Bert,
Then I misunderstood Olivier when he referred to "the document" when asking about 1080@60p, and his email quoted Jonas' link to the Brazilian .pdf of a powerpoint presentation as the 'document.'
In that .pdf outlining the Brazilian system, it says Brazil will use H.264 exclusively for all video, SD and HD, for their DTTB. I mistakenly thought Olivier was asking if Brazil would use 1080@60p.

I would imagine it is 1080@60p since they are using

Not necessarily. I searched around and never saw any mention of any HDTV
modes greater than 1080i, in Portughese sites. Also never any mention of
bit rates greater than 19 Mb/s. Also, I did see mention of being able to
carry two HD programs at the same time, supposedly thanks to AVC,
although that can even be done with MPEG-2 compression.

I don't think HDTV is high on their priority list initially, though, but
that could change as HD sets become cheap and commonplace.

I also saw some disgruntled posts where people said that SBTVD is
nothing but ISDB-T.

And a whole lot of talk about social implications of DTV, and the like.
All that verbiage one sees at the beginning of these DTV programs, for
whatever reason. Happens in all countries. Then it dies down as people
get tired of hype and reality sinks in.
