Yamaha has just successfully tested Infosound a way of transmitting URL’s from a TV to a mobile phone high-pitched sound frequencies inaudible to humans.
The Yamaha Infosound system uses frequencies above 18kHz for 80bps short-range data transfer and the system was tested via a live demo on Japanese digital TV network RCC in the early hours of this morning.
Yamaha is hoping that the new technology can be used to distribute website information from TV or radio, as well as to provide information in museums for visitor guides, exhibits information and maybe distributing coupons and other discount vouchers for retailers.
To be able to receive the URL’s send via the audio you will need a free iPhone app available here.
