While generally the watermarking methods are designed to protect high quality video (e.g. DVD), a continuously increasing demand for protecting very low bitrate video (VLBV) – e.g. in mobile networks, the video stream may be coded at 64kbit/s – is also met nowadays. In this respect, a special attention should be paid to the statistical behaviour of the video content. At our best knowledge, this paper presents the first statistical investigation on VLBV in the DCT (2D Discrete Cosine Transform) domain, thus identifying the particular way in which the VLBV obeys to the very popular Gaussian law. It also points to critical behaviour differences between the high and very low bitrate videos. These theoretical results are validated under the framework of watermarking experiments carried out in collaboration with the SFR mobile service provider (Vodafone group).
