RTP packetization of MPEG-4 elementary streams

Multimedia streaming is becoming increasingly popular. The multimedia standard MPEG-4 was designed to support scenes of different levels of complexity and applications with low bandwidth up to very high bandwidth requirements. Scalable video encoding is supported as well. This allows MPEG-4 streaming software to adapt video quality dynamically in the network to currently given QoS conditions. We evaluate packetization modes designed to transport MPEG-4 elementary streams over RTP connections, based on an implementation of an MPEG-4 video server and a demo client. Suitability of the packetization modes for video stream adaptation in the network nodes is discussed.
