NexGuard Pay-TV enables SK Broadband to protect their premium content investment by identifying content leaks and tracing them back to the set-top box of origin

Cheseaux-sur-Lausanne, Switzerland, and Phoenix (AZ), USA – January 12, 2020 – NAGRA, a Kudelski Group (SIX:KUD.S) company and the world’s leading independent provider of content protection and multiscreen television solutions, today announced that SK Broadband, one of the largest broadband Internet access providers in South Korea, has selected NAGRA’s NexGuard forensic watermarking technology to protect the operator’s premium content on a wide range of IPTV set-top boxes.

The NexGuard Pay-TV solution protects premium content investments and, in the event of a breach, will enable the operator to trace any illicit recording or sharing of content from its BTV service and identify the set-top box from which it originated.  

“We selected NAGRA’s forensic watermarking solution for set-top boxes because it enables us to meet content owner requirements for the protection of premium content, including 4K, and insert an invisible watermark without affecting video quality,” said SangBum Lee, VP of SK Broadband. “What’s more, NAGRA’s local presence along with their proximity to the studios through their Los Angeles-based teams, were all strong considerations in our selection.”

NexGuard forensic watermarking is the most-widely deployed forensic watermarking solution in the region. NexGuard Pay-TV is designed to protect premium pay-TV services delivered via a set-top box, including 4K Ultra HD, premium VOD, and live sports content. It embeds a subscriber-specific forensic watermark in a managed pay-TV client device (set-top box or smart TV). The integration for SK Broadband is part of the SK Broadband app for Android TV and is supported by all the major chipset vendors, requiring no additional video processing on the head-end side. 

“With the increased availability of premium 4K content also comes increased risk for piracy and content leaks which tempers content owners’ willingness to deliver premium content into the market,” said Stéphane Le Dréau, SVP Sales APAC, at NAGRA. “NAGRA’s NexGuard forensic watermarking solution is a leading product in the fight against piracy and we welcome SK Broadband into this active anti-piracy community.”

The NexGuard range of forensic watermarking solutions is a key component of NAGRA’s active streaming protection framework which is designed to equip service providers with a comprehensive security toolset to secure their IP video investments.
