This paper examines the issue of how to build a cost effective system for delivering video-on-demand. Rather than simply utilizing buffer space to minimize aggregate bandwidth requirement from the server as is the common case in many previous works, we examine how to minimize the overall cost when amortized buffer cost and bandwidth cost are taken into account. An algorithm which minimizes this overall cost is presented along with simulation results comparing it with other schemes.
