  • PBC”

    , the method comprising;

    receiving broadcast signals including video stream and audio stream from an internet network;

    demultiplexing the broadcast signals into the video stream and the audio stream, the audio stream including audio data encoded by a data coding scheme;

    extracting a pilot reference value and pilot difference values from a group included in the audio data; and

    obtaining data elements by adding the pilot reference value and the pilot difference values,wherein;

    the pilot reference value is decided by using each of the data elements of the group,the pilot reference value is a single value which applies to all of the data elements of the group,each pilot difference value of the group is decided by using each data element of the group and the pilot reference value, anda number of the pilot difference values of the group is equal to a number of the data elements of the group.
