A new method of video scene content characteristic detection is proposed. This method

can be applied in conjunction with digital watermarking schemes in order to improve the

transparency. In addition, new methods of video watermarking are also proposed. Three related

original aspects are reported. First, the authors’ previous robust image watermarking methods,

which consider the block texture are extended into video. In the detection process, watermark

extraction with or without the original fr a me is provided. Secondly, a method is proposed to

improve imperceptibility by reducing the flickering effect. Finally, a method is introduced to detect

video scene characteristics in order to suit the particular embedding scheme. By doing so, the

embedding method can be chosen adaptively in accordance with the video scene. The subjective

tests illustrate an imperceptibility improvement and experiments with various attacks show the

watermarking robustness.
