Abstract-- This paper presents implementations of two MPEG-4 Streaming scenarios (remote retrieval and broadcast) for the delivery of multiple elementary stream presentations containing audio-visual objects. These systems have been tested with the MPEG-4 demonstration software implementation (IM1), but are in fact generic platforms for multimedia presentation delivery. The signalling and delivery layer of these system implementations conform to the recommendations made by part 6 of the MPEG-4 standard, Delivery Multimedia Integration Framework (DMIF). We present the issues involved in designing our streaming server for the remote retrieval and broadcast scenarios. The remote retrieval system enables interactive media streaming across the Internet through its Data and Control Planes. The implementations also include a sourcebased rate-control system, a Synchronization Layer packetizer, and a signalling mechanism.
