Summary:In the Integrated Services Digital Broadcasting-Terrestrial Sound Broadcasting (ISDB-T_SB)transmission system, a narrow-band orthogonal frequency division multiplexing with one or three segment(s) is adopted. It is robust against multipath interferences in urban radio wave transmission. In addition, it is capable of mobile reception because of time interleaving. A transmission bandwidth of 432 kHz for one segment is narrow enough in order to allocate channels flexibly, and the "connected transmission" scheme, which allows multiple segment transmission with no guard band, is a highly efficient usage of the frequency resource. The ISDB-T_SB transmission system is consistent with ISDB-T, hence it enables a common receiver for partial reception of ISDB-T, digital television broadcasting. In this paper, the ISDB-T_SB transmission system,especially the differences from the ISDB-T transmission system, is introduced,and the current status of the ISBD-TSB digital terrestrial sound broadcasting service is shown.
