Playback Device Room Naming for Multi-Controller Zone Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media playback systems lack efficient methods for dynamically controlling and managing playback devices across multiple zones with varying attributes, leading to inconsistencies and user confusion.
Innovation Solution
The system employs a method where a first set of device attributes is used by a controller application or cloud server to control playback devices, and a second set of device attributes is identified and selected based on the first set, allowing for the storage and use of selected attributes to control playback device functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different controller applications are used to control playback devices, then functionality and control options increase, but device complexity and user confusion increase due to inconsistent naming conventions
Solution Approach 1:
The patent implements a universal naming convention system that allows multiple controller applications to control playback devices using consistent room names and device attributes. This enables different controller apps to interoperate seamlessly while maintaining a single source of truth for device identification and room association, thus providing versatility without increasing complexity
Solution Approach 2:
The system introduces an intermediary layer (the unified naming convention and attribute system) that mediates between multiple controller applications and the playback devices. This intermediary standardizes how devices are identified and controlled, allowing diverse controllers to work together without directly creating complexity at the device level
2Measurement precision
If device attributes are dynamically selected and stored, then control precision and consistency improve, but processing time and system complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-establishing unified naming conventions and device attribute structures before multiple controller applications need to access them. Room names and device attributes are standardized in advance, allowing rapid retrieval and consistent identification without requiring complex processing at the moment of control
Solution Approach 2:
The patent implements dynamic parameter selection where device attributes are selected and stored based on specific control needs. The system efficiently manages attribute retrieval by changing parameters only when necessary, optimizing the balance between identification precision and processing time through selective attribute access

AI summary
Systems and methods for use in a media playback system comprising one or more playback devices are disclosed, where a playback device has a corresponding first set of device attributes used by a first controller application. The methods include: (i) identifying a second set of device attributes used by a second controller application to control the playback device, (ii) selecting a second device attribute for the playback device from the second set of device attributes based at least in part on a first device attribute; (iii) storing the selected second device attribute in the first set of device attributes; and (iv) controlling at least one function of the playback device using the selected second device attribute.
