Abstract

The invention discloses a method and device for transmission, distribution and receiving of data of a digital audio broadcasting system in China. The method comprises receiving digital audio broadcasting service data, generating service description information corresponding to the digital audio broadcasting service data according to a preset principle, carrying out coding distribution on the digital audio broadcasting service data, the service description information and preset system transmission parameters, packing the digital audio broadcasting service data, the service description information and the preset system transmission parameters to be data transmission frames with a fixed length, and carrying out transmission distribution on the data transmission frames with a fixed transmission rate according to a generating sequence. Through the technical scheme of the method, the method and device not only is suitable for the digital audio broadcasting system in China, but also can effectively guarantee the robustness of the data transmission of the system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for data transmission distribution and reception suitable for a digital audio broadcasting system in my country. Background technique [0002] Digital audio broadcasting is an important part of the digitization process of radio, film and television. It is an audio program broadcasting system that is fully digitized from program production, transmission and distribution, signal coding and modulation, transmission and receiving and decoding. [0003] Compared with the existing analog broadcasting such as FM and AM, the digital audio broadcasting system has the advantages of good sound quality, high spectrum utilization rate, large-area single-frequency network coverage, high receiver sensitivity, and good mobile reception performance. Due to the advantages of digitization, the digital audio broadcasting system can transmit a variety of value-added data se...
