Abstract
In this paper we propose a method to watermark digital video content in such a way that detection in consumer electronics equipment is possible with very little hardware (a few thousand gates). The method proposes to modify the MPEG encoding procedure to choose the so-called Picture Type of video-frames not from a regular sequence but according to a message one would like to transmit. Removal of this embedded message, the PTY-Mark, from the resulting MPEG-stream with- out jeopardizing video quality is only possible after a complete MPEG decoding and re-encoding cycle. We investigate the modifications to cur- rent MPEG encoders which are necessary to accommodate these PTY- Marks. Based on tests we comment on their feasibility. Detection of watermarks without secrets is very reminiscent of "public-key" cryptography. We discuss this relationship by contrasting PTY-marks with pixel-watermarking.
