    • The present invention relates to a method and apparatus for processing a signal. An object of the present invention devised to solve the problem lies on a method and apparatus for processing a signal, which allows a signal having optimized signal transmission efficiency to be transmitted/received. According to an aspect of the present invention, there is provided a method of processing a signal including receiving a broadcasting signal including audio data coded using a pilot reference value and a pilot difference value, demodulating the broadcasting signal in consideration of a scattered pilot which varies over time and a continual pilot which is fixed over time in a frame of the received broadcasting signal and decoding the demodulated signal to obtain a broadcasting transmission stream, demultiplexing the broadcasting transmission stream to obtain coded audio data in an Internet protocol (IP) packet and an identifier for identifying a method of decoding the audio data, obtaining the pilot reference value corresponding to a plurality of data and the pilot difference value corresponding to the pilot reference value from the coded audio data and obtaining the audio data using the pilot reference value and the pilot difference value.
    • 本发明涉及一种处理信号的方法和装置。 解决问题的本发明的目的在于一种用于处理信号的方法和装置,其允许发送/接收具有优化的信号传输效率的信号。 根据本发明的一个方面,提供一种处理信号的方法,包括接收包括使用导频参考值和导频差值编码的音频数据的广播信号,考虑到变化的散射导频解调广播信号 随着时间的推移,以及在接收的广播信号的帧中随时间而固定的连续导频,并解码解调的信号以获得广播传输流,解复用广播传输流以获得互联网协议(IP)分组中的编码音频数据,以及 用于识别对音频数据进行解码的方法的标识符,从编码的音频数据获得与多个数据相对应的导频参考值和与导频参考值相对应的导频差值,并使用导频参考值获得音频数据;以及 导频差值。
