Digital Terrestrial Television according to ISDB-T

Abstract

The Japanese answer to digital terrestrial television is the ISDB-T (Integrated Services Digital Broadcasting — Terrestrial) standard which was adopted in 1999, quite a long time after DVB-T and ATSC. This delay made it possible to take into account also the experience gained with the older standards. Unlike ATSC, where a single-carrier method is used, it was decided (correctly) for ISDB-T to use an OFDM multicarrier system as in DVB-T. ISDB-T is even more complex than DVB-T; presumably, it will also be more robust because of the greater interleaving with time. Since it has only been introduced relatively recently, however. The author does not have enough real practical experience in this regard to express an opinion. The first pilot station was installed on the Tokyo Tower and overall, ISDB-T started with eleven pilot stations throughout Japan.
