Recent advances in storage technology provides an effective way to sto
re video in digital and compressed form. This, coupled with the recent
dramatic increase in the bandwidth of networks, make it possible now
to provide to viewers ''movies on demand'', thereby eliminating the in
flexibility inherent in todays broadcast cable systems. A movie on dem
and (MOD) server is a computer system that stores movies in compressed
digital form and provides support for different portions of compresse
d movie data to be accessed and transmitted concurrently. Such a serve
r not only enables viewers to watch a movie at any time they desire, b
ut also enables them to apply VCR operations like pause, resume, fast-
forward and rewind to the movies they are currently watching. In this
paper, we present a disk-based storage architecture for a MOD server.
We present a clever strategy for striping movies that enables simultan
eous access and transmission of different portions of a movie. We also
present a wide range of schemes for implementing VCR-like functions i
ncluding fast-forward, rewind and pause.
