At Step SA 11 , the user is urged to determine whether the selected music data is actually downloaded. If the user determines to download it, a download request is transmitted to the music data providing apparatus 1 a to thereafter advance to the next Step SA 12 as indicated by a YES arrow. If the user does not determine to download it, a message that the music data is not downloaded is transmitted to thereafter advance to Step SA 13 as indicated by a NO arrow.

At Step SA 12 , a downloading process to be described later is executed.

At Step SA 13 , the user is urged to determine whether other music data is downloaded. If the user determines to download, the flow advances to the next Step SA 14 as indicated by a YES arrow to execute again the music data receiving process starting from Step SA 1 . If the user does not determine to download, the flow advances to Step SA 15 as indicated by a NO arrow to terminate the music data receiving process.

Next, with reference to FIGS. 1 and 2, FIGS. 6A to 6 C, and FIGS. 7 and 8, the music data providing process will be described which is executed by CPU 16 of the music data providing apparatus 1 a (computer 1 ).

At Step SB 1 , the music data providing process starts to advance to the next Step SB 2 .

At Step SB 2 it is checked whether there is any access from a user (music data receiving apparatus). If there is an access from the music data receiving apparatus, the flow advances to the next Step SB 3 as indicated by a YES arrow. If there is no access from the music data receiving apparatus, Step SB 2 is repeated as indicated by a NO arrow until an access from the music data receiving apparatus occurs.

At Step SB 3 , the charging account opening file is transmitted to the music data receiving apparatus. Thereafter, the flow advances to Step SB 4 .

At Step SB 4 , the music data providing apparatus 1 a receives either the charging account information or the charging account opening data from the music data receiving apparatus. If the charging account information is received, it can be known that the accessing user has already a charging account. In this case, therefore, the user name, password and the like are verified by using the user charging account database DB 1 to thereafter advance to Step SB 6 as indicated by a YES arrow.

If the charging account opening data is received, it can be known that the accessing user wishes to open a new charging account. Therefore, the flow advances to the next Step SB 5 as indicated by a NO arrow.

At Step SB 5 , in accordance with the charging account opening data received at Step SB 4 , a user charging account is opened and stored in the user charging account database DB 1 . Thereafter, the flow advances to the next Step SB 6 .

At Step SB 6 , the music data list HM is transmitted to the music data receiving apparatus. Thereafter, the flow advances to the next Step SB 7 .

At Step SB 7 , the music data providing apparatus 1 a receives the information of the music data selected at Step SA 9 and transmitted in the music data receiving process and the determination of whether the advertisement is appended. After the information is received, the flow advances to the next Step SB 8 as indicated by a YES arrow if the user wished to append the advertisement, whereas the flow advances to Step SB 14 as indicated by a NO arrow if the user did not wish to append the advertisement.

At Step SB 8 , the music data price (Db 3 −x) is transmitted to the music data receiving apparatus, the music data price (Db 3 −x) is the music data price (Db 3 ) of the music data selected by the user, reduced by the advertiser charge (x) incurred upon the advertiser. Thereafter, the flow advances to the next Step SB 9 . For example, if the music data price (Db 3 ) is 300 Yen and the advertiser charge (x) is 200 Yen, the price actually to be paid by the user (the price charged to the user charging account) is a reduced music data price (Db 3 −x), i.e., 100 Yen. The advertiser charge (x) is settled by the advertisement fee collected from the advertiser.

The advertiser charge (x) may be changed depending upon the kind of appended advertisement data. For example, if the advertisement data and advertisement music data are appended, the advertiser charge (x) may be raised more than that only the advertisement data is appended.

Further, the advertiser charge (x) may also be changed depending upon the advertisement data display method or advertisement music data performance method. Specifically, as described later, if the advertisement is displayed or advertisement music data is reproduced only when the music data is downloaded, the advertiser charge (x) may be lowered, whereas if the advertisement is displayed or advertisement music data is reproduced every time when the music data is reproduced, the advertiser charge (x) may be raised.

In such cases, at Step SA 9 of the music data receiving process described earlier, the user may be urged to determine whether the advertisement is appended in what advertisement pattern. Alternatively, fees for various advertisement patterns may be contained in the reduced music data price (Db 3 −x) to be transmitted at Step SB 8 to allow the user to select a desired advertisement pattern.

At Step SB 9 , in accordance with the user determination at Step SA 11 of the music data receiving process, the music data providing apparatus 1 a receives a download request or the information of not to download, from the electronic musical apparatus 2 . Upon reception of the download request, the flow advances to the next Step SB 10 . Upon reception of the information of not to download, the flow advances to Step SB 11 whereat the flow returns to Step SB 1 to resume the music data providing process.

At Step SB 10 , the music data MD selected by the user and appended with the advertisement display data AD (or advertisement data AD and advertisement music data AM) is transmitted to the electronic musical apparatus 2 . In this case, the advertisement data AD (or advertisement data AD and advertisement music data AM) is transmitted first before the music data MD is transmitted. The music data MD is transmitted after the transmission of the advertisement data AD (or advertisement data AD and advertisement music data AM) is completed. Thereafter, the flow advances to Step SB 15 .

The advertisement data AD (or advertisement data AD and advertisement music data AM) is automatically selected from a plurality of such data stored in the external storage unit 17 a of the music data providing apparatus 1 a.

