Playback Queue Control Transition for Media Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital audio systems lack seamless integration and control for accessing and playing digital media across multiple zones in a home environment, limiting the user's ability to effortlessly transition media playback between devices and zones.
Innovation Solution
A network media system that allows a mobile device to establish a connected state with a zone, enabling actions on a playlist to be synchronized with a playback queue, and automatically re-establishing or transferring control of the playback queue across zones, ensuring seamless media playback and control even when the device is out of range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile device establishes a connected state with a zone to enable synchronized playback control, then media playback control is improved, but the system becomes vulnerable to communication loss when the device moves out of range
Solution Approach 1:
The system proactively detects communication quality degradation and initiates control transition before complete disconnection occurs. The mobile device monitors communication status with the zone player and automatically transfers playback control to another device in the zone when communication deterioration is detected, ensuring uninterrupted service.
Solution Approach 2:
The system introduces a control transition mechanism that acts as an intermediary between the mobile device and zone player. When communication loss is detected, the control rights are transferred to another device within the zone, which then serves as the new intermediary for maintaining playback control, thus eliminating the harmful effect of communication breakdown.
2Reliability
If playback control is automatically transferred when communication is lost, then service continuity is improved, but the complexity of control management increases
Solution Approach 1:
The mobile device automatically monitors its own communication status with the zone player and autonomously initiates control transition when communication deterioration is detected. This self-service mechanism eliminates the need for manual intervention or complex centralized control logic, as each device independently manages its own connectivity and control rights.
Solution Approach 2:
The system implements a feedback mechanism where the mobile device continuously monitors communication quality with the zone player. When communication deterioration is detected through this feedback loop, the system automatically triggers control transition to another device in the zone, ensuring service continuity without requiring complex external management.
3Adaptability or versatility
If multiple devices can control playback in a zone, then adaptability is improved, but determining which device should control becomes more difficult
Solution Approach 1:
The system implements dynamic control authority assignment where the ability to control playback is not fixed but changes based on real-time communication conditions. When a mobile device's communication with the zone player deteriorates, control authority dynamically transfers to another device in the zone, allowing the system to adapt to changing network conditions while maintaining clear control attribution at any given moment.

AI summary
Embodiments provided herein involve connected states between a mobile device and one or more zones in a network media system and different interactions between the mobile device and the network media system involving the connected states. The connected states may be established between the mobile device and the one or more zones such that further actions taken on media items identified in the playlist on the mobile device may also be taken on corresponding media items in a playback queue associated with the one or more zones. The interface on the mobile device may display various graphical representations to indicate the different interactions involving the connected states, including when a connected state is established, when a connected state is lost, and when a reconnected state is reestablished. The interface may further provide selectable icons to allow a user to navigate among the different media playback options involving the connected states.
