Description

  The present invention relates to an electronic device, a display control method, and a display control program for grouping and managing content data using tag information added to content data such as music data and selecting desired content data.

  As an example of an electronic device, music data compressed using an audio compression method such as MP3 (MPEG Audio Layer 3) or AAC (Advanced Audio Coding) is stored in a large-capacity recording medium such as a hard disk drive or flash memory. An audio playback apparatus that plays back desired music data has become widespread. This type of audio playback apparatus can store hundreds to thousands of songs. Therefore, music data is grouped and managed using tag information such as the genre, title, artist name, and album name of the music added to the music data so that a desired music can be easily selected.

  By the way, when the music recorded on the compact disc (CD) is compressed by a predetermined audio compression method and stored in the audio playback device, there is no tag information of the music on the CD. Therefore, it is common to obtain tag information from an external database that provides tag information of music pieces recorded on a CD, add tag information to music data, and store the data in a recording medium. The music tag information provided by the external database is information based on data registered by a large number of users. Therefore, the notation of tag information is not unified, and there may be a plurality of different notations even with substantially the same meaning.

  In the case of the genre of “pop” in the tag information, for example, “POP” using a single-byte uppercase alphabet, “POPS” with “S” for “POP”, and a single-byte lowercase alphabet. “Pop”, “pops” with “s” added to “pop”, “POP” using full-width capital letters, “POPS” with “S” added to “POP” can be used. Similarly, there can be a notation using a lower-case alphabet. Furthermore, “pop” using full-width katakana, “pops” with “s” added to “pop”, and notation using these half-width katakana characters can also be used.

  As an example, when an audio playback device displays a list of genres of music on a display unit in a list format, it is common to display a plurality of genres side by side in the order of character codes such as Unicode. If there is a genre of tag information added to the song data, “POP” using single-byte capital letters and “pop” using double-byte katakana, multiple other genres or double-byte characters using single-byte alphabets. If there are a plurality of genres using katakana, “POP” and “pop” are displayed at different positions. Here, the genre is taken as an example, but the same applies to the case where a list of titles, artist names, and album names is displayed in a list format.

  In this way, when there are multiple different notations in the tag information even though it is originally the same tag information, when the list of tag information is displayed in list format, it is displayed at a distant position There is. In such a case, there is a problem that the user may miss some of the plurality of tag information displayed at positions distant from each other.

  In the present invention, in view of such a problem, even when substantially the same tag information is added to a plurality of pieces of content data in different notations, when the tag information is displayed as a list, the user can select a part of the tag information. An object of the present invention is to provide an electronic device, a display control method, and a display control program that can greatly reduce the possibility of oversight.

  In order to solve the above-described problems of the prior art, the present invention extracts a content data storage unit (1) for storing content data to which tag information is added and content data stored in the content data storage unit. Tag information storage unit (31) for storing the tag information and tag information associated with tag information which is substantially the same tag information and which has different notation among the tag information read from the tag information storage unit When the tag information read from the association unit (7) and the tag information storage unit is displayed in a list on the display unit (9), each tag information is arranged according to a predetermined rule, and the tag information association A display control unit (8) for controlling a plurality of tag information associated with each other in different notations to be displayed adjacent to each other without following the rules. Obtaining possible to provide an electronic device (100), characterized in.

  In the above electronic device, it is preferable that the tag information associating unit associates tag information written in alphabet, which is substantially the same tag information, with tag information written in katakana.

  The electronic device further includes a tag information association database (6) that holds association data in which tag information that is substantially the same tag information and different notation is associated, and the tag information association unit is included in the tag information association database. You may comprise so that the tag information from which description may differ may be linked | related with reference to the hold | maintained correlation data.

  In the above electronic device, the tag information association unit may be configured to determine that the tag information is substantially the same by converting one of alphabet and katakana into the other.

  In the above electronic apparatus, when the display control unit displays the tag information written in alphabet and the tag information written in katakana adjacent to each other, the display control unit uses the katakana adjacent to the tag information written in alphabet. It is preferable to further include an arrangement condition setting unit (23) for setting whether to display the written tag information or to display the tag information written in alphabet adjacent to the tag information written in katakana.

