Harmonic broadcasting was introduced by Juhn and Tseng in 1997 as a way to reduce the bandwidth requirements required for video‐on‐demand broadcasting. In this article, we note that harmonic broadcasting is actually a special case of the priority encoded transmission scheme introduced by Albanese et al. in 1996, and prove—using an information theoretic argument—that it is impossible to achieve the design goals of harmonic broadcasting using a shorter encoding. © 2006 Wiley Periodicals, Inc.
