Japanese Patent No. 4735544

By the way, conventionally, when a user makes a mistake in performance operation, there is a case where a singing sound cannot be output at an appropriate pitch. For example, in keyboard performance, a plurality of keys may be operated due to a user's mistouch and a plurality of pitches may be designated. In this case, since a singing sound is output at the pitch of each of the operated keys, there is a possibility that a mistouch is clearly recognized by the audience. Therefore, it is desired to output a singing sound with an appropriate pitch even when a plurality of pitches are designated by a performance operation.
For example, as in the technique described in Patent Document 1, when lyrics data is determined in advance, lyrics are sequentially read according to each operation. Therefore, when a plurality of keys are operated due to a user's mistouch, the lyrics may be read out unintentionally.

  Some embodiments of the present invention provide a sound generation control device, a sound generation control method, and a program capable of outputting a sound of a specific syllable at an appropriate pitch with respect to an input designating a plurality of pitches. One of the purposes.

  Another object of another aspect of the present invention is to provide a sound generation control device, a sound generation control method, and a program that can achieve the effects described in the embodiments described later.

  In order to solve the above-described problem, one aspect of the present invention includes a syllable acquisition unit that acquires syllable information indicating one syllable of a sound to be generated, and a plurality of operation reception units each corresponding to one pitch. An input unit including a plurality of operation reception units arranged spatially, and a selection unit for selecting one pitch from a plurality of pitches corresponding to the operated operation reception units. And an output control unit that outputs the sound of one syllable indicated by the syllable information acquired by the syllable acquisition unit from the output unit at a pitch selected by the selection unit.

  According to the embodiment of the present invention, it is possible to output a sound of a specific syllable at an appropriate pitch with respect to an input designating a plurality of pitches.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[First embodiment]
A first embodiment of the present invention will be described. First, an outline of the present embodiment will be described.
The sound generation control device according to the present embodiment is an electronic musical instrument 1 that performs singing simulation in response to an operation on a performance operator. Here, singing simulation means simulating singing by outputting a sound simulating a human voice. FIG. 1 is a diagram illustrating an example of a performance operator 15 provided in the electronic musical instrument 1. FIG. 1 shows a case where a keyboard is applied as the performance operator 15. A plurality of white keys and black keys are arranged side by side on this keyboard, and each key is associated with a different pitch. When playing the electronic musical instrument 1, the user presses a desired key on the keyboard. The electronic musical instrument 1 detects a key operated by the user and generates a singing sound having a pitch corresponding to the operated key. Note that the order of syllables of the singing sounds to be generated is predetermined.

Here, a plurality of keys are spatially arranged on the keyboard. For this reason, the user may make a mistake in the operation position at the time of performance, and may press a key adjacent to the desired key simultaneously with the desired key or alone. For example, when trying to press the white key 151 shown in FIG. 1, the adjacent black key 152 or white key 153 may be erroneously pressed. In the case of such an erroneous operation (mistouch), the user generally presses the desired white key 151 again or shifts his / her finger from the erroneously operated key so that only the white key 151 is pressed. Try to correct the operation. Therefore, the electronic musical instrument 1 determines the occurrence of such an erroneous operation and a key that the user originally wanted to operate (hereinafter referred to as “desired key”), and sings at a pitch corresponding to the desired key. Is output. Thereby, the electronic musical instrument 1 can output the singing sound at an appropriate pitch desired by the user at the beginning.
The above is the description of the outline of the present embodiment.

  Next, the configuration of the electronic musical instrument 1 will be described. FIG. 2 is a block diagram illustrating an example of the configuration of the electronic musical instrument 1. The electronic musical instrument 1 includes a CPU (Central Processing Unit) 10, a timer 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a data storage unit 14, a performance operator 15, and parameter values. A setting operator 17, a display unit (display device) 18, a sound source 19, an effect circuit 20, a sound system 21, a communication I / F (Interface), and a bus 23 are provided.