  In the electronic device, the arrangement condition setting unit may be adjacent to the tag information expressed in katakana and the first pattern for displaying tag information expressed in katakana adjacent to the tag information expressed in alphabet. The second pattern for displaying the tag information expressed in alphabets may be selected based on a predetermined condition.

  In the electronic device, as the predetermined condition, the date and time information when content data is stored in the content data storage unit, tag information expressed in alphabets, and the number of times content data is included in tag information expressed in katakana, At least one of the number of content data included in the tag information expressed in alphabet and the tag information expressed in katakana can be used.

  In addition, the present invention provides a display control method using a tag information storage unit that stores tag information extracted from content data to which tag information is added in order to solve the above-described problems of the related art. A tag information associating step for associating tag information of substantially the same tag information but different notation among tag information read from the storage unit, and tag information read from the tag information storage unit are displayed. When displaying the list in a section, each tag information is arranged according to a predetermined rule, and a plurality of tag information associated with each other in the tag information association step is displayed adjacent to each other without following the rule. And a display control step for controlling the display control method.

  Furthermore, the tag information read out from the tag information storage unit is substantially transmitted to the computer of the electronic device including the tag information storage unit that stores the tag information extracted from the content data to which the tag information is added. A tag information associating step for associating tag information with the same tag information but different notations, and tag information read from the tag information storage unit when the list information is displayed on the display unit, And a display control step for controlling to display a plurality of tag information associated with each other in the tag information associating step adjacent to each other without following the rule. Provide a control program.

  According to the electronic device, the display control method, and the display control program of the present invention, even when substantially the same tag information is added to a plurality of pieces of content data with different notations, the user can display the tag information as a list. Can greatly reduce the possibility of overlooking some tag information.

It is a block diagram which shows one Embodiment of the electronic device of this invention. It is a figure which shows an example of the correlation data which the tag information correlation database 6 of FIG. 1 hold | maintains. It is a flowchart which shows an example of the correlation determination process performed in the tag information correlation part 7 of FIG. It is a figure which shows the example of the list display by this embodiment. It is a figure which shows the other example of the list display by this embodiment.

  Hereinafter, an electronic device, a display control method, and a display control program according to an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an audio playback device 100 as an embodiment of an electronic device. The audio playback device 100 may be a portable audio device or a stationary audio device. In the audio reproduction device 100 according to an embodiment, the display control method according to an embodiment for displaying tag information extracted from content data to which tag information is added on a display unit is executed. Display of tag information on the display unit can also be realized by a computer program (display control program).

  In the following explanation, the difference between two pieces of predetermined tag information is a difference whether it is an katakana notation that is an alphabetic notation, a difference whether it is an uppercase notation or a lowercase notation, a half-width notation or a full-width notation The two tag information is called “substantially the same tag information” if the difference is “s”, “su”, “es”, or the like. And However, these differences are examples, and the present invention is not limited to these. For example, when parentheses are included like “Domestic (J-Pops)”, “Domestic (J-Pops)” and “J-Pops” are regarded as “substantially the same tag information”. You can also

  In FIG. 1, a music storage unit (content data storage unit) 1 stores, as an example of content data, a plurality of music data compressed using an audio compression method such as MP3 or AAC. The music storage unit 1 is a large-capacity recording medium such as a hard disk drive or a flash memory. As an example, tag information such as the genre, title, artist name, album name, etc. of the song is added to each piece of music data. There are various methods for adding and storing music data in the music storage unit 1. In the present embodiment, the control unit 2 takes in music data stored in a flash memory 15 called a so-called USB memory via the interface (I / F) 4, and writes / reads control unit in the control unit 2. 22 is configured to write music data in the music storage unit 1. The audio reproduction device 100 may be connected to a personal computer (not shown), and music data may be written to the music storage unit 1 from the personal computer.

  Tag information added to music data stored in the music storage unit 1 is extracted by a tag information extraction unit 21 in the control unit 2 and supplied to the database unit 3. The tag information storage unit 31 in the database unit 3 stores tag information input to the database unit 3. For example, the tag information storage unit 31 associates each genre with the artist name included in each genre, associates each artist name with the album name of each artist, and includes each album name in each album. Each tag information is stored in a state in which the titles to be associated are associated.

