Description
Summary:Digital video stream transferring via the network has become very popular in recent years. However, this frequent use of the Internet may increase the requirement for copyright and security. As a consequence, to prevent video stream which belongs to rightful owners from being intentionally or unknowingly used by others, information protection is indispensable. Digital watermarks have been embedded invisibly into digital video to protect copy rights of legal owners. An effective watermarking procedure usually requires satisfaction of a set of typical requirements such as transparency, robustness, oblivious detection and so on.