It is preferable that the advertisement data AD (or advertisement data AD and advertisement music data AM) already downloaded by the same user is not downloaded.

If there is the advertisement music data AM, the advertisement display data AD is first transmitted. In this manner, it becomes possible to display an advertisement corresponding to the advertisement display data during downloading the succeeding data.

Prior to transmitting each data, identification data for identifying the type of data or the like may be transmitted. In this manner, it becomes possible for the music data receiving apparatus to recognize the type of data or the like before the data is actually downloaded.

The music data MD transmitted at Step SB 10 is the MIDI format data (SMF file). If the mobile phone 3 is used as the music data receiving apparatus, the music data MD of the MIDI format stored in the external storage unit 17 a of the music data providing apparatus 1 a is transmitted after it is converted into the format capable of being reproduced by the mobile phone 3 . Similarly, the advertisement display data AD and advertisement music data AM are also transmitted after they are converted into the format capable of being reproduced by the mobile phone 3 . The music data, advertisement display data and advertisement music data capable of being reproduced or displayed by the mobile phone 3 may be prepared beforehand to make format conversion unnecessary.

At Step SB 12 , the music data price (Db 3 ) for the music data selected by the user is transmitted to the music data receiving apparatus. Thereafter, the flow advances to Step SB 13 . In this case, the reduced music data price (Db 3 −x) with an appended advertisement may be transmitted together with the music data price (Db 3 ). If the user looking at the reduced music data price (Db 3 −x) with an appended advertisement desires to append the advertisement, the flow may be structured to advance to Step SB 9 .

At Step SB 13 , in accordance with the user determination at Step SA 11 of the music data receiving process, the music data providing apparatus 1 a receives the download request or the information of not to download, from the electronic musical apparatus 2 . Upon reception of the download request, the flow advances to the next Step SB 14 . Upon reception of the information of not to download, the flow advances to Step SB 11 whereat the flow returns to Step SB 1 to resume the music data providing process.

At Step SB 14 , the music data MD selected by the user is transmitted to the electronic musical apparatus 2 . Thereafter, the flow advances to Step SB 15 .

At Step SB 15 , the charging process is executed to the user charging account. The charging price changes with whether the transmitted music data was appended with the advertisement data or not. If the advertisement data is not appended, the original music data price (Db 3 ) is charged to the user charging account. If the advertisement data is appended, the reduced music data price (Db−x) is charged to the user charging account. Thereafter, the flow advances to the next Step SB 16 .

At Step SB 16 , the flow returns to Step SB 1 to resume the music data providing process.

As described so far, according to the embodiment of the invention, by appending advertisement data to music data, an advertisement fee can be received from the advertiser so that the distribution price for the music data can be reduced.

Further, according to the embodiment of the invention, advertisement display and advertisement sound reproduction corresponding to advertisement data are performed when music data or the like is downloaded so that advertisement can efficiently made to users of electronic musical apparatus.

Still further, if only the advertisement display data is appended to music data, sounds of the music data can be listened without being disturbed by the advertisement.

Furthermore, even if the advertisement music data is appended, sounds of the music data can be listened without being disturbed by the advertisement if it is set in such a manner that sounds of the advertisement music data are reproduced only during downloading the music data and only the advertisement corresponding to the advertisement display data is displayed during the later automatic musical performance.

In this embodiment, although the music data such as MIDI data and the advertisement data are separately stored and downloaded, they may be combined. For example, the advertisement display data and advertisement sound data may be embedded in the music data such as MIDI data.

Also in this embodiment, although an electronic musical instrument with a keyboard, a mobile phone with a musical tone generator, and the like are used as the electronic musical apparatus, other apparatus may also be used if they can download music data and advertisement data and have an automatic performance function and a display for displaying an advertisement. For example, a karaoke system, a game device, and an automatic performance piano may also be applicable. The type of an electronic musical instrument is not limited only to a keyboard type instrument, but other types may also be used such as a stringed instrument, a wind instrument and a percussion instrument. The electronic musical apparatus is not limited only to an electronic musical instrument of the type that the components thereof such as a musical tone generator and an automatic performance apparatus are all built in one integrated body, but these components may be separate and interconnected by communication devices such as MIDI and various networks.

The embodiment may be realized by a personal computer installed with a computer program and the like realizing the functions of the embodiment.

In such a case, the computer program and the like realizing the embodiment functions may be stored in a computer readable storage medium such as a CD-ROM and a floppy disk and supplied to users.

If the personal computer is connected to a communication network such as a LAN, the Internet and a telephone line, the computer program and various data may be supplied to the personal computer via the communication network.

The running information of each electronic musical apparatus may be transmitted to the music data providing apparatus 1 a to charge each time an automatic musical performance is made by using music data or to utilize the information for statistical investigation such as data acquisition of popular music.

This system may be used as an on-line education system for the performances of musical instruments. In this case, information on subject music and performance operation at the electronic musical apparatus 2 is transmitted to the music data providing apparatus 1 a to store data of performance skill, training frequency and the like of the user in the external storage unit 17 a of the music data providing apparatus 1 a . The stored data is automatically analyzed to present the user with the next subject music and performance target.

The present invention has been described in connection with the preferred embodiments. The invention is not limited only to the above embodiments. It is apparent that various modifications, improvements, combinations, and the like can be made by those skilled in the art.
