A method is conceivable.

The control processing executed by the music evaluation apparatus configured as described above will be described first with reference to FIG. 4 and then in detail with reference to FIGS.

In the client PC 0, network browser software (hereinafter referred to as “browser”) is started, and a URL (unun) on the network is transmitted from the browser.
iform resource locator), the URL
Is displayed on the browser. In this embodiment, one of two types of files, that is, (1) a comparative evaluation page and (2) a detailed evaluation page is displayed, and the user operates a switch on the displayed evaluation page, The music composition can be evaluated according to the evaluation method of each evaluation page.

FIG. 4 is a diagram showing an example of the (1) comparative evaluation page displayed on the browser.

As shown in the figure, (1) the comparative evaluation page is configured so that the following functions can be performed. That is, (a) the function of reproducing the performance of the music to be compared; (b) the voting function of voting on the music of the user who prefers;
VIEW ROOM ").

That is, the server computer 102
Two songs are randomly selected from a plurality of songs (in the present embodiment, 20 songs as described above) recorded in the presented song information, and are respectively associated with entry artists A and B, and a file of a comparative evaluation page is created. Create Then, using the created file, the evaluator displays a comparative evaluation page on the browser activated on the client PC0, and moves the PLAY switches corresponding to the entry artists A and B with a mouse cursor (not shown). ), The music information of the corresponding music is stored in the HD in the server computer 102.
The data is read from the hard disk of D11, downloaded to the client PC0 via the communication network, and reproduced.

The comparison evaluation page is provided with an evaluation switch for selecting and voting a favorite one of the two music pieces that have been compared and listened to. The evaluation switch is configured by a radio switch, and can designate one of “select one of them” or “select neither”. In addition, it may be possible to instruct “select both”. The evaluator clicks the voting switch after indicating the evaluation result in this way, and the evaluation result is transmitted to the server computer 102.

When the evaluation result is transmitted, server computer 102 updates the music information associated with entry artists A and B. At this time, it is preferable to display that the music information has been updated on the comparative evaluation page.

The above processing is repeated, and when the evaluator finds not only the comparative evaluation but also a music piece to be evaluated in detail, the detailed evaluation switch (“GO TO / REV”)
Clicking the switch labeled "IEW ROOM") displays a detailed evaluation page on the browser. Songs that can be evaluated by this detailed evaluation page are displayed before moving to this detailed evaluation page. One of the two songs selected on the comparative evaluation page.

On the detailed evaluation page, similarly to the conventional music evaluation apparatus, a score is given to each of a plurality of preset evaluation items, and one of “good”, “normal” or “bad” is assigned. It is configured to be selectable. Note that the evaluation method on the detailed evaluation page uses only a well-known method, and a detailed description thereof will be omitted.

In the present embodiment, detailed information on two songs to be evaluated, specifically, song names and singer names are not displayed on the screen of the comparative evaluation page. By not displaying detailed information about a song in this way, fraudulent voting using detailed information (such as voting only for a specific singer, regardless of the rating of the song itself, etc.) No voting) can be avoided, and a pure reputation for the song can be obtained. Of course, the present invention is not limited to this, and detailed information about the music may be displayed. However, it is preferable not to display the detailed information about the music in that the evaluator can intuitively evaluate the music.

Also, in the present embodiment, the number of songs to be evaluated is two, but this is only for convenience, and three or more songs may be presented simultaneously.

Next, this control processing will be described in detail.

FIG. 5 shows a music evaluation apparatus according to the present embodiment, in particular, client PC 0 and server computer 102.
9 is a flowchart showing a procedure of a process of moving to a comparison evaluation page executed by each CPU 5 of FIG. This processing is
The processing after the client PC0 accesses the music evaluation site of the server computer 102 via the communication network and the server computer 102 transmits the file of the front page of the music evaluation site to the client PC0 in response thereto is shown.

In the figure, first, the client PC 0
In a state where the front page of the music evaluation site is displayed on the browser of (1), the evaluator requests a move to the comparative evaluation page for performing the comparative evaluation (step S1).
And the transfer request is transmitted to the server computer 102. In response, the server computer 102 generates a screen data file for displaying the comparison evaluation page,
For example, the file is read from the hard disk of the HDD 11 of the server computer 102 (step S11), and the read screen data file is transmitted to the client PC 0 (step S12). Here, the screen data file refers to a file including screen data for displaying the comparison evaluation page on the browser of the client PC 0. The screen data file is created in advance and stored in the HDD 11 of the server computer 102. Is stored on the hard disk. File format is client PC
0, but may be of any format as long as it can be displayed by the browser running on HTM0.
Use the one described in L (Hypertext Markup Language).

