Abstract
The digital broadcast receiver according to the present invention includes: a signal separating section that separates a main audio signal and a video signal from a decoded digital broadcast signal, and when the decoded digital broadcast signal includes the sub-audio signal, further separates the sub-audio signal; an audio generating section that decodes the main audio signal to generate a decoded main audio signal, and decodes the sub-audio signal, when it has been further separated, to generate a decoded sub-audio signal; a video generating section that decodes the video signal to generate a decoded video signal; a detecting section that detects an input to the audio generating section of the separated sub-audio signal; and a control section that, when the detecting section has detected an input of the sub-audio, controls the video generating section to further generate a sub-audio image signal to display a sub-audio image indicating the presence of sub-audio.
