广播协议通过将客户端共享的视频分割成段，有效地传输客户端同时共享的视频。许多研究都集中在减少客户端等待时间上，如固定延迟宝塔广播（FDPB）和谐波广播。但是，pda和机顶盒（stb）等功能有限的客户端设备在观看视频时要存储很大一部分内容。因此，如何减少客户端的缓冲需求是一个重要的问题。相关工作包括楼梯广播（SB）、反向快速广播（RFB）和混合广播（HyB）方案。这项工作改进了FDPB，以节省客户机缓冲空间和等待时间。与SB、RFB和HyB相比，在相同的缓冲需求下，改进的FDPB方案可以产生最小的等待时间。
Broadcasting Protocols can efficiently transmit videos that simultaneously shared by clients with partitioning the videos into segments. Many studies focus on decreasing clients' waiting time, such as the fixed-delay pagoda broadcasting (FDPB) and the harmonic broadcasting schemes. However, limited-capability client devices such as PDAs and set-top boxes (STBs) suffer from storing a significant fraction of each video while it is being watched. How to reduce clients' buffer demands is thus an important issue. Related works include the staircase broadcasting (SB), the reverse fast broadcasting (RFB), and the hybrid broadcasting (HyB) schemes. This work improves FDPB to save client buffering space as well as waiting time. In comparison with SB, RFB, and HyB, the improved FDPB scheme can yield the smallest waiting time under the same buffer requirements.
