Abstract

With the growth of broadband networks, the video-on-demand (VoD) becomes realistic. Many significant broadcasting schemes are proposed to reduce the bandwidth requirements for stored popular videos, but they cannot be used to support live video broadcast perfectly. Herein, we propose a new broadcasting scheme, called adaptive live broadcasting (ALB) scheme, which supports live video broadcasting and performs well over a wide range of request arrival rates. From our analysis and comparison, we find that our ALB scheme is suitable to broadcast live video. It has several significant advantages: (1) it has the shortest maximum waiting time with fixed channels; (2) it has the least maximum I/O transfer requirements with fixed maximum waiting time at client end. Finally, a simulation is employed to evaluate several live broadcasting schemes, such as UD, ST AFB and ALB. The results reveal our ALB scheme consumes the least server bandwidth.
