An Adaptive Mechanism For Pre-recorded Multimedia Streaming Based On Traffic Conditions

The multimedia streams transmissions, done over the existing "best-effort" networks, are continuously increasing in number, making network congestion more likely to appear. The paper presents a traffic-based adaptive technique for transmitting pre-recorded multimedia streams, regardless the network condition. The adaptive mechanism is implemented by a feedback-controlled multimedia system which ensures continuous transmissions and play-out of streams even in congested network conditions. The measures taken into account vary the quantity of streamed data with the expense of modifying the streams' quality. Experimental results show improved behavior of the system in highly changing network conditions.
