Content Management Device for Network Transfer Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital rights management systems fail to effectively manage content utilization during real-time distribution and transfer over networks, and they cannot adapt to various digital rights management rules, nor can they manage local and network-stored content using the same utilization system.
Innovation Solution
A content management system that assesses accessibility based on requesting device information and digital rights management, selects appropriate transfer methods (streaming or file transfer) for content files, and provides a unified interface for local and network-based content utilization, ensuring compliance with digital rights management rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital rights management is implemented to prevent unauthorized content utilization, then content security is improved, but content transfer and distribution capabilities are restricted
Solution Approach 1:
The patent implements dynamic utilization condition management where content accessibility is not fixed but determined in real-time based on requesting device information, digital rights management rules, and current utilization state. The system dynamically adjusts content transfer permissions by evaluating device authentication, content format compatibility, and transfer method appropriateness at the moment of each transfer request, allowing flexible security enforcement without restricting legitimate content distribution
Solution Approach 2:
The patent changes the parameters of content utilization by introducing multiple evaluation dimensions including device information parameters, content format parameters, and transfer method parameters. By evaluating these parameters collectively and selecting optimal transfer methods (streaming vs. file transfer) based on content format and utilization conditions, the system maintains security while adapting to various content distribution scenarios
2Device complexity
If a unified utilization system is implemented for both local and network-stored content, then system complexity is reduced, but management precision of different content sources is compromised
Solution Approach 1:
The patent implements a universal utilization management system that handles both local and network-stored content through the same interface and evaluation framework. The content management device provides unified content listing, authentication, and transfer functionality regardless of whether content is stored locally or on the network, allowing users to access content from either source without needing separate management systems
Solution Approach 2:
While maintaining a unified system interface, the patent applies location-specific evaluation criteria by considering the storage location (local or network) as a factor in determining utilization conditions and selecting appropriate transfer methods. The system evaluates device information and content attributes differently based on whether the content resides locally or on the network, ensuring precise management of each content source while presenting a unified interface
3Reliability
If content accessibility is determined at utilization time rather than distribution time, then digital rights management enforcement is improved, but real-time content distribution efficiency is reduced
Solution Approach 1:
The patent performs preliminary evaluation by pre-assessing device information, content format compatibility, and appropriate transfer methods before actual content transfer begins. The system evaluates utilization conditions and selects the optimal transfer method (streaming or file transfer) in advance, so that when content transfer is initiated, the path is already determined and execution can proceed efficiently without real-time decision delays
4Adaptability or versatility
If multiple transfer methods are supported for different content formats, then content transfer adaptability is improved, but system complexity increases
Solution Approach 1:
The patent manages transfer method complexity by evaluating content format as a key parameter and mapping it to appropriate transfer methods. The system considers content attributes (such as whether content is suitable for streaming or requires file transfer) and device capabilities, then selects the optimal transfer method based on these parameter evaluations. This parameter-based approach allows the system to support multiple transfer methods adaptively while maintaining manageable complexity through systematic evaluation criteria
Data Source
AI summary
A system estimates accessibility on the basis of information of a requesting device and digital rights management information of content when a utilization request of the content is raised through a network. In a device including a hard disk for storing a plurality of content files and having a networking function for transmitting the content file to other device, a utilization condition and a utilization state are so managed as to correspond to the content file and when a utilization request of a content file is made, utilizability of the content file is judged from a utilization object in the utilization request and from information of a transmitting device of the utilization request. When utilization is not judged as possible, a report is made to the transmitting device of the utilization request to the effect that the content file cannot be utilized.
