Abstract

This paper introduces an interactive video system and its architecture where several systems cooperate to manage the services of interactive video. Each system is specialized according to the data it handles and the functionality it performs. A system can be a database (for billing purposes) or just a video store system (to store the video data) lacking the typical features of a database or an information retrieval system to support indexing and querying of video data. Because quality of service is an important requirement for whole management system, a specific system is introduced in the architecture. Such system monitors the bandwidth of the network, the buffer size and the frame size and rate. The resulting architecture of interactive video system consists of several systems cooperating through an active rules based workflow system to integrate their functionalities while preserving autonomy, extensibility and data integrity where necessary.
