A video system includes a first video device. The first video device includes a video output port and an arbitrary data scrambler. The first video device transmits a video stream through the video output port. The video output port is configured to insert video timing reference values into the video stream. The arbitrary data scrambler is configured to scramble non-video data for transmission in the video stream such that unscrambled non-video data containing video timing reference values is transformed, without information loss, to scrambled non-video data containing no video timing reference values.
