[Prior art]
2. Description of the Related Art Conventionally, there are many audio devices using recording media such as audio tapes, CDs, and MDs. However, the development of data compression technology such as MPEG3 (Moving Picture Experts Group Audio Layer-3), memory cards and ultra-compact Due to the increase in recording density and miniaturization of storage devices found in hard disks and the like, a large amount of music can be stored and listened to even in portable information terminal devices such as mobile phones.
[0003]
In a conventional apparatus having a small storage capacity, the number of music pieces that can be stored is small, and thus the order of music pieces to be reproduced is performed in the order of storage, random, or by manual rearrangement. However, some recent memory cards have capacities approaching the gigabyte unit, and the same applies to ultra-small hard disks. Therefore, it is possible to store tens to hundreds of music pieces.
[0004]
Patent Literature 1 discloses a method of recording recently reproduced music or frequently reproduced music by separately recording, on an optical card, reproduction information of a music stored in a relatively large-capacity recording medium such as an LD (Laser Disk). The selected songs are displayed in order so that the user can easily select a particular song.
[0005]

[Problems to be solved by the invention]
However, with the development of technology, when a large number of songs are stored in a recording medium or a storage medium, it is difficult to listen to a plurality of songs in order according to a user's preference in order by a conventional reproducing method based on a song order. It becomes difficult. Also, considering the number of songs, it is practically difficult to manually rearrange the songs in a more enjoyable order.
[0007]
When music is recorded on a recording medium having a relatively large recording capacity, such as an LD, disclosed in Patent Document 1, data is stored on an optical card because another optical card is used to store reproduction information of the music. A structure for recording and reproducing is required, which leads to an increase in the price of the device, and in the case of a portable device, it is a factor that hinders downsizing of the device. Furthermore, if information on songs recorded on an optical card is used, the user can easily select songs, but it is difficult to select a plurality of songs that are preferred or frequently listened to. It is very inconvenient to select.
[0008]
In addition, in the reproducing method according to the related art and Patent Document 1, when it is desired to listen to a desired portion of each of a plurality of songs that are frequently listened to, it cannot be realized without performing a fast-forward or stop operation each time the songs are reproduced. Is difficult in practice.
[0009]
The present invention has been made in view of the above circumstances, and has a partial playback function of storing and playing back an arbitrary portion for each song from many songs stored in a storage medium in accordance with a user's taste and preference. Information terminal device having a function of automatically generating / updating a song order list according to the user's preference by using a playback history at the time of song playback, and playing back the song in the song order. The purpose is to provide.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides an information terminal device that includes a storage medium that stores music data for each song, and reproduces songs that are selected in the order in which the songs are stored or one song at a time. Partial playback time setting means for arbitrarily setting the playback start time and playback end time for each song and registering it in the partial playback time list, and for each song, the number of times played and the latest date and time played A data list generating / updating unit for automatically generating and updating a data list to be recorded; a user list creating unit for manually rearranging the songs stored in the storage medium; and a music list based on the data recorded in the data list. A music order list generating means for automatically rearranging the music data in a reproduction order according to a predetermined rule to generate a music order list; and recording music data stored in the storage medium in an order described in the user list and in a music order list. The order, or songs and a music reproducing means for reproducing in any order of the order in which they are stored.
[0011]
Further, the music order list automatically generated based on the data list includes a frequency list in which the music is recorded in descending order of the number of times of reproduction, and a history list in which the music is recorded in descending order of the reproduction date and time.
[0012]
The user list is a plurality of different user lists.
[0013]
Further, at the time of music data reproduction, a frequency list, a history list, and a user list can be alternatively selected, and when any of these lists is selected, the order of the songs described in the selected list is selected. If none of these lists is selected, the music data is reproduced in the order in which the songs were stored in the storage medium.
[0014]

[0024]
The storage area of the storage medium 7 in which the music data and the list generated or updated simultaneously with the storage of the music data as described above will be described with reference to FIG. FIG. 3 is a schematic diagram of the storage medium 7 showing an area where songs of N music data and their related lists are stored.
