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

The broadcast method is an efficient approach to deliver a hot video for utilizing bandwidth. By combining the Fibonacci and interleaving staircase methods, this paper presents a new hybrid broadcasting method, called FIS method, to deliver a CBR-encoded video. The FIS method provides that users only use a bandwidth of double of the consumption rate to download and watch a CBR-encoded video without break. The buffer requirement of the proposed method is near 20% of the size of whole video. Compared with the Fibonacci and FS methods, the FIS method reduces the buffer requirement by about 50% and 27%, respectively, while maintains very close maximum wait time.
