Commercial markets employ digital right manageme (DRM) systems to protect valuable high-definition (HD) quality videos DRM system uses watermarking to provide copyright protection and own ership authentication of multimedia contents.We propose a real-time vide watermarking scheme for HD video in the uncompressed domain.Espe cially, our approach is in aspect of practical perspectives to satisfy percep tual quality, real-time processing, and robustness requirements.We sim plify and optimize human visual system mask for real-time performan and also apply dithering technique for invisibility.Extensive experimen are performed to prove that the proposed scheme satisfies the invisibilit real-time processing, and robustness requirements against video proces ing attacks.We concentrate upon video processing attacks that commonl occur in HD quality videos to display on portable devices.These attacks in clude not only scaling and low bit-rate encoding, but also malicious attack such as format conversion and frame rate change.
