Abstract
A system, method and device for real-time compositing of encrypted video streams without having to decrypt each video stream is disclosed herein. A shared encryption key is derived to encrypt multiple incoming video streams to an encrypted master video stream, while retaining full interoperability with popular incumbent video encryption standards. Compositing video is then possible without having to decrypt the master video stream, thereby preserving the security of the copyrighted material. The invention preferably genlocks a digital video source to a master video stream.
