Extending critical bandwidth allocation techniques for stored video delivery across best‐effort networks
Wu‐chi Feng, Ming Liu · International Journal of Communication Systems · 2001
Abstract In this paper, we propose two new techniques for the delivery of compressed prerecorded video streams across best‐effort networks like the Internet. Current approaches for the delivery of stored video across best‐effort networks typically alter the quality of the video frames, the frame rate delivered to the user, or a combination of both. By using network feedback, these algorithms continually adjust the video quality to fit within the available network resources. These approaches, however, do not take advantage of thea prioriinformation available from stored video streams, namely the frame sizes that the movie consists of. We will show how monitoring thea prioriinformation and actively monitoring a client‐side buffer can helpsmooththe video frame rate delivered to the user, providing a more consistent quality of video.
