Proceedings, 4th IEEE International Conference on Image Processing, October 1997
Introduction
We propose an architecture which can support video services in networks which have no Quality of Services (QoS) guarantees. We demonstrate that there is a need for such services today and also in the future, when QoS will be built into most networks. We then describe our current Internet-based system, which combines both image processing and networking techniques in order to provide good quality video without harming the performance of the Internet. These techniques are shown to be superior to previous work for the environment of video services operating in the Internet. We also present experimental results gathered in both a controlled environment and in external wide area connections across the Internet.
