Abstract

Continuous media, namely video and sound, is beginning to conquer computer networks. The possibility of transmitting such media over networks facilitates new kinds of distributed applications such as digital television broadcasting, teleconferencing, multimedia information systems, and group collaboration. All these applications, collectively called multimedia applications, require the transmission of multimedia data streams. The inherent real-time constraints of multimedia data place new demands on network systems and the employed transport protocols. This Project investigates into the general and time-related characteristics of multimedia data streams and multimedia applications. Furthermore, it reviews several techniques, which have been developed recently by the Internet community for the transmission of time critical data. In pa1ticular, the Internet Integrated Services Architecture, the Resource ReSerVation Protocol, and the Real Time Transport Protocol receive special attention. Luckily most of these protocols nre implemented in Java Media Framework (JMF), a va lue able toolkit from Sun Microsystems TM. Distributed multimedia applications require a design that emphasizes flexibility, modularity, expandability, and efficiency. The object oriented paradigm offers proven methods for the design and implementation of complex applications. The choice for implementation is pure object oriented Java Language. JMF being part of Java language provides object oriented implementation of various aspect of multimedia communication
