Digital broadcast technology and the growth of the internet have facilitated the distribution of high quality digital video content to consumers. However, this has also led to an increase in video piracy and the associated loss of revenue from media sales. Digital watermarking is a potential solution to the protection of video content from piracy.
The term digital watermarking is used to refer to the addition of information to media content in such a way that it is imperceptible to media users, but can be retrieved from the media using some method of computer processing. This embedded information may be used to pass on copy-protection information to playback and recording devices or to trace the source of illegally made copies. Watermarking specifically involves embedding the added information in the physical, analogue information of the media, as opposed to appending the extra information separately to its digital data representation. The former approach is considered more robust, since the latter technique can easily be circumvented by simply removing the added information. Watermarking may be applied to different forms of media, including audio, images and video. For this project we will attempt to apply communication techniques to digital video watermarking.My contact details: firstname.lastname@example.org
