Zone Player Volume Interface for Synchronized Group Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media playback systems lack intuitive and efficient methods for controlling playback volumes across multiple zone players, particularly in forming and managing playback groups, which can lead to inconsistent audio experiences.
Innovation Solution
A user interface is provided that simultaneously displays volume indications and selectable icons for each zone player, allowing users to control individual or group volumes, and transmit commands to selected players for synchronized playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user interface displays individual volume controls for each zone player, then ease of operation is improved, but device complexity increases due to multiple separate controls
Solution Approach 1:
The patent combines multiple individual volume controls into a unified group volume control interface. When zone players are selected for a group, a single group volume indicator and control mechanism is displayed, allowing users to adjust the volume for all selected players simultaneously rather than controlling each player's volume separately through multiple independent controls.
Solution Approach 2:
The interface dynamically switches between displaying individual volume controls and a unified group volume control based on the selection state of zone players. When players are selected for grouping, the interface transitions to show group-level control options, providing adaptive control mechanisms that change based on the operational context and user selections.
2Adaptability or versatility
If the system provides separate volume control for each zone player, then adaptability is improved, but ease of operation deteriorates due to multiple separate controls
Solution Approach 1:
The patent merges individual volume control capabilities into a unified group volume control mechanism. Users can select multiple zone players and then adjust a single group volume setting that applies to all selected players simultaneously, maintaining the ability to control individual players while simplifying the operation through consolidation.
Solution Approach 2:
The group volume control interface serves multiple functions: it controls volume for all selected players simultaneously, maintains individual player volume settings when not in group mode, and provides a unified control mechanism that reduces the number of separate controls needed while preserving adaptability for different playback scenarios.

AI summary
An example method involves providing an interface that simultaneously displays an indication of a respective volume corresponding to each of at least two zone players and displays a respective selectable icon corresponding to each of the at least two zone players. Each respective selectable icon indicates whether the corresponding zone player has been selected for a group, and at least one of the respective selectable icons indicates that a respective zone player has been selected for the group. The interface further displays an indication of a group volume associated with the at least one selected zone player. The method further includes receiving a command to change at least one of a respective volume of one or more of the at least one selected zone player or the group volume, and transmitting an indication of the received command to one or more of the at least one selected zone player.
