Abstract
Video watermarking technique embeds some information into videos by modifying video content slightly. The embedded information, named watermark, may be ownership information, customer information, integrity information, redundancy information, and so forth. Thus, this technique can be used for copyright protection, piracy tracing, content authentication, advertisement surveillance, error resilience, and so forth. In this chapter, we give an overview on video watermarking technology, including its architecture, performance requirement, typical algorithms, hot topics, and open issues.
