Digital multimedia broadcasting (
DMB) is a digital
radio transmission technology developed in
South Korea as part of the national
IT project for sending multimedia such as
TV,
radio and
datacasting to
mobile devices such as mobile phones, laptops and GPS navigation systems. This
technology, sometimes known as
mobile TV, should not be confused with
Digital Audio Broadcasting which was developed as a research project for the
European Union. DMB was developed in South Korea as the next generation digital technology to replace FM radio, but the technological foundations were laid by Prof. Dr. Gert Siegle and Dr. Hamed Amor at Robert Bosch GmbH in Germany. The world's first official mobile TV service started in South Korea in May 2005, although trials were available much earlier. It can operate via
satellite (
S-DMB) or terrestrial (
T-DMB) transmission. DMB has also some similarities with the main competing mobile TV standard,
DVB-H.
