Abstract: A digital broadcast playback device for playing back AV content included in a broadcast program and executing an application included in the broadcast program is provided. A playback mode management unit manages whether the AV content is to be played in a real-time mode or in a time-shift mode. A section analysis unit acquires applications included in the broadcast program and information showing activation conditions of the respective applications, from a digital stream containing the broadcast program. A filtering unit selects an application whose activation condition is the real-time mode if the AV content is to be played in the real-time mode, and an application whose activation condition is the time-shift mode if the AV content is to be played in the time-shift mode. An application execution unit activates the selected application, with playback of the AV content.
