What is it about?

Recently, many people watch movies, TV series and documentaries in his/her PC or mobile devices using the online video service. The proposed system provides auxiliary information about pictures and movies, such as the place, the date, author’s name, the biography of the movie stars and so on, if a viewer desires these additional information.

Why is it important?

The auxiliary information is embedded into the image or video in the imperceptible manner using the watermarking technique, and if a viewer desires to get some additional information, which is revealed by binarization operation. To obtain appropriate functionality for any types of images or frames of video, the proposed system combines visible and invisible watermarking techniques.

Perspectives

Writing this paper is a great pleasure for us. We hope that this paper serves for further development of the stream media, providing viewers a tool to obtain easily some auxiliary information about digital contents.
