DMB ('''Digital Multimedia Broadcasting''') is a digital transmission system for sending data, radio and TV to mobile devices such as mobile phones. It can operate via satellite ( S-DMB ) or terrestrial ( T-DMB ) transmission. DMB is based on the Eureka 147 DAB standard and has some similarities with the competing mobile TV standard DVB-H . T-DMB is an ETSI standard (TS 102 427 and TS 102 428). T-DMB uses MPEG-4 Part 10 ( H264 ) for the video and MPEG-4 Part 3 BSAC or HE-AAC V2 for the audio. The audio and video is encapsulated in MPEG-2 TS. The stream is RS encoding and the parity word is 16 bytes length. There is convolutional interleaving made on this stream, then the stream is broadcast in data stream mode on DAB . DMB DEPLOYMENT Currently, DMB is being put into use in a number of countries. South Korea started S-DMB and T-DMB service in May 1 and December 1 2005 respectively. Some T-DMB trials are currently planned around Europe:
