Remote Streaming IPad from Time Capsule

Hi:
I have a Time Capsule device with several movies, photos, and media saved inside.
I have no problem watching all them by wifi from my IOS devices (Iphone, Ipad…) employing Infuse 4.
I wonder if it should be possible to watch them far from home, remotely; I mean by streaming, FTP or whatever…
Even more, I cann´t find a video explaining this issue.
Thank you in advance.
