STMicroelectronics selects Cinea Running Marks watermarking technology

Semiconductor manufacturer STMicroelectronics has integrated Dolby Labs subsidiary Cinea’s Running Marks watermarking solution into its STi7109 System-on-Chip (SoC) HDTV decoder platform.

The integrated solution is available to all set-top box vendors, conditional access vendors and cable, telco and satellite system operators.

The Running Marks replacement-based architecture offers extensive flexibility to mark compressed content anywhere during the content distribution path and on delivery to a home media gateway. With Running Marks’ ultra-lite message inserter, very few of the SoC computer resources are used. Additionally, system renewability on the backend, with no need for field upgrades, results in a cost savings.

Forensic watermarking, also known as serialization watermarking, enables a unique, session-specific ID or serial number to be placed in every video stream sent from a system operator into a home. By watermarking individual streams, the natural flow of distributed content remains untouched and uninterrupted, yet any source of illegally redistributed content can be traced back to the source.
