Abstract

We present a new video broadcasting protocol called the scalable preloading broadcast protocol. This protocol provides cost effective access times to viewers by using a scalable preloading method. The new protocol reduces the video stream management complexity as well as the required broadcasting bandwidth. To demonstrate the benefit of new protocol, we perform various simulations to compare its performance with that of previous broadcasting protocols. With simulation results, we show that our protocol's required bandwidth is very close to the theoretical minimum throughout all client waiting times. Furthermore, by comparison with previous broadcasting protocols, we also show how our broadcasting protocol can dramatically reduce the video stream decoding complexity.