  The date / time information storage unit 32 in the database unit 3 stores, for each piece of music data, the date / time data obtained by storing the music data in the music storage unit 1 as described above. The control unit 2 manages date / time information, and the date / time data is supplied from the control unit 2 to the database unit 3. The reproduction number storage unit 33 in the database unit 3 stores the number of times the music data stored in the music storage unit 1 has been reproduced by the reproduction unit 10 described later for each piece of music data. The control unit 2 manages the number of reproductions of each piece of music data, and the data on the number of reproductions is supplied from the control unit 2 to the database unit 3.

  Selection and reproduction of music data are performed by an operation by the operation unit 5. The operation unit 5 may be an operation button provided on the housing of the audio playback device 100 or a remote controller.

  The tag information association database 6 is data indicating how a plurality of different representations of tag information are related, specifically, which representation of tag information and which representation is substantially the same tag information ( Association data). FIG. 2 conceptually shows an example of association data held by the tag information association database 6. Here, genre association is shown. As shown in Fig. 2, in the genre of “Blues”, “BLUES” using a half-size uppercase alphabet is used as a basic notation. Are associated. Consensus notation for the basic notation “BLUES” is “blues” using a half-width lowercase alphabet, “BLUES” using a full-width lowercase alphabet, “blues” using a full-width lowercase alphabet, and “full-width katakana” “Blues” and half-width katakana.

  In the genre of “pop”, “POP” using a single-byte uppercase alphabet is used as a basic notation, and ten notations according to consent are associated with this basic notation “POP”. In FIG. 2, the notation using the single-byte uppercase alphabet is used as the basic notation. However, as shown in “Pop”, it is also possible to use the single-byte uppercase alphabet only for the beginning of the word and the single-byte lowercase alphabet as the basic notation. . If the basic notation is a single-byte uppercase alphabet with only the first letter and the character following the first letter is a single-byte lowercase alphabet, there will be many more different notations.

  Based on the tag information stored in the tag information storage unit 31, when displaying any list of tag information on the display unit 9 in a list format, the tag information is sent via the control unit 2 to the tag information. It is supplied to the associating unit 7 and the display control unit 8. Note that displaying a list of tag information in order to select a desired music piece is called tag browsing. The tag information association unit 7 refers to the association data in the tag information association database 6 and determines which tag information is the same as which tag information. For example, when “POP” and “pop” exist as genres of tag information, the tag information association unit 7 determines that both are the same genre by referring to the association data shown in FIG. can do.

  Here, it is determined that the tag information is the same based on the association data held in the tag information association database 6. However, the tag information is analyzed by analyzing the notation (words) itself of the tag information. You may make it judge. A process in the case where the tag information association unit 7 analyzes the tag information notation itself and determines that the tag information is the same will be described with reference to FIG. The genre is taken as an example in FIG.

  Each step of FIG. 3 is executed by the tag information association unit 7. In FIG. 3, in step S1, the genre in the tag information added to the music data is read. In step S2, it is determined whether or not it is a full-width alphabet. If it is determined in step S2 that it is a full-width alphabet (YES), full-width is converted to half-width in step S3, and the process proceeds to step S4. If it is not determined in step S2 that it is a full-width alphabet (NO), the process proceeds to step S4. In step S4, it is determined whether it is a lowercase alphabet. If it is determined in step S4 that it is a lowercase alphabet (YES), lowercase letters are converted to uppercase letters in step S5, and the process proceeds to step S6. If it is not determined in step S4 that it is a lowercase alphabet (NO), the process proceeds to step S6.

  In step S6, it is determined whether or not “S” or “ES” is added to the end of the word. If it is determined in step S6 that “S” or “ES” is added to the end of the word (YES), in step S7, the same alphabet character string as the alphabet character string preceding “S” or “ES”. Are regarded as the same genre, and the process proceeds to step S8. If it is not determined in step S6 that “S” or “ES” is added to the end of the word (NO), the process proceeds to step S8. In step S8, it is determined whether or not it is an alphabet. If it is determined in step S8 that it is an alphabet (YES), it is converted into Japanese readings in step S9, and the process proceeds to step S10. If it is not determined that it is an alphabet in step S8 (NO), the process proceeds to step S10.

