License Information Conversion Apparatus for Cross-System Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional content distribution systems face challenges in transferring and interpreting license information between different systems, preventing users from seamlessly utilizing their license information across various content distribution systems due to structural differences in license formats and compatibility issues between terminal apparatuses.
Innovation Solution
A conversion apparatus is developed to convert license information from one format to another, ensuring compatibility between different terminal apparatuses by processing and transforming the license information to match the specific requirements of the target system, allowing for secure and compatible usage across various content distribution systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If license information is transferred between different content distribution systems, then users can utilize their license information across various systems, but structural differences in license formats prevent compatibility between terminal apparatuses
Solution Approach 1:
The patent introduces a conversion apparatus that acts as an intermediary between different content distribution systems. This apparatus receives license information in a first format, converts it to a second format, and outputs it for use in different systems. The conversion apparatus mediates the incompatibility between different license formats, enabling seamless transfer and utilization of license information across systems without requiring changes to the terminal apparatuses themselves.
Solution Approach 2:
The patent applies parameter changes by transforming the structural parameters of license information from one format to another. The conversion apparatus modifies specific parameters such as data structure, encoding format, and organizational layout of license information to match the requirements of different content distribution systems, thereby achieving compatibility while preserving the essential licensing data.
2Reliability
If terminal apparatuses use different license information structures, then each system can maintain its own security and format requirements, but users cannot transfer license information between systems
Solution Approach 1:
The conversion apparatus serves as a intermediary that preserves the security and format integrity of each system while enabling transferability. It receives license information from one system, maintains the essential security parameters, transforms the format, and outputs it for the target system. This allows each content distribution system to maintain its own security requirements while users can transfer license information between systems.
3Adaptability or versatility
If license information conversion is performed, then compatibility between terminal apparatuses is achieved, but processing load increases
Solution Approach 1:
The conversion process is segmented into distinct functional modules within the conversion apparatus, including reception modules for receiving license information in the first format, conversion modules for transforming the format, and output modules for providing the converted license information. This segmentation allows for efficient processing and reduces the overall processing load by distributing the conversion tasks across specialized components.
Data Source
AI summary
Each of at least two terminal apparatuses uses content data in accordance with license information which is generated by a content distribution system to which it subscribes. A conversion apparatus includes a working area for storing license information which is compatible with one of the terminal apparatuses, and a central processing section for converting the license information stored in the working area into license information which is compatible with the other terminal apparatus. Thus, there is provided a conversion apparatus which can convert one's own license information so as to be passable to others.