When the client PC0 receives the screen data file transmitted from the server computer 102, it displays a comparative evaluation screen according to the received screen data file on the browser (step S2). That is, the comparative evaluation screen of FIG. 4 is displayed on the display device 9 of the client PC0.

Then, it is determined whether or not the evaluator has clicked on various switches provided on the comparative evaluation screen, specifically, any one of the PLAY switch, the evaluation switch, the voting switch, and the detailed evaluation switch. When one of the switches is operated, a switch operation process corresponding to the switch is executed (step S3 →
(S4 → S5) On the other hand, if none of the switches is operated, the process waits until one of the switches is operated (steps S3 → S4 → S3).

FIG. 6 is a flowchart showing a procedure of the PLAY switch operation process which is one of the processes during the switch operation process and is started when the PLAY switch is clicked. The PLAY switch operation process also includes a process executed by the CPU 5 of the client PC 0 and a process executed by the CPU 5 of the server computer 102, similarly to the process of moving to the comparison evaluation page.

In FIG. 6, first, a request is made to play back a music piece corresponding to the clicked switch of the two PLAY switches provided on the comparison evaluation screen (step S21). In response to this, the server computer 102 searches for the music information corresponding to the music requested to be reproduced, reads out the performance data included in the music information (step S31), and The data is transmitted to the client PC0 (step S32).

The client PC0 reproduces a music piece according to the performance data transmitted from the server computer 102 (step S22). Here, the music reproduction method includes a so-called streaming reproduction in which the server computer 102 transmits the performance data one by one and the client PC 0 sequentially reproduces the transmitted part one by one. After the transmission of the performance data is completed, there is a so-called download reproduction in which reproduction of the performance data is started on the client PC0 side, and any reproduction method may be adopted.

Note that this PLAY switch operation processing includes the following steps.
The process ends when the reproduction of the performance data for the music has been completed. After the completion, the process returns to the process of detecting the switch operation again, that is, the processes of steps S3 and S4 in FIG.

FIG. 7 is a flowchart showing a procedure of an evaluation switch operation process which is one of the processes during the switch operation process and is started when the evaluation switch is clicked. The evaluation switch operation process is different from the process of moving to the comparative evaluation page, and is different from the process of moving to the comparison
It is composed of only the processing executed by the PU5.

In FIG. 7, first, the evaluation display on the screen is changed in accordance with the operation of the evaluation switch (step S).
41). As described above, since the evaluation switch is constituted by two radio switches, the selection switch is selected in a state where either switch is selected (the selected state is indicated by a black dot in the switch). When a switch that is not selected is clicked and selected, the selected switch switches from the former to the latter. In this embodiment, as described above, it is possible to set a state in which none of the switches is selected. To enter this state, for example, click again on the selected switch,
The selection state may be canceled so that both switches are not selected.

Next, the contents of the new evaluation are recorded in the evaluation buffer (step S42). Here, the content of the evaluation set by the evaluation switch, that is, the data indicating the music selected by the evaluator (selected as a more favorite music) is stored in the RAM 7 of the client PC 0. It is configured to be recorded (stored) in an evaluation buffer secured at a predetermined position.

The evaluation switch operation process also returns to the process of detecting a switch operation again, that is, the processes of steps S3 and S4 in FIG. 5 each time one process is completed.

FIG. 8 is a flowchart showing a procedure of a voting switch operation process which is one of the processes during the switch operation process and is started when the voting switch is clicked. The voting switch operation process is also performed in the same manner as the process of moving to the comparison evaluation page, except that C
It is composed of a process executed by the PU 5 and a process executed by the CPU 5 of the server computer 102.

In FIG. 8, first, the client PC 0
Reads the contents of the evaluation stored in the evaluation buffer (step S51), converts the read contents of the evaluation into evaluation result data, and transmits the data to the server computer 102 (step S52). Here, the evaluation result data includes, in addition to the contents of the evaluation itself stored in the evaluation buffer, data indicating the music information of the current evaluation target music, that is, the two pieces of music evaluated this time. At least, the client PC0 includes:
Such evaluation result data is created and transmitted to the server computer 102.

