Abstract
A choice specifying unit 500 specifies, as displayable subtitles, standard subtitles which a subtitle processing unit 300 can decode using a standard function, and expanded subtitles which the subtitle processing unit 300 can decode by an application processing unit 900 executing character expansion applications that can be obtained from data broadcasting. A user interface unit 200 displays a subtitle switching screen on a monitor 30 as a user interface which can present the specified displayable subtitles as choices of switchable subtitles when a user presses a “Subtitle” button, and in the subtitle switching screen the user can select one subtitle out of the presented choices as a subtitle to be superimposed on an image.
