Claim:
A digital broadcasting receiver comprising: a receiving unit to receive a transport stream comprising a first type stream comprising corresponding audio data and video data, and a second type stream comprising the audio data different in broadcast time from the audio data and the video data in the first type stream; and a broadcast output unit to selectively process the first type stream or the second type stream and to output the processed stream, wherein the audio data comprised in the first type stream is a same audio data as the audio data comprised in the second type stream other than a difference in the broadcast time, wherein the broadcast output unit comprises: a storage unit to store the audio data contained in the second type stream; a reception signal processor to selectively process the audio data and the video data contained in the first type stream and the stored audio data of the second type stream, and to output the processed data; and a control unit to control the reception signal processor to process the audio data stored in the storage unit and to output the processed audio data, when the control unit determines it is not possible for the digital broadcasting receiver to normally output the audio data and the video data in the first type stream, and to control the reception signal processor to process and output the audio data and the video data in the first type stream when the control unit determines it is possible for the digital broadcasting receiver to normally output the audio data and the video data of the first type stream.
