INFOSOUND can transmit information through standard TV and PC speakers. It brings about a new form of communication that naturally augments conventional information transmission in areas ranging from entertainment content to advertising.

  • Because INFOSOUND uses a high-frequency band that differs from ordinary broadcast audio, it can be broadcast together with television audio channels with almost no effect on the sound source or almost silently by itself.
  • INFOSOUND does not require any special speakers. With an ordinary television and smartphone, viewers can experience a new form of broadcast without having to use any special devices.
  • INFOSOUND brings an immediacy to content sent with TV programs and can be displayed on a smartphone.
  • When content is distributed via broadcasts that have a large audience, content servers linked with the broadcasts can expect high traffic. This can be prevented by using INFOSOUND to avoid load concentration.


  • Display content linked to a variety program on viewer smartphones to create audience-participation type programs.
  • Send news as text to the smartphones of news-program viewers.
  • Send recipes linked to cooking shows for display on viewer smartphones.
  • Display product-purchase pages on the smartphones of viewers watching shopping programs.

Q. Is there any impact on people's health?

A. INFOSOUND uses sounds in high-frequency bands in the range of 18-20 kHz, and is inaudible to most people. In addition, joint research with a medical university confirmed that there is no observable increase in stress due to INFOSOUND audio signals at volume levels normally used in communication. INFOSOUND can be used with confidence in broadcasts targeting the general public.
