Embodiments of the present invention will be described below with reference to the drawings.

<1. First Embodiment> First, a first embodiment of the present invention will be described. FIG. 1 is a diagram illustrating a schematic configuration of a music distribution system 1 according to the first embodiment, and FIG. 2 is a block diagram illustrating a functional configuration of the music distribution system 1.

As shown in FIG. 1, the music distribution system 1 is configured such that the computer 10 and the portable telephone 30 can communicate with each other via the communication network 3. Then, by transmitting request data from the mobile phone 30 to the computer 10, the computer 10 extracts music data corresponding to the request data, and transmits the music data to the mobile phone 30. ing. Therefore, in the mobile phone 30, the computer 1
From 0, music data can be downloaded and obtained, and a ring melody based on the music data can be set.

A speaker 31 for generating sound, a liquid crystal display 32 for displaying an image and the like, and an operation button 3 having a plurality of button switches are provided on the outer surface of the mobile phone 30.
3 and a microphone 34 for performing voice input.

Also, as shown in FIG.
Is a request data generation unit 30
1. Communication circuit 302, RAM (Ramdom Access Memory)
303 and a ringtone melody setting unit 304.

The request data generation unit 301 generates request data for generating music data based on the operation of the operation button 33 by the user. The request data includes, for example, information for specifying music such as a music title and a singer name, and information on the model of the mobile phone 30. And this request data is
It is provided to the communication circuit 302.

The communication circuit 302 has a function of transmitting request data obtained from the request data generator 301 to the computer 10 installed on the base station side via the communication network 3. Further, the communication circuit 302 has a function of receiving data from the computer 10 via the communication network 3.

The incoming call melody setting unit 304
The mobile phone 30 has a function of setting the music data obtained in step 02 as a ringing melody of the mobile phone 30, and the function of the ringing melody setting section 304 generates a melody set from the speaker 31 at the time of an incoming call as a ringtone.

On the other hand, the computer 10 has a communication circuit 10
1, a model identification unit 102, a transmission data extraction unit 103, and a music database 104.

The communication circuit 101 transmits and receives data to and from the mobile phone 30 via the communication network 3.

The model specifying unit 102 analyzes information on the model included in the request data and specifies the model of the mobile phone 30 that has transmitted the request data. And
The model specifying unit 102 provides the transmission data extracting unit 103 with information for specifying music included in the request data and the model of the mobile phone 30.

The transmission data extraction unit 103 searches the music database 104 and extracts music data corresponding to the request data.

A large number of music data are recorded in the music database 104. This music data is, for example,
MIDI data or the like having a plurality of channels, and each channel stores performance data when music is reproduced with one tone (musical instrument) or the like.

FIG. 3 is a diagram showing an example of music data recorded in the music database. As shown in FIG. 3, the music data has a plurality of channels CH, and one performance data is stored for each channel.

For example, channel 1 stores chord data. This chord data is data that describes what chord is to be generated at what timing as the melody progresses.

The channel 2 describes performance data relating to the bass sound. Therefore, when reproduction is performed based on the performance data of channel 2, a sound corresponding to the base sound of the music can be generated.

Further, accompaniment data is stored in the channel 3, and by performing reproduction based on the accompaniment data, accompaniment can be added to the music. The accompaniment data includes chords. The difference between the accompaniment data and the chord data is that the accompaniment data is sequence data capable of reproducing music in the data storage order, whereas the chord data is not sequence data, but a chord to be used and a chord to be generated. The point is that the data is a list of timings.

The channel 4 stores the melody data as the main melody. This melody data is also sequence data.

Similarly, for each of the other channels, performance data for reproducing music with one tone (musical instrument) or the like is stored in each channel. However, the channel 16 stores not performance data but control data for performance. Then, among the performance data of each channel, sequence data for each tone is stored in all channels except channels 1 and 16. Therefore, all channels (channels 1, 1
Excluding 6. When music is reproduced based on the performance data of (1), the music can be reproduced with high sound quality.

