IDTV broadcast applications for a handheld device

Interactive digital television (IDTV) promises to enhance traditional television programming. Current approaches to IDTV generally use either the primary television display or add a second display that resides on a traditional personal computer. This paper outlines a new approach to IDTV that uses a handheld IDTV device, and describes a working prototype that demonstrates the merit of this type of solution. The approach we describe allows interactive content to be delivered to an individual without impacting other viewers. Further, by targeting small devices, IDTV content can become portable, for "anytime, anywhere" interaction.
