Mirage Extender can be used in 2 ways.

First it can be used as an extension to your Mirage player on your android device.
It can also be used as a generic Airplay server for your Airplay compatible players (like your iOS devices). For those devices it currently only supports video streaming.

How to use:
Just launch Mirage Extender on your Google TV and start streaming from your Airplay compatible client.
