Abstract

Video on Demand is one of the key application in the information era. An hinge factor to its wide booming is the huge bandwidth required to transmit digitized video to a large group of clients with widely varying requirements. This paper addresses issues due to heterogeneous clients by proposing a program caching scheme called Partial Video Sequence (PVS) Caching Scheme. PVS Caching Scheme decomposes video sequences into a number of parts by using a scalable video compression algorithm. Video parts are selected to be cached in local video servers based on the amount of bandwidth it would be demanded from the distribution network and central video server if it is only kept in central video server. In this paper, we also show that PVS Caching Scheme is suitable for handling vastly varying client requirements
