  In the navigation device disclosed in Non-Patent Document 1, a large amount of music can be recorded according to the capacity of the HDD. However, as the amount of recorded music increases, it becomes more difficult to find and play the music that the user wants to hear. For this reason, there is a need for a method of appropriately selecting and playing music from a large number of music recorded on the HDD according to user preferences.

The in-vehicle information terminal according to the first aspect of the invention relates to a recording means for recording music data in units of music by associating at least one of a specific artist name, track name, or album name with each music piece, An input means for inputting a keyword for searching for any one of the music pieces, a search means for searching for a plurality of music pieces from the recording means based on the keyword input by the input means, and a plurality of pieces searched by the search means It comprises sorting means for rearranging the music according to preset sorting conditions, and reproduction output means for reproducing and outputting a plurality of songs rearranged by the sorting means in the order of arrangement.
According to a second aspect of the present invention, in the in-vehicle information terminal according to the first aspect, the rearrangement condition includes at least one of a music reproduction time or a number of reproductions based on a past reproduction history.
According to a third aspect of the present invention, in the in-vehicle information terminal of the first aspect, the vehicle-mounted information terminal further includes a current position detecting unit that detects a current position of the vehicle. This includes the geographical relationship with the regional characteristics of each.

  According to the present invention, it is possible to appropriately select and reproduce music according to the user's preference from among music recorded in large quantities in the recording means of the in-vehicle information terminal using an HDD or the like.

  FIG. 1 shows the configuration of an in-vehicle navigation device with a music data recording / playback function according to an embodiment of the present invention. The navigation device 1 has a general navigation function for guiding a vehicle to a destination by displaying a recommended route from the departure point to the destination on a map. In addition, it has a recording / playback function for music data that is recorded and recorded from a music CD, and played back and output as needed. As shown in FIG. 1, the navigation device 1 includes a navigation unit 10, a music data recording / reproducing unit 11, a monitor 12, an HDD 13, and a CD / DVD drive 14. The music data recording / reproducing unit 11 is connected to an audio device 2 for outputting an input audio signal to a speaker (not shown) to output audio.

  The navigation unit 10 detects the current location of the host vehicle based on an arithmetic processing unit 101 configured using a microprocessor, a ROM, a RAM, and the like, and a GPS signal received from a GPS satellite, a detection result of a motion state of the host vehicle, and the like. A current location detection unit 102 and an input operation unit 103 for receiving a request input from the user. When the destination is set by the user via the input operation unit 103, the current location is detected using the current location detection unit 102, and then the map data recorded in the HDD 13 is read out by the arithmetic processing unit 101 to perform well-known navigation. Process. In this way, the navigation unit 10 obtains a recommended route from the current location to the destination, and displays a map for guiding the vehicle to the destination on the monitor 12, thereby realizing a navigation function in the navigation device 1.

  As described above, the user can request the navigation device 1 to execute the navigation function by setting the destination by operating the input operation unit 103. Further, the user can request the navigation apparatus 1 to execute the recording / playback function of music data by operating the input operation unit 103. When a request for the music data recording / playback function is made by the user, the content of the request is notified to the music data recording / playback unit 11. As the input operation unit 103, for example, a touch panel integrated with the monitor 12, a remote controller, or the like can be used.

  The music data recording / reproducing unit 11 is a component for executing recording / reproducing processing of music data in response to a request from the user, and includes a control unit 111 and a reproduction output unit 112. When recording music data, the control unit 111 controls the HDD 13 and the CD / DVD drive 14 to read music data from the music CD set in the CD / DVD drive 14 and write it to the HDD 13. Such a process is called ripping. The written music data is recorded on the HDD 13 in units of music.

  On the other hand, when playing back music data, either the music data recorded on the HDD 13 by the above-described ripping process or the music data recorded on the music CD set in the CD / DVD drive 14 is stored in the music. Can be played in units. The control unit 111 controls either the HDD 13 or the CD / DVD drive 14 to read the music data, and the reproduction output unit 112 converts the music data into an audio signal, whereby the audio signal is output to the audio device 2. The music is reproduced and output from the speaker. At this time, the ripping process can be performed in parallel with the reproduction of the music CD.