  In step S10, it is determined whether or not it is a half-width katakana. If it is determined in step S10 that it is a half-width katakana (YES), it is converted to a full-width katakana in step S11, and the process proceeds to step S12. If it is not determined in step S10 that it is a half-width katakana (NO), the process proceeds to step S12. In step S12, “su” is added to the end of the word, and the same character string as the character string before “su” is regarded as the same genre, and the process is ended. As a method for converting the alphabet into Japanese reading in step S9, a technique as described in Patent Document 3 may be adopted as an example.

  There are cases where parentheses are included in the genre notation such as “Domestic (J-Pops)”. In this case, “Domestic (J-Pops)” and “J-Pops” can be regarded as the same genre. The method of determining identity is arbitrary.

  In FIG. 3, the alphabet is converted to katakana to determine the identity of the genre, but the katakana may be converted to alphabet to determine the identity of the genre. In FIG. 3, the genre is taken as an example, but the same applies to the title, artist name, and album name of the music. As shown in FIG. 3, when the tag information association unit 7 analyzes the tag information notation itself and determines that the tag information is the same, the tag information association database 6 can be deleted.

  In addition, when using a character code as a rule for arranging tag information, for example, when displaying “POP” of the half-size uppercase alphabet and “pop” of the half-size lowercase alphabet, “POP” and “pop” are adjacent or close to each other. Will not be displayed apart like "POP" and "Pop". Therefore, it may be simplified so as to determine only the identity of the tag information written in half-width alphabet and the tag information written in Japanese full-width characters (mainly katakana).

  By the way, since there are at most about 200 genres in the tag information, it is relatively easy to create a database of association data. However, the titles, artist names, and album names of songs are much more than genres, and are added daily. Thus, when tag browsing is performed, when the display method of the present embodiment described later is adopted only by genre, association data is held in the tag information association database 6 and identity is determined based on the association data. It is preferable. On the other hand, when the display method of the present embodiment, which will be described later, is also applied to the title, artist name, and album name of music, the identity is determined by analyzing the tag information notation as described in FIG. Is preferred.

  The display control unit 8 displays the tag information read from the tag information storage unit 31 on the display unit 9 with reference to the association information determined by the tag information association unit 7. By operating the operation unit 5, the user can select whether to perform tag browsing based on any of genre, title, artist name, or album name in the tag information. Based on the operation of the operation unit 5, the control unit 2 controls the display control unit 8 to perform tag browsing based on the selected tag information.

  An example of the list display displayed on the display unit 9 according to the present embodiment will be described with reference to FIGS. Here, taking a genre as an example, a case where “POP” and “pop”, which are essentially the same genre, will be described. For comparison, FIG. 4C shows a conventional display example not according to the present embodiment. The display control unit 8 normally displays a plurality of genres side by side according to a predetermined rule as in the order of character codes. When displaying in the order of character codes, a plurality of genres expressed in Japanese hiragana, katakana, and kanji are arranged and displayed after a plurality of genres expressed in single-byte alphabets. As described above, in the display method of FIG. 4C, “POP” using a single-byte capital letter alphabet and “pop” using full-width katakana are greatly separated, and the “pop” in which the user is positioned below is displayed. May be overlooked.

  Therefore, in the present embodiment, by displaying the association information determined by the tag information association unit 7, the pattern 1 shown in FIG. 4A or the pattern 2 shown in FIG. 4B is displayed. Can do. The pattern 1 shown in FIG. 4A displays “POP” located in the arrangement of the half-size uppercase alphabet so as to be located immediately after the “pop” of the full-width katakana without following the arrangement rules. It is an example. Pattern 2 shown in FIG. 4B is an example in which, contrary to pattern 1, a full-width katakana “pop” is displayed immediately after “POP” without following the rules of arrangement. In both patterns 1 and 2, since “POP” and “pop” are arranged adjacent to each other, there is almost no possibility that the user will miss one, and from both “POP” and “pop” It becomes possible to select a desired music piece.

