PSEUDO HARMONIC STAGGERED BROADCASTING METHOD FOR EFFICIENT VIDEO ON DEMAND SERVICE
Advances in broadcasting technology are generating an increasing demand for Video on Demand (VoD) applications. In a video broadcasting methods, one of the major challenges is how to reduce a viewers waiting time and clients buffer requirement in a given bandwidth allocation. In order to solve these problems, many significant broadcasting methods had been proposed. In this paper, we propose a Pseudo Harmonic Staggered Broadcasting (PHSB) method which has simple structure and channel efficiency in a given bandwidth. The numerical results demonstrate that viewers waiting time of the PHSB method converge to that of harmonic method as the bandwidth is increased and the client buffer requirements of this can be decreased below that of the staircase method by adjusting a short front part of a video size.
