Method and apparatus for supporting a priority data transmission in a transmitter of a digital audio broadcasting system

摘要

A method and apparatus for supporting a priority transmission of broadcasting data in a transmitter of a digital broadcasting system. A determination is made as to whether a priority transmission of one broadcasting service to be provided is supported. If the service supports the priority transmission, a plurality of subchannels to be transmitted for the service are set and a priority of the data to be mapped to the plurality of subchannels is set. The data of the broadcasting service is mapped to the plurality of subchannels according to the priority. Data streams mapped to the plurality of subchannels are encoded in different encoders and the encoded data streams are transmitted.