Normally, MIDI data has at least 16 channels, and it is not defined which of the channels corresponds to which timbre.
In the recent SMF (Standard MIDI File) data for communication karaoke, for example, the data format shown in FIG. 3 is becoming a de facto standard. Therefore, as the music data shown in FIG. 3, SMF data used for communication karaoke and the like can be used as it is.

Since the music data is sequence data for performing a musical performance like a music score, data for reproducing the timbre needs to be separately provided in order to reproduce the timbre corresponding to each channel. Become. For this reason, the music database 104 stores a plurality of tone color data corresponding to so-called wave table data.

On the other hand, in the case where music is played as a ring tone in the mobile phone 30, high quality music is not required. Also, the number of sounds that can be sounded simultaneously when a ring tone is generated differs depending on the model of the mobile phone 30. For example, there is a type that can always generate a ringing melody with only a single tone, and a type that has a triad or a quadrature.

For this reason, when extracting the music data corresponding to the request data, the transmission data extracting unit 103 selects at least one channel from a plurality of channels included in the music data and transmits the performance data of the channel portion. Extract.

For example, when the portable telephone 30 is a model capable of producing a triad or a chord, the performance data of channels 3 and 4 of the music data shown in FIG. 3 is extracted. , The performance data relating to the melody and the accompaniment can be extracted. Then, in the mobile phone 30, by performing reproduction based on the performance data, it is possible to sound a ringtone with accompaniment in 3rd or 4th chords.

When the portable telephone 30 is a model capable of outputting only a single sound, only the performance data of the channel 4 out of the music data shown in FIG. Can be extracted. Then, in the mobile phone 30, by playing back based on the performance data, only the melody can be sounded with a single tone.

Further, when the portable telephone 30 can emit sounds of all the channels, if the performance data of all the channels is extracted, it is possible to sound a high-quality incoming melody.

When extracting at least one channel according to the model of the mobile phone 30, the transmission data extracting unit 103 also extracts tone color data corresponding to the channel at the same time. Then, the extracted performance data and tone color data are output to the communication circuit 101.

The communication circuit 101 provides the performance data and the timbre data to the mobile phone 30 via the communication network 3. As a result, the mobile phone 30 can acquire performance data and tone color data corresponding to the transmitted request data.

When the communication circuit 302 in the portable telephone 30 acquires the performance data and the timbre data via the communication network 3, it gives them to the incoming melody setting section 304.

Incoming melody setting section 304 is provided with communication circuit 3
When the performance data and timbre data are obtained from 02, they are temporarily stored in the RAM 303 and set as a ringing melody at the time of ringing. When a ringing melody is sounded, a signal is given to the speaker 31 based on the performance data and the tone color data stored in the RAM 303 to generate a ringing melody.

By operating as described above, the user can download the music desired to be set as a ring tone from the computer 10 and obtain performance data corresponding to the model of the mobile phone 30 owned by the user. Is possible. Therefore, in the music distribution system 1 of this embodiment, when music data is distributed to the mobile phone 30, it is possible to distribute music data suitable for the mobile phone 30.

On the other hand, since the computer 10 can use MIDI data used for communication karaoke and the like as music data, there is no need to separately prepare music data dedicated to the ringing melody of the portable telephone 30. It is possible to efficiently construct the music database 104. Also, the computer 10 can convert the same music data into performance data corresponding to the model of the mobile phone 30 and transmit the data to the mobile phone 30. Since it is not necessary to store performance data and the like for each model, the music database 104 can be efficiently constructed also in this regard.

In this embodiment, an example in which the computer 10 also extracts timbre data and transmits the same to the mobile phone 30 has been described. However, the present invention is not limited to this. To R
When the tone color data is stored in the AM 303 or the like in advance, it is not necessary to transmit the tone color data from the computer 10.

In this embodiment, music data is downloaded from the computer 10 to the portable telephone 30 via the communication network 3, and tone data necessary for reproducing the music data is also downloaded appropriately. Therefore, the storage capacity of the RAM 303 can be reduced as compared with a case where the timbre data for reproducing all timbres is stored in the mobile phone 30 in advance.
It is also possible to reduce the cost of the mobile phone 30.

