Vehicle Movement Object Labeling Through Segmented Video Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia annotation and retrieval systems lack personalization, context, and flexibility, often requiring users to navigate through entire files to find specific segments, and struggle with ambiguous metadata and rigid user access controls, while failing to treat segments as independent database entries, leading to copyright issues and inefficient targeting.
Innovation Solution
A system for segmenting, annotating, and retrieving multimedia files using a database of metadata that allows deep linking, hierarchical classification, and user-specific access, enabling users to navigate directly to specific segments and associate metadata with logically segmented files, while supporting multiple user types and facilitating targeted advertising.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users navigate through entire multimedia files to find specific segments, then they can access the content, but the time required to locate specific segments increases significantly
Solution Approach 1:
The patent segments multimedia files into smaller logical units (scenes, shots, clips) and creates independent database entries for each segment with its own metadata. This allows users to navigate directly to specific segments through the database without playing through the entire file, dramatically reducing the time to locate desired content.
Solution Approach 2:
The patent introduces a metadata database as an intermediary between the user and the multimedia file. The database stores segmented information and metadata, serving as a navigation index that enables direct access to specific segments without requiring users to manually search through the entire multimedia file.
2Productivity
If systems treat segments as independent database entries, then retrieval efficiency improves, but copyright compliance becomes more complex
Solution Approach 1:
The patent creates virtual copies of segment metadata in the database without physically copying the actual multimedia content. Each database entry contains metadata describing a segment (timing information, description, classification) that references the original file, enabling efficient retrieval while maintaining a single source of truth for copyright management.
Solution Approach 2:
The patent adds a metadata dimension to the multimedia file structure. Instead of only dealing with the physical file, the system creates a parallel metadata layer that organizes segments logically, enabling efficient retrieval through multiple classification dimensions (subject matter, time, location, etc.) without complicating the actual file structure or copyright status.
3Measurement precision
If metadata is used to describe multimedia files, then retrieval accuracy improves, but metadata ambiguity reduces effectiveness
Solution Approach 1:
The patent segments metadata into hierarchical levels (file-level metadata, segment-level metadata, scene-level metadata) with specific classification schemes at each level. This structured segmentation reduces ambiguity by providing clear, standardized metadata fields that precisely describe specific aspects of the multimedia content.
Solution Approach 2:
The patent transforms ambiguous free-text metadata into structured, standardized metadata with defined parameters and classification categories. By changing the format and organization of metadata from unstructured text to structured fields with controlled vocabularies, the system improves both retrieval accuracy and metadata clarity.
4Adaptability or versatility
If systems provide single-user access controls, then security is simplified, but flexibility for different user types decreases
Solution Approach 1:
The patent implements a universal access control framework that handles multiple user types (public, registered users, administrators) through a single standardized interface. The system uses user profiles and permission levels to provide different access rights while maintaining a unified database structure and metadata schema, enabling flexibility without proportionally increasing complexity.
Solution Approach 2:
The patent creates dynamic access controls where user permissions and visibility of metadata fields can change based on user type, registration status, and content sensitivity. The system adapts the level of access and metadata detail presented to each user dynamically, providing simplified views for casual users and comprehensive access for authorized users without requiring separate systems for each user type.
