Application level rate adaptive motion-JPEG transmission for medical collaboration systems

In a bandwidth-restricted environment, optimum video delivery is a demanding but a technically challenging issue. Exploiting the trade-off between the image-quality and the frame-rate in adapting to varying channel bandwidth is an attractive solution. We describe an application level adaptive methodology for M-JPEG transmission considering available channel bandwidth and end-host performance. The authors have practically implemented this control methodology in a multimedia collaboration system for medical applications.
