Video Entity Linking for Flexible Metadata Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video systems connected to database systems are not flexible in handling user selections of visual entities, often failing to display metadata associated with selected entities when users choose semantic meanings over specific visual entities, such as selecting a player's score instead of the player themselves.
Innovation Solution
A transmission method in a video apparatus connected to a database system that allows users to select and link visual entities, with the system checking for the presence of selected entities and adding them to the database if not already present, using graphical features like color histograms for recognition and linking entities, enabling the association and display of metadata for both the selected and linked entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system stores metadata only for specific visual entities selected by users, then the system maintains data precision and avoids storing irrelevant information, but the system loses flexibility when users select semantic meanings (e.g., score) instead of the actual visual entities (e.g., player)
Solution Approach 1:
The patent introduces visual entity links as an intermediary mechanism between user selections and metadata retrieval. When a user selects a visual entity, the system uses the link to identify the actual visual entity of interest, even if the selection doesn't directly match. This mediator layer preserves metadata association accuracy while enabling flexible user interactions with semantic meanings rather than strict visual entity matching.
2Ease of operation
If the system requires exact matching between user selections and stored visual entities, then the system maintains measurement precision in entity identification, but the system reduces ease of operation when users want to select entities based on semantic meaning
Solution Approach 1:
Visual entity links serve as a mediator that bridges user selections based on semantic meaning with the actual visual entities stored in the system. The link structure allows the system to interpret user intent accurately without requiring exact visual entity matching, thus improving ease of operation while maintaining entity identification precision through the link relationship.
Solution Approach 2:
The system performs preliminary action by pre-establishing visual entity links between related entities (e.g., player and score) before user interaction. This allows the system to quickly resolve user selections to the correct visual entities and metadata without requiring complex real-time analysis, thereby improving both ease of operation and identification accuracy.
3Adaptability or versatility
If the system displays metadata only for the exactly selected visual entity, then the system maintains manufacturing precision in information delivery, but the system reduces adaptability when users select related entities instead of the target entity
Solution Approach 1:
The visual entity link acts as an intermediary that enables the system to deliver the correct metadata even when the user selects a related entity rather than the exact target. The link relationship preserves metadata delivery accuracy by mapping the selection to the intended visual entity, while simultaneously enabling flexible adaptability in how users can access information.
Data Source
AI summary
A transmission method in a video apparatus connected to a database system of visual entities is disclosed. The method comprises: - selecting (12, 32) a first visual entity in the video content; - selecting (14, 35) a second visual entity in the video content; - transmitting (16, 38) to the database system at least one information relative to an association of the first visual entity with the second visual entity. A receiving method in a database system of visual entities associated with metadata, the database system being connected to a video apparatus, is also disclosed.
