Multi-User Content Queue for Unified Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Content output devices, such as smart speakers, typically restrict access to content libraries to a single user account, preventing multiple users in a household from adding content from their libraries to a shared playlist without cumbersome processes.
Innovation Solution
Implementing a multi-user content queue system that stores and manages content libraries and user account credentials for multiple users, allowing unified playback of content from various user accounts without requiring separate playlists or account changes, and enabling seamless transfer between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content output devices restrict access to content libraries to a single user account, then content security and authorization control are maintained, but multiple users cannot add content from their libraries to a shared playlist without cumbersome processes
Solution Approach 1:
The system segments content libraries by user accounts while maintaining a unified playback queue. Each user's content library remains separately authorized and secure, but the playback queue integrates content from multiple users seamlessly, allowing easy addition of content without requiring account switching or complex manual processes
Solution Approach 2:
The content output device acts as an intermediary that manages multiple user credentials and authorization tokens. It automatically handles the complexity of authenticating with different content libraries and retrieving authorized content, shielding users from the underlying complexity while enabling seamless multi-user content sharing
2Adaptability or versatility
If separate playlists are created for each user, then content authorization is maintained, but the process becomes cumbersome and loses the benefit of shared playback
Solution Approach 1:
The system merges multiple user-specific playlists into a single unified content queue for playback. While content is originally organized in separate user playlists to maintain authorization, the playback queue combines them into one seamless stream, allowing flexible content sharing from all users without requiring separate playlist management during playback
3Reliability
If account changes are required to access different user content, then content security is maintained, but playback continuity is disrupted
Solution Approach 1:
The system performs preliminary authentication by storing multiple user account credentials and authorization tokens in advance. When a user requests content from another user's library, the device already has the necessary credentials cached, allowing immediate playback without account switching or context loss, thus maintaining continuous playback while preserving content security
Data Source
AI summary
A device implementing a multi-user content queue may include a memory and at least one processor configured to receive, on the device, a content query and retrieve, from the memory, user account credentials corresponding to user accounts associated with the device. The at least one processor may be further configured to provide, to a server, the user account credentials and the content query. The at least one processor may be further configured to receive, from the server and based on the content query, a user account identifier of one of the user accounts and a content identifier corresponding to content in a content library of the one of the user accounts. The at least one processor may be further configured to utilize the user account identifier and the content identifier for output, by the device, of the content from the content library of the one of the user accounts.
