广播协议可以通过使用少得多的带宽来传输由许多观众同时观看的视频来降低视频点播服务的成本。不幸的是，最有效的广播协议也是最难实现的，因为它们为每个视频分配了大量非常低带宽的流。我们提出了一个协议，每个视频使用三到七个高带宽流，并且比任何其他协议都不需要超过5%的带宽来保证给定的平均等待时间。
Broadcasting protocols can reduce the cost of video-on-demand services by using much less bandwidth to transmit videos that are simultaneously watched by many viewers. Unfortunately, the most efficient broadcasting protocols are also the most difficult to implement because they allocate a multitude of very low bandwidth streams to each video. We present a protocol that uses between three and seven high-bandwidth streams per video and never requires more than five percent more bandwidth than any other protocol to guarantee a given average waiting time.
