Playback Device Base for Placement-Based Zone Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media playback systems lack the ability to dynamically adjust playback configurations based on device placement, limiting the flexibility and functionality of networked audio devices.
Innovation Solution
Playback devices can acquire and modify zone properties from device bases, allowing them to join or leave zones, change roles within zones, and synchronize playback with other devices based on their placement, using a method involving processors, data storage, and network interfaces to manage zone assignments and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If playback devices use fixed zone assignments, then system stability is improved, but adaptability deteriorates
Solution Approach 1:
The patent implements dynamic zone assignment where playback devices automatically acquire zone properties from device bases they are placed on. The system transitions from static, pre-configured zone assignments to dynamic, placement-based assignments. When a playback device is placed on a device base, it automatically detects the base's identifier and acquires the associated zone property, enabling the system to adapt to changing physical configurations without manual reconfiguration.
2Adaptability or versatility
If playback devices can dynamically join/leave zones, then adaptability is improved, but system complexity deteriorates
Solution Approach 1:
The patent implements self-service automation where playback devices autonomously manage their own zone assignments. When a playback device is placed on a device base, it automatically detects the base's identifier through wireless communication, queries the zone property associated with that identifier, and joins the appropriate zone without user intervention. The system handles zone membership changes, property acquisitions, and configuration updates automatically, eliminating the need for manual zone management while maintaining system coherence.
3Adaptability or versatility
If multiple device bases are supported, then adaptability is improved, but difficulty of detecting and measuring deteriorates
Solution Approach 1:
The patent implements a feedback-based identification system where device bases transmit their unique identifiers wirelessly to playback devices when in proximity. The playback device receives the identifier feedback, uses it to query the appropriate zone property from the network, and automatically configures itself accordingly. This feedback mechanism simplifies the detection process by having the base actively provide its identifier rather than requiring the playback device to scan or detect passive characteristics.
Data Source
AI summary
Example techniques may involve a playback device modifying its playback configuration when the playback device is placed onto a device base. In an example implementation, the playback device may receive, via an 802.15-compatible radio of one or more network interfaces, one or more packets comprising data representing an identifier of the first device base. After receipt of the one or more packets, the playback device queries a database for state information corresponding to the identifier of the first device base and modifies a playback configuration of the playback device from a first configuration to a second configuration based on the queried state information corresponding to the identifier of the first device base.
