A Real-time Audio Streaming Method for Time-varying Network Loads

This paper proposes a real-time audio streaming method that dynamically adjusts time-varying network loads. Most current Internet services are best-effort services in that the Quality of Service (QoS) is not guaranteed. The proposed streaming method is based on RTP/RTCP/UDP protocols in order to handle transient changes of network loads. To cope with time-varying conditions in networks, initial network bandwidth and available bandwidth are measured. The Bit-Sliced Arithmetic Coding (BSAC) that provides efficient Fine Grain Scalability (FGS) is used to adapt to network load fluctuation. The results show that our proposed scheme with the BSAC tool allows a real-time continuous play over networks by maximizing QoS of transport data.
