Abstract:
1. A method of processing signal, the method of processing: receiving broadcast signals including service channel component which contains audio data and channel information component which contains configuration information of the service channel component, the audio data encoded by a data coding scheme; obtaining data coding identification information indicating the data coding scheme among at least a pilot coding scheme and a differential coding scheme, wherein the differential coding scheme includes at least one of a frequency differential coding scheme and a time differential coding scheme; and decoding the audio data according to the pilot coding scheme identified by the data coding identification information and obtaining data elements of the audio data by using a pilot reference value and one or more pilot difference values which are generated using the data elements and the pilot reference value, wherein a quantity of the pilot difference values is equal to a quantity of the data elements of a current group, the pilot reference value is a single value which applies to all of the data elements of the current group, and each pilot difference value corresponds to each data element of the current group.
