- Research into high quality media streaming is regarded as an important area of information technology with the rapid development of network technology and digital A/V home appliances. However, a scheme that can flexibly deal with extreme network dynamics is required to realize high quality media streaming service because the modern internet is designed for best effort services. In this paper, we design and implement a scheme that controls quality of service (QoS) based on whether the network can accommodate the required bandwidth of the media. The relative one-way delay (ROWD) trend is used to determine whether the required bandwidth is available and the temporal coding of scalable video coding (SVC), which can be easily applied to real-time systems, is introduced to control QoS. Experimental results conducted with a fiber-to-the-home (FTTH) network show that the proposed system appropriately adapted to variations in network bandwidth and the service quality improved. © 2006 IEEE.
