Terminal Content ID Generation for Network Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current content identification systems, such as those using Content Identity Managers (CIMs), face challenges in efficiently calculating and managing content IDs, leading to increased network load and difficulty in associating correct IDs with contents, especially when dealing with similar or identical contents in different formats.
Innovation Solution
A terminal and method that assist CIMs in calculating optimal content IDs by receiving content-related information, generating function information, and comparing generated IDs with stored IDs, allowing for refined content identification and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the CIM alone generates content IDs for all contents, then content identification is centralized, but the network load increases and the CIM becomes overloaded
Solution Approach 1:
The patent divides the content ID generation task between the terminal and the CIM. The terminal performs local content ID calculation for contents it generates or receives, while the CIM maintains centralized management for content ID assignment and conflict resolution. This segmentation reduces the CIM's processing load while maintaining centralized control benefits.
2Measurement precision
If the CIM calculates content IDs for similar contents in different formats, then content identification is comprehensive, but the network load increases
Solution Approach 1:
The terminal performs preliminary content ID calculation locally before transmitting content to the network. By pre-calculating content IDs at the terminal, the system avoids repeated network transmissions of content data for ID generation, reducing network load while maintaining identification accuracy.
3Adaptability or versatility
If different content IDs are assigned to the same content in different formats, then format variations are captured, but content association becomes difficult
Solution Approach 1:
The system implements feedback mechanisms where the terminal sends content ID information to the CIM, and the CIM provides feedback on content ID conflicts or associations. This feedback loop enables the system to recognize when different content IDs refer to the same content and establish proper associations, reducing management complexity.
