Straightforward, one-way delivery of video programming through televis
ion sets has existed for many decades. In the 1980s, new services like
Pay-Per-View and Video-on-Demand were touted as the ''killer applicat
ion'' for next-generation Internet and TV services. However, the hype
has quickly died away leaving only hard technical problems and costly
systems. As an alternative, and what we propose, is a new paradigm off
ering flexibility in how programs are requested and scheduled for play
out, ranging from complete viewer control (true VoD), to complete serv
ice provider control (traditional broadcast or cable TV). In this pape
r, we describe our proposed jukebox paradigm and relate it to other on
-demand paradigms. Our new paradigm presents some challenges of its ow
n, including how to best schedule viewer requests, how to provide VCR-
style interactive functions, and how to track viewer usage patterns. I
n addition to addressing these issues we also present our implementati
on of a jukebox-based service called the Interactive Multimedia Jukebo
x (IMJ). The IMJ provides scheduling via the World Wide Web (WWW) and
content delivery via the Multicast Backbone (MBone). We discuss the ch
allenges of building a functioning system and our ongoing efforts to i
mprove the jukebox paradigm. (C) 1998 Published by Elsevier Science B.
