Data broadcasting is independent of arrivals of requests, and thus it is suitable to transmit popular videos. One broadcasting method, periodic broadcasting, divides a popular video into segments, which are then simultaneously broadcast on different data channels. When clients want to watch the video, they download the segments from these channels. Client-Centric Approach (CCA), greedy disk-conserving broadcasting (GDB), skyscraper broadcasting (SkB), fibonacci broadcasting (FiB) support a client with a small bandwidth. Specially, SkB and FiB support two-channel client bandwidths to receive video segments, and FiB has smaller waiting time than SkB. Extending FiB, this work designs a fibonacci broadcasting plus (FiB+) scheme which has the same waiting time as FiB; however, FiB+ requires small buffering spaces than FiB. The performance evaluation shows that FiB+ has at least 20% smaller client buffer requirements than FiB in most situations.
