Abstract

In this paper, we investigate the architectural suitability of Cable TV networks for supporting Interactive Video on Demand. We present the existing cable TV structure and comment on the expected future architecture towards which cable TV networks are rapidly evolving. Practical realization of Interactive Video on Demand is in jeopardy because of an unmanageable peak in the subscribers' viewship pattern. We propose that multimedia servers of suitable capacities be installed at strategic locations in the cable TV network and function as temporary caches for multimedia information delivered from metropolitan repositories. We develop techniques for information caching that take into account the network bandwidth and storage constraints, and transform unmanageable peaks in viewers' demand patter to manageable plateaus.
