Combining Medialive m2mark and Nagravision’s (News - Alert) Conditional Access System, Medialive, a digital content protection company, and Nagravision reportedly have developed a new solution.

Both companies say their Pay-TV and digital content security systems will now have a promising future with the technical collaboration.

This unique combination of content protection and content identification brings service providers additional technical means to dissuade new forms of digital Pay-TV piracy, improving the user experience, controlling content distribution, and being interoperable with leading CAS and tracking systems, as well as emerging copy protection solutions, such as Nagravision’s Persistent Rights Management.

This experimental pay-TV service protection architecture, which explores future paradigms for content protection and distribution, will be demonstrated by Medialive and Nagravision at IBC 2008 on Nagravision booth 1D69. The new m2mark system1 adds watermarks while the content is still scrambled, so that clear content always contains the watermark. Allowing the usage of only a small part of audio/video bit stream in a light watermarking and decryption process in a secure device, the demonstration shows an original scrambling usage.

For improved security from source to end-user devices, decryption and individual watermarking are simultaneously done in the secure device. Both the companies say the new prototype showcases how technologies could improve the traditional scrambling and CA (News - Alert) architecture. These are used in digital satellite and cable TV deployments.

“The new m2mark-based solution allows smoothly bridging content protection technologies with content tracking technologies, while keeping intact the robustness of each independent solution, thus enabling a smart handover from protection to tracking” said Didier Lesteven, chief executive officer of Medialive.” Moreover, it represents a key enabler of market trends: Web VOD, IPTV (News - Alert) media emergence, HD content demand increase and new advertising models.”
