Sharing enthusiasm between remote sites
Applause coding for bi-lateral immersive sharing
Abstract
Live performances are increasingly appreciated using popular commercial audiovisual transmission systems, such as live viewing systems. We developed a reality enhancement method for the live viewing system that transmits applause sound which occurred at the viewing site to the live venue. We named it APRICOT (APplause for Realistic-Immersive COntents Transmission) system. This presentation shows an applause sounds detection, transmission, and generation system. At actual live viewing, the devised system successfully detected applause sounds by using real-time signal processing approach. Then, the sound level is converted into the meta-data, which is transmitted to live venue. At the live venue, natural applause sound is generated by using recorded hand-clapping sound seeds. This applause synthesizer is based on the hand-clapping model. The subjective experiments show that APRICOT system achieves more realistic live viewing services.
