The Challenges of Forensic Watermarking UHD/HDR Content
For the past decade forensic watermarking has become an important tool for major content owners to protect their high value content against piracy. Tracking the advances in consumer electronics, content owners are making higher quality content directly available to consumers in the form of video with 4K resolution, Wide Color Gamut (WCG), High Frame Rate (HFR) and High Dynamic Range (HDR). — Watermarking algorithms face new challenges due to the introduction of new formats, better displays and higher quality video. More elaborate visual models are needed to ensure imperceptibility under better reproduction, whereas dramatically increased uncompressed data rates challenge computational efficiency. At the same time, the watermark should survive down conversions in resolution, color gamut, frame rate and dynamic range. This paper describes how 4K, WCG, HFR and HDR formats impact watermarking algorithms and presents approaches to handle these challenges.
