Abstract:
A broadcast receiving apparatus in the present invention includes: a first audio data characteristics extracting unit extracting a first soundless period and first interval information from first audio data included in the first service; a second audio data characteristics extracting unit extracting a second soundless period and second interval information from second audio data included in the second service; a simulcast determining unit determining whether or not the broadcast waves are simulcast by comparing the first interval information with the second interval information; and a broadcasting switching control unit switching between (i) the output of the audio data and the video data included in the first service and (ii) the output of the audio data and the video data included in the second service based on a result of the determination by the simulcast determining unit.
