An architecture for viewer-side enrichment of TV content

This paper presents a user interface model and implementation for exploiting next-generation interactive capabilities with the domain of television content. Our work studies capabilities that extend a user's potential impact over the consumption and sharing of television programs. The main capabilities of our environment include personalized viewing and navigation within a program fragment, and the ability to actively personalize content via various end-user content enrichments (such as line art, referrals and hyperlink insertions). In this paper, we present the implementation of a range of "couch-top" control and editing devices, including personal devices such as personal digital assistants and ad-hoc interactive devices. This paper also presents an architecture that decouples user actions into activators and handlers. We provide an overview of the interaction architecture and report on a series of deployment experiments on a wide range of consumer electronics devices.
