What is needed to watch NASA TV?

Hello everyone!



I'm not too sure that I arrived at the right group for the subject, so
please direct me if I'm in the wrong place.



Basically, what I'm trying to accomplish is to get the minimal set of
equipment required to watch NASA TV. Having digital cable service from
Comcast, I see no other reason to put a satellite dish up but to get NASA TV
which, apparently, Comcast does not re-broadcast in their network. Therefore
I would like to get as little equipment as possible and was wondering if
some satellite TV pros or seasoned users here can post about their setups
and what could be considered the minimum required hardware for the task.



Thanks in advance!
