Data hiding or digital watermarking can be considered nowadays as the most important issue for digital multimedia. The data hiding technique can be used for covert communication, while digital watermarking can be used for protecting digital media content. Many techniques were developed for embedding data into various multimedia mediums. In this paper, we proposed a method for embedding digital watermark into uncompressed videos. It uses the relationship among the DC components in several successive frames for hiding data. Since DC components will not vary a lot after a DCT-based lossy compression algorithm, this approach is able to resist such compression algorithms. And experimental results demonstrate that this proposed method is robust to MPEG coding.
