Enhancements in DVB-H and DVB-SH based mobile-TV multiplexing

Energy efficient broadcasting of mobile-TV content through DVB-H and DVB-SH suffers from signaling limitations introduced by the DVB-H and DVB-SH multiplexing scheme resulting in an increased system delay. This paper presents a novel scheduling and multiplexing approach to overcome these limitations. The proposed algorithm allows to trade time slicing efficiency for lower system delay and more flexible data rate assignments possibly resulting in better video quality. The algorithm is evaluated through extensive cross layer simulations for different parameter sets.
