QoS - Aware Digital Video Retrieval Application

Abstract

Delivering high quality video content to customers is now expected to be one of the driving forces for the evolution of the Internet as it can be deployed in many niches of the emerging e-market. This chapter presents an originally developed Video Retrieval application with its unique features including a flexible user interface based on HTTP browser for content querying and browsing, support for both unicast and multicast addressing and a user-oriented control of QoS of video streaming in Integrated Services IP networks. The remaining part of the chapter is devoted to some selected methods of information systems’ modelling requested for the prediction of a system performance and an influence of different control mechanisms on quality of service perceived by end users.
