Abstract
The present invention relates to a method and system for implementing a large area and continuous coverage of programs in a digital audio broadcasting, wherein, part of carrier frequencies are set as common carrier frequencies, and other carrier frequencies are set as service carrier frequencies; all of the common carrier frequencies are combined together to achieve a seamless coverage for the large area; a transmitting end transmits a common frequency point identifier and a program information list on the common carrier frequencies, and transmits digital broadcasting programs on the service carrier frequencies; a receiving end identifies the common carrier frequency based on the common frequency point identifier and receives the digital broadcasting program on the common carrier frequencies; for a specific program desired to be received, all the carrier frequencies on broadcasting of the program are searched based on the received program information list, and the carrier frequency with best signal quality is selected for receiving; during the reception process of the specific program, signal quality of other carrier frequency on broadcasting of the specific program is monitored, and when the signal quality of current receiving carrier frequency decreases, the program is continue to be received by switching to another carrier frequency with better signal quality. By using the method and system according to the present invention, it can be realized that programs can be continuously covered for a large area and received seamlessly.
