Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing audio systems require manual adjustment of volume settings using a remote control, which can be inconvenient, especially when the remote is not readily available.

Innovation Solution

A system that detects adjustment events through analysis of audio data signals or command signals, allowing for automatic calibration of media presentation devices or microphones, including adjusting volume settings or gain settings based on detected events, and transmitting commands to adjust these settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustment of volume settings using a remote control is used, then the user can adjust audio settings, but the user experience deteriorates when the remote is not readily available

Engineering Contradiction:

ImproveEase of adjusting volume settingsVSAvoidTime to locate and use remote control

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system automatically detects adjustment events from audio signals or command signals and self-adjusts the volume and gain settings without requiring manual intervention or a remote control, allowing the device to serve itself

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical remote control system with an automatic detection and adjustment system that uses audio signal analysis to trigger volume and gain adjustments, eliminating the need for physical remote interaction

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If automatic calibration via event detection is implemented, then ease of operation improves, but device complexity increases

Engineering Contradiction:

ImproveAutomatic volume and gain adjustmentVSAvoidComplexity of signal analysis and event detection system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system processes both audio data signals and command signals through the same event detection mechanism, allowing a single detection system to handle multiple types of adjustment events and control different devices (media presentation devices and microphones) with the same infrastructure

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Systems, methods, and computer readable storage medium are described for media presentation device or microphone calibration via event detection. An adjustment event is detected based on an analysis of a received signal. A determination to adjust at least one of a volume setting of a media presentation device or a gain setting of a microphone is made based at least on the detected adjustment event. Responsive to the determination, a first command is transmitted to at least one of the media presentation device or the microphone. In an aspect, the received signal is an audio data signal received from a listening device. In another aspect, the received signal is a command signal received from a second computing device via a network interface, the command signal comprising instructions to adjust the volume setting of the media presentation device, the second computing device remotely located and associated with a second user.
