The invention relates to a system for realizing the television service via mobile terminal, which includes: a network service center of digital television broadcasting, a mobile television broadcasting-program distribution sell (MTB-PDS), a mobile video broadcasting-terrestrial transmission sell (MTB-TTX), a mobile video broadcasting-mobile station (MTB-MS). The transmission method shows as follow: the network serving center reuses different digital-programs as transport-streams to transmit to MTB-PDS, MTB-PDS converts the transport-streams into different programs and allocates them to different broadcast-streams to transmit to MTB-TTX, and MTB-TTX broadcasts the received different broadcast-streams through different sub-channels of empty broadcasting channels. The receiving method shows as follow: MTB-MS remains on the frequency point of the broadcasting carrier frequency of television service via mobile terminals, and the program data of the sub-channels of the empty broadcast channel can be received. |
