Digital Multimedia Broadcasting
Digital multimedia broadcasting, or DMB, is a technology that allows sending digital signals to mobile devices, such as mobile phones. This makes it possible to listen to radio or watch television on such devices. It was developed in South Korea.
This technology was developed to replace analog radio broadcasting. It can transmit not only sound data but also DVD quality movie data.
DMB is based on Eureka 147 DAB standard which is the European standard. DMB meets the ETSI standard (TS 102 427 and TS 102 428). Now, the Republic of Korea can exercise its rights as the source of the DMB technology; the satellite DMB broadcast first began in Japan, then in the Republic of Korea. On March 13, 2004, TU Media, playing a leading role in business, and satellite DMB launched the world's first satellite with Japan's partner, MBCo DMB 'hanbyeol'. However, in the Republic of Korea, the selection process for operators was long and put off service, so MBCo in Japan became the first DMB country to start the full service with all 40 channels from October 19, 2004.
DMB can be received when you attach a DMB receiver to the vehicle, or buy a mobile phone that has the ability to receive DMB, a personal portable receiver, or a receiver which outputs to the monitor when connected to a personal computer. But there was a problem that the satellite DMB and terrestrial DMB are not compatible with each other, so users should purchase each terminal separately. However, Samsung opened the door to watch satellite DMB and terrestrial DMB with one terminal by coming out with SPH-B4100. But TU Media, the satellite DMB service provider, rejected the plan, so the possibility of the activation of these two-way receiving terminals is currently unclear.
Comparing with terrestrial digital television and digital satellite broadcasting, terrestrial digital television has a clear screen even though you are on high-speed vehicles, but it is limited in range and lacks channels, which are disadvantages.