  The CPU 10 is a central processing unit that controls the entire electronic musical instrument 1. The timer 11 is a module that measures time. The ROM 12 is a non-volatile memory that stores control programs and various data. The RAM 13 is a volatile memory used as a work area for the CPU 10 and various buffers. The data storage unit 14 stores lyrics text data, phonological information database, and the like. Lyric text data is data describing the lyrics. In the lyrics text data, the lyrics for each song are described in syllable units. A syllable is a group of sounds output in response to one performance operation. The phoneme information database is a database that stores speech segment data. The speech segment data is data indicating a speech waveform, and includes, for example, spectrum data of a sample sequence of speech segments as waveform data. Further, the speech unit data includes unit pitch data indicating the pitch of the waveform of the speech unit. Lyric text data and speech segment data may be managed by a database. The display unit 18 is a display module such as a liquid crystal display panel or an organic EL (Electro-Luminescence) panel. The display unit 18 displays an operation state of the electronic musical instrument 1, various setting screens, a message for the user, and the like.

  The performance operator 15 is a module that receives a performance operation for designating a pitch. In the present embodiment, as an example, a case where the performance operator 15 is a keyboard will be described. The performance operator 15 outputs performance information such as note-on / note-off based on the on / off of the sensor corresponding to each key, and the strength (speed, velocity) of key depression. This performance information may be in a MIDI (musical instrument digital interface) message format. The other operation elements 16 are operation modules such as operation buttons and operation knobs for performing settings other than performance, such as settings related to the electronic musical instrument 1, for example. The parameter value setting operator 17 is an operation module such as operation buttons and operation knobs for setting parameters for the attributes of the singing sound. Parameters include, for example, harmonics, brightness, resonance, and gender factor. Harmonic is a parameter that sets the balance of overtone components contained in the voice. Brightness is a parameter for setting the contrast of a voice and gives a tone change. Resonance is a parameter for setting the tone color and strength of a colored sound. The gender element is a parameter for setting a formant, and changes the voice thickness and texture in a feminine or masculine manner.

The sound source 19 is a module having a plurality of sound generation channels. One tone generation channel is assigned to the sound source 19 according to the performance of the user under the control of the CPU 10. The sound source 19 reads out the speech segment data corresponding to the performance from the data storage unit 14 and generates singing sound data in the assigned sound generation channel. The effect circuit 20 applies the acoustic effect specified by the parameter value setting operator 17 to the singing sound data generated by the sound source 19. The sound system 21 converts the singing sound data processed by the effect circuit 20 into an analog signal by a digital / analog converter. And the sound system 21 amplifies the singing sound converted into the analog signal, and outputs it from a speaker. The communication I / F 22 is a communication module that communicates with an external device of the electronic musical instrument 1. The external storage device 3 is an external device of the electronic musical instrument 1, for example, and is a device that stores audio data, for example. The bus 23 is a bus for transferring data between the units in the electronic musical instrument 1.
The above is the description of the configuration of the electronic musical instrument 1.

Next, the operation of the electronic musical instrument 1 will be described.
FIG. 3 is a flowchart showing an example of the flow of processing when a performance by the electronic musical instrument 1 is performed.
Here, processing when the user performs selection of a performance song and performance of the selected song will be described. In addition, here, in order to simplify the description, a case will be described in which only a single sound is output even when a plurality of keys are operated simultaneously. In this case, only the highest pitch among the pitches of keys operated simultaneously may be processed, or only the lowest pitch may be processed. Note that the processing described below is realized, for example, when the CPU 10 executes a program stored in the ROM 12 or the RAM 13 and functions as a control unit that controls various configurations of the electronic musical instrument 1.

  First, the electronic musical instrument 1 receives an operation for selecting a song to be played from the user (step S10). When the electronic musical instrument 1 accepts selection of a song, the electronic musical instrument 1 reads lyrics text data of the selected song. Then, the electronic musical instrument 1 sets the cursor position at the first syllable described in the lyric text data (step S12). Here, the cursor is a virtual index indicating the position of the next syllable to be pronounced.

