Description

  The present invention relates to an information processing apparatus and method, a program, and a recording medium, and more particularly, to an information processing apparatus and method, a program, and a recording medium that make it easy to select a favorite song.

  It is very difficult to select a song that suits one's preference from a myriad of songs.

  Request programs such as radio broadcasts are used as a method for efficiently selecting favorite music. That is, the requested program broadcasts music according to the number of requests of many users (people who listen to music). For this reason, the user can know the songs supported by many people from the recently released songs by listening to this request program and the songs broadcast according to the number of requests by others. You can select your favorite music with reference to the music.

  However, when using the requested program to select a favorite song, requests from many users are necessary, and there is a problem that it places a burden on many users. .

  In addition, since the requested program is broadcast, for example, even if the user does not like the music being distributed, it must be listened to the end, and it is impossible to stop listening to music that he does not like on the way.

  Furthermore, since the request program needs to be broadcast within a limited time, the number of songs that can be broadcast is limited, and the number of songs that can be listened to in the request program is a predetermined number (1 hour request program). In this case, the requested music is about 20 music).

  In addition, a method of pre-registering personal favorite genres and distributing music according to the preference, and a method of estimating and distributing favorite music based on past history (song selection, playback history) have also been proposed. However, when registering a preference, it is necessary to input the favorite genre itself, which imposes a burden on the user and only the range of the genre specified by the user is selected. There is a problem that it becomes difficult to select a favorite song from other than the above. Furthermore, when the past history is used, music selection depending on the past history is made, and thus there is a problem that it becomes difficult to select a favorite music in a new genre. In addition, since a dedicated server is required to register preferences and past histories, there has been a problem that the cost for maintenance and management of the server becomes large.

  The present invention has been made in view of such a situation, and allows the user to efficiently select a favorite song without being limited to a specific genre, and can select a favorite song without using a server. It makes it possible to select songs.

Therefore, the following functional block diagram may be viewed as a hardware configuration diagram or a software configuration diagram.

  The control unit 71 controls the overall operation of the mobile terminal 11. The recommended music list storage unit 72 stores a recommended music list. The recommended song list is a song stored in the owned song list storage unit 74 or a song stored in the collected song list storage unit 75 when the operation unit 78 is operated by the user and reproduced by the reproduction unit 77. The recommended music list generation unit 73 detects the operation state, and is generated according to the operation state. More specifically, when the played music is played for a predetermined time or more, or when it is designated as a recommended music by the user (for example, when it is selected as “favorite” described later), it is for the user. Assuming that the music is preferred, it is recorded in the recommended music list and stored in the recommended music list storage unit 72.

  The recommended song list generation unit 73 generates the recommended song list as described above and stores it in the recommended song list storage unit 72. Since the songs described in the recommended song list are distributed, the copyright is reserved. In consideration, only a part of the music data is recorded, or the music data is recorded at a low bit rate. Further, the recommended music list generation unit 73 compresses music data in a predetermined compression format (for example, MP3 (Moving Picture Experts Group 1 Layer 3), etc.) in order to reduce the communication load of the communication unit 76. Further, the recommended song list generation unit 73 compares the recommended song list transmitted from the other portable terminal 11 with its own collected song list, and among the recommended song lists transmitted from the other portable terminal 11. , Only songs that are not listed in the collected song list are listed in the collected song list, stored in the collected song list storage unit 75, and recommended if they are listed in the collected song list A recommender counter indicating the number of users of the mobile terminal 11 is incremented by one. By repeating such a process, information indicating which music is supported by many people will be stored, so the user himself / herself by looking at the collected music list It can be used as a reference for selecting a favorite song.

  The owned music list storage unit 74 stores an owned music list currently stored in the mobile terminal 11. As shown in FIG. 4, the owned music list includes music broadcasted (by radio and television) and recording media purchased by the user (for example, CD: Compact Disc and MD: Mini Disc (registered trademark)). Or EMD (Electrical Music Distribution: data related to a song (for example, song name, playback restriction, etc.) via a network such as the Internet (not shown) in response to a request from the mobile terminal 11 ) And music data are supplied.) Each artist name, music title, playback time, music data, and the like of music distributed from a server or the like are stored.

