Playback Queue Access Levels for Shared Media Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media playback systems lack the ability to provide private playback queues, allowing users to control access to their media playlists, leading to potential unauthorized access and privacy issues.
Innovation Solution
Implementing private playback queues in media playback systems, where users can add songs or playlists to a queue that remain private unless authorized, with access control based on user credentials and system settings, ensuring only authorized users can view or modify the queue contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If playback queues are made accessible to all users in a shared media system, then ease of operation and collaborative playback are improved, but privacy and unauthorized access control deteriorate
Solution Approach 1:
The patent segments the playback queue into public and private portions, allowing different access levels for different users. The queue is divided such that certain media items are accessible to all users while other items remain restricted to specific authorized users only, resolving the contradiction between collaborative access and privacy protection.
Solution Approach 2:
The patent implements local quality by applying different access permissions to different portions of the same playback queue. Each media item or playlist within the queue can have its own access control settings, allowing specific users to access certain items while restricting access to other items, thus enabling both collaboration and privacy simultaneously.
2Object-affected harmful factors
If private playback queues are implemented with access control, then privacy and security are improved, but device complexity and ease of operation worsen
Solution Approach 1:
The patent implements self-service by allowing users to automatically set and manage their own access permissions for private playlists. The system provides automated access control mechanisms where users can define which users should have access to their private content without requiring manual intervention from the system administrator or complex configuration procedures, thus reducing perceived complexity while maintaining privacy.
3Object-affected harmful factors
If private playlists are added to the playback queue, then privacy control is improved, but loss of information about the complete queue contents worsens
Solution Approach 1:
The patent resolves this contradiction by adding a new dimension of information visibility - the system maintains metadata information about private playlists (such as existence, number of items, or generic descriptions) that is visible to all users, while the actual private content remains inaccessible. This allows the system to preserve privacy control while preventing complete information loss about queue contents.

AI summary
Based on a credential, an access level of a playback queue for a first control interface and a first subset and second subset of media items in the playback queue may be determined. Media items in the playback queue that were added via a second control interface may be included in the first subset. Media items that were added via a control interface different from the second control interface may be included in a second subset. Information may be provided which identifies the first subset of the media items in the playback queue and the second subset of the media items in the playback queue.
