deteriorates
Solution Approach 1:
The system performs preliminary extraction of metadata tracks (captions, subtitles, tags) from media content during indexing, preparing structured data in advance. This allows real-time searches to query pre-processed metadata rather than analyzing raw media content, improving search relevance while maintaining system efficiency
Solution Approach 2:
The patent introduces metadata tracks as an intermediary layer between the media content and the search system. These metadata tracks (containing captions, subtitles, tags, and other descriptive information) serve as a bridge that enables efficient querying without requiring direct analysis of the actual media content, thus improving search capability without proportionally increasing complexity
2Adaptability or versatility
If real-time metadata tracks are integrated into media streams, then the advertising targeting capability improves, but the data processing complexity increases
Solution Approach 1:
The system segments media content processing into distinct components: metadata extraction, metadata indexing, and metadata-based advertising selection. Each component handles specific tasks independently, allowing the system to leverage real-time metadata for targeted advertising while managing processing complexity through modular architecture
Solution Approach 2:
Metadata tracks are extracted and indexed in advance during media content processing, preparing structured data for later advertising decisions. This preliminary processing allows real-time advertising insertion to query pre-organized metadata without performing complex analysis during playback, thus improving targeting capability while controlling processing complexity
3Productivity
If frequent real-time advertising insertion is implemented, then the advertising revenue potential improves, but the system processing load increases
Solution Approach 1:
The system pre-processes and indexes metadata tracks during media content ingestion, organizing data by time stamps, topics, and keywords. This preliminary indexing enables frequent advertising queries to retrieve relevant ads quickly without performing complex real-time analysis, thus supporting high advertising insertion frequency while managing processing load
Solution Approach 2:
The metadata tracks contain self-descriptive information (captions, subtitles, tags) that automatically characterize the media content without requiring external analysis. This self-service capability allows the system to quickly match ads to content based on pre-existing metadata, enabling frequent advertising insertions with minimal additional processing
Data Source
AI summary
Real-time metadata tracks recorded to media streams allow search and analysis operations in a variety of contexts. Search queries can be performed using information in real-time metadata tracks such as closed captioning, sub-title, statistical tracks, miscellaneous data tracks. Media streams can also be augmented with additional tracks. The metadata tracks not only allow efficient searching and indexing, but also allow insertion of content specific advertising during appropriate portions of a media stream based on the content of the metadata tracks.