[0025]
The storage area of the storage medium 7 is divided into two parts: a music data area in which music data, that is, music data having titles of music 1 to music N is stored, and a list area in which related lists of music data are stored. Split. The description of the area where other information data is stored is omitted.
[0026]
The related list includes a music order list 20 including a history list 22 and a frequency list 23, an initial list 21, a user list 24, a partial playback time list 25, and a music data list 26. Stored in the area. By storing the music data and the related list in the same storage medium 7 in this way, the management of the music data for each removable storage medium 7 becomes possible independently, and another information terminal device having the same function If the storage medium 7 is attached to the storage medium 7, the music is reproduced as managed in the related list of the storage medium 7.
[0027]
Next, the details of these related lists and their roles will be described with reference to FIGS. 4A and 4B show the structure of a list indicating the order of songs at the time of reproduction. FIG. 4A shows an initial list 21, FIG. 4B shows a history list 22, FIG. 4C shows a frequency list 23, and FIG. 24 is shown.
[0028]
The initial list 21 describes individual songs having titles of music 1 to music N, respectively, in the order in which they are stored in the storage medium 7. In FIG. 4A, the music data is newly stored as the music order is smaller. That is, this is an example in which music 1 is stored first and music N is recently stored. When the music data stored in the storage medium 7 is reproduced, if the initial list 21 is selected by the user, the music data is reproduced in ascending order of music number.
[0029]
In the history list 22, when a song having a title of each of music 1 to music N is reproduced even once, the titles are rearranged such that the latest reproduction date and time have the smaller song order. In FIG. 4B, the music data reproduced more recently as the music order is smaller. When playing back the music data stored in the storage medium 7, if the history list 22 is selected by the user, the music data is played back in ascending order of music number.
[0030]
In the frequency list 23, when a song having a title of each of music 1 to music N is stored and played back one or more times, the titles are rearranged so that the one with the larger number of plays has the smaller song order. In FIG. 4C, the music data is reproduced more frequently as the music order is smaller. When the music data stored in the storage medium 7 is reproduced, if the frequency list 23 is selected by the user, the music data is reproduced in ascending order of the music number.
[0031]
The user list 24 is a list in which songs having titles of music 1 to music N are manually rearranged by the user via the operation input unit 3 and the display unit 4 (FIGS. 1 and 2) of the information terminal device 1. It is. In FIG. 4D, the smaller the music order is, the faster the music is to be reproduced.

By properly using a plurality of user lists, it is possible to listen to music stored in one storage medium 7 in an arbitrary order by grouping by genre, artist, or specific group.
[0032]
5A and 5B show an example of the partial playback time list 25. FIG. 5A shows an example of an initial state list, and FIG. 5B shows an example updated by the user. Normally, music data compressed by a data compression technique such as MPEG3 has a title and data reproduction time recorded along with the data. Each time new music data is stored in the information terminal device 1, the title and the reproduction time are read, and the reproduction time of the newly stored music is set in the partial reproduction list 25 as shown in FIG. 0:00, and the length of the reproduction time is recorded as the end time and stored.
[0033]
FIG. 6 is a flowchart showing a procedure when the user changes the partial playback time list 25. When the user enters the partial playback time change mode according to a predetermined operation procedure, the updating process of the partial playback time list is started. First, in S1 (step 1), a song to be changed is selected and reproduced. In S2, the user presses a predetermined key on the operation input unit 3 (FIGS. 1 and 2) when listening to the music and finds a place where partial reproduction is to be started. Then, in S3, the required time from the start of the music to the start is registered as the start time in the partial reproduction, and the data of the start time of the music is changed in the partial reproduction time list 25 of FIG. 5B. If the predetermined key is pressed again in S4 because the same music is continuously reproduced, the time required from the start of the music to the start is registered as the end time in the partial reproduction in S5, and FIG. The data of the end time of the music is changed in the partial playback time list 25). Thereafter, the reproduction of the music ends in S6.
