Further, the system controller 9 can change the language setting of the OSD for displaying the initial setting menu or the like by the output from the operation unit 11. The user can use the operation unit 11 to set the OSD language setting, audio language, subtitle language, menu language, and the like. The system controller 9 stores setting contents such as OSD language setting, audio language, subtitle language, and menu language in the EEPROM 12.

  Hereinafter, the operation and action of the disk reproducing apparatus configured as described above will be described.

  FIG. 5 is a flowchart showing the operation of the disc playback apparatus of the present invention.

  First, in step S100, the system controller 9 determines whether or not the OSD language setting has been changed by the user. If it is determined in step S100 that the language setting of the OSD has been changed, the system controller 9 determines in step S101 the audio language setting, subtitle language setting, which are initially set in the video manager information and the video title set information. The menu language setting is changed to the OSD language code set by the user.

  Here, the process of step S101 will be described in detail. The OSD language code set by the user is stored in the EEPROM 12 as described above. In step S 101, the system controller 9 rewrites the default language codes such as the audio language, subtitle language, and menu language in the memory 8 to the same codes as the OSD language codes stored in the EEPROM 12. As a result, the OSD language set by the user is automatically reflected in the audio language, subtitle language, menu language, and the like. By the processing in step S101, for example, the initial language code for audio stream (INI_LCD) of the system parameter 16 (SPRM (16)) stored in the memory 8 is changed to the OSD language code set by the user. . Further, the initial language code (INI_LCD) for the sub-picture stream in the system parameter 18 (SPRM (18)) stored in the memory 8 is changed to the OSD language code set by the user. Further, the menu description language code (M_LCD) of the system parameter 0 (SPRM (0)) stored in the memory 8 is changed to the OSD language code set by the user. In step S102, the system controller 9 performs a DVD playback operation according to the audio language, subtitle language, and menu language codes stored in the memory 8. Therefore, in step S101, when the language code that is initially set is changed to the OSD language code set by the user, the DVD playback operation is performed using the OSD language code.

  In the above embodiment, the configuration in which the system controller 9 automatically changes the audio language, subtitle language, and menu language when the OSD language setting is changed is exemplified. However, the disk reproducing apparatus according to the present invention is not limited to this, and the user may be able to select whether or not the setting is automatically changed.

  In the present embodiment, an example in which the OSD language set by the user is automatically reflected in all of the audio language, the subtitle language, and the menu language has been described. Any configuration that is reflected in at least one is included in the technical scope of the present invention.

  As described above, in the present embodiment, the OSD language setting is automatically reflected in the audio language, subtitle language, and menu language settings, so that the user can make various initial settings for the audio language, subtitle language, and menu language. Thus, the DVD can be played back with the optimum settings for the user without complicated settings by the user.

  In this embodiment, a DVD playback apparatus is shown as a specific example of the playback apparatus. However, the present invention is not limited to any recording medium other than a DVD as long as the recording medium records content corresponding to a plurality of types of languages. It can be applied to a playback device.

  The disc playback apparatus according to the present invention automatically reflects the OSD language setting on other initial setting items of the disc playback apparatus, so that there are many setting items and the setting operation is very complicated. It can also be used for setting purposes.
