NAB 2026: Synamedia Launches Edge Watermarking Solution, Marks 10 Years of ContentArmor

Synamedia has announced ContentArmor Edge Watermarking, a server-side solution that inserts watermarks at the CDN edge to enable faster detection and removal of pirated video streams. The solution is CDN-agnostic, with the first integration available now via Synamedia Fluid EdgeCDN. It will debut at NAB 2026, ten years after ContentArmor was founded.

ContentArmor Edge Watermarking embeds unique watermarks directly into the compressed stream at the CDN edge, reducing end-to-end session disruption time to below five minutes - cutting insertion and extraction times in half compared to existing methods. For VOD content, the solution eliminates the need for two streams, reducing bandwidth between origin and edge servers and lowering infrastructure requirements.

The industry has historically relied on A/B watermarking, where two versions of encrypted content are cached in the CDN and a scrambled sequence of segments is served to each user. Edge watermarking was not previously feasible due to limited CPU capacity at the edge and the absence of DRM encryption keys on edge servers.

The new solution encodes content once at the headend, distributes it through the CDN, and then inserts a unique session identifier at the edge via a lightweight watermarking agent. The watermark achieves faster extraction than A/B watermarking through higher bit density.

This product is the result of a ten-year journey to make server-side forensic watermarking possible at the edge, says Alain Durand, Senior Director at Synamedia. Since ContentArmor was founded in 2016, we understood the potential of edge watermarking, but it wasn't technically feasible or scalable until now. As the only provider offering server-side watermarking in the compressed bitstream, together with Synamedia's CDN expertise, we have overcome technical challenges, integrated watermarking directly with the CDN for the first time, and achieved the scalability needed to support live streaming.