  The collected music list storage unit 75 stores a list of music listed in the recommended music list in the other portable terminal 11 including its recommended music list.

  The communication unit 76 is a program for controlling the communication unit 39 of FIG. 2 and stores its own ID 76a. First, a search signal for searching for the presence of another mobile terminal 11 in the vicinity is transmitted in the wireless channel system. Send by communication. In response to the search signal, the presence / absence of an ID for identifying the mobile terminal 11 transmitted from another mobile terminal 11 is detected, and when the ID is detected, its own ID 76a is transmitted based on the detected ID. Establish communication. This communication is short-range communication between the mobile terminals 11 and is, for example, Bluetooth. Further, when communication is established, the communication unit 76 transmits its own recommended song list, requests exchange with the recommended song list generated by the other portable terminal 11, and transmits from the other portable terminal 11. The received recommended music list is received and output to the recommended music list 73. That is, the ID 76a here is, for example, an IP (Internet Protocol) address referred to on the Internet.

  The reproduction unit 77 is controlled by the control unit 71 and reproduces various pieces of music data. At this time, if the music data is compressed by a predetermined compression method, it is reproduced with appropriate expansion processing.

  The operation unit 78 is used for operation contents such as when the user selects a song, when the selected song is played, stopped, or when another song is selected, or when a song is selected as a favorite. The corresponding information is output to the control unit 71. Note that selection to a favorite here means that, for example, a button for selecting a favorite is set and the button is pressed to select the favorite. The music selected as a favorite is usually the user's favorite music, so for example, music that can be selected and played (easily played) by operating a predetermined button separately from other music, for example. Indicates that it will be selected.

  Next, the details of the owned music list will be described with reference to FIG.

  The possessed music list is a list indicating information on the music owned by the mobile terminal 11 itself. As shown in FIG. 5, recommendation information (described as “recommendation” in the figure), artist name, playback time, and music data (for example, a file name including music data) are described from the left. In the example of FIG. 5, “song b” and “song c” are described from the top as song names, and “BB” and “CC” are listed as artist names from above, Are described as “2:45” and “3:50” from the top, and in the music data, “b.WAVE” and “c.WAVE” are described. The artist is BB and the playback time is 2 minutes 45 seconds; b. What is contained in the WAVE file called WAVE is that the song c is the artist CC and the playback time is 3 minutes 50 seconds, c. Each is shown to be contained in a WAVE file called WAVE.

  The recommended information is, for example, when the played music is played for a predetermined time or more, or when the user designates it as a recommended music (for example, when “Favorite” is selected). For example, when the music b is selected as the recommended music, it is assumed that the music is regarded as liking. For example, when the music b is selected as the recommended music, “O” is displayed in the field as shown in FIG. Is described. And the recommended music list production | generation part 73 produces | generates a recommended music list as shown in FIG. 7 based on this recommendation information. That is, the recommended song list is composed of information on the song name, artist name, playback time, and song data, in the same manner as the owned song list. When the recommended song list is generated, the song data is attached at the same time, but the song data is compressed. In FIG. 7, the music data is described as “b.MP3”, and the WAVE format file described as “b.WAVE” is compressed by the MP3 method.

  Next, the recommended song list generation process will be described with reference to the flowchart of FIG. In step S <b> 1, the control unit 71 determines whether or not the operation unit 78 is operated by the user and the reproduction target music is selected in the owned music list, and it is determined that the music to be reproduced is selected. The process is repeated until For example, if it is determined that the song b is selected as the reproduction target song in the owned song list shown in FIG. 5, the control unit 71 uses the song data of the song b included in the owned song list in step S <b> 2. A file “b.WAVE” is read out and supplied to the playback unit 77 for playback.

