Abstract A true video-on-demand system allows users to view any video program, at any time, and perform any VCR functions, but its per-user video delivery cost is too expensive to have commercial use. Periodic broadcasting (PB), which is a near video-on-demand technique, broadcasts videos repeatedly over broadcast channels. In this way, PB can service an unlimited number of clients simultaneously with a bounded service latency. We propose a data retrieval scheme, consisting of buffer management and data placement, for PB servers. Unlike existing schemes devised for a specific PB technique, our scheme can be adopted by general PB. Furthermore, it is devised considering variations in disk load induced by VBR-encoded videos.
