Media Service Device Assignment with Access Privilege Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media services face challenges in managing simultaneous access by multiple devices and users, as current solutions either allow unrestricted access leading to unauthorized use or restrict access to a single device at a time, which is not practical for family sharing or concurrent use across multiple devices.
Innovation Solution
A user interface and method for assigning devices to a media service based on access privilege information, allowing multiple devices of specific types to be assigned until a limit is reached, thereby controlling further assignments and ensuring authorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If unrestricted access is allowed to media service, then ease of operation is improved, but security and authorization control deteriorate
Solution Approach 1:
The system changes the parameter of device assignment from unrestricted to limited by implementing a device limit parameter. The media service provider server assigns a maximum number of devices that can access the media service, transforming the access model from open to controlled while maintaining ease of use through automated assignment processes.
2Reliability
If single device access is restricted per account, then security is improved, but adaptability and user experience deteriorate
Solution Approach 1:
The system implements dynamic device assignment where the number of accessible devices can be adjusted based on account type and service provider policies. Different account types (individual, family, business) have different device limits, allowing the system to adapt to various user needs while maintaining security through controlled access rather than rigid single-device restriction.
Solution Approach 2:
The system uses variable parameters for device limits based on account characteristics. Instead of a fixed single-device rule, the maximum number of devices becomes a configurable parameter that changes according to account type, enabling families to access media services on multiple devices simultaneously while maintaining authorization control.
3Adaptability or versatility
If multiple devices are assigned to media service, then adaptability is improved, but device complexity and management overhead increase
Solution Approach 1:
The system implements self-service device assignment where users can automatically register new devices without manual provisioning. When a new device connects to the media service, the server automatically checks the device limit parameter and assigns the device if capacity is available, eliminating complex manual management while enabling multiple device access.
Solution Approach 2:
The system provides feedback to users about device assignment status, informing them how many devices are currently assigned and whether additional devices can be added. This feedback mechanism simplifies management by giving users clear visibility into the system state without requiring complex monitoring or configuration.
Data Source
AI summary
A user interface is used to assign different devices and device types to media services where the number of different devices and device types that are capable of being assigned is determined by access privilege information corresponding to such media services. When a number of devices of a specific type are assigned where such a number exceeds a limit specified in the access privilege information, the assignment of additional devices of that specific type is halted.
