Hi guys, I'm making a website for a web based TV channel, so I'm assuming it will be heavy on bandwidth usage, but I'm no good at calculating bandwidth.

Couple of questions:

1. Assuming the site streams HD video 24 / 7 to 1000 people, how much bandwidth is that?
2. Where should something like this be hosted? The channel will have a fiber internet optic connection, but I don't know the limit on their bandwidth, would it be better to get their own server or host online?

In either case in question 2, any recommendations? I'm usually a regular web designer for minor businesses, so this is a new level.

Your help is appreciated.
