Abstract (en)

[origin: EP1841106A2] The present invention discloses a DAB-compatible transmitting method for terrestrial mobile multimedia broadcasting in which service type of multimedia broadcasting is predefined to be including terrestrial mobile multimedia broadcasting (T-MMB) service, the method comprises the steps of receiving multimedia broadcasting service data and performing sequentially source coding and channel coding on said service data according to their service type; embedding the encoded data into the main service channel (MSC) of the system in a time division multiplex mode, identifying accordingly information on subchannel, etc. corresponding to the service data in the fast information channel (FIC) of the system, and performing channel coding on the data in FIC; performing channel modulation, OFDM modulation and radio frequency (RF) modulation on the channel-modulated data of FIC, MSC according to the transmission mode and the channel modulation scheme, and then sending them out. With the invention, it is possible to effectively transmit multiple types of multimedia broadcasting service data in a mobile environment. The invention also discloses a DAB-compatible system and reception method for terrestrial mobile multimedia broadcasting.
