  In a conventional DVD player, an interlace video signal and a progressive video signal can be simultaneously output from the interlace output means and the progressive output means. However, when the video signal is output simultaneously from the progressive output means and the digital output means, the digital video signal output from the digital output means has a higher resolution than the progressive video signal output from the progressive output means. The signal processing circuit must be provided, and the manufacturing cost increases. For this reason, in the conventional DVD player, the user selects either the progressive output means or the digital output means as the means for outputting the video signal.

  In the progressive output means, since it takes time to process the video signal from the interlace format to the progressive format, there is a difference between the video signal output from the DVD player and the audio signal synchronized with the video signal. . For this reason, the conventional DVD player has a function of setting the output timing of the audio signal to match the output timing of the interlace video signal, the output timing of the progressive video signal, or the output timing of the digital video signal by the user. There is something.

  As described above, since there are many setting items related to the reproduction of audio signals and video signals, the conventional DVD player displays these setting items in a hierarchy on the display, and the user can check each display item while checking the display contents. Can be set (for example, see Patent Document 1).