  When recording music data in the HDD 13, the song name (track name) and artist name are also recorded. It is also possible to record in the HDD 13 in units of albums in which a plurality of songs are combined. In this case, the album name is also recorded together with the track name. Note that it is sufficient that at least one of the artist name, the track name, and the album name is recorded together with the music data, and not all of them are required. That is, the HDD 13 records music data in units of music by associating each music with at least one of a specific artist name, track name, or album name.

  The user operates the input operation unit 103 to input characters included in any of the artist name, track name, or album name as keywords, thereby reproducing what is desired to be reproduced from the music data recorded on the HDD 13. The navigation device 1 can be searched. When a keyword is input, a song having any of the artist name, track name, or album name including the keyword is searched from the HDD 13. That is, the HDD 13 searches the HDD 13 for music associated with at least one of the artist name, track name, and album name including the input keyword. For example, when the character “AB” is input as a keyword, a song including the character string “AB” in any of the artist name, track name, or album name is searched. By searching for music containing the keyword input by the user in this way, it is possible to easily search for music that the user wants to search from among many music recorded in the HDD 13.

  The state of the keyword search for music as described above will be described with reference to the display screen examples of FIGS. FIG. 2 shows an example of a screen displayed on the monitor 12 when a search keyword is input. In the input button group 21 in which various buttons such as alphabets and numbers are arranged by the operation of the input operation unit 103 by the user, the “W” and “A” buttons are sequentially designated by the user and the character string “WA” Is input as a keyword, the keyword is displayed in the keyword display field 22. Then, the HDD 13 searches the HDD 13 for a song that includes the character string of the input keyword “WA” in any of the artist name, track name, or album name, and displays the number of songs in the number display column 23. In this example, since “73” is displayed in the number display column 23, a total of 73 songs that include the character string “WA” in any of the artist name, track name, or album name are searched. I understand that.

  If the keyword “WAI” is further input by continuing to input the keyword, the search result is narrowed down and a screen as shown in FIG. 3 is displayed on the monitor 12. In this case, since “2” is displayed in the number display column 23, it has been found that two music pieces including the character string “WAI” in any of the artist name, the track name, or the album name are searched. I understand. When the display button 24 labeled “Display” on this screen is selected by the user, the screen shown in FIG. 4 is then displayed.

  Note that by selecting the cancel button 25 labeled “return” on the screen of FIG. 2 or FIG. 3, the user can delete the entered keyword one character at a time as necessary. Also, by selecting the input mode conversion button 26 labeled “Kana”, the screen is switched to a screen in which various input buttons such as hiragana and katakana are arranged in the input button group 21 as the input screen. You can also. Furthermore, a plurality of keywords can be input by selecting a plurality of keyword designation buttons 27 labeled “AND”.

  FIG. 4 is an example of a screen on which the search result based on the keyword “WAI” is displayed on the monitor 12, and shows an example in which songs with track names “Wait & Look” and “Waiting for you” are displayed as a list. . Here, uppercase and lowercase letters of the alphabet are not distinguished, but may be distinguished. Also, here, the music whose track name includes the keyword “WAI” is listed as a search result, but if the music whose album name or artist name includes the keyword is recorded in the HDD 13, A list of those songs is displayed in the same manner.

  As described above, the corresponding music is searched from the music recorded on the HDD 13 based on the keyword input by the user, and the search result is displayed in a list. Each piece of music displayed as a list in this manner is reproduced and output to the speaker by the reproduction output unit 112 and the audio device 2 in the order of the list.

  Each music searched by the above keyword search is rearranged in display order according to a predetermined rearrangement condition when displayed as a list on the screen of FIG. Various contents can be used as the rearrangement condition at this time. For example, the music playback time may be used as a sorting condition so that the music is displayed in a list in order from the music with the shortest playback time. Alternatively, if a past playback history is recorded for each song, the number of playbacks represented by the playback history is used as a sorting condition, and a list is displayed in order from songs with the highest (or lower) number of playbacks. It can also be done. In addition, for example, various sort conditions such as the date of release or announcement of music and the music genre can be used.

  Alternatively, a rearrangement condition combined with the processing content of the navigation unit 10 may be used. For example, based on the current location detected by the current location detection unit 102, the presence or absence of a song including a place name or area name close to the current location is included in the track name or album name. It may be displayed. Alternatively, the travel location and travel road of the vehicle are determined from the current location detected by the current location detection unit 102, and the history is recorded in association with the music playback history. And when the traveling point and traveling road of a vehicle are the same as the past history, it is good also as carrying out a list display in an order from the music reproduced | regenerated at that time. As described above, the rearrangement condition can be the geographical relationship between the current location of the vehicle and the regional characteristics of each musical piece.

