In this paper, we address the bandwidth reservation issue when MPEG-2 encoded VBR video streams are transmitted over wireless access networks using hybrid ARQ schemes to combat channel errors in VoD services. In addition to the original bandwidth which is necessary for the VBR traffic, a certain amount of excess bandwidth has to be reserved for retransmissions required by hybrid ARQ schemes. Different excess bandwidth reservation algorithms are proposed and investigated via simulations. The performance results are then presented and compared
