Try not to get hung up when you don't know all the words. In this phrase 'drive' means to be in control the users choose the direction. So, unlike normal TV where what is shown is out of your control, in this case the viewer decides the content. Like in a car, the person who drives decides the direction.
Mobile entertainment- when you watch TV you are usually at home, you are not mobile, but now you can access so much stuff by mobile phones etc that the enterntainment is 'mobile' - it goes with you.
Hope that helps. When you get stuck like this, try to think around the problem. Think of some of the things it could mean, and it's probably the most sensible one.