  If the list display order of the music searched for keywords as described above is rearranged, the playback order of the music is also determined accordingly, so that various effects according to the contents of the rearrangement condition can be brought about during the playback of the music. it can. For example, when music is arranged and reproduced in order from the music with the shortest reproduction time, as many music as possible can be reproduced within a certain time. In addition, when the songs are arranged side by side in descending order of the number of playbacks, the music that the user usually likes to listen to can be preferentially reproduced, and conversely, when the songs are arranged in order from the fewest number of times of reproduction, It is possible to preferentially play an unexpected music that the user does not listen to much.

  Or, as explained above, if the geographical relationship between the current location of the vehicle and the regional characteristics of each music is used as the sorting condition, the music that matches the surrounding scenery and atmosphere can be preferentially reproduced. it can. Even when rearrangement conditions other than this are used, various effects corresponding to the respective rearrangement conditions can be brought about during music reproduction.

  Note that which of the rearrangement conditions described above is used may be set in advance by the user or may be selected by the user every time a keyword search is performed. Furthermore, a plurality of rearrangement conditions may be used in combination.

  FIG. 5 shows a flowchart for executing the processing as described above. This flowchart is executed by the control unit 111. In step S10, a keyword is input. This is performed when the user inputs any character by the input button group 21 of FIG. 2 displayed on the monitor 12 as described above. When a keyword is input by the user, the process proceeds to the next step S20.

  In step S20, the corresponding music is searched from the HDD 13 based on the keyword input in step S10. At this time, a search is made for a song whose keyword is included in any of the artist name, track name, or album name. In the next step S30, it is determined whether or not to display the keyword search result in step S20 on the monitor 12. This determination is performed by detecting which one of the display button 24 and the input button group 21 is pressed by the user. When the display button 24 is pressed, it is determined that the search result is displayed, and the process proceeds to step S40. When any button of the input button group 21 is pressed, it is determined that the search result is not displayed, and the process returns to step S10, and characters corresponding to the button are continuously input to the keyword.

  In step S40, each music searched by the keyword search of step S20 is rearranged according to various rearrangement conditions as described above. In step S50, the search result of the music rearranged in step S40 is displayed as a list on the screen of the monitor 12. Thereby, a screen as shown in FIG. 4 is displayed.

  In step S60, the music data of the music is output to the reproduction output unit 112 according to the arrangement order displayed in the list in step S50. As a result, an audio signal is output from the reproduction output unit 112 to the audio apparatus 2 and the music is reproduced and output from the speaker. When step S60 ends, the flowchart of FIG. 5 ends. As described above, a keyword search for music is performed, the search results are rearranged, and each music is reproduced and output in order.

According to the embodiment described above, the following operational effects can be obtained.
(1) In the HDD 13, at least one of a specific artist name, track name, or album name is associated with each song, and music data is recorded in units of songs such as albums and tracks. Then, a keyword is input (step S10), and a plurality of songs are searched from the HDD 13 based on the keyword (step S20). The searched music pieces are rearranged according to the various rearrangement conditions as described above (step S40), and reproduced and output in the order of the rearrangement (step S60). Since it did in this way, it can select and reproduce | regenerate a music appropriately from a large amount of music recorded on HDD according to a user's liking.

(2) When rearranging a plurality of music pieces in step S40, assuming that the playback time of the music is used as the rearrangement condition and playing back music in order from the shortest playback time, play as many songs as possible within a certain time. can do. Also, if the number of playbacks based on past playback histories is used as the sorting condition, the songs that are frequently listened to by the user can be preferentially played if the songs are played back in descending order of the number of playbacks. If the music is played in order from the music with the smallest number of times of reproduction, it is possible to preferentially play an unexpected music that the user does not hear much.

(3) Or, when rearranging a plurality of music pieces in step S40, if the rearrangement condition is the geographical relationship between the current location of the vehicle and the regional characteristics of each music piece, it matches the surrounding scenery and atmosphere. Music can be played with priority.
