The operation of the embodiment having the above-mentioned structure will be described below. This operation will be described using a functional block diagram shown in FIG. 3 showing functions of the electronic music device realized by the hardware circuit and program processing shown in FIG. 2 . In FIG. 3, the temporary storage part 64a is a volatile storage area provided in the RAM 64 of FIG. FD, etc. The browser part BR is a function realized when the CPU 21 executes the browser program shown in Figure 4. The reproduction control part CT is a function realized when the CPU 21 executes the reproduction control program shown in Figure 4. Thus, in the following description it will be assumed that the browser part BR and the reproduction control part CT execute the browser program and the reproduction control program, respectively. It should be noted that the other parts of the electronic music device in FIG. 3 are the same as those in FIG. 2 that are marked with the same reference numerals.

In step B11 of FIG. 4, when the user operates the input operation element group 41 to start the browser program, the browser part BR accesses the distribution page of the content distribution server 30 to request content distribution page data from the content distribution server 30. In step S11, the content distribution server 30 transmits content distribution page data to the browser part BR in response to the request. In step B12, the browser part BR receives the transmitted content distribution page data, and displays the content distribution page indicated by the received content distribution page data on the display device 42. In step B13, when the user clicks on a link displayed on the displayed content distribution page, the browser part BR requests the content distribution server 30 for a reproduction mode designation file corresponding to the link. Then, as a response to the request, the content distribution server 30 transmits the requested reproduction mode designation file to the browser part BR.

A specific example will be used to explain the operation of the browser part BR when the browser part BR receives the reproduction mode specifying file from the content distribution server 30 as described above. Initially, the content distribution page data sent from the content distribution server 30 to the browser part BR indicates a title page, and thus the title page will be displayed on the display device 42 . The title page is a menu, as shown in FIG. 7(A), in which options for specifying usage purposes of the music content are listed, such as karaoke, teaching, BGM, and the like. When the user operates the input operation element group 41 to select an option from the menu, the next screen displayed on the display device 42 will be a selection menu from which the user can correspond to the musical genre for the instrument (for example, piano music composition, Guitar music, etc.) select "system selection reproduction" (a plurality of music works determined in advance on the content distribution server 30), or select a specific genre name such as jazz, rock, folk music, etc., wherein the music genre belongs to the aforementioned options and are categorized for each major instrument. When the user selects the "system selection reproduction" of the musical instrument corresponding to the music genre required, the reproduction mode designation file stored in the content distribution server 30 and corresponding to the "system selection reproduction" of the selected musical instrument corresponding music genre will be sent to Browser Widget BR.

On the other hand, when the user selects the desired type name of the musical instrument corresponding to the musical genre in the display state shown in Figure 7 (B), then the corresponding music genre belonging to the selected musical instrument will be displayed as shown in Figure 7 (C). Various genres such as jazz, rock, folk, etc. If the user selects a genre, a reproduction mode designation file stored in the content distribution server 30 belonging to the music genre corresponding to the instrument and corresponding to the selected genre is sent to the browser part BR.

As described above, when a certain reproduction mode specifying file is transmitted from the content distribution server 30 to the browser part BR, in step B14, the browser part BR receives the transmitted reproduction mode specifying file and supplies it to the reproduction control part. CT. In step S10, the reproduction control unit CT executes the processing of the reproduction control program using the supplied reproduction mode specifying file. As shown in detail in FIGS. 5 and 6, in the playback control program, it is judged in step C11 whether the distribution type data specified in the provided playback mode specifying file is download or streaming.

If the download type is specified, the reproduction control section CT acquires all content files specified by the content URL from the content distribution server using the reproduction content list (content URL) in the reproduction mode designation file in step C12. Then, all the acquired content files are recorded and stored in the recording medium 65a. In this case, the distribution server 30 transmits the content file to the reproduction control unit CT through the process of step S13.

