- Nowadays, as the broadcast media are increased and the convergence of broadcast and communications is advanced, users become consumed abundant contents by various devices, at anytime, in anywhere. Moreover, the desire for searching and consuming user-preferred contents is increased. For reasons mentioned above, TV-Anytime metadata standard has been defined, which is the one for supporting an anytime TV program service. In this paper, TV-Anytime standard based service system is proposed, which provides two personalized content services reflecting the user's preference and terminal environment. One is a media library service and the other is a target advertisement service. Media library service is one for transmitting contents selected by user from consumable contents list provided by bi-directional metadata server. For content transmission, two methods - file download and streaming are supported and for a personalized service, it is provided that an adapted streaming service based on multimedia modality conversion technique according to a terminal type such as Set-Top Box and PDA and a usage environment such as network condition. Target advertisement service is one of main broadcast services for end-users, broadcasting stations and advertisers. In bidirectional metadata server, a user profile such as gender and age is reasoned from TV usage history based on TV-Anytime standard and Multistage Classifier algorithm. By this result, targeted advertisement contents are transmitted to end-user. For an implementation of the above services, firstly main components are developed such as TV-Anytime standard based metadata transmission interface module, metadata database, FTP server, transmoding server for multimedia modality conversion and user profile reasoning module and then by integrating these components, the system which is made of bi-directional metadata server, Set-Top Box middleware and PDA application is developed. Lastly, implemented results are presented. ©2006 IEEE.
