Abrégé

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.

Abrégé

The present invention relates to a method and a system for implementing large-area continuous coverage of a program in digital audio broadcasting. The method comprises: setting part of carrier frequencies as public carrier frequencies, and setting the other carrier frequencies as service carrier frequencies; combining all the public carrier frequencies together to form seamless coverage of a large area; sending, by a transmission end, a public frequency channel number identifier and a program information list on the public carrier frequencies and sending a digital broadcasting program on the service carrier frequencies; recognizing, by a reception end, the public carrier frequencies according to the public frequency channel number identifier and receiving a digital broadcasting signal on the public carrier frequencies; for a selected specific program, searching for all broadcasting carrier frequencies of the selected specific program according to the received program information list, and performing reception by selecting the carrier frequency with a best signal quality; in a program reception process, monitoring the quality of a signal of another broadcasting carrier frequency; and if the quality of a signal of the current receiving carrier frequency reduces, continuing to receive the program by switching to another carrier frequency with better quality. By using the method and the system, large-area continuous coverage and seamless listening of a program can be implemented.