Also, in this embodiment, the computer 10 automatically generates music data corresponding to the model of the mobile phone 30 according to the combination of each channel.
The configuration example in which the melody is transmitted as the incoming melody of the mobile phone 30 has been described. However, as a more advanced process, the following process may be performed.

That is, if the chord data of channel 1 among the music data shown in FIG. 3 is used, the chord progression of the music can be determined. Therefore, the computer 10
Using the chord progression and the melody data of channel 4, the required number of chords corresponding to the reproduction capability of the model of the mobile phone 30 is obtained, and sequence data for adding an accompaniment based on the number of chords is obtained. By generating the music data, it is possible to automatically generate music data having the optimum number of sounds for the model of the mobile phone 30. Then, by transmitting the music data to the mobile phone 30, the mobile phone 30 can set a ringing melody optimal for the model.

The automatic generation in this case will be specifically described. The automatic generation may be performed, for example, by changing the development of the chord constituent sounds so that the sum of the development form of the chord constituent sounds and the melody (one sound) becomes the maximum number of sounds that can be reproduced in the mobile phone 30. That is, the chord is Cm (sea minor), and when the chord is composed of two chords, the chords C and D
#. When the sound is composed of three chords, chords C and D #
And G. Further, when a chord is composed of four chords, the chords are C, D #, G, and C (one octave higher). In each of these cases, the number of constituent tones and the expanded form can be determined by a harmony theory, so that the computer 10 automatically determines the chord progression indicated in the chord data of channel 1 based on a predetermined rule based on harmony. You can do it.

Further, when there is a same sound separated by an octave unit, and if any of them is prioritized, for example, the top note (top sound) may be configured to be prioritized.

By such processing, MIDI data, which is music data, can be processed in accordance with the reproduction capability of the mobile phone 30, particularly the maximum number of simultaneous sounds, so that the same music data can be used for the model of the mobile phone 30. Accordingly, it can be converted into various music data. Further, if the music data is processed in accordance with the progression of chords, it is possible to perform not only processing according to the model of the mobile phone 30 but also processing according to a user's request. Become.

<2. Second Embodiment> Next, a second embodiment will be described. In the second embodiment, the schematic configuration of the music distribution system 1 is the same as that shown in FIG. FIG. 4 is a block diagram illustrating a functional configuration of the music distribution system 1 according to the second embodiment. In FIG. 4, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 4, the music distribution system 1 of this embodiment is different from the system of the first embodiment in that a portable telephone 30 has a ROM (Read Only Memory).
ry) 305 is provided.

The ROM 305 of the portable telephone 30 stores tone color data in advance in order to reproduce a tone of a predetermined channel included in the music data. The tone color data recorded in the ROM 305 may be, for example, basic tone color data (basic tone color data) for a piano or the like.

As described above, the portable telephone 30 is stored in the ROM 305.
Having basic tone data in advance, the computer 1
When “0” extracts performance data from music data according to the model of the mobile phone 30 and sends the data to the mobile phone 30, it is not necessary to give the tone data pre-recorded in the ROM 305 of the mobile phone 30 to the mobile phone 30. .

That is, the computer 10 specifies the model of the portable telephone 30 to which the request data has been transmitted in the model specifying unit 102, specifies the basic tone color data which the model has in advance, and includes the basic tone color data in the basic tone color data. When the performance data relating to the undesired timbre is extracted and transmitted to the mobile phone 30, only the timbre data for expressing the timbre of the performance data need be transmitted. For this reason,
The efficiency of the processing in the computer 10 can be improved, and the transmission efficiency at the time of data transmission can also be improved.

On the other hand, in the portable telephone 30, among the timbre data necessary for reproducing the music data, the timbres used in many kinds of music such as the piano timbres are stored in the ROM 305 in advance as basic timbre data. Has been recorded. Therefore, even if only the performance data is received from the computer 10, the mobile phone 30 can reproduce using the basic timbre data recorded in the ROM 305. Also, when performance data that cannot be properly reproduced with the basic timbre data is received, timbre data can be received along with the performance data, so that appropriate music can be reproduced. . Furthermore, storing only the basic tone data in the ROM 305 can reduce the storage capacity of the ROM 305 as compared with storing tone color data for reproducing all tone colors. It is also possible to reduce costs.

