Can someone please explain the itunes feature on N900

I started reading some brief reviews of the router and itunes server was listed as a feature.  I’m assuming this is with your media connected to an external hard drive.

My question is can ios devices like Apple TV access the music and movies stored?  Right now I need a computer on with itunes installed to be able to access the media.

Thank you.

That will depend only if the Apple TV supports connecting to none IOS devices 

the server will be accessible to all computers to play itunes media from the N900
