Dynamic Zone Grouping for Multi-Zone Audio Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-zone audio systems struggle with dynamically managing ad hoc groups of audio players and controlling audio characteristics such as volume and playback operations across multiple zones, leading to an inconvenient and non-homogeneous audio environment.
Innovation Solution
A system that allows users to remotely control audio characteristics of multiple multimedia players through a controller, enabling synchronous playback and volume adjustment across groups or individual players, with a configurable module providing an interactive graphic user interface for grouping, de-grouping, and volume control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional multi-zone audio system uses pre-configured and pre-programmed controllers to manage different groups of audio players, then the system can satisfy specific audio playback requirements for different time periods, but the system becomes difficult to accommodate dynamic ad hoc creation and deletion of groups
Solution Approach 1:
The system transitions from static pre-programmed controller configurations to dynamic ad hoc group formation. Users can dynamically create, modify, and delete groups of audio players based on current needs without being constrained by predetermined settings. The controller allows real-time reconfiguration of which audio players belong to which groups, enabling flexible adaptation to changing playback requirements.
Solution Approach 2:
The system segments the control functionality into independent, user-configurable groups of audio players. Each group can be independently managed and configured, allowing users to create multiple overlapping groups with different compositions. This segmentation enables flexible group management where players can belong to multiple groups simultaneously, and groups can be created or deleted without affecting the entire system.
2Ease of operation
If the audio volume of audio players in a traditional multi-zone audio system is adjusted one at a time, then individual player control is maintained, but the operation becomes inconvenient and the audio environment becomes non-homogeneous
Solution Approach 1:
The system merges the volume control functionality for multiple audio players within a group into a single unified control operation. When a group is formed, the controller provides a master volume control that simultaneously adjusts the volume of all audio players in that group, eliminating the need for individual adjustments and ensuring homogeneous audio levels across the group.
Solution Approach 2:
The controller is designed with universal control capabilities that can operate at multiple levels: individual player control, group control, and system-wide control. The same controller interface and control mechanisms can be used to manage different numbers and combinations of audio players, providing ease of operation regardless of the specific configuration or number of players being controlled.
3Adaptability or versatility
If a centralized location provides audio sources to multiple audio players, then source sharing is enabled, but a cross-bar type device is required to prevent the audio source from going to other audio players that may be playing other audio sources
Solution Approach 1:
The system implements dynamic source routing where the connection between audio sources and audio players is not fixed but can be changed in real-time. The controller dynamically routes audio sources to specific groups of players based on current playback requirements, allowing the same source to be shared with different groups at different times without requiring complex physical switching infrastructure.
Solution Approach 2:
The controller acts as an intermediary between audio sources and audio players, managing the routing and distribution of audio signals. Rather than requiring direct physical connections and complex cross-bar switching devices, the controller mediates the audio signal flow, intelligently routing sources to appropriate players or groups based on active group configurations and playback requirements.

AI summary
Techniques for controlling zone group and zone group characteristics such as audio volume in a multi-zone system are disclosed. The multi-zone system includes a number of multimedia players, each preferably located in a zone. A controller may control the operations of all of the zone players remotely from any one of the zones. Two or more zone players may be dynamically grouped as a zone group for synchronized operations. According to one aspect of the techniques, a zone group configuration can be managed, updated, modified via an interactive user interface provided in a controlling device. The zone group configuration may be saved in one of zone players. According to another aspect of the techniques, the audio volume control of a zone group can be performed individually or synchronously as a group.
