During the transition period from analog TV to digital TV, both analog and digital TV programs are simulcasted.

The bandwidth of analog TV channel and digital TV channel must be the same.

A 6MHz bandwidth is assigned to one analog TV channel in South American countries as well as in Japan and the USA.

ISDB-T is the most popular system in countries where the bandwidth of one analog TV channel is 6MHz. 8 TVTV ChannelChannel SeparationSeparation ２２ MICMIC

Reason for adopting ISDB-T in Brazil

○ The channel separation of Brazil is ６MHz.

○ Brazil confirmed the advantage of ISDB-T by fair technical tests.

○ ISDB-T has the highest robustness to interference and can provide a mobile reception service.

○ Only ISDB-T can provide stationary and mobile reception services using the same TV channels and transmitters. 11 MICMIC

1997 ・Technical Standards for DTTB were established in E.U (DVB-T) and U.S.(ATSC)

1998 ・DTTB started in E.U (DVB-T) and U.S.(ATSC)

1999 ・Technical Standards for DTTB were established in Japan (ISDB-T). ・Support center for R&D of DTTB in Japan opened. (Shared use of facility, Organization of Communications and Broadcasting)

2000 ・Technical standards for Digital Terrestrial Sound Broadcasting were established in Japan. ・Planning of DTTB station channels.

2001 ・Development of institutions for digitization of Terrestrial Television Broadcasting. (Revised part of Basic Plan Popularization of Broadcasting and Use of Broadcasting Frequency)

2003 ・DTTB started in Japan (in three metropolitan areas). ・Start of trials for practical application of Digital Terrestrial Sound Broadcasting in part of Kanto and Kinki areas.

Because almost component of digital television receivers are same. As for the difference depend on DTTB systems is just modulation part which is negligible against price of TV set. As proof, price of the television receivers are same among PAL, NTSC and SECAM.

¾ Digitizing broadcasting consists of not only upgrading existing analog TV systems but also achieving attractive broadcasting service is the key to expand digital terrestrial TV for viewers.

¾ ISDB-T makes it possible to receive SDTV or HDTV while moving and provides the chance for enjoying new broadcasting service to users.

¾ ISDB-T can provide a “free” mobile TV reception service like ordinary TV broadcasting.

→ ISDB-T can be the most suitable system for expanding digital terrestrial TV .
