Novas Técnicas de Compartilhamento de Banda para Servidores de Vídeo sob Demanda com Interatividade

Carlo RodriguesRosa Maria Meri Leão

This work presents two new bandwidth sharing techniques for video on demand servers with interactivity: Efficient Interactive Patching - PIE and Complete Interactive Patching - PIC. We still obtain an approximation for a threshold used for merging and opening data streams in the system, discuss over other related thresholds, and investigate the use of local buffer in the client side. Through simulations and competitive analysis we show for instance that the bandwidth savings are significant and that the approximation proposed for the threshold is adequate in certain scenarios. We are also able to quantify the influence of the local buffer on the bandwidth optimization and on the system complexity.