<3. Third Embodiment> Next, a third embodiment will be described. In the third embodiment, the schematic configuration of the music distribution system 1 is the same as that shown in FIG. FIG. 5 is a block diagram showing a functional configuration of the music distribution system 1 according to the third embodiment. In FIG. 5, the same components as those in the above embodiments are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 5, the music distribution system 1 of this embodiment is different from the system of the second embodiment in that
4 is provided with a tone conversion unit 201.

The ROM 305 of the mobile phone 30 stores one kind of tone data for each tone system, such as one kind of piano, one kind of organ,..., One kind of sound, as basic tone data. Has been recorded.

In general, GM (Ge
In the case of neral MIDI) data, there are eight timbre systems, and each timbre system has 16 types of timbres. For example, in the case of piano-based tones, there are 16 types of tones for different types of pianos, such as an acoustic grand piano and an electric piano. Therefore, since there are 16 types of timbres in 8 timbre systems, when reproducing all timbres recorded as GM data, a total of 128
It is necessary to have the timbre data of In addition, when the MIDI expansion bank is used, a maximum of 128 × 128 kinds of tone colors can be present, so that in order to reproduce all the tone colors, an enormous amount of tone data is required.

However, since high sound quality is not desired in the mobile phone 30, for example, the ROM 305 holds only sound color data relating to an acoustic grand piano. When the performance data is performance data for an electric piano,
The tone data is converted in order to reproduce the performance data with the tone color of the acoustic grand piano stored in the ROM 305 in advance. As described above, there is no significant difference in the musical expression even when the representative reproduction is performed with one tone color for each tone color system. Then, the ringing melody setting unit 30
Reference numeral 4 sets an incoming melody at the time of an incoming call based on performance data obtained from the computer 10 and timbre data read from the ROM 305 in order to generate an incoming melody with a tone converted by tone conversion.

By expressing the variation of the timbre of the MIDI data by the basic timbre as described above, it is possible to reduce the number of timbres required in the mobile phone 30.

More specifically, one method for expressing a basic tone will be described. For example, it is assumed that a tone color map of MIDI data is configured as shown in FIG. In FIG. 6, the timbre number DN is represented by two hexadecimal digits. If the upper digit is "0", the tone color number is a piano tone color, and if it is "1", the tone color number is an organ tone color. The lower digits indicate one timbre for each type.

Therefore, the timbre converter 201 can convert the 128 timbres into eight timbres by masking the lower digits of the timbre number DN. Note that the tone number DN
Is equivalent to masking the lower bits (more specifically, the lower 4 bits) when the tone color number DN is expressed in bits.

FIG. 7 is a diagram showing a timbre map on which timbre conversion has been performed in the timbre conversion unit 201. As shown in FIG. 7, in the timbre map of FIG. 6, the lower digits of the timbre number DN are masked, so that one timbre of the piano type and one timbre of the organ type are provided for each timbre system. 16
A map having one type of tone color is converted into a map having one type of tone color for each tone color system.

As a result, the ROM 305 of the portable telephone 30
If one of the basic tone data is used as the basic tone data for each tone system, and eight types of basic tone data are recorded in all the tone systems, the basic tone is used for the other tones. Alternatively, performance data can be reproduced.

As described above, the portable telephone 30 has the ROM 30
When the performance data relating to the timbres not stored in No. 5 is reproduced, the timbre conversion unit 201 converts the data into the basic timbres.
The reproduction is performed using the basic timbre data recorded in advance in M305. For this reason, the computer 10 does not need to transmit timbre data no matter what performance data is transmitted to the mobile phone 30, so that the computer 10 can perform efficient processing. Further, transmission efficiency when data is transmitted from the computer 10 to the mobile phone 30 can also be improved.

Further, in the mobile phone 30, the RO
There is no need to record timbre data for all timbres in M305, and performance data can be reproduced only by recording one basic timbre data for each timbre system as basic timbre data. . Therefore, the storage capacity of the ROM 305 can be reduced as compared with the case where tone color data for reproducing all tone colors is recorded, and the cost of the mobile phone 30 can be reduced.

