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 TVchannel 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.

Reason for adopting ISDB-T in Brazil
Brazil confirmed the advantage of ISDB-T by fairtechnical tests.
ISDB-T has the highest robustness to interferenceand can provide a mobile reception service.
Only ISDB-T can provide stationary and mobilereception services using the same TV channels
and transmitters.
The channel separation of Brazil is 6MHz.

There is no difference in price of the television
receivers among DTTB systems.Because almost component of digital television receivers are same.
As for the difference depend on DTTB systems is just modulation part which isnegligible against price of TV set.
As proof, price of the television receivers are same among PAL, NTSC and SECAM.
Price of the television receivers is depend on functions.e.g. High Definition TV, Multi SD, Date broadcasting, interactive function. etc