Upon receiving the evaluation result data from the client PC0, the server computer 102 updates the evaluation data of the music piece to be evaluated based on the received evaluation result data (step S61).

Then, two new songs to be evaluated are selected from the songs recorded in the presented song information (step S62), and the selected two new songs are notified to the client PC0 (step S63). .

As a method of selecting a music piece to be evaluated,
For example, the following three methods can be used. That is, (1) a method of determining randomly from among the songs recorded in the presented song information, (2) a method of combining all the songs recorded in the presented song information in a league match format, and (3) a recording in the presented song information. This is a method of combining all the songs that are played in a tournament battle format.

In the method (1), two songs are randomly selected from the songs recorded in the presented song information, and the two songs are determined as new songs to be evaluated. If the two randomly selected songs are the same song or the same song as the song currently being evaluated, random selection is repeated until such a condition is no longer reached .

In the above method (2), the history of the combinations realized (presented) as the music to be evaluated is stored, and the combination of the music to be evaluated is determined by random selection. If a new combination occurs, random selection is repeated until a new combination occurs.

In the above method (3), the music piece on the evaluated (voted) side is left as it is, and the other (non-evaluated) music piece is randomly selected from music pieces that have not yet been selected. To a new song. If both are evaluated or neither is evaluated, both songs are changed to new songs (selected at random).

Next, upon receiving this notification from the server computer 102, the client PC0 sets the notified music as a new music to be evaluated (step S5).
3). Specifically, when the PLAY switch is operated, the music data in which music data should be read,
Information indicating which piece of music information the evaluation result data should be reflected in is stored (set).

Note that this voting switch operation process also returns to the process of detecting a switch operation again, that is, the processes of steps S3 and S4 in FIG. 5 every time one process is completed.

FIG. 9 is a flowchart showing a procedure of the detailed evaluation switch operation process which is one of the processes during the switch operation process and is started when the detailed evaluation switch is clicked. The detailed evaluation switch operation process also includes a process executed by the CPU 5 of the client PC0 and a process executed by the CPU 5 of the server computer 102, similarly to the process of moving to the comparison evaluation page.

In FIG. 9, first, the evaluator requests a move to the detailed evaluation page by clicking on the detailed evaluation switch (step S71), and the move request is transmitted to the server computer 102. The server computer 102 reads a screen data file for displaying the detailed evaluation page from, for example, the hard disk of the HDD 11 of the server computer 102 (step S81), and transmits the read screen data file to the client PC 0 (step S81). S8
2). Here, the screen data file refers to a file including screen data for displaying a detailed evaluation page on the browser of the client PC 0. The screen data file is created in advance and stored in the HDD 11 of the server computer 102. Is stored on the hard disk. The file format may be any format as long as it can be displayed by the browser activated on the client PC0, but typically, the format described in HTML is used.

When the client PC0 receives the screen data file transmitted from the server computer 102, it displays a detailed evaluation screen according to the received screen data file on the browser (step S72). When the user moves to the detailed evaluation page by operating the detailed evaluation switch, the comparative evaluation (function) ends at that point, and the process of moving to the comparative evaluation page in FIG. 5 ends. Completion of the process of moving to the comparison evaluation page,
This is performed, for example, when an instruction to move to another page or an instruction to end the operation of the music evaluation apparatus is issued.

The detailed evaluation screen displayed in this way is provided with various switches for inputting the evaluation by the evaluator, similarly to the comparative evaluation screen, and the evaluator clicks these switches to obtain desired switches. Is configured to be able to perform a detailed evaluation of the music piece. The music to be evaluated in detail can be selected on the detailed evaluation screen. For example, before moving to the detailed evaluation screen, it is possible to select one of the two songs that have been evaluated on the comparative evaluation screen.

The result of the detailed evaluation input by the evaluator on the detailed evaluation screen is stored in the HD of the server computer 102.
It is recorded in the evaluation data in the music information stored in the hard disk of D11.

Also, in the present embodiment, the client PC0 has been mainly described as the client terminal accessing the server computer 102, but this is only for convenience, and other client terminals, that is, the client PC103 and the client portable terminal are not used. The terminal 103 'can access the server computer 102 in the same manner as the client PC0.

As described above, in the present embodiment, a plurality of presented songs are compared and listened to, and a favorite song is selected from among them for voting, so that the songs can be evaluated while being enjoyed like a game.
