Is there a software for creating your own subscription based online streaming library?

I’m looking to create a subscription based service that will allow subscribers to pay $XX a month to have access to certain audio and video files via streaming. Is there an "out of the box" software that will do this? Any ideas? Thanks.
I’m not just looking for a subscription service only… I was thinking it would be a software because it would need a nice interface. Maybe something similar to an "iTunes" look, as far as organization, presentation and search-ability. Hope that clarifies a bit more.

You can do that on paypal. you do not need a software for it.
