Playlist Positioning With Rights Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media group systems fail to effectively manage user requests to add media items to playlists, particularly in ensuring that only authorized users can add items at desired positions, and do not account for user preferences and rights when determining playlist positions.
Innovation Solution
The system allows users to request media items for specific playlist positions, determining if they have rights to the item by comparing metadata, and if authorized, adds the item at the requested position while providing different versions to users based on their access rights, and uses preference indicators to optimize playlist placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system allows any user to add media items to the playlist at any position, then the ease of operation is improved, but the reliability of rights management deteriorates
Solution Approach 1:
The system introduces an intermediary rights verification mechanism that mediates between user requests and playlist modification. When a user requests to add a media item, the system checks rights metadata associated with the user and the media item before allowing the addition. This intermediary verification process maintains ease of operation for authorized users while ensuring reliability of rights management by blocking unauthorized modifications.
2Reliability
If the system checks user rights for each media item request, then the reliability of rights management is improved, but the productivity of playlist management deteriorates
Solution Approach 1:
The system performs preliminary rights verification by checking rights metadata in advance before processing media item addition requests. The rights information is pre-associated with user profiles and media item identifiers, allowing the system to quickly verify authorization without complex real-time checks. This preliminary preparation maintains high reliability of rights management while improving productivity by reducing the computational overhead during actual playlist operations.
3Adaptability or versatility
If the system provides different versions of media items to different users, then the adaptability of the system is improved, but the device complexity deteriorates
Solution Approach 1:
The system applies local quality by providing different versions of media items tailored to specific user rights and preferences. Instead of managing completely separate versioning systems, the system maintains a core media item structure with user-specific attributes or metadata that indicate the appropriate version. This approach enables adaptability in media delivery while reducing device complexity by avoiding the need for complex version control mechanisms, as each user receives a customized version based on their local rights context.
Data Source
AI summary
Systems, device and techniques are disclosed for receiving a request from a user to add a media item to a playlist at a certain playlist position where the media items in the playlist are provided to other users in a media group. Based on a determination that the requesting user has rights to the requested media item, the requested media item may be added to the playlist at the position. When the playlist reaches the position, the user that added the media item to the playlist may be provided with a first version of the media item and the other users in the group may be provided with a second version of the media item. If the user that requested the item to be added to the playlist is determined not to have rights to the media item, the item is added to a position different than the requested position.
