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”