If the predetermined key is not depressed at all in S2 or S4 and the reproduction of the music is completed in S6, the partial reproduction time of the music is not changed. Further, when the predetermined key is pressed once in S2 and the reproduction of the music ends in S6 without the second pressing, only the start time of the partial reproduction time is changed, and the end time is not changed.
[0035]
An example of the partial playback time list 25 updated from the initial state in this manner is as shown in FIG. As will be described later, when the user selects and plays back the initial list 21, the history list 22, the frequency list 23, or the user list 24, it is determined whether or not the playback is to be performed with reference to the partial playback time list 25. You can make a selection. For example, when the history list 22 shown in FIG. 4B is selected and the reproduction is performed with reference to the partial reproduction time list 25, for example, the history list 22 is displayed along the partial reproduction time shown in FIG. The written tune is reproduced from the tune having the smallest tune number. When the partial reproduction time list 25 is not referred to, the music data from the original start time to the end time is reproduced according to the history list 22.
[0036]
FIG. 7 is a diagram showing an example of the music data list 26. The song data list 26 includes a title, the number of times the song has been played since it was stored, and the latest playback date and time, and is updated each time a song is played. When a song is stored in the storage medium 7, the title of the song, the number of times of reproduction 0, and the stored date and time are set as initial values. The music data list 26 is a list from which the history list 22 and the frequency list 23 are updated.
[0037]
FIG. 8 is a flowchart showing a flow of updating the music data list 26, the history list 22, and the frequency list 23. When the reproduction of a certain music is completed in S11 (step 11), first, the music whose reproduction has been completed is selected from the music data list 26, and the number of times of reproduction and the reproduction date and time of the music are updated in S12. When the process is completed, in S13, the history list 22 is rearranged in the order of the reproduction date and time and updated with reference to the music data list. When the processing is completed, the music data list is again referred to in S14, and the frequency list 23 is rearranged in the descending order of the number of times of reproduction and updated.
[0038]
FIG. 9 shows a flowchart in the case where the music data stored in the storage medium 7 is reproduced by using the generated and updated lists. FIG. 9A shows a case where reproduction is performed irrespective of the partial reproduction time list 25, and FIG. 9B shows a case where reproduction is performed according to the partial reproduction time list 25. Prior to the reproduction of the music data, it is assumed that a selection has been made as to whether or not the reproduction is performed by applying the partial reproduction time list 25. When the application of the partial playback time list 25 is selected, the operation is performed as shown in the flowchart of FIG. 9 (b) is different from FIG. 9 (a) in the portions of S22b, S25b, S26b and S27b where the reproduction is performed in the order of the songs described in the respective lists, and this portion is reproduced in the order of the respective songs. Occasionally, the corresponding tune is reproduced according to the start time and the end time registered in the partial reproduction time list 25. Therefore, hereinafter, only FIG. 9A will be described, and description of FIG. 9B will be omitted.
[0039]
First, in S21 (step 21), whether to use the user list 24, the history list 22, or the frequency list 23 is selected. If not used, the process branches to S22a, and music is reproduced in the order described in the initial list 21. When the user list 24, the history list 22, or the frequency list 23 is used in S21, selection of which list is used is performed in S23. If the user list 24 is used, the process proceeds to S24. If there are a plurality of user lists, one is selected, and in S25a, the music data is reproduced according to the selected user list. When the history list 22 is selected in S23, the music data is reproduced in the order described in the history list 22 in S26a. When the frequency list 23 is selected in S23, the music data is reproduced in the order described in the frequency list 23 in S27a.
[0040]
The song order list 20, the initial list 21, the user list 24, the partial playback time list 25, and the song data list 26 including the history list 22 and the frequency list 23 are not shown and described, but each have a predetermined file name. And saved. When two or more user lists can be used, a different file name or a different identifier is added to each user list and stored.
[0041]
