Design and implementation of a real-time multimedia presentation system using RTP

Abstract

A new class of protocols like RTP, RTSP and RSVP are tailoring today's packet networks for streaming real time multimedia data that once carried only non real time traffic. Multimedia networking is now possible with the existing network infrastructure. We describe a real time multimedia presentation system for media on demand over the Internet. It uses RTP and is capable of real time video/audio transmission. Our system consists of servers that maintain video/audio clips and clients that retrieve and present them to the users. It provides VCR like control features for user interactivity during playback. The paper describes the system architecture, and the communication protocols, along with media synchronization and dynamic QoS control mechanisms.
