Zone Controller Hierarchical Media Device Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing networked media systems lack flexible control mechanisms that allow for dynamic grouping and reconfiguration of wireless speakers, limiting their use in varying scenarios beyond traditional surround sound setups.
Innovation Solution
The implementation of a zone functionality system that enables hierarchical control of networked media systems through the discovery, selection, and management of virtual media systems, using a zone controller to collectively manage and synchronize media sub-devices across a common data network, allowing for flexible grouping and reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless speakers are arranged into fixed sets for specific purposes (e.g., surround sound), then the system provides stable and reliable audio playback, but the system lacks flexibility to adapt to varying usage scenarios
Solution Approach 1:
The system segments the speaker system into independent controllable units (zones) that can be individually configured and combined. Each speaker or speaker group becomes a separate zone that can be dynamically added, removed, or reconfigured without affecting the entire system, enabling flexible adaptation to different usage scenarios while maintaining manageable complexity through modular organization
Solution Approach 2:
The system implements dynamic zone configuration where zones can be created, modified, and dissolved on-demand based on usage requirements. The zone structure allows speakers to transition between different groupings and purposes dynamically, moving from fixed pre-configured sets to flexible runtime reconfiguration, thereby achieving adaptability without permanent structural changes
2Ease of operation
If multiple virtual media systems are grouped into a zone for collective control, then the system achieves synchronized media playback across devices, but the control mechanism becomes more complex
Solution Approach 1:
The system merges multiple virtual media systems into a unified zone with a single control interface. By combining the control functions of individual speakers into a collective zone controller, the system enables synchronized media playback across all zone members through one interface, simplifying operation despite the underlying hierarchical complexity of managing multiple devices
Solution Approach 2:
The zone controller acts as an intermediary between the user and multiple media sub-devices. This intermediary layer abstracts the complexity of individual device control, providing a simplified interface that manages synchronization and coordination across all zone members while handling the hierarchical control structure internally, thereby improving ease of operation
Data Source
AI summary
A Zone Control service is disclosed which provides for hierarchically managing a plurality of networked media subsystems. This can provide a layer of abstraction for the collection in the form of a single Renderer zone interface represented by a delegated zone controller. This hierarchy establishes a virtual super-system. Although a Zone Control services can be advertised on all networked media devices, the services will typically be unavailable while a device is subservient to, or equivalently under the control of, a zone controller. A single instance of the Zone Control service can reside in a Services Device, co-existing with a Group Control service.
