The minimum bandwidth required at each time slot of the fast broadcasting scheme

a r t i c l e i n f o a b s t r a c t In this paper, we show that the Fast broadcasting scheme (L.-S. Juhn and L.-M. Tseng, 1998 [4]), abbreviated the FBR scheme, is also suitable for heterogeneous clients of different communication capabilities although it is originally designed for homogeneous clients of the same bandwidth. Given α channels of total bandwidth α · b Mbps to deliver a video of the consumption rate b Mbps, we first show that the FBR scheme can be employed to serve clients with communication capabilities ranging from b to α · b Mbps. Furthermore, we propose a simple way to determine the minimum bandwidth required at any given time slot.
