This method of DRM (Copy Protection) has started turning up on BD and other theatrical digital recordings and is currently (starting in 2012) detected by Sony PS3 and maybe some other Blu-Ray players.
It is an additional protection method to AACS and is also designed to protect media that is captured by video cameras, CAM or TS recordings. The detection of the "watermark" in the recording by the playback device will suspend the playback of the media after a period of time. It is supposed to be able to determine whether the copy was made from a camera or a direct copy of the BD, i.e. a "rip".