  In step S <b> 3, the control unit 71 determines whether or not the operation unit 78 is operated by the user to be stopped, the music is not changed, and the reproduction is continued. For example, when it is determined that the reproduction is continued as it is, the process proceeds to step S4.

  In step S4, the control unit 71 determines whether or not the reproduction is continued for a predetermined time. If it is determined that the reproduction is not continued, the process proceeds to step S5.

  In step S <b> 5, the control unit 71 determines whether the user has added the currently selected music piece to the favorites by operating the operation unit 78. For example, if it is determined that the item has not been selected as a favorite, the process returns to step S3. That is, if the reproduction state continues and the state where it is not selected as a favorite continues, the processes of steps S3 to S5 are repeated.

  If it is determined in step S4 that the reproduction is continued for a predetermined time, or if a predetermined favorite button is operated in step S5 and it is determined that the currently selected music is selected as a favorite, In step S6, the recommended song list generation unit 73 writes “◯” indicating that it is a recommended song in the recommendation information column of the owned song list of the owned song list storage unit 74, as shown in FIG. Select as recommended music.

  In step S <b> 7, the control unit 71 determines whether or not other music is also instructed to be played back continuously. For example, if it is determined that playback of other music is also selected, In S <b> 8, other songs are read from the owned song list storage unit 74 and output to the playback unit 77. In this case, since the music piece c is selected from the owned music list, the file “c.WAVE” is read, and the processes in and after step S2 are repeated.

  If it is determined in step S7 that playback of another song is not instructed, in step S9, the recommended song list generation unit 73 determines whether there is a recommended song with reference to the owned song list. . In this case, since the music b is selected as the recommended music, the process proceeds to step S10, and the recommended music list generation unit 73 reduces the bit rate of the music data of the selected music b, Alternatively, after converting a piece of the song into a format that has no copyright problem, and converting it into a MP3 format from the WAVE file, the recommended song list as shown in FIG. Is updated (if the recommended music list does not exist, a recommended music list is generated) and stored in the recommended music list storage unit 72.

  If it is determined in step S3 that the reproduction is not continued, the processes in steps S4 to S6 are skipped.

  If it is determined in step S9 that no recommended music exists, the process in step S10 is skipped and the recommended music list is not updated.

  Through the processing as described above, the user simply performs an operation such as playback, stop, or change of music, and the recommended music list is sequentially generated without the user being aware of it. In the above example, the case has been described where it is registered in the recommended song list when it is played for a predetermined time or when it is selected as a favorite. For example, when a predetermined part is played, May be selected in the recommended music list when it is played from the end to the end, or when it is played back after rewinding. In addition, the recommended music list may include information on the reproduction time and information on the number of reproductions.

  Next, a process of generating a collected music list by exchanging (receiving and receiving) the recommended music list generated by the above process between the mobile terminals 11 will be described.

  For example, the recommended music list exchange process between the mobile terminals 11 starts communication with each other when the mobile terminals 11 can communicate with each other as shown in FIG. The lists are exchanged, and a collected music list is generated based on each recommended music list. In FIG. 9, an area 91-1 indicates a range in which the mobile terminal 11-1 can communicate, and an area 91-2 indicates a range in which the mobile terminal 11-2 can communicate.

  That is, when this state is reached, each portable terminal 11-2 recognizes the existence of the other party and starts communication. For example, the portable terminal 11-1 transmits the recommended song list shown in FIG. 7 to the portable terminal 11-2, and the portable terminal 11-2 sends the recommended song list as shown in FIG. 10 to the portable terminal 11-1. In such a case, the portable terminals 11-1 and 11-2 mutually generate a collected music list as shown in FIG.

