Digital Multimedia Broadcasting facts for kids
Digital multimedia broadcasting, or DMB, is a cool technology that lets you get digital signals on your mobile devices. Think of it like a special way to send TV shows and radio to your mobile phone or other gadgets.
This technology was created to replace older ways of sending radio signals. DMB can send a lot more information using the same radio waves. This means it can send not just sound, but also video that looks as good as a DVD!
DMB is based on a European standard called Eureka 147 DAB. There are other similar technologies too, like DVB-H. South Korea has been a big part of developing DMB. Satellite DMB broadcasting actually started in Japan before South Korea.
DMB in South Korea
In South Korea, DMB comes in two main types:
- Earthly DMB: This is like regular TV or radio. It's usually free to watch or listen to.
- Satellite DMB: This type uses satellites to send signals. You usually pay a monthly fee for this service.
In South Korea, a company called TU Media broadcasts satellite DMB.
You can get DMB on different devices. You might attach a DMB receiver to your car. Or you can buy a mobile phone that already has DMB built-in. There are also small portable receivers you can carry around. You can even connect a DMB receiver to your computer monitor.
For a while, earthly DMB and satellite DMB devices were not compatible. This meant you needed a separate device for each type. However, some newer phones can now receive both.
