Abstract: Methods and apparatuses for processing and watermarking a transport stream with a message. A processed transport stream that includes processed content packets, associated carrier packets, and a watermark descriptor for a group of the associated carrier packets is created from the transport stream. The processed content data represent a first watermark value and are bounded by transport sector boundaries. The associated carrier packets include replacement watermark data that represent a second watermark value and are bounded by transport sector boundaries. These associated carrier packets are paired with processed content packets. The watermark descriptor includes synchronization data. A watermarked transport stream is created by interleaving selected processed content packets and associated carrier packets according to a watermark message.

Abstract: The present invention is a system for securing broadcasting content locally at receiving stations that may be remote to a broadcaster. Embodiments of this invention implement controllable and renewable security measures, compatible with many other content processing and display systems. These security measures may include re-encrypting received broadcast content using locally generated keys, watermarking the received broadcast content, and logging both processing and display of broadcast content.