  That is, in the recommended song list transmitted from the portable terminal 11-2 to the portable terminal 11-1, as shown in FIG. 10, "Song a" and "Song d" are described as the song names from the top, and the artist “AA” and “DD” are described in the names, “5:10” and “4:55” are described in the playback time, and “a.MP3” is included in the music data. , “D.MP3” are described, music a and d are selected as recommended music, the artist names of the music are “AA” and “DD”, and the playback time is 5 minutes 10 minutes. 2 seconds and 4 minutes and 55 seconds, and it is shown that each piece of music data is stored in files a.MP3 and d.MP3.

  By exchanging the recommended song list, the collected song list possessed by the portable terminals 11 is a combination of the recommended song list of FIG. 7 and the recommended song list of FIG. 10, as shown in FIG. Furthermore, a recommendation information column is provided for each song, and it is possible to generate a recommended song list again in each of the mobile terminals 11-1 and 11-2. In addition, a counter for the number of recommenders is provided for each song, and among the songs described in the recommended song list received from the other mobile terminal 11, the same song described in its recommended song list Is present, the counter indicating the number of recommenders of the music is incremented by one. In the case of FIG. 11, the number of recommenders for music a to music c is all 1.

  Next, the collected music list generation process by the portable terminal 11-1 and the portable terminal 11-2 will be described with reference to the flowchart of FIG.

  In step S21, the control unit 71 of the mobile terminal 11-1 controls the communication unit 76 to transmit a search signal, and in step S22, the ID 76a-1 (in the following description, the mobile terminal 11-1 It is determined whether or not there is a mobile terminal 11-2 that transmits the ID (referred to as 76a-1 and the ID of the mobile terminal 11-2 as 76a-2).

  Here, in step S41, the communication unit 76 of the mobile terminal 11-2 determines whether or not a search signal is detected, and repeats the process until the search is performed. For example, when a search signal is transmitted by the process of step S41, the communication unit 76 of the mobile terminal 11-2 reads out its own ID 76a-2 and transmits it via a wireless line in step S42, and further, step S43. In step S41, it is determined whether or not there is a connection request, and the processes in steps S41 to S43 are repeated until it is determined that there is a connection request.

  In step S22, for example, when the ID 76a-1 is transmitted from the communication unit 76 of the portable terminal 11-2 by the process of step S42, the control unit 71 of the portable terminal 11-1 transmits the mobile phone that transmits ID 76a-2. It is determined that the terminal 11-2 exists, and the process proceeds to step S23.

  In step S23, the control unit 71 of the mobile terminal 11-1 controls the communication unit 76 to transmit its own ID 76a-1 based on the detected ID 76a-2 of the mobile terminal 11-2 and request connection. .

  Here, in step S43, the communication unit 76 of the mobile terminal 11-2 determines that there is a connection request from the mobile terminal 11-1, and is transmitted from the communication unit 76 of the mobile terminal 11-1 in step S44. Communication is established based on the ID 76a-1.

  In step S24, the communication unit 76 of the portable terminal 11-1 establishes communication with the communication unit 76 of the portable terminal 11-2 by the process of the portable terminal 11-2 of step S44.

  In step S25, the control unit 71 of the mobile terminal 11-1 controls the communication unit 76 to transmit the recommended music list and to transmit the recommended music list of the mobile terminal 11-2. To request.

  In step S45, the control unit 71 of the portable terminal 11-2 controls the communication unit 76 to determine whether or not the recommended song list is requested from the portable terminal 11-1, and the recommended song list is requested ( At this time, the processing is repeated until the recommended music list of the portable terminal 11-1 is transmitted at the same time. For example, when the recommended song list is requested from the portable terminal 11-1 through the process of step S25, it is determined that the recommended song list is requested. In step S46, the control unit 71 of the portable terminal 11-2 While receiving the recommended song list of the terminal 11-1, it reads out its recommended song list stored in the recommended song list storage unit 72 and outputs the communication unit 76. Furthermore, in step S47, the communication unit 76 of the mobile terminal 11-2 transmits the read recommended song list of the mobile terminal 11-2 to the mobile terminal 11-1, and ends the communication in step S48.

