Mobile Device Content Management with DRM License Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in managing digital contents on mobile devices, particularly in distinguishing between DRM and non-DRM contents, as well as license-expired and usable DRM contents, leading to inconvenience in content management and repurchasing processes.
Innovation Solution
A method and apparatus for intuitively managing contents on mobile devices, which includes classifying contents into DRM and non-DRM types, separating and searching for license-expired DRM contents, and providing a user interface for easy identification and removal or transfer of expired contents, allowing for simpler content management and repurchasing of licenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DRM technology is applied to protect digital contents, then copyright protection is improved, but user convenience in managing contents deteriorates
Solution Approach 1:
The patent segments contents into distinct categories (DRM contents and non-DRM contents) and further segments DRM contents into usable and license-expired groups. This segmentation is achieved through separate storage folders and visual classification in the content list, allowing users to easily identify and manage different types of contents without being confused by their mixed presence, thus resolving the contradiction between maintaining DRM protection and improving user convenience.
2Quantity of substance
If all contents are mixed in a single content list, then storage efficiency is improved, but ease of identifying content status deteriorates
Solution Approach 1:
The patent divides the content list into visually distinct groups: DRM contents and non-DRM contents are separated through different icons and visual indicators. Within DRM contents, further segmentation occurs between usable contents (with valid licenses) and license-expired contents through distinct visual markings. This allows users to quickly identify content status without manual checking, while all contents remain accessible in a unified interface.
Solution Approach 2:
The patent employs visual indicators including color changes, icon variations, and graphical markers to differentiate between DRM and non-DRM contents, as well as between usable and license-expired DRM contents. These visual cues enable users to instantly recognize content status and make informed decisions about content management without complex interactions.
3Device complexity
If users manually track license status, then system complexity is reduced, but time consumption increases
Solution Approach 1:
The patent implements an automated system where the mobile device itself tracks and monitors license status for DRM contents. The system automatically identifies which DRM contents have expired licenses and visually distinguishes them in the content list, eliminating the need for users to manually track license status. This self-service approach reduces user time investment while maintaining manageable system complexity through automated background processes.

AI summary
A method and an apparatus which permits intuitive management of a variety of digital contents stored in a mobile device. In a method for managing the contents, the mobile device determines a type of the content when a play of the content is ended. If the content is digital rights management (DRM) content, the mobile device checks a license count for authorized access to the DRM content and then determines whether or the license has expired or will expire shortly. If the license has expired, the mobile device removes the license-expired DRM content, or alternatively transfers the license-expired DRM content to a specified folder.
