Brazilian DTV is scheduled to start Broadcast in December 2007 in São

As far as I am concerned, the ISDB-T modulation is the same. The most
significant modifications were in SI Tables and Middleware. The Ginga

But my bet is that 1-seg transmissions will be very popular here.
This is why I would like to start coding drivers for 1-seg devices.