  In step S26, the control unit 71 of the mobile terminal 11-1 controls the communication unit 76 to receive the recommended song list of the mobile terminal 11-2 transmitted by the process of step S47, and causes the advertisement storage unit 102 to receive the recommended music list. At the same time, in step S27, corresponding to the processing in step S48, the communication unit 76 is controlled to end communication with the portable terminal 11-2.

  In step 28, the recommended song list generation unit 73 of the portable terminal 11-1 compares the received recommended song list of the portable terminal 11-2 with the collected song list stored in its own collected song list storage unit 75, Extract music that does not exist in your own music collection list and list it in your own music collection list. For music that exists in your own music collection list, increment the counter for the number of recommenders by 1 (new collection) When added to the music list, 1 is entered as an initial value). A collected music list is generated and stored in the collected music list storage unit 75. However, in the case of the first processing, since the collected music list of the portable terminal 11-1 does not exist, after creating the collected music list by copying the owned music list (at this time, the music data is stored in a predetermined compression method). After being compressed (in this case, compressed from a WAVE file to an MP3 file), the received music is compared with the recommended music list of the mobile terminal 11-2.

  In step S29, the control unit 71 of the portable terminal 11-1 reads out the collected music list stored in the collected music list storage unit 75 and displays the collected music list on a display, for example. In step S30, the control unit 71 determines whether or not a predetermined time has elapsed, repeats the process until the predetermined time has elapsed, and determines that the predetermined time has elapsed, Return to S21. That is, the processes in steps S21 to S30 are repeated at predetermined time intervals.

  In this case, as shown in FIG. 7, only the music b is listed in the recommended music list of the mobile terminal 11-1, but the recommended music list received from the mobile terminal 11-2 includes the music a, d. As a result, as shown in FIG. 11, a music collection music list in which music a, b, and d are described is generated, and the number of recommenders is described as 1 for each.

  On the other hand, in step S49, similar to the process of step S28, the recommended song list generation unit 73 of the mobile terminal 11-2 stores the received recommended song list of the mobile terminal 11-1 and its collected song list storage unit 75. Compared to the stored song list stored, extract songs that do not exist in your own song list, list them in your own song list, and select the number of recommenders for songs that exist in your own song list. The counter is incremented by 1 (when newly added to the collected music list, 1 is entered as an initial value), a collected music list is generated and stored in the collected music list storage unit 75.

  In step S50, the control unit 71 of the portable terminal 11-2 reads the collected music list stored in the collected music list storage unit 75 and displays it on, for example, a display, and the process returns to step S41.

  In this case, as shown in FIG. 10, the songs a and d are listed in the recommended song list of the portable terminal 11-2, but the song b is included in the recommended song list received from the portable terminal 11-1. As a result, as shown in FIG. 11, a music collection music list in which music a, b, and d are described is generated, and the number of recommenders is described as 1 for each. In this display, for example, the recommended music pieces may be sorted and displayed based on the number of reproductions, reproduction time, or reproduction time.

  Note that the processing of the left and right flowcharts in FIG. 12 is processing that is executed in any one mobile terminal 11, and in the flowchart of FIG. 12, the processing on the left side is repeatedly executed at predetermined time intervals. The process of the flowchart of FIG. 12 is a process that is started when a search signal is received. The process on the left side of FIG. 12 may be started by the user's intention by the user of the mobile terminal 11 operating the operation unit 78, for example.

  Therefore, for example, as shown in FIG. 13, when the mobile terminals 11-11 to 11-15 exist in an area 91 that is a communicable range of the mobile terminal 11-11, 11-11 is the music b as the recommended music list, the mobile terminal 11-12 is the music a, d as the recommended music list, the mobile terminal 11-13 is the music f, g as the recommended music list, and the mobile terminal 11-14 is When the music a, e, f and the mobile terminal 11-15 as the recommended music list and the music a and b as the recommended music list are stored in the respective recommended music list storage units 72, the collection of the mobile terminals 11-11 The music list is as shown in FIG. In FIG. 13, only the music titles in the recommended music list are displayed. In FIG. 14, only the song name and the number of recommenders in the collected song list are displayed, and the artist name, playback time, and song data display are omitted.

