Sat TV, Dish TV, D2H TV ; Sat Internet Diffs

I am new to this Forum, and also to Satellites.

I would appreciate if someone could educate me on the foll basic queries :

I would like to know the essential diff betn :
Satellite TV
Dish TV
Direct to Home TV

1) I thought that all 3 above TV Broadcasts were the same ; but I would like to know the main / unique diffs betn the 3 cases above.
Further, is there any diff betn the above 3 cases, when it comes to HD TV and 3D-HD TV Broadcast ?

2) In this website, I have seen mention of Satellite Internet for Broadband.
Currently, I have a BB Connection on my Phone Line using a Data Splitter.
In the case of Sat Internet, which authority sends the BB Bills ?

3) If we already have a Dish Antenna, LNB, DVR / STB etc connected to a TV, can we also opt for Satellite Internet using the same Dish and a spare output from the same LNB to the PC or the Wireless Router ?
If technically yes, then, what is the intermediate device between the LNB Output cable and the PC or the Wireless Router ?

4) Further, if one is using the Dish Antenna only for viewing Free FTA Channels (ie, not subscribed to any D2H TV Channels Provider), can he also get “Free” Sat Internet ! ? I know that this is probably not possible, but I would like to have some explanation / some analysis.

I separated the queries into 3 separate Thread Titles, so that there will be less Overlap between these sets of queries.
