Abstract
Technologies based on cable modems currently use the capacity of a single TV channel to offer 25–30 Mb/s downstream for Internet access. With the advent of Digital TV and the significant bandwidth savings it gleans from video compression, it is expected that providers will increase the access capacity available for IP traffic, while retaining the bulk of the bandwidth for the primary service of broadcast TV. Motivated by the increasing popularity of on-demand streaming media, our work questions this IP-versus-broadcast distinction, and proposes a hybrid model which combines the familiar broadcast model with the conveniences of on-demand TV viewing over IP. In this paper we discuss the potential benefits of this approach, and some of the difficult technical challenges it raises. We propose an architecture of network-based portals and sketch the types of services we envisage it will enable. Further, we describe the design and implementation of a replay service that operates within this architecture to offer a new on-demand TV-viewing experience.
