Playback Device Configuration via Aggregated Calibration Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media playback systems lack efficient methods for calibrating playback devices to achieve optimal sound quality across diverse environments and user preferences.
Innovation Solution
A computing device aggregates calibration data from multiple playback devices to determine updated configuration information, including target frequency response curves, based on user behaviors and device characteristics, and transmits these updates to the playback devices for improved sound quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If calibration data is collected from multiple playback devices to determine updated configuration information, then sound quality is improved, but device complexity increases
Solution Approach 1:
A computing device acts as an intermediary to aggregate calibration data from multiple playback devices, process the data to determine updated configuration information, and distribute the updates back to the playback devices. This centralizes the complex data processing functionality externally, allowing individual playback devices to remain relatively simple while still benefiting from crowd-sourced calibration improvements.
2Manufacturing precision
If calibration data is aggregated from a large number of playback devices, then listening experience is enhanced, but data processing requirements increase
Solution Approach 1:
The patent extracts only the essential calibration data elements needed for determining configuration updates from the aggregate data set. The computing device processes the collected calibration data to identify trends and determine updated configuration information, extracting only the necessary updates rather than processing and distributing all raw calibration data, thereby reducing data processing requirements while maintaining listening experience enhancement.

AI summary
An example computing device is configured to perform functions including receiving calibration data corresponding respectively to a plurality of playback devices, where each playback device in the plurality of playback devices is located in a respective playback environment other than a first playback environment. The functions also include receiving playback device characteristic data respectively indicating at least one playback device characteristic for each playback device of the plurality of playback devices. The functions also include, based on at least the calibration data and the playback device characteristic data, determining updated playback device configuration information and transmitting data indicating the updated playback device configuration information to a given playback device located in the first environment.
