I understand that televisions in Brazil can now display Libras (Brazilian
sign language). Does anyone on the list know how this is implemented? I
can see a few possibilities:

1. Existing closed caption text is translated to Libras by software in the
television.

2. Animation commands are transmitted to the television (perhaps using
EMBR or SiGML). These animation commands animate an avatar generated in
the television receiver.

3. A video stream of the sign language is transmitted.

Does anyone on the list know how this actually works?

THANKS!

Harold
