Video Navigation Metadata Analysis Reducing Hardware Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current TV sets face challenges in managing and executing video navigation functions due to the heavy load on hardware and software from the increasing amount of metadata required, leading to potential quality deterioration and increased development costs, with existing solutions not addressing the efficient management of metadata in diverse forms of video content.
Innovation Solution
A video content viewing apparatus that acquires and stores metadata from an external device, utilizing a metadata analysis unit to select and analyze video navigation functions, verify metadata completeness, and synthesize new metadata for specific themes, thereby reducing the load on the viewing apparatus's hardware and software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a huge amount of metadata is stored and processed on the viewing apparatus side, then video navigation functions can be executed, but the hardware configuration, memory capacity, and processing power requirements increase, leading to increased development costs
Solution Approach 1:
The patent extracts the metadata storage and management function from the viewing apparatus and relocates it to external servers. The viewing apparatus only retains lightweight metadata analysis and execution capabilities, while the bulk metadata storage and management is performed externally, thereby reducing hardware complexity while maintaining video navigation functionality
Solution Approach 2:
The patent introduces a metadata management server as an intermediary between the content delivery system and the viewing apparatus. This mediator handles the heavy lifting of metadata storage, verification, and synthesis, allowing the viewing apparatus to execute video navigation functions without bearing the full hardware burden
2Adaptability or versatility
If a huge amount of metadata is stored and processed on the viewing apparatus side, then video navigation functions can be executed, but processing power requirements increase, leading to increased development costs
Solution Approach 1:
The patent extracts the computationally intensive metadata processing tasks from the viewing apparatus and relocates them to external servers. Only lightweight analysis and execution remain on the client side, significantly reducing processing power requirements while preserving video navigation capabilities
Solution Approach 2:
A metadata management server acts as an intermediary that handles heavy computational tasks including metadata verification, completeness checking, and synthesis. This mediator absorbs the processing burden, allowing the viewing apparatus to execute navigation functions with minimal processing power
3Adaptability or versatility
If the amount of metadata is increased, then more video navigation functions can be supported, but the quality of video navigation execution may deteriorate due to incomplete or incorrect metadata
Solution Approach 1:
The patent implements a feedback mechanism where the viewing apparatus sends execution results and metadata quality information back to the metadata management server. The server uses this feedback to verify metadata completeness, detect errors, and perform corrections, thereby maintaining high reliability even as metadata volume increases
Solution Approach 2:
The patent performs preliminary verification and correction of metadata on the server side before it reaches the viewing apparatus. By pre-processing metadata to ensure completeness and accuracy, the system prevents execution failures and maintains reliable video navigation function performance
Data Source
AI summary
A multifunction video navigation display is achieved without adding an extra load onto hardware or software of a viewing apparatus. In such a video content viewing apparatus, a memory unit acquires video contents and metadata to execute video navigation functions from an external server and stores them, a metadata analysis unit verifies completeness of the acquired metadata and corrects/complements an incomplete portion of the metadata, and a navigation unit executes the selected video navigation function according to an analysis result provided from the metadata analysis unit.
