In order to use DRM in the StreamOne player you must set the DRM information in the playlist. This is set in within the locations->adaptive section. See this playlist JSON for an example. Note that the player in this example wont be able to playback, due to missing working DRM licenses

StreamOne player setup

StreamOnePlayer('video', {
	skin: 'skin/default/streamone.css',
	playlist: playlist
}, function() {
	player = this;
