The bandwidth of a DVB-S stream (or is that DVB-S2? Eh. Let’s not complicate this) is about 27Mbit/sec, and that is enough to offer like ten or so standard resolution tv channels.
To everyone. The sender cannot tell how many receivers that are currently actively receiving the signal. And it doesn’t matter, because it’s a one-way broadcast.
And the viewer is never going to be able to tell if the signal is delayed or not, which means that the build in delay in a satellite link doesn’t matter for the perceived quality of the service.
With an internet connection, however, things get more complicated. For starters, pretty much EVERY user expect to get close to 27Mbit all by themselves, which means that you have to fiddle with making the bandwidth that you could have used for EVERY customer available for just the one; it’ll cost a lot more to make that happen for the service provider.
And don’t get me started on the difficulty in ensuring that a customer is able to SEND data so that the internet connection actually works.
Standard satellite tv broadcasting CAN be used for satellite internet, but is NOT particular good at it. it can, and is, however pretty good at feeding a control system with data that it does not need to respond to: power companies and other utility users sometimes use those kinds of feeds for some of their control systems. Usually as a redundancy in case the two-way communication goes down.