  In other words, since the mobile terminal 11-11 stores information on the recommended music list of the mobile terminals 11-11 to 11-15, the mobile terminal 11-12, 11-14 is used for the music a. The number of recommenders is 2 because the music is recommended by the user, the number of recommenders is 2 for the music b, and the number of recommenders is 2 because the music is recommended by the user of the mobile terminal 11-15. The number of recommenders is 1 because the music is recommended by the user of -12, the number of recommenders is 1 because the music e is the music recommended by the user of the mobile terminal 11-14, and the number of recommenders is 1 Since it is the recommended music of the user of the terminals 11-13 and 11-14, the number of recommenders is 2.

  The user of the portable terminal 11-11 recommends the music a among the users who are close to the user (a position where communication is possible with the communication unit 76) by looking at the collected music list as shown in FIG. It is recognized that there are the most users and then there are many users who recommend the music pieces b and f.

  Based on this information, the user generates a recommended song list again by listening to the songs in the collected song list.

  Here, with reference to the flowchart of FIG. 15, a process of generating a recommended song list from songs in the collected song list will be described. In the flowchart of FIG. 15, the processing of steps S72 to S80 is the same as the processing of steps S2 to S10 in the flowchart of FIG.

  In other words, in step S71, the control unit 71 determines whether or not the operation unit 78 is operated by the user and the reproduction target music is selected in the collected music list, and the reproduction target music is selected. The process is repeated until it is determined. For example, if it is determined that the music piece a is selected as a reproduction target music piece from the collected music list shown in FIG. 14, the process proceeds to step S72, the corresponding music piece a is reproduced, and the subsequent processing proceeds. .

  For example, if it is determined in step S74 that the music pieces a, b, and e have been reproduced for a predetermined time or added to favorites, the process of step S76 causes the collected music pieces to be collected as shown in FIG. “○” is described in the recommended information of the list, and the recommended music list as shown in FIG. 17 is generated in the process of step S80 (in FIG. 17, the music name in the recommended music list is shown). Only is listed). Then, by newly executing the process of the flowchart of FIG. 12 using this recommended song list, it is possible to repeat the exchange of the recommended song list with another portable terminal 11.

  Also, for example, as shown in FIG. 18, when mobile terminals 11-22 to 11-24 exist in an area 91-1, which is a communicable range of the mobile terminal 11-21, first, these mobile terminals 11- The processing of the flowchart shown in FIG. 12 is executed between 22 and 11-24. By this processing, as shown in FIG. 19, the portable terminal 11-21 is in a state where the recommended music list has been exchanged with the portable terminals 11-22 to 11-24. However, in this state, the collected music list to be generated is merely a reference of the recommended music list of the user for a total of four people, and the number of recommenders is small to select a favorite music with reference. . Therefore, as illustrated in FIG. 20, areas 91-2 and 91-3 that are communicable ranges with the mobile terminals 11-22 and 11-23 that exist in the area 91-1 that is the communicable range of the mobile terminal 11-21. By communicating with the mobile terminals 11-31 and 11-32 existing in each of the mobile terminals via the mobile terminals 11-22 and 11-23, the recommended music list can be exchanged with many users. You may do it.

  However, in this case, if communication is not restricted between the mobile terminals 11, communication continues indefinitely. Therefore, it is necessary to limit the communication range by limiting the number of hops. Here, the number of hops indicates the number of mobile terminals 11 interposed between the mobile terminals 11 exchanging recommended music data. For example, as shown in FIG. 20, the mobile terminals 11-21 are mobile terminals 11. When the advertisement data is acquired from −22, the number of hops is 0 because communication is performed directly. When the mobile terminal 11-21 communicates with the communication terminal 11-32, the number of hops is 1 because one mobile terminal 11-22 is interposed.

