We learned :The importance of broadcasting during a disaster


We learned :The power of one-seg mobile TV

The ISDB-T one-segment service sends TV programs to mobile phones, car TVs. This can be an important safeguard for life and property in times of emergency even when no electricity is supplied.

Policemen saved 40 lives with one-seg mobile TV alarm!Two new policemen got a tsunami warning alarm from the passengers mobile phone with TV when checking if everyone is fine in the train. They quickly decided to lead the 40 passengers to the hill to avoid the disaster of tsunami. All passengers were safely evacuated from the tsunami area before the tsunami struck the train.
