Abstract
A streaming video server stores playlist data corresponding to a plurality of video programs available from at least one video source. A command handler receives a program request for a selected one of the plurality of video programs from the at least one client device via the network interface and further receives a custom key request via a custom URI handler of the client device to access at least one encryption key. In response to the custom key request, the command handler sends secure key data to the client device in accordance with a custom key exchange protocol.