<4. Fourth Preferred Embodiment> Next, a fourth preferred embodiment will be described. In the fourth embodiment, the schematic configuration of the music distribution system 1 is the same as that shown in FIG. FIG. 8 is a block diagram illustrating a functional configuration of a music distribution system 1 according to the fourth embodiment. In FIG. 8, the same components as those in the above-described embodiments are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 8, the music distribution system 1 of this embodiment differs from the system of the third embodiment in that a tone conversion unit 201 is provided on the computer 10 side.

In the computer 10, the transmission data extraction unit 103 extracts performance data according to the model of the mobile phone 30, and supplies the performance data to the timbre conversion unit 201. As described in the third embodiment, the timbre conversion unit 201 performs timbre conversion so as to use one type of timbre for each timbre system, for example, by masking the lower digits of the timbre number DN. Then, the computer 10 transmits the performance data to the mobile phone 30 via the communication network 3.

In the portable telephone 30, one kind of tone color data is stored in the ROM 305 in advance as basic tone color data for each tone color system. Therefore, when the performance data is reproduced in the ring tone melody setting unit 304, the tone color conversion has already been completed, so that the ring tone melody based on the basic tone color data and the performance data obtained from the ROM 305 can be generated from the speaker 31. it can.

As described above, the computer 10 is configured so that the tone color conversion unit 201 converts the tone data to the basic tone when transmitting performance data relating to the tone that is not stored in the ROM 305 of the mobile phone 30. For this reason, the computer 10 does not need to transmit the timbre data regardless of what kind of performance data is transmitted to the mobile phone 30, so that the transmission efficiency in transmitting the data can be improved.

In the portable telephone 30, the ROM
There is no need to record tone data relating to all tone colors in 305, and performance data can be reproduced only by recording one basic tone color data as basic tone color data for each tone color system. .

<5. Fifth Embodiment> Next, a fifth embodiment will be described. Also in the fifth embodiment, the schematic configuration of the music distribution system 1 is the same as that shown in FIG. FIG. 9 is a block diagram illustrating a functional configuration of the music distribution system 1 according to the fifth embodiment. In FIG. 9, the same reference numerals are given to the same components as those in the above embodiments, and the description thereof will be omitted.

As shown in FIG. 9, in the music distribution system 1 of this embodiment, the mobile phone 30 includes an operation button 33, a request data generator 301, and a communication circuit 30.
2. In addition to the above-described configuration of the incoming call melody setting unit 304 and the speaker 31, the information processing unit includes an information recognition unit 311, a liquid crystal display 32, and a RAM 312.

And a history database 106.

In the portable telephone 30, the request data generated by the request data generator 301 is sent from the communication circuit 302 to the computer 10 via the communication network 3.

When the computer 10 receives the request data, the model specifying unit 102 specifies the model of the mobile phone 30. At this time, the model identification unit 102 accesses the history database 106 and adds the content of the request data received from the mobile phone 30 (for example, information for identifying music such as a music title and a singer's name).

The transmission data extracting unit 103 extracts music data corresponding to the content of the request data from the music database 104 and transmits the music data to the advertisement database 10.
5 to extract advertisement data related to the content of the request data. For example, a search is performed based on the singer's name, and advertisement data such as new song information and concert information relating to the singer is extracted. Then, both the music data extracted from the music database 104 and the advertisement data extracted from the advertisement database 105 are provided to the communication circuit 101 and transmitted to the mobile phone 30 via the communication network 3.

Upon receiving the data from the computer 10, the information recognition unit 311 of the mobile phone 30 functions to determine whether the received data is music data or advertisement data. If the data is music data, the music data is output to ringtone melody setting section 304.
On the other hand, if the advertisement data is
The content is stored in the AM 312 and the content of the advertisement is displayed on the liquid crystal display 32. Thereby, the advertisement data received from the computer 10 is recorded in the mobile phone 30 and an advertisement can be displayed for the user.
