Abstract

Recent advances in computing technology havebrought multimedia information processing to prominence. Theability to digitize, store, retrieve, process, and transport analoginformation in digital form has changed the dimensions ofinformation handling. Several architectural and networkconfigurations have been proposed for efficientand reliable digital videodelivery systems. However, these proposals succeed only inaddressing subsets of the whole problem.In this paper, we discuss the characteristics of videoservices. These include Cable Television, Pay-Per-View,and Video Repository Centers. We alsodiscuss requirements for “Video On Demand” services.With respect to these video services, we analyze two importantvideo properties: image quality and response time.We discuss and present configurations of aDigital Video Delivery System (DVDS) from threegeneral system components - servers, clients, and connectivities.Pertinent issues in developing each component are also analyzed.We also present an architecture of a DVDS that can support thevarious functionalities that exist in the various video services.Lastly, we discuss data allocation strategies which impact performanceof interactive video on demand (IVOD). We present preliminary resultsfrom a study using a limited form of mirroring to supporthigh performance IVOD.
