ATV is the largest commercial television station in Austria, according to Wikipedia. It was formed back in 1997, meaning that it is a quite young TV station. Originally it was known as Wien 1, but then as they started broadcasting in all of Austria, the name was changed to ATV.
ATV is a channel that produce a great amount of its content themselves. That means that as you watch ATV you will watch a whole lot of programs and productions produced by the channel itself. These programs can of course be seen online, but if you want to see them you will not to get yourself an IP in Austria.
The problem is that if you try to watch ATV.at and their Mediathek from outside Austria, you will be met by a screen telling you that it can only be aired within Austria. You will therefore need to make them believe that you are located in Austria, and the way to do that is by acquiring an Austrian IP, which will make all former limitations go away, and open the doors and the streams of your favorite ATV streams to you, wherever you are in the world.
Watching ATV with IPVanish
The way of getting that IP address in Austria is by using a VPN provider. There are several such providers on the market, but the best ones if you are interested in an IP address in Austria is probably IPVanish or HideMyAss. If you compare prices IPVanish is a bit cheaper if you need a one month or a three month subscription, but the differences are very small, so it does not really matter. During some tests I have made I got better speeds with IPVanish, but it should not really matter, so just visit both websites and make a subscription to the VPN provider that looks the best to you.
HideMyAss has a 30 day refund policy, while IPVanish has a 7 day refund policy. Maybe that info will influence you as you decide which VPN provider to use.
