It seems Apple has picked up yet another patent application. This time, the focus appears to be on remotely streaming your iTunes library at home onto your iPhone or iPod Touch while you’re out and about via WiFi or a cellular network.
As it stands right now, you have to physically put your songs, videos or what have you onto your iPhone or iPod during the synching process. What this patent proposes is that you would only need to transfer a directory of the files in your library to the external device. When you go to play a song, it would then access your library at home over WiFi or a cell network and stream the content to your phone.
There’s no word on when or if this technology will ever be put into place, but something similar is currently used on Apple TV and Airport Express.
