True VoD systems provide interactive on-demandvideo service by allocating each client a dedicatedstream. Such a scheme is inefficient when the system hasa large number of users. A more scalable solution is touse a combination of multicast and unicast channels withclient buffering. The present paper shows the design of aVoD proxy server that accepts interactive commands fromthe users using unicast channels and using short unicaststreams to "merge" users onto the existing multicaststreams by using patching and pre-fetching technique.The VoD proxy server is augmented with a dynamicmedia delivery algorithm which, guarantees the mediadelivery without starvation or glitches, reduces the usagetime of unicast channels and reduces the service time ofmedia delivery. Performance results obtained from a realimplementation show the viability of the proposed VoDserver.
