The Video On Demand (VOD) for QuickTime system is made up of a Filmkey Encoder application and a free Filmkey Player that the user can install on Macintosh and Windows computers.
Film files are encrypted video files using a QuickTime container. When the client rents a film, the IP is indeed recorded and transmitted from the Filmkey server to the producer, so that the producer can track errors and misuse of the licenses. Each time the client opens a film file, an internet connection is needed to get the decryption key. The key is not stored in the computer.
