"This article is focused on the watermarking issue and especially on the techniques of inserting watermarks to the digital video. After theoretical background of watermarking techniques, one method for watermarking digital video in frequency domain was chosen. This technique is based on the Discrete Cosine Transformation and reason of this choice is a good robustness against the transformation and loss compression watermarked video. For this watermarking method a theoretical description of software solving is made. The resulting application is based on application programming interface Java Media Framework, which enables audio, video and other time-based media to be added to applications and applets built on Java technology. This program provides inserting and detecting a watermark in the video file. In conclusion, the description of the application is carried out."@en . . .
