Abstract
The invention is a novel watermark in a media sequence and systems and methods for embedding and detecting the watermark. Different watermarks from a watermark set of pseudo random watermarks are selected (randomly or by a selection pattern) and each selected watermark is embedded in a different selected I-frame set of the media stream. Identifying the known sequence of watermarks in the stream of I-frames of a copy can identify the video stream from which the copy originates.