  FIG. 21 shows a configuration of the portable terminal 11 that can communicate with each other when communicating between the portable terminals 11.

  In FIG. 21, portions corresponding to those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted as appropriate. The portable terminal 11 in FIG. 21 is different from the portable terminal 11 in FIG. 3 in that a transfer unit 91 is newly provided. The basic function of the transfer unit 91 is the same as that of the communication unit 105, but the ID 91a is used when transferring. That is, for example, when the mobile terminal 11-11 communicates with the mobile terminal 11-32 via the mobile terminal 11-22, the transfer unit 91 of the mobile terminal 11-22 functions as a relay device, and all of the information to be transferred Is transmitted with its own ID 91a. For this reason, the communication-destination mobile terminal 11 can recognize its own hop count from the number of IDs 91a of the transfer unit 91 of the mobile terminal 11 existing as a relay included in the transferred information. . That is, when the mobile terminal 11-11 communicates with the mobile terminal 11-32, the mobile terminal 11-32 always receives information transferred from the communication unit 76 of the mobile terminal 11-11 to the mobile terminal 11-22. Therefore, the portable terminal 11-32 can recognize the number of hops by the number of IDs (in this case, the number of IDs 91a of the repeater is Since it is one, it can be recognized that the number of hops is one).

  Next, referring to the flowcharts of FIGS. 22 and 23, using the mobile terminal 11 of FIG. 21, the mobile terminal 11-11 of FIG. The process of exchanging and generating the collected music list will be described. In the description of the flowcharts of FIGS. 22 and 23, the processing of steps S103 to S111 and the processing of steps S137 to S145 are the same as the processing of steps S22 to S30 and the processing of steps S42 to S50 in the flowchart of FIG. Since it is the same as the process, the description of the process is omitted.

  In step S101, the control unit 71 of the portable terminal 11-11 initializes a built-in counter n to zero. In step S102, the control unit 71 of the mobile terminal 11-1 controls the communication unit 76 to transmit a search signal to the mobile terminal 11 having the number of hops n as viewed from its own position. In step S103, the ID 76a- 11 (in the following description, the ID of the mobile terminal 11-11 is referred to as 76a-11 and the ID of the mobile terminal 11-22 is referred to as 76a-22). It is determined whether or not.

  Here, in step S41, for example, the communication unit 76 of the mobile terminal 11-22 with the hop number 0 determines whether or not the search signal with the hop number n is detected, and repeats the process until the search is performed. For example, when a search signal with the number of hops n is transmitted in the process of step S102, the communication unit 76 of the mobile terminal 11-22 determines whether or not the search signal is for the number of hops of the mobile terminal 11-22 in step S132. Determine. For example, in the first process, since the number of hops n = 0, the number of hops is the number of hops. Therefore, the process proceeds to step S137, and the subsequent processes are repeated.

  And in step S112, the control part 71 of the portable terminal 11-1 determines whether it communicated with all the portable terminals 11 of the hop number n. For example, in the case of FIG. 20, when communicating with all the mobile terminals 11-22 to 11-24, the counter n is incremented by 1 (in this case, the counter n is 1). Furthermore, in step S113, the control unit 71 of the mobile terminal 11-1 determines whether or not the number is larger than a preset hop number N (N is preset), for example, from the set hop number N. If it is determined that it is not larger, the process returns to step S102.

  At this time, in step S102, a search signal with the number of hops n = 1 is transmitted. In this case, in step S132, since the portable terminal 11-22 is not the number of hops of the mobile terminal 11-22, the transfer unit 91 attaches its own ID 91a, and the search signal with the hop number of 1 is within the communicable range. Transfer in area 91-2. In the case of FIG. 20, the portable terminal 11-32 executes the processes of steps S131, S132, S137 to S145 for the transferred search signal.

