Image Display Audio Volume Adjustment for Immersive Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When an image display apparatus and a sound output device simultaneously output sound, a sense of difference is generated between the sound outputs, disrupting immersion for users.
Innovation Solution
An image display apparatus with a signal processing device that outputs different audio signals to the image display apparatus and the sound output device, adjusting the volume levels to match or differ based on output power information or additional offset information from the sound output device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the image display apparatus and sound output device simultaneously output sound, then the sound output power is increased, but a sense of difference is generated between the sound outputs, disrupting immersion
Solution Approach 1:
The signal processing device dynamically adjusts the volume level parameter of the audio signal output to the image display apparatus based on the output power level of the sound output device. When the sound output device operates at high power, the image display apparatus reduces its volume level to prevent creating a sense of difference, thereby maintaining immersive sound experience while preserving high sound output power capability
2Reliability
If the image display apparatus solely outputs sound, then stable sound is maintained, but the sound output power is limited
Solution Approach 1:
The system merges the audio output functions of the image display apparatus and the sound output device into a coordinated operation. The signal processing device manages both devices simultaneously, allowing the sound output device to provide high power sound output while the image display apparatus contributes to the overall audio experience, thereby achieving both high power and stability through cooperative operation

AI summary
An image display apparatus is provided. The image display apparatus of the present disclosure comprises: a display; an audio output device; an interface to exchange data with an external sound output device; and a signal processing device which, in a simultaneous sound output mode, configured to output a first audio signal to the audio output device and a second audio signal to the sound output device, and in a single sound output mode, configured to output a third audio signal to the audio output device, wherein a volume level of a first sound based on the first audio signal, which is output from the audio output device, is different from a volume level of a third sound based on the third audio signal which is output from the audio output device. Accordingly, it is possible to reduce the sense of difference in case in which the sound output device and the image display apparatus simultaneously output sound.
