title = "A distributed MPEG video player system with feedback and QoS control",
abstract = "When a distributed MPEG player system is transmitting MPEG video streams over an open network, like the Internet, the system usually has no control on the network traffic. We define the quality of service (QoS) for video transmissions in an adaptive mechanism, and we propose a priority feedback mechanism with QoS Control (PFB-QoS) for a distributed MPEG player system. With the feedback signal coming from each client and our predefined priority mapping functions, the current status and priority of each client can be obtained. With such information, the video server will adapt to the dynamic changes in the network and make efforts to maintain the QoS requirement for each client under the current network constraints. From our preliminary experiments, we find that when a video server is serving multiple clients where every client can demand a different QoS, the use of a priority feedback mechanism can effectively maintain the committed quality of service.",

note = "Funding Information: Streaming video systems, like RealPlayer and RealSystem G2 from RealNetworks [20], VDOLive Player from VDOnet [21], InterVU Player [23] and Streamworks from Xing Technology [22] are commercially available. However, the performance of such systems highly rely on the available bandwidth, utilize large amount of buffer, and do not provide much QoS guarantees on the video, not to mention that each of these system has its own proprietary video format. On the other hand, there are video servers like the Tiger Video Fileserver [4, 6] that can scale up nicely and provide guaranteed QoS at the expense of a fully controlled high bandwidth network. Hence, there are relatively few video systems that can do full-screen streaming of MPEG video over an uncontrolled network while still providing some guarantee on the QoS of the video being displayed.
