I need the IEEE paper on:

Satellite Direct-to-Home
Dulac, S.P. Godwin, J.P.
DirecTV, El Segundo, CA, USA;

Any related papers, books will also be helpful.

Why Direct-to-Home TV is now popular? Can you describe it's system functions?

How can I know the details about this system?

Bye

Very popular now because many hi-definition channels available. Quality is higher than cable bacause they have more bandwidth so use less compression. They transmit in the Ku and Ka band.
Here is a good summary:
