Is this possible on Time Capsule??

Hey guys, ive been looking for something sort of specific lately. i have lots of music, pictures, and videos on my macbook pro that i transfer onto a usb drive and plug into my ps3 to view on my tv. Ideally I would like to store all my media on the time capsule and leave it permanently hooked up to my ps3 via the ps3's usb drive. And then any new media I would like to transfer from my macbook to the time capsule via wifi, keeping my MacBooks hd empty.

If the time capsule cant do this can you guys recommend anything for my specific situation?

thanks.
