The build-out of residential interactive networks presents application developers and content providers with new and exciting distribution channels. With this opportunity comes the challenge of delivering compelling multimedia services within a severely resource-constrained environment. Initially, these networks will provide unidirectional broadband data streaming capabilities with limited bi-directional control channels. For economical reasons, the associated customer premise equipment will consist of simple set-top boxes (STBs) containing only a few megabytes of memory and no secondary storage. Given these constraints, the challenge for application developers is to construct a service delivery framework capable of efficiently utilizing powerful upstream computing resources while minimizing latencies due to the interventing network. A client/server software architecture, originally developed for enterprise networks, is the basis of this framework. Combined with distributed computing concepts, a properly partitioned system can provide a very capable interactive network platform. This discussion focuses on the client side of such a system. It explores the usage of interpretive runtime environments for STBs and suggests methods for expanding client functionality through object aggregation and encapsulation.
