Question about vanilla HLS protection.

[skewdo]

Hello there,

I want to deploy protected VOD service for iOS on AMS, but for now I can't prepare an AIR application for our service.
So I'm planning to start with vanilla protection.

I know vanilla is only option can be played on iOS Safari/Quicktime without specific application.
I wonder whether customers can play once download streamed movie without server connection.

I can't find how the scheme works in the help document.

I just make sure customers can't play local downloaded contents.

Thank you.
