Zone Scene Control for Dynamic Multi-Zone Audio Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional multi-zone audio systems are inflexible in managing dynamic groupings of audio players and adjusting volume settings, requiring manual adjustment of each player and being unsuitable for ad-hoc changes in audio preferences.
Innovation Solution
A mechanism allowing users to create and manage groups of multimedia players by themes or scenes, enabling synchronized playback and volume control across zones, with a controller facilitating the formation, management, and activation of these groups, including parameters like audio sources and volume settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional multi-zone audio systems use pre-programmed controller configurations, then audio sources can be distributed to specific zones, but the system becomes inflexible and cannot accommodate dynamic changes in audio preferences or ad-hoc grouping requirements
Solution Approach 1:
The system transitions from static pre-programmed configurations to dynamic groupings where zones can be flexibly assigned to audio sources in real-time. Users can create, modify, and delete groups on-the-fly, allowing the system to adapt to changing audio preferences without requiring reconfiguration of the entire system architecture.
Solution Approach 2:
The audio system is divided into independent zones that can be individually assigned to different audio sources or grouped together. Each zone operates as an independent unit that can be dynamically included or excluded from groups, enabling flexible segmentation and reconfiguration of the multi-zone system.
2Productivity
If audio players are controlled individually in traditional systems, then each zone can play different audio sources, but volume adjustment and grouping management become complex and time-consuming
Solution Approach 1:
Multiple zones are merged into logical groups that can be controlled as a single entity. When zones are grouped together, they share common audio sources and can be adjusted collectively, reducing the complexity of managing individual zone configurations while maintaining the ability to play different audio sources in different zones.
Solution Approach 2:
The system introduces an intermediary grouping layer between individual zones and audio sources. This grouping mechanism acts as a mediator that simplifies control by allowing users to manage multiple zones through a single group configuration, reducing the number of individual adjustments required.
3Adaptability or versatility
If a centralized location provides audio sources to multiple zones, then source sharing is enabled, but the system requires cross-bar devices and complex routing to prevent audio sources from going to unintended players
Solution Approach 1:
The audio routing system transitions from static cross-bar switching to dynamic group-based routing. Audio sources can be dynamically assigned to groups of zones, and the routing automatically adapts when zones are added to or removed from groups, eliminating the need for complex cross-bar devices and manual routing configuration.
Data Source
AI summary
A computing device capable of controlling a networked media playback system receives data identifying a first zone player, a second zone player, and a zone scene including a predefined grouping of zone players including at least the first zone player and the second zone player. The computing device displays a representation of available zone players in the networked media playback system including a first selectable indication of the first zone player, a second selectable indication of the second zone player, and a third selectable indication of the zone scene that, when selected, causes the zone scene to be invoked such that the predefined grouping of zone players becomes configured for synchronous playback of media. While displaying the representation, the computing device receives a user input indicating that the zone scene has been selected to be invoked. Based on the user input, the computing device causes the zone scene to be invoked.
