Congestion-aware scalable video streaming

Real-time media applications often ignore ongoing congestion if there is no option to reduce the rate. These applications pose a threat to themselves and other traffic. Reducing the transmission rate requires reducing the amount of packets rather than spreading the transmission over a longer interval. Loss-based congestion control mechanisms are unsuitable for this requirement. Also this rate reduction with popular video codecs, e.g. MPEG4, is often problematic. This paper investigates the problems associated with real-time video transmission over the Internet. We investigate a rate control method minimizing delay and losses and report preliminary but promising results.
