Abstract
While the broadband network and multimedia technologies have been developing, the commercial market of digital contents also has been widely spreading with recently starting IPTV. As the IPTV services are getting to be generalized and popularized, the contents illicit copying and distribution of copyright meterials tends to draw more attentions. So we need a right service system that can protect contents and copyright using watermark inserting. Until now, the conventional protection and authentication system is taking advantages of merits both in CAS and DRM. But this system can not protect the contents when acquiring them from TV output using A/D convertor. So we apply watermark method using HSI color space against contents illicit copying. And for distribution of copyright materials. we compound unique settop ID and copyrighter's ID to make new ID that is watermark. When inserting watermark, we use the watermark for copyright protection and authentication. So we can protect copyright and identify last settop's user in illicit distribution. we design download based IPTV contents protection and authentication system using HSI watermark method.
