Abstract
Video data hiding presents a required to hide data in the transformed domain. Compared with still images, video watermarking presents a much higher capacity or bandwidth. At the same time the computational complexity in video watermarking is higher due to the amount of data that need to be processed. Since a video is formed from a sequence of frames, it presents the data hider with the possibility to embed and send a large amount of data[1].
Data hiding in video sequences is performed in two ways, bit stream level and data level. In the bit stream level the redundancies in the current compression standards are exploited.
