I purchased F1TV for this season and I gotta say, it is very cool.
A menu slides out on the right hand side of the screen. You can pick between two different broadcasts. The normal one and one they call international. It has a tracker option that is just a graphic of the track and it shows where each driver is on the track. It has a data page that shows the time for each sector. Each sector is broken down into smaller data bars that turn yellow/green/purple depending on the time. The last thing they have is driver cams. All drivers are available and when you select one you also get their unedited team radio.
Well worth the money.
