“…Base is the scheme only using RTL striping [6] and PAG-1 is the scheme executing only Phase 1 of GPAG. Figure 3 shows disk bandwidth requirement for deterministic QoS, i.e., worst-case disk load, of Base, PAG-1, and GPAG while varying service latency under Skyscraper PB.…”

Periodic broadcast(PB), one of the Near-VOD techniques, can service an unlimited number of clients simultaneously with bounded service latency. Most work on PB has only focused on network bandwidth and client buffer requirements. However, disk bandwidth needs to be considered in order to minimize the server's cost. In this paper, we propose a generalized data placement scheme for PB servers. Unlike existing schemes devised for a specific P-B technique, our scheme does not depend on the PB techniques, and it is devised considering the variation in disk load induced by VBR-encoded videos.

“…It is reasonable to assume round-level disk I/O for our PB server model. And, in round-level disk I/O, it is natural to employ RTL(Round Time Length) striping [6], where the video is divided into one-round data and the data is contiguously stored on disks. The one-round data contiguously stored are called media blocks.…”