  Meanwhile, in the portable terminal 11-22, in step S134, the control unit 76 determines whether or not there is a response. Here, since there is a response from the portable terminal 11-32, communication as a repeater is established in step S135. In step S136, it is determined whether or not the communication is completed. The process of S136 is repeated. In other words, in this state, the mobile terminal 11-22 functions as a relay device between the measuring terminal 11-11 and the mobile terminal 11-32, and attaches its own ID 91a to all relayed information.

  In step S136, when the communication between the portable terminal 11-11 and the portable terminal 11-32 ends, it is determined that the communication is ended, and the process returns to step S131.

  The same processing is performed between the portable terminal 11-31 and the portable terminal 11-23. If it is determined in step S112 that communication has been performed with all the mobile terminals 11 having the hop number 1, a search signal having the hop number 2 is transmitted in step S102. At this time, the portable terminals 11-22 and 11-23 proceed to the processes of steps S131 to S134, and similarly, the portable terminals 11-31 and 11-31 perform the processes of steps S131 to S134. In the case of FIG. 20, since there is no portable terminal 11 having the number of hops n = 2 or more, there is no response, so any one of the portable terminals 11-22, 11-23, 11-31, and 11-32. In step S131, the process returns to step S131.

  If it is determined in step S114 that the number of hops n is greater than the predetermined number of hops N, the process returns to step S101, and the subsequent processes are repeated. That is, the number of hops is small, that is, the number of hops gradually increases from the portable terminal 11 in a range close to the own portable terminal 11-11, that is, the position gradually moves away from the own portable terminal 11-11. Communication with the portable terminal 11 can be performed, and further, the communicable range can be limited by N that presets the hop number n.

  In the above, the case of sequentially accessing from the mobile terminal 11-11 in ascending order of the number of hops has been described. For example, as indicated by the arrow in FIG. 24, the area that is the communicable range of the mobile terminal 11-11 When a new portable terminal 11-41 enters 91-1, the state may be detected and new communication for exchanging the recommended music list may be started.

  According to the above, since it is possible to efficiently select a favorite music piece without using a server, it is possible to reduce costs and prevent concentration of access to the server. Moreover, since the favorite music is selected based on the recommended music of other users, the favorite music can be selected without being restricted by the favorite genre so far. Furthermore, since the music is selected based on the music recommended by another user, it becomes possible to select a favorite music from music having a certain amount of content (cleared evaluation by other users). Therefore, it is possible to reduce the burden on the user in the action of selecting a favorite music piece. Moreover, since the music which the user of each portable terminal is actually listening is recommended, the music which is popular recently can be understood in real time. Furthermore, it becomes possible to select a favorite music piece from among music pieces according to local conditions (location, time, weather, etc.). That is, for example, if a specific artist's live is in the vicinity, the number of users who recommend a lot of the artist's music increases in that area, so your favorite music is based on recommended music from users with similar preferences Can be selected.

  The series of processes described above can be executed by hardware, but can also be executed by software. When a series of processes is executed by software, a program constituting the software may execute various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed from a recording medium in a general-purpose personal computer or the like.

  As shown in FIG. 2, this recording medium is provided to the user in a state of being pre-installed in the mobile terminal 11, and provides the program to the user separately from the computer as well as the storage unit 38 in which the program is recorded. To be distributed, a magnetic disk 51 (including a flexible disk) on which a program is recorded, an optical disk 52 (including a compact disk-read only memory (CD-ROM), a DVD (digital versatile disk)), and magneto-optical It is composed of a package medium including a disk 53 (including MD (Mini-Disc) (registered trademark)) or a semiconductor memory 54 (including Memory Stick).

  In this specification, the step of describing the program recorded on the recording medium is not limited to the processing performed in time series in the order described, but of course, it is not necessarily performed in time series. Or the process performed separately is included.

  Further, in this specification, the system represents the entire apparatus constituted by a plurality of apparatuses.
