At present, the main means of the broadcast cover in our country are Modulation(MW) broadcast, cablecasting and satellite broadcast. In fact, satellite broadcast is not really satellite live broadcast but a way to transmit the broadcast program using satellite. Then how about using satellite to direct broadcast? In my opinion: the cover area is the most important in the development of the broadcast. It's necessary to using satellite direct broadcast technology to expand the cover area of broadcast, and furthermore, its doable in practical use with the development of the synchronization broadcast satellite technology and digital audio technology.
