When the process of step S205 is performed and it is determined that four types of lyrics data are requested, the lyrics management server 50 is requested to acquire the four types of lyrics data for the music that is determined to be reproduced. When the processing of step S207 or step S209 is performed, an acquisition request for the type of lyrics data determined to be acquired is transmitted to the lyrics management server 50 for the music determined to be played.

  For example, in step S210, if it is determined in step S15 that the song with the song ID “c” is to be played back, and it is determined in step S205 that all types of lyrics data are to be acquired, the song management unit 50 receives the song ID “c”. For the music, four types of lyrics data acquisition requests are transmitted. If it is determined in step S15 that the song with the song ID “c” is to be played, and it is determined in the process of step S207 or step S209 that the lyric data requested for acquisition is normal lyrics, A request for obtaining lyrics data of normal lyrics is transmitted for the song with ID “c”.

  In step S211, it is determined whether or not the type of lyrics data requested for acquisition from the lyrics management server 50 in step S210 has been acquired. If it is determined that the requested lyrics data has been acquired (step S211: YES), the process of step S212 is performed. If it is not determined that the requested lyrics data has been acquired (step S211: NO), the process of step S211 is repeated.

  In step S <b> 212, the types of lyrics stored in the display lyrics setting storage area 244 of the RAM 24 are displayed on the display 21. When the process of step S212 is performed, step S30 of FIG. 5 is executed. In step S212, when a plurality of types of lyrics data are acquired in step S211, any of the acquired types of lyrics can be displayed. The user can specify display of desired lyrics by touching a predetermined position on the display 21 where the type of lyrics is displayed. When the type of lyrics is designated by the user, the display device 20 switches the display 21 to the designated type of lyrics for display. In step S <b> 212, when lyrics are displayed on the display 21, the type of lyrics to be displayed is stored in the display lyrics setting storage area 244 according to the switching specification by the user.

  A specific example in which the type of lyrics data to be acquired differs depending on the setting status and usage status of each display device 20 when the lyrics acquisition processing in step S20 is performed will be described. When the display device 20 is in the setting state shown in FIG. 2A, the power saving mode is set to OFF, and the remaining battery level is 50%, so that the normal mode is set. In the normal mode, four types of lyrics data are acquired when the music is played in the music playback mode. When four types of lyrics data are acquired, as shown in FIG. 2E, the user touches the lyrics designation buttons 21a to 21c to switch the lyrics to be displayed on the display 21 from the four types of lyrics. .

  When the display device 20 is in the setting state shown in FIG. 2B, the power saving mode is set to ON, and the remaining battery level is 70%, so that the limit mode is set. In the restriction mode, when the music is played in the music playback mode, one type of lyrics data set to be displayed is acquired. When one type of lyric data is acquired, for example, when “normal lyrics” is specified by the user in the display lyric setting storage area 244 of the RAM 24, as shown in FIG. Usually, lyrics are displayed on the display 21. When one type of lyrics data is acquired, as shown in FIG. 2 (F), the lyrics designation buttons 21a to 21c for designating other types of lyrics are not displayed on the display 21, and the displayed normal lyrics are displayed. You cannot switch to other types of lyrics.

  In the lyric acquisition process, when the continuous playback mode is not determined, the illumination of the display 21 is ON, the power saving mode is OFF, and all the conditions that the remaining battery level is more than 30% are satisfied, the normal mode As a result, the process of step S205 is performed. When it is determined that the display is in the continuous playback mode and the illumination of the display 21 is ON, or when it is not determined that the display is in the continuous playback mode and the illumination of the display 21 is OFF, or is in the continuous playback mode. When the power saving mode is ON, or when it is determined that the continuous regeneration mode is not determined and the remaining battery level is 30% or less, the limit mode is set as step S207. Processing is performed.

  Also, in the lyrics acquisition process, it is not determined that the continuous playback mode is selected, and when it is determined that the illumination of the display 21 is OFF, the power saving mode is ON, or the remaining battery level is 30% or less, and continuous playback is performed. When the mode is determined and it is determined that the illumination of the display 21 is not OFF, it is determined that less than four types of lyrics data are requested. In step S207 shown in FIG. 6, it is determined that the lyrics management server 50 is requested to acquire the type of lyrics data stored in the display lyrics setting storage area 244. In step S208, it is determined whether or not the type of lyric data determined to be acquired in step S207 is “karaoke lyrics”. If it is karaoke lyrics, it is stored in the display lyrics setting storage area 244 in step S209. A process is performed in which the type of the lyrics being changed is changed to “normal lyrics”.

  When the song one song before the song decided to play is played, if the displayed lyrics type is “Karaoke Lyrics”, the lyrics are displayed in different colors in order as the song progresses. Therefore, the power consumption is large compared to the case where “normal lyrics” is displayed. Therefore, in step S209, the type of lyrics display mode stored in the display lyrics setting storage area 244 of the RAM 24 is changed so that lyrics other than “karaoke lyrics” are displayed. In step S209, when the restriction mode is set by changing the stored contents of the display lyrics setting storage area 244 to “normal lyrics”, the power is higher than that of “karaoke lyrics” when being displayed on the display 21. It is possible to display a kind of lyrics with low consumption.

  In step S30, the music determined to be played in step S15 is played. In step S40, it is determined whether or not there is a song designated to be played continuously with the song played in step S30, according to the playback order of the playlist. If it is determined that there is a piece of music to be played continuously (step S40: YES), the process of step S60 is performed. If it is not determined that there is a piece of music to be played continuously (step S40: NO), the process of step S50 is performed.