On the other hand, if the distribution type data in the reproduction mode designation file assigns streaming media as the distribution type, then stop the function of the output interface circuit 67 in step C13 to prohibit MIDI data and digital data from the MIDI output terminal 67a and digital output. Terminal 67b is output to the outside. Then, in step C14, stop the input function of the operating elements used for data storage and editing in the input operating element group 41, to prohibit the operation of these operating elements. Thus even if the content file is obtained, it is possible to Storage, editing, or external output of acquired content files or various data generated based on acquired content files to the recording medium 65a as described later is prohibited.

After the process of step C14, the reproduction control section CT controls the display screen of the display device 42 based on the screen control data in the reproduction mode designation file. Specifically, if the screen control data indicates a browser, browser screens such as those shown in FIG. 7(A) to (C) are displayed. If the screen control data indicates lyrics, the screen is converted to a screen for displaying lyrics. If the screen control data represents a musical score, the screen is converted to a screen for displaying a musical score. It should be noted that actual lyrics and score are not displayed in the display of the lyrics and score since the actual music content is not acquired.

Subsequently, in step C16, the reproduction control part CT controls the display device 42 to display the content detail information (name, composer, singer, copyright information) of the music content based on the content detail information of the title content list data in the reproduction mode specifying file. (See Fig. 7(D) to Fig. 7(F)). After the process of step C16, in step C17, the reproduction control section CT requests the content distribution server 30 for the content file specified by the same URL using the content URL of the title content list data located in the reproduction mode specifying file. Then, the reproduction control section CT acquires the content file distributed from the content distribution server 30 and writes it in the temporary storage section 64a.

After acquiring the content file, the reproduction control section CT determines in step C18 whether the automatic reproduction control data in the reproduction mode specifying file indicates "automatic reproduction". If it indicates "automatic reproduction", the program proceeds to the processing of step CT21 shown in FIG. 6 . If the automatic reproduction control data does not represent "automatic reproduction", then in step C18, make the judgment of "no", then, repeat the loop processing of steps C19 and C20, until the user inputs the start operation in the operation element group 41 by operation element while indicating the beginning. In this loop processing, the reproduction control section CT accepts the operation of the screen transition operation element in the input operation element group 41 through the processing at step C20. In the case where the user operates the screen switching operation element, the display screen on the display device 42 is changed in accordance with the operation instruction of the screen switching operation element. For example, by this operation, the display screen on the display device 42 displaying content detail information is also converted to the browser screen shown in FIG. 7(A) to (C). Through the processing of step C20, the user can freely switch the display screen specified by the screen control data in the reproduction mode specification file on the display device 42 before the reproduction of the music content. When the start is instructed by starting the operation on the operating element during the loop processing of steps C19 and C20, a judgment of "YES" is made in step C19, and then the procedure proceeds to the processing of step C21 in FIG. 6 .

In step C21, the musical piece is reproduced using the music content stored in the temporary storage unit 64a, and the loop processing of step C22 to step C26 is repeatedly executed. In this loop processing, musical composition data included in the musical content stored in the temporary storage unit 64a is continuously output to the tone generating circuit 43 in accordance with the progress of the musical composition. The tone generation circuit 43 continuously generates tone signals corresponding to the musical composition data, and outputs the generated tone signals through the acoustic system 64, thereby reproducing the musical composition using the musical composition data included in the musical content. In addition, as long as the processing of step C20 does not instruct screen transition, the display screen on the display device 42 is switched from the content detail information (name of music content, composer, singer, copyright information) to the information set by step C15 along with the reproduction of the musical instrument. A screen display of the processing settings. For example, in the case where the screen control data indicates lyrics, the display screen on the display device 42 is switched from the content detail information shown in FIG. 7(D) to the display of lyrics shown in FIG. 7(E). Furthermore, in the case where the screen control data represents a musical score, the display screen on the display device 42 is switched from the content detail information shown in FIG. 7(F) to the display of the musical score shown in FIG. 7(G). However, in the event that the processing at step C20 instructs a screen change, the display screen on the display device 42 will be switched in accordance with the instruction at step C20.

