Broadcasting Protocols can efficiently transmit videos that simultaneously shared by clients with partitioning the videos into\r\nsegments. Many studies focus on decreasing clients� waiting time, such as the fixed-delay pagoda broadcasting (FDPB) and the\r\nharmonic broadcasting schemes. However, limited-capability client devices such as PDAs and set-top boxes (STBs) suffer from\r\nstoring a significant fraction of each video while it is being watched. How to reduce clients� buffer demands is thus an important\r\nissue. Related works include the staircase broadcasting (SB), the reverse fast broadcasting (RFB), and the hybrid broadcasting\r\n(HyB) schemes. This work improves FDPB to save client buffering space as well as waiting time. In comparison with SB, RFB, and\r\nHyB, the improved FDPB scheme can yield the smallest waiting time under the same buffer requirements.
