Streaming a video on iPhone and then storing it on the device

Question

I've been told that some apps have video streaming which streams initially and when completely downloaded the video is stored to the user's device for quick and internet-free subsequent viewing.

Firstly, is this possible? Secondly, could you point me towards resources demonstrating how it could be done, or possibly offer some insight to get me started?

Thanks friends.
