Watermarks for Mobile Television Fraunhofer-Gesellschaft (10/07)
as it appeared in the October 17, 2007 edition of ACM TechNews.
The Fraunhofer Institute for Secure Information Technology SIT has developed a strong video watermark that will provide protection for mobile television programs that offer interactive content. As part of its porTiVity project, Fraunhofer SIT has created a video watermark that permanently labels TV material without interfering with the processing of video footage and incorporating additional information. Viewers' desire to interact more with TV programs has prompted Fraunhofer SIT to develop a rich media iTV system for mobile television, which would enable them to select objects on the screens of their devices. "During a football match, for example, viewers could click on individual players to view their goal and assist statistics," says Fraunhofer SIT's Patrick Wolf. Broadcasters would also be able to use the optional content to offer viewers interactive prizes or edutainment formats. The porTiVity project also includes an authoring system for tracking moving objects that can be linked to additional, interactive content. Broadcasters would receive rich media content in the form of a special MPEG-4 video that includes the main program and interactive elements. Click Here to View Full Article
