A Broadcasting Scheme with Low Buffer Requirement for Users with Limited Bandwidth

The broadcast method is the most efficient approach to deliver a popular video for utilizing bandwidth. By combining the Fibonacci and staircase methods, this paper presents a hybrid broadcasting method with low buffer requirement to deliver a constant bitrate compressed video. The proposed method allows users with bandwidth of double of the consumption rate to download and watch the video without break. The buffer requirement of the proposed method is 26.4% of the size of whole video. Compared with the Fibonacci method, the proposed method reduces the buffer requirement by about 30% while provides relatively acceptable wait time.
