Abstract: The adaptive batching technique is shown to have better performance than the static scheme in terms of total bandwidth requirement and customer reneging probability in multicast video-on-demand (VoD) systems. In this paper, we first analyze the performance of providing VCR functions in the multicast VoD system using adaptive batching. The result shows that the system may not take any advantage from the adaptive approach if VCR operations are incorporated. In view of this, we then explore the buffer reservation and VCR resume delay to further improve the adaptive system. The trade-off among the buffer size, resume delay, and stream requirement is extensively investigated. It is found that a 30-s resume delay or 20% buffer reservation can significantly reduce the batching stream requirement in the adaptive multicast VoD system.
