广播协议可以通过减少传输由许多观众同时观看的视频所需的带宽来提高视频点播服务的效率。最近已经表明，对于每个视频使用非常大量的非常低带宽流的广播协议比使用由所有视频共享的几个高带宽流的协议需要更少的总带宽。我们提出了一个混合广播协议，结合了这两类协议的优点。我们的宝塔广播协议只使用少量的高带宽流，只需要稍微多一点的带宽比现存的最佳协议，以实现给定的最大等待时间。
Broadcasting protocols can improve the efficiency of video on demand services by reducing the bandwidth required to transmit videos that are simultaneously watched by many viewers. It has been recently shown that broadcasting protocols using a very large number of very low bandwidth streams for each video required less total bandwidth than protocols using a few high-bandwidth streams shared by all videos. We present a hybrid broadcasting protocol that combines the advantages of these two classes of protocols. Our pagoda broadcasting protocol uses only a small number of high-bandwidth streams and requires only slightly more bandwidth than the best extant protocols to achieve a given maximum waiting time.