  In step S50, it is determined whether or not the music played in step S30 is a music for which repeat playback is designated by the user. If it is determined that the music is to be played back a plurality of times in succession (step S50: YES), the process of step S60 is executed. If it is not determined that the music is to be continuously reproduced a plurality of times (step S50: NO), the process of step S70 is performed.

  In step S60, the music to be played is designated. In step S40, if it is determined that there are songs to be played back continuously in the playlist for which the playback order is determined, the music to be played is designated according to the playback order of the playlist. If it is determined in step S50 that the music played in step S30 is a music for which repeat playback is designated, the music to be played back repeatedly is determined. Repeat playback includes one-track repeat playback in which one song is repeatedly played a plurality of times, and all-track repeat playback in which all songs in a playlist composed of a plurality of songs are repeatedly played back a plurality of times. In step S60, in the case of a song for which one-track repeat playback is set, the same song as the song played in step S30 is determined as the song to be played. In the case of music for which all-music repeat playback is set, the first music in the playlist is determined as the music to be played. If the process of step S60 is performed, the process of step S20 will be performed continuously.

  In step S70, it is determined whether or not the reproduction of the music has ended. If it is determined that the music has been played back (step S70: YES), the process of step S80 is performed. If it is not determined that the reproduction of the music has ended (step S70: NO), the process of step S70 is repeated.

  In step S80, it is determined whether an instruction to end the application software has been issued. If it is determined that an instruction to end the application software has been given (step S80: YES), the music reproduction display program is ended. If it is not determined that an instruction to end the application software has been given (step S80: NO), the process of step S10 is repeated.

(Modification)
In the present embodiment, in step S204 of the lyrics acquisition process, when the remaining amount of the battery power supply 28 is equal to or less than a predetermined value, a process of switching to a restriction mode that limits the type of lyrics to be acquired is performed. In the present embodiment, as an example of the criterion for switching to the limit mode, the threshold value of the remaining battery level is 30% or less, but the criterion for switching to the limit mode is not limited to this. For example, the limit mode may be set when the remaining battery threshold is 20% or less or 10% or less. The threshold value of the remaining amount for switching to the restriction mode may be predetermined in the program or may be designated by the user.

  In addition, the restriction mode for restricting the types of lyrics to be acquired may be set in a plurality of restriction modes in accordance with the remaining amount of the battery power supply 28. May be configured to request acquisition of the number of types of lyrics determined according to the stage of the restriction mode. For example, when the remaining amount of the battery power supply 28 is 80% or more, a request for acquisition of all four types of lyrics is made, and when it is 50% or more and less than 80%, the first restriction mode is used to acquire three types of lyrics. Request to obtain 2 types of lyrics as the second restriction mode when it is 30% or more and less than 50%, and request to obtain one type of lyrics as the third restriction mode when it is 30% or less Also good. Moreover, it is desirable to determine the type of lyrics to be acquired in the restriction mode at each stage according to the data amount of each lyrics. In particular, karaoke lyrics data including text information of lyrics and timing information is considered to have a large amount of data. Therefore, it is more effective to reduce power consumption if it is not included in the type of lyrics requested for acquisition.

  Further, the number of types of lyrics requested for acquisition may be varied according to the contents of the conditions set in the restriction mode. For example, in the restricted mode due to the illumination of the display 21 being OFF, three types of lyrics are requested to be obtained, and in the restricted mode due to the power saving mode being set, two types of lyrics are requested to be obtained. However, when the remaining amount of the battery power supply 28 is 30% or less, it may be varied according to the conditions set in the restriction mode, such as requesting acquisition of one type of lyrics.

  In step S205, four types of lyric data, which are all types of lyric data, are acquired. However, the lyric management server 50 does not store four types of lyric data depending on the tune and does not store three types or less. There is a case that only memorize. The lyrics management server 50 manages information indicating whether or not each type of lyric data exists for each piece of music together with the lyric data, and there is no lyric data for that type of lyric data that is not stored. Information indicating this may be transmitted to the display device 20.

  In addition, the display device 20 can designate a music for displaying lyrics as well as the music to be reproduced. When designating a song for which lyrics are to be displayed, for example, the artist name or the song name is used as a search keyword, and the lyrics of the song to be browsed are searched and designated using the display 21. When the music to be displayed is designated without reproducing the music, in step S201 of the lyrics acquisition process shown in FIG. 6, it is not determined whether or not the continuous reproduction mode is selected. When either S203 or step S204 is determined as YES, the type of lyrics data set to be displayed may be acquired.

  In the present embodiment, in step S207, when the restriction mode is set, the lyrics of the acquired music are the same type of lyrics as the type of the lyrics of the music that was played before the music that was designated for playback. There is but is not limited to this. The number of times of browsing the lyrics browsed in the past may be tabulated for each type, and the type of lyrics information having the largest number of times of browsing may be acquired.

  In this embodiment, in step S209, when the display device 20 is in the restriction mode, the type of lyrics data determined to be acquired is changed to “normal lyrics”, but the type of lyrics data requested to be acquired is , Not limited to "normal lyrics". The lyrics data with the lyrics data type “Lyrics with Japanese translation” is information that displays the Japanese translation of the lyrics of the song, so it is possible that the amount of data is as small as the lyrics data of “Normal lyrics” . Therefore, the type of lyric data requested to be acquired that is changed in step S209 may be “Japanese lyrics”.

  In this embodiment, when it is determined that the restriction mode is set, the type of lyrics requested to be acquired is limited, and only one specific type of lyrics can be acquired. However, the user may want to acquire a desired type of unacquired lyrics even when the display device 20 is in the restricted mode. When the display device 20 is in the restricted mode, the user designates a desired type of lyrics, so that an acquisition request for that type of lyrics is made, and in addition to a specific type of lyrics, the designated type of lyrics It may be configured to be able to acquire.
