Much research has been made to make it possible the ubiquitous video services over various kinds of user information terminals anytime and anywhere. In this paper, we design a prototype system for the seamless TV program content consumption based on user preference via various kinds of user information terminals in digital home environment, and we show an implementation and testing results with the prototype system. The prototype system operates with the TV Anytime metadata for the consumption of TV program contents based on user preferences in TV program genres, and use the MPEG-21 DIA (Digital Item Adaptation) tools which are the representation schema formats in order to describe the context information for user environments, user terminal characteristics, user characteristics for universal access and consumption of the preferred TV program contents. The proposed content mobility prototype system supports one or more users to seamlessly consume the same TV program contents via various kinds of user terminals. The proposed content mobility prototype system consists of a home server, display TV terminals, and user information terminals. We use 42 TV programs contents in eight different genres from four different TV channels in order to test our proposed prototype system.
