Abstract

One of the most exciting technologies in today's Internet is the MBone. MBone stands for Multicast Backbone; it provides the infrastructure for efficient multipoint packet delivery in the Internet. The most popular scenario is worldwide audio-video conferencing. However, there are no satisfactory methods of archiving multimedia data streams of multicast videoconferences, nor of making them accessible to remote sites (i.e. how to remotely record and remotely play back MBone conferences). In this paper we present the architecture and a prototypical implementation of the MBone Video Conference Recording on Demand (MVoD) service. MVoD is a client-server based architecture for interactive remote recording and playback of MBone sessions. MVoD is implemented based on open standards (e.g. Common Object Request Broker Architecture and Specification (CORBA)), which allows other applications to interface it. Since the MVoD client application is implemented in JAVA, it is possible to access the service from almost any platform.
