Title: Reproduction device, reproduction method, reproduction program, and recording medium

Abstract: For a content-prerecorded large capacity disc-shaped recording medium, a user interface having high flexibility is accomplished. Button image data, corresponding sound data as an effect sound, and control commands for the sound data and image data are multiplexed with a stream and recorded on the disc. A scenario reproduced from the disc is stored in a buffer. The image data and sound data are stored in a buffer. Image data is read from the buffer in accordance with a scenario and expanded to a graphics plane. In addition, corresponding sound data is read from the buffer and reproduced by a sound player. When a button image is varied in accordance with a state change of the button, an effect sound is reproduced. As a result, a more effective user interface is accomplished.
