The control means 8 includes a file analysis unit 8a for analyzing the contents of the auxiliary information file 4 of the recording medium 1 stored in the auxiliary information storage unit 7, a language code determination unit 8b for determining the language code, and a language of the determined language. A text data selection unit 8c that selects tag information in the same language as the text data, and a storage unit 8d that stores tag language information. Then, a content reproduction signal is output from the output terminal 12 of the content output means 6, and a tag of the same language is added to the text data 4 a to 4 c of a specific language from the display control means 10 and output to the display unit 13. To do. The instruction control unit 9 is input with the instruction information of the reproduction instruction unit 11 that instructs the reproduction of the recording medium. This reproduction instruction means 11 may be constituted by a remote controller.

  FIG. 2 shows a directory structure diagram of the recording medium according to the embodiment of the present invention. In the root directory 16, content files such as an audio file 18, a still image file 19, and a moving image file 20 and an auxiliary information directory 17 for these contents are placed. In the auxiliary information directory 17, there are directories for each language such as a Japanese directory 21, a Japanese kana directory 22, and an English directory 23. The names of these directories 21 to 23 are language codes corresponding to the respective languages. For example, the name of the Japanese directory 21 is “1041”, the name of the Japanese Kana directory 22 is “33809”, and the name of the English directory 23 is “1033”. In the directory for each language, there are text data files 24 to 26 for each language. The text data files 24 to 26 are text information about the content files 18 to 20, and unique language codes exist for each language with respect to text data of all languages.

  Next, the operation during reproduction will be described with reference to FIGS.

  As described above, the auxiliary information file 4 recorded on the recording medium 1 is stored in the auxiliary information storage unit 7 of the playback device 2. Based on the information stored in the auxiliary information storage unit 7, the control means 8 determines the directory for each language in the auxiliary information directory 17 of the recording medium from the information stored in the auxiliary information storage unit 7 by the file analysis unit 8 a. The names 21 to 23 are analyzed, and the language code discriminating unit 8b discriminates the language codes. For example, when a directory named “1033” exists in the auxiliary directory 17, it is determined that this directory is the English directory 23 and the English text data file 26 is recorded. In this case, when reproduction of the recording medium is started by the reproduction instruction means 11, the content reproduction signal is output from the output terminal 12, and at the same time, the text information corresponding to the content being reproduced in the English text data file 26 is output. Is added to the tag language information storage unit 8 d in advance, and is output to the display unit 13 via the display control means 10.

  For example, when a directory of only one kind of language and its text data file are recorded in the auxiliary information directory 17, at the time of reproduction of the recording medium 1, the reproduction signal of the content is output at the same time as that one kind of language. The tag of the same kind of language is added to the text information corresponding to the content being reproduced in the text data file and output. When a plurality of languages of directories and text data files are recorded in the auxiliary information directory 17, one of the languages is selected by the text data selection unit 8 c of the control unit 8 of the playback device 2. As in the case where data of only one type of language is recorded, the tag of the same type of language stored in advance in the tag language information storage unit 8d is added to the text information of the selected text data file of one type of language. Append and output.

  Here, the content of the tag is, for example, in the case of a tag added to the artist name of the audio file, such as “Artist:”, “Artist ...”, “<Performer>”, etc. Any format is acceptable.

  The flow of the control means of the present invention is shown in FIGS. 3 and 4, and the reproduction method of the present invention will be described with reference to FIGS.

  First, the control unit 8 reads the text information 21 to 26 in the auxiliary information directory 17 recorded on the recording medium 1 by the reproducing unit 5 into the auxiliary information storage unit 7 (step S1). Next, in step S2, the language code of the text information is determined. Here, the text information is composed of text data files 24 to 26 for each language and directories 21 to 23 including the respective text data files. The name of the directory is a language code for each language. For example, the name of the Japanese directory 21 is “1041”, the name of the Japanese Kana directory 22 is “33809”, and the name of the English directory 23 is “1033”. For other languages, specific language codes are determined. Based on the name of this directory, the language code of the text information is discriminated, and which language text information is recorded on the recording medium. After the determination of the language code of the text information, tag information in the same language as the referenced text data is selected in step S3, and the tag text language information stored in the tag language information storage unit 8d in advance in step S4. Capture. In step S5, the tag of the tag information and the text information are output to the display unit when the content is reproduced.

  FIG. 4 shows the details of step 2 described above. In step S2a, it is determined whether or not the language of the text information of the content is “Japanese kana”. In step S2b, the language of the text information of the content is “English”. Is determined. If there is Japanese kana text information in step S2a, the process proceeds to step S2c to refer to the Japanese kana text data. If there is no Japanese kana text data, the process proceeds to step S2b to refer to the English text data. If it exists, the process proceeds to step S2d to refer to the English text data. If there is no English text data in step S2b, the process proceeds to step S2e to refer to the Japanese text data. In this case, when there are a plurality of pieces of text information of different languages, the priorities of the languages are Japanese kana, English, Japanese.