When in the loop processing of steps C22 to C26, when the reproduction of a music composition in the music content specified by the reproduction content list data in the reproduction mode designation file ends, the next content list in the reproduction mode designation file provided The content URL of the data will be used to obtain the content file specified by this URL from the content distribution server 30, thereby by the processing of step C22, delete the content file stored in the front of the temporary storage part 64a, and write the newly obtained content file Into the temporary storage part 64a. Also in this case, through the processing of step S13 in Fig. 4, the content distribution server 30 sends the content file to the reproduction control part CT. Then, reproduce the musical composition in the newly acquired content file, and simultaneously as above As shown, the lyrics or score are displayed on the display device 42.

During the loop processing, it is judged at step C23 whether or not the reproduction of the music content specified by the reproduction content list in the reproduction mode specification file has ended. If the reproduction of the music content has not ended, it is judged in step C24 whether or not the user instructs to stop by operating on the stop operation element in the input operation element group 41 . If the user does not instruct to stop, then in step C25, the reproduction mode of the music content is controlled according to the operation on the reproduction control operating elements of the input operating element group 41 such as pause, restart, fast forward or playback. In step C26, the operation on the screen conversion operation element in the input operation element group 41 is accepted, and when the user operates the screen conversion operation element, similar to the processing of step C20, the display screen on the display device 42 will be changed according to The screen is switched by operating commands on the operating elements. Through the processing of step C26, the user can freely switch the display screen on the display device 42 designated by the screen control data in the reproduction mode designation file during the reproduction of the music content.

In the loop processing, when the reproduction of the music content designated by the reproduction content list in the reproduction mode designation file ends, a judgment of "Yes" is made in step C23, and then the program proceeds to the processing of step C27. It is judged at step C27 whether the repeat reproduction control data in the reproduction mode specifying file indicates "repeat". If it indicates "repeat", the loop processing of steps C22 to C26 is executed again. If "repeat" is not indicated, a "No" judgment is made in step C27, and then the program proceeds to the processing of steps C28 to C30. When the user instructs to stop by operating the stop operating element in the input operating element group 41 during the loop processing of steps C22 to C26, a judgment of "Yes" is made in step C24, and the program proceeds to steps C28 to C30 processing.

In step C28, the function of the output interface circuit 67 returns to canceling the prohibition of output of MIDI data and digital data from the MIDI output terminal 67a and the digital output terminal 67 to the outside. In step C29, the input function of the operation elements for storage and editing of data in the input operation element group 41 is returned to cancel prohibition of operations on these operation elements. In step C30, the music content stored in the temporary storage section 64a is deleted, and the execution of the reproduction control program is ended.

As for the content file downloaded to the recording medium 65a by the processing of step C13, the content file is transferred to the temporary storage section 64a so that the music content can be reproduced by a separately prepared reproduction program constituted by the processing of steps C18 to C26. In this case, the output interface circuit 67 functions to output music content to the outside through the MIDI output terminal 67a, and to output digital data representing reproduced sound to the outside through the digital output terminal 67b. In addition, the user can read out the content file stored in the recording medium 65a at any time by executing a separately prepared program, freely use the content file, and edit music content. Edited content files can also be re-stored and exported externally.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the invention.

For example, although the above-described embodiment provides two output terminals, the MIDI output terminal 67a and the digital output terminal 67b, only one of the two output terminals may be provided. In addition, the electronic music device may have only an editing function or a storage function. Also, the electronic music device may have only a lyrics display function or a score display function.

The above-described embodiments provide screen control data shared by a plurality of content files in a reproduction mode specifying file. However, in addition to this, screen control data representing a display screen of a browser, lyrics, or musical scores may also be provided to each content file designated by the reproduction content list data. This makes it possible to implement content distribution services in a variety of reproduction ways, for example, for the same piece of music, users start listening to the reproduced music only on the browser display screen; then, use the lyrics display screen to practice singing; finally, use the score display On-screen practice playing an instrument. In this case, screen control data may be included in the reproduced content list. Additionally, screen control data can be included in content files as system-specific messages.
