A hybrid staggered broadcasting protocol for popular video service

Abstract

In a popular video broadcasting method, two major technical issues are focused on both to reduce the viewer's waiting time maintaining a given bandwidth allocation and the client's buffer requirements. In this paper, we propose a pagoda staggered broadcasting (PSB) method which has a simple structure and substantially improves broadcasting efficiency in given bandwidth. The proposed method performs significantly better than the existing broadcasting methods in the viewer's waiting time and the buffer requirement with simplicity. The numerical results demonstrate that the viewer's waiting time of the PSB method is nearly equal to the existing pagoda broadcasting methods. However the complexity of this method decreases up to 60% if dividing coefficient h is 1 by adjusting the short front part of a video.
