Building on recent advances in digital rights management, digital video broadcast networks, and interactive TV, we present a system that lies at the intersection of these evolving technologies. The system presented in this paper combines the powers of these technologies, in a novel way, and represents a new generation of scalable, far-reaching, secure e-commerce systems for trade in copyright protected content. The introduced system enables users, tuning to a digital TV channel, to be presented with entertainment material that promotes digital content available for download
over the same broadcast channel (e.g., a music video that promotes an audio album available for download). Users, interacting with an application running on the set-top box, can either select and download the promoted content to a secured end-user device, or browse a catalog of all digital content offered for download. The MPEG-2 standard transport stream for broadcast transmission is a natural candidate for the communication channels used in the system, as it allows the solution to be deployed over virtually all types of digital broadcast networks.
