In Harmonic windows scheduling (HWS), a data file is divided into N pages and the pages are scheduled in c channels in such a way that each page i appears at least once in some channel in every window of size i. The optimal HWS problem aims to maximize N. Let κ be the largest integer satisfying Hκ ≤ c, where Hn is the nth harmonic number. Then κ is an upper bound on N, if the HWS framework is used. Thus an optimal HWS schedule wastes “bandwidth” at least c–Hκ. Harmonic block windows scheduling (HBWS) generalizes HWS by grouping b consecutive pages into a superpage. Let N be the total number of pages scheduled. The ratio N/b is directly proportional to the maximum initial waiting time in Media-on-Demand applications. We propose a method that starts with a HWS schedule and modifies it to generate a HBWS schedule that achieves a higher ratio N/b. For up to five channels, we demonstrate that we can always achieve N/b κ. We also prove that as we increase b, N/b approaches the theoretical upper bound.
