Multi-Zone Playback Scene Configuration for Synchronized Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media playback systems lack the ability to easily create, store, and instantiate multi-zone group scenes that allow for synchronized playback across multiple zones in a household or other environments, limiting the flexibility and convenience of digital audio experiences.
Innovation Solution
A media playback system and method that enables the creation, storage, and instantiation of multi-zone group scenes through a controller interface, allowing configuration of multiple zone groups with specific settings and parameters, which can be stored locally or on external devices, and transmitted to zone players for synchronized playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple zone groups are configured for synchronized playback across different rooms, then the audio playback versatility and user experience are improved, but the system complexity and difficulty of management increase
Solution Approach 1:
The system pre-configures multiple zone groups with specific playback settings, scene names, and synchronization parameters before actual use. Users can define multi-zone scenes in advance that automatically configure playback across selected zones, eliminating the need for manual real-time setup and reducing operational complexity during actual audio playback scenarios.
Solution Approach 2:
The system creates reusable scene configurations that can be copied and instantiated across different zone groupings. Once a multi-zone scene is configured, it can be replicated and applied to different combinations of zones, allowing users to leverage the same playback configuration across multiple scenarios without reconfiguring each time, thus reducing system complexity while maintaining versatility.
2Ease of operation
If zone groups are configured and stored locally or externally, then the ease of recreating audio configurations is improved, but the device complexity and storage requirements increase
Solution Approach 1:
The system extracts and separates scene configuration data from the main playback control logic, storing scene definitions, zone groupings, and playback parameters as independent configurable objects. This extracted configuration data can be stored locally in device memory or externally on connected storage devices, allowing easy recreation of audio configurations without complicating the core playback system architecture.
Solution Approach 2:
The scene configuration system is designed to be universal, supporting multiple storage locations (local memory, external storage, cloud-based storage) and multiple retrieval methods. The same scene configuration framework can be applied across different device types and storage configurations, providing ease of operation without requiring separate complex systems for each storage option.
3Measurement precision
If configuration data is transmitted to zone players for instantiation, then the synchronization accuracy across zones is improved, but the network bandwidth consumption and system complexity increase
Solution Approach 1:
The configuration data transmission is segmented into essential synchronization parameters (timing offsets, sample rate synchronization data, buffer configuration) and non-essential playback parameters (volume levels, equalization settings, source selection). Only the critical synchronization data is transmitted to zone players to ensure timing accuracy, while less frequently updated parameters are either cached locally or transmitted less frequently, reducing overall network bandwidth consumption while maintaining synchronization precision.
Data Source
AI summary
The examples provided herein involve multiple groups in a playback system. An example method involves, based on receiving one or more inputs defining a zone scene of a media playback system that comprises a plurality of zone players, defining configuration data corresponding to the zone scene, wherein the configuration data comprises an identification of at least a first zone player and a second zone player. The method further involves causing a remote computing device to store the configuration data and presenting a user-interface element that, when selected via the user interface, causes the zone scene to be invoked. The method additionally involves, in response to receiving an input indicative of a selection of the user-interface element, causing the remote computing device to invoke the zone scene at the media playback system such that the first zone player and the second zone player playback audio content in synchrony.
