Sorry, I didn't see that you posted more info.
Google Slingbox.
In a nutshell, it is a device that allows you to access your TV/DVR from anywhere using a computer/cell phone/etc.
So you would have the Slingbox at home with your regular TV and DVR setup connected through your highspeed router.
When away from home you can "connect" with the set up at home, control TV channels, watch and record from your DVR, etc.
