A digital media hub from Microsoft that streams photos, audio and video from a Windows Media Center PC to the TV or home theater over a wired or wireless network connection. Connected to the TV set like a set-top box, the Media Center Extender (MCX) streams audio and video from the Media Center PC while other applications can be run at the same time.
Multiple MCXs can be used in different parts of the home simultaneously, each receiving different output from the computer. For gamers, Microsoft's Xbox game console has a built-in MCX and can operate both as a gaming machine and digital media hub. See Windows Media Center
