Abstract EN
An ultrasonic sensor-based personalized multichannel audio rendering method is proposed for multiview broadcasting services.
Multiview broadcasting, a representative next-generation broadcasting technique, renders video image sequences captured by several stereoscopic cameras from different viewpoints.
To achieve realistic multiview broadcasting, multichannel audio that is synchronized with a user’s viewpoint should be rendered in real time.
For this reason, both a real-time person-tracking technique for estimating the user’s position and a multichannel audio rendering technique for virtual sound localization are necessary in order to provide realistic audio.
Therefore, the proposed method is composed of two parts: a person-tracking method using ultrasonic sensors and a multichannel audio rendering method using MPEG Surround parameters.
In order to evaluate the perceptual quality and localization performance of the proposed method, a MUSHRA listening test is conducted, and the directivity patterns are investigated.
It is shown from these experiments that the proposed method provides better perceptual quality and localization performance than a conventional multichannel audio rendering method that also uses MPEG Surround parameters.
