Abstract [en]

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.
