FINAL COMMENTS
But what we want...
 This first experience puts together people in
Natal-Brazil and Miami-EUA watching the
same program at the same time, so it´s
possible!
 It was implemented to run over the Java TV
platform, so it runs in set-top boxes and
digital TV sets
 Here is a way to include people in the
“information society”
FINAL COMMENTS
 Interactive TV is an interesting
market for advanced applications
with digital video.
 Now our main goal is putting people
together for cheering but we also
can have people working or learning
using the same idea.
