Others are the same.

The details of these cells C-1 to Cn are as follows.
For example, in the case of the cell C-1, it is composed of M video object units V-1 to VM as shown as a fourth layer d.

The video object units V-1 to V-1
Details of -M include, for example, the NAVI pack composed of navigation data, the A pack composed of audio data, and the main video data, as shown in the fifth layer e for details of the video object unit V-1. V pack
One unit of video object unit V is obtained by combining an appropriate number of SP packs composed of sub-picture data.
It is assumed to be -1.

Therefore, when practicing a language, it is necessary to perform language learning while viewing a main video and a main audio displayed based on the main video data and watching a sub video (subtitle) reproduced in the sub video data. In this case, since a plurality of languages can be selected, the user can select a sub-picture (subtitle) in a desired language.

In this case, when performing a language practice using subtitles corresponding to each of a plurality of languages, first, the first language is selected, and the main video, main audio and sub-video are reproduced. After driving the completed track in the reverse direction, the second language is selected again, and the main video, the main audio, and the sub video are reproduced again, so that the sub video corresponding to the two languages can be sequentially obtained.

In addition to switching and displaying the subtitles in multiple languages by switching the sub-video, the main audio data added to the main video and Japanese and Japanese
When reproducing an information-recorded medium on which a plurality of sub-audio data corresponding to a plurality of languages such as English is recorded, a desired sub-audio is selectively and repeatedly reproduced.

The main processor 15 includes a memory 15a for storing read / write data required for performing repetitive reproduction in different languages, and a key operation unit 16 connected to the sub processor 2 comprises: It has a plurality of operation keys for giving commands such as "regular playback, forward fast-forward playback, reverse fast-forward playback, pause, track designation", etc. It includes a "practice key 16a" for setting a practice mode for language practice and a "language key 16b" for selecting a language to be repeatedly reproduced.

The main processor 15 obtains a main video component, an audio component, and a sub video component based on the optical signal read from the disk D, and converts the respective components into a main video decoder 8, an audio decoder 9, and a sub video decoder 10. The video signal is demodulated and input to a reproduction processing unit 11, and a final video signal obtained by performing a code error correction process and a D / A conversion process by the reproduction processing unit 11 is supplied to a video monitor 12, and a left audio signal is output. The output signal is supplied to the left speaker 13, and the right audio output signal is supplied to the right speaker 14.

The multilingual information reproducing apparatus thus configured needs to be set up prior to actually using the language practice function.
The user makes various settings while viewing the screen displayed on the screen, for example, while interacting with the display screen 12a shown in FIG. At the top of the display screen 12a, a title display of "language practice setup" is displayed, and at the center of the display screen 12a, a language selection window in which a list of multilingual languages such as "Japanese, English, French, and German" is displayed. The selected language is displayed on the set language list located on the right side. Further, selection buttons for setting a repetition time, that is, selection buttons for “short”, “medium”, and “long” are displayed at a lower portion of the display screen 12a.

This selection button repeatedly reproduces one video object VOBU (see FIG. 5) when "short" is selected, and repeats two video objects VOBU when "medium" is selected. It is set to reproduce three video objects VOBU repeatedly when "Long" is selected.

Therefore, by performing the setting operation in an interactive manner using the display screen 12a, a plurality of languages to be repeated are specified, and the repetition time is simultaneously set to the video object.
The number of VOBUs is specified.

Therefore, the practice key 16a of the key operation unit 16
