Broadcasting real-time and stored for replay sound, video and multimedia material to small handheld devices such as cell phones is the ‘Holy Grail’ of both the telecommunications and broadcasting industries. We discuss the needs of such systems and the major approaches to achieving it: Eureka 147 T-DMB, DVB-H, ISDB-Tsb, Qualcomm’s promising MediaFLO and the broadcasting function of Mobile WiMAX. We also discuss the Japanese and South Korean MBSAT T-DMB broadcast system.
