Abstract

With the popularity of video broadcasting service on Internet, many significant broadcasting schemes were proposed to reduce the clients' waiting time. These schemes mostly require clients to receive video segments altogether from all channels. As a result, clients with limited bandwidth, such as XDSL, cannot enjoy video-broadcasting services. To overcome this problem, this work proposes the adjustable interleaving staircase-harmonic broadcasting scheme (AISHB), which offers a tradeoff between any two of three resources: server bandwidth, client buffer spaces, and client bandwidth. When client bandwidth is not limited, the scheme requires a client to buffer only 25% of a playing video and the waiting time is slightly higher than the optimal waiting time. In comparison with the fast broadcasting, recursive frequency-splitting, and harmonic broadcasting, AISHB saves the buffer requirements by 50%, 33%, and 33%. If client bandwidth is restricted, AISHB achieves the smallest waiting time among all currently known broadcasting schemes.
