Playback Queue Media Replacement for Private Offline Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media playback systems lack the ability to selectively add media from a personal device to a media queue while preserving user privacy and maintaining access to equivalent media when the personal device is disconnected.
Innovation Solution
A system and method that allows users to selectively add a subset of media from a personal device to a media system queue, providing access to equivalent media even when the personal device is out of range, while ensuring privacy by controlling what content is shared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all media from a personal device is added to the media queue, then media availability is improved, but user privacy is compromised
Solution Approach 1:
The patent divides the media library into two distinct subsets: a first subset that is shared with the media system and a second subset that remains private. This segmentation allows users to selectively control which media files are made available, resolving the contradiction between media availability and privacy protection.
Solution Approach 2:
Different quality attributes are applied to different portions of the media library. The first subset of media is configured with shared accessibility attributes, while the second subset maintains private accessibility attributes. This local differentiation enables simultaneous achievement of media availability for shared content and privacy protection for private content.
2Loss of information
If media is selectively added from a personal device, then user privacy is preserved, but access to media may be lost when the device is disconnected
Solution Approach 1:
The system performs preliminary actions by creating equivalent media representations and storing them in the media library before the personal device is disconnected. This advance preparation ensures that media access continuity is maintained even when the personal device becomes unavailable, while still preserving user privacy through selective sharing.
Solution Approach 2:
The patent creates equivalent copies of media files from the first subset and stores them in the media library. These copies serve as backups that ensure reliable media access when the personal device is disconnected, while the original selective sharing mechanism continues to protect user privacy.
3Reliability
If equivalent media is pre-stored in the media library, then media access reliability is improved, but system resource usage increases
Solution Approach 1:
The system extracts only the necessary equivalent media files from the personal device and stores them in the media library, rather than duplicating the entire media library. This selective extraction reduces system resource usage while maintaining media access reliability for the shared subset of media.
Solution Approach 2:
The patent implements partial action by creating equivalent media representations only for the first subset of media that is designated for sharing, rather than for the entire media library. This partial approach maintains reliability for accessible media while minimizing unnecessary system resource consumption.
Data Source
AI summary
Embodiments are provided for replacing media items in a queue of a playback device. An example implementation involves receiving, at the playback device, first data indicating an addition of a first media item to a queue. The playback device determines that the first media item is no longer accessible to the playback device at a later second time. The playback device initiates a query for a media item similar to the first media item and receives second data indicating that a second media item has replaced the first media item in the queue, the second media item being similar to the first media item. In response, the playback device initiates playback of the second media item on the playback device.
