Provided are a Blu-ray Disc (BD) playback system, a BD playback device, a display device, and a computer program which can report the status to the user during playback of BD content and can automatically provide an optimal user interface (UI). A BD playback device (110) is provided with an interactive content decision unit (113) for analyzing control data received from a disc reader (111) and determining whether a disc contains interactive content, and, if there is content, whether the interactive content should be played back. In addition, a display and operating device (120) is provided with an HMI control unit (123) for determining the status of the BD playback device (110) from the input from a communication unit (124) and displaying the appropriate HMI. The HMI control unit (123) controls the report to the user that interactive content exists when it has been determined that interactive content exists. |