  FIG. 5 shows pattern 3, which is another pattern. Pattern 3 shown in FIG. 5 is a combination of patterns 1 and 2. An example in which “POP” is positioned immediately after “POP” and “POP” is positioned immediately after “POP” is displayed. It is. In the example of FIG. 5, “POP” immediately after “POP” and “POP” immediately after “POP” are displayed shifted to the right from “POP” and “POP”, respectively. By doing so, it can be easily understood that the identity is judged and the supplementary display is performed. Instead of shifting the position of the character string to be displayed, or in addition thereto, the brightness may be varied, the color may be varied, or a predetermined mark may be attached.

  The user can operate the operation unit 5 to select any genre and select a desired song from a list of songs included in the genre. When a song is selected, the song data of the song selected by the control unit 2 is read from the song storage unit 1 and supplied to the playback unit 10. The playback unit 10 decodes the input music data, performs various signal processing such as amplification, and supplies the audio signal to the speaker 11. The speaker 11 outputs sound based on the audio signal input from the reproduction unit 10. By reproducing the music data, the number of reproductions stored in the reproduction number storage unit 33 is updated.

  The arrangement condition setting unit 23 in the control unit 2 sets what pattern is used for tag browsing. The arrangement condition setting unit 23 may preset one pattern as an arrangement condition, such as pattern 1 shown in FIG. 4A or pattern 2 shown in FIG. 4B, or may set a plurality of patterns. May be. The user may select from a plurality of patterns set by the arrangement condition setting unit 23 by operating the operation unit 5. Further, an optimum pattern can be automatically selected from a plurality of patterns based on various conditions.

  When the tag information is displayed in a list from the top to the bottom as shown in FIGS. 4A and 4B, it is easier for the user to find the tag information to be selected located above. When the user newly adds music data, there is a high possibility that the music of the added music data is selected. For example, when music data having a genre of “pop” is added, the pattern 2 shown in FIG. 4B is preferable. When the arrangement condition setting unit 23 sets the condition that the music data written in the music storage unit 1 is located at a higher position, the display control unit 8 is stored in the date information storage unit 32. Pattern 2 is selected based on the date / time information. The same applies when music data with the genre “POP” is added.

  Patterns 1 and 2 may be selected according to the number of times the music data is played. If the “pop” song data playback count is greater than the “POP” song data playback count, pattern 1 is used, and the “POP” song data playback count is “pop” song data playback. If it is more than the number of times, it is preferable to use pattern 2. If the number of songs included in “POP” and “pop” are different, the average number of reproductions may be compared. In this way, since the tag information with the smaller number of reproductions moves to the tag information with the larger number of tag information, the possibility of overlooking the tag information with the smaller number of reproductions can be reduced.

  Furthermore, you may move the one with few music data contained in tag information to the one with many. If there is more “pop” music data, pattern 1 is selected, and if there is more “POP” music data, pattern 2 is selected.

  As described above, in the present embodiment, substantially the same tag information is displayed adjacently. If the same tag information is integrated into one tag information, for example, the genre of “pop” is intentionally set for Japanese music and the genre of “POP” is set for Western music. This leads to a problem that it will end up. In this embodiment, since the images are displayed adjacent to each other, such a problem does not occur.

  The present invention is not limited to the embodiment described above, and various modifications can be made without departing from the scope of the present invention. The tag information added to the music data need not have all of the music genre, title, artist name, and album name, and may be at least one. In FIG. 1, the tag information association unit 7 and the display control unit 8 are provided outside the control unit 2, but may be provided inside the control unit 2. The control unit 2 can be configured by a microcomputer, and the tag information association unit 7, the display control unit 8, the tag information extraction unit 21, the writing / reading control unit 22, and the arrangement condition setting unit 23 can all be realized by the microcomputer. . The audio reproducing apparatus 100 may not include the speaker 11 but may output the audio signal to the outside and reproduce the audio signal through an external speaker.

  The audio playback device 100 is merely an example of an electronic device, and may be a playback device that plays back video data. A personal computer may also be used. Any electronic device may be used as long as it is an electronic device that groups and manages content data using tag information added to the content data and selects desired content data. The display control program may be provided by being recorded on a recording medium, or the display control program can be distributed using a communication line such as the Internet.
