Is it possible to transmit AV over a wifi network to a Windows based PC?

I have an Xbox 360 in my bedroom, connected to my (standard def) TV. I also have a laptop running Windows 7. Is it possible to use my home network to send the Xbox’s output across my home network so that i can sit outside and play it?

I know both the controller and the home network work out there so all i need is a way to get my xbox’s display to show up on my laptop.