  Next, the electronic musical instrument 1 determines whether or not note-on is detected (step S14). When note-on is not detected (step S14: NO), the electronic musical instrument 1 determines whether or not note-off is detected (step S22). When note-on is detected in step S14 (step S14: YES), that is, when a new key press is detected, the electronic musical instrument 1 stops outputting sound when outputting sound ( Step S16). Next, the electronic musical instrument 1 executes an output sound generation process for generating a singing sound according to note-on (step S18). The output sound generation process will be described later. Next, the electronic musical instrument 1 updates the cursor position (reading position) (step S20), and determines whether or not note-off is detected (step S22).

  Here, determination of the cursor position and pronunciation of the singing sound according to the processes of steps S18 and S20 will be described using a specific example. First, the update of the cursor position will be described. FIG. 4 is a diagram illustrating an example of lyrics text data. In the example of FIG. 4, lyrics of five syllables c1 to c5 are described in the lyric text data. Each character “ha”, “ru”, “yo”, “ko”, “i” indicates one character of Japanese hiragana, and each character corresponds to one syllable. The electronic musical instrument 1 updates the cursor position in syllable units. For example, when the cursor is positioned at the syllable c3, the speech segment data corresponding to “yo” is read from the data storage unit 14 and the singing sound of “yo” is pronounced. When the electronic musical instrument 1 finishes pronunciation of “yo”, the electronic musical instrument 1 moves the cursor position to the next syllable c4. In this way, the electronic musical instrument 1 sequentially moves the cursor position to the next syllable in response to note-on.

Next, the pronunciation of the singing sound will be described. FIG. 5 is a diagram illustrating an example of the type of speech segment data. The electronic musical instrument 1 extracts speech segment data corresponding to the syllable from the phonological information database in order to pronounce the syllable corresponding to the cursor position. There are two types of speech segment data: phoneme chain data and stationary partial data. The phoneme chain data is data indicating a speech segment when the pronunciation changes, such as “silence (#) to consonant”, “consonant to vowel”, “vowel to consonant (vowel of the next syllable)”. . The stationary partial data is data indicating a speech unit when the vowel sound continues. For example, when the cursor position is set to “ha (ha)” of the syllable c1, the sound source 19 includes the speech chain data “# -h” corresponding to “silence → consonant h” and “consonant h → vowel a”. Is selected from the speech chain data “ha” corresponding to “” and the stationary partial data “a” corresponding to “vowel a”. When the electronic musical instrument 1 starts playing and detects a key depression, the electronic musical instrument 1 operates the singing sound based on the voice chain data “# -h”, the voice chain data “ha”, and the steady partial data “a”. Output with the pitch according to the key and the velocity according to the operation.
This completes the description of the determination of the cursor position and the pronunciation of the singing sound.

Returning to FIG. 3, the description will be continued. When note-off is not detected in step S22 (step S22: NO), the electronic musical instrument 1 determines whether or not the performance is finished (step S26). In addition, when note-off is detected in step S22 (step S22: YES), the electronic musical instrument 1 stops outputting sound (step S24) if it is outputting sound. Then, the electronic musical instrument 1 determines whether or not the performance is finished (step S26).
If it is determined in step S26 that the performance has ended (step S26: YES), the electronic musical instrument 1 stops outputting the sound if it is outputting a sound (step S28). And the electronic musical instrument 1 complete | finishes the process shown in FIG. If it is determined in step S26 that the performance has not ended (step S26: NO), the electronic musical instrument 1 returns the process to step S14. Note that whether or not the performance has ended is determined, for example, whether or not the cursor position has moved to the last syllable, whether or not an operation for ending the performance has been performed by the other operator 16, or the like. Can be done.
In the example shown in FIG. 3, the case where the sound being output is stopped at the time of note-off has been described. However, the electronic musical instrument 1 may read and output a syllable that is different from the syllable that is additionally output at the time of note-off. Good.
The above is the description of the flow of processing when a performance by the electronic musical instrument 1 is performed.

Next, the operation of the electronic musical instrument 1 in step 18 will be described. FIG. 6 is a flowchart illustrating an example of the flow of output sound generation processing.
First, the electronic musical instrument 1 calculates a mistouch determination timing based on the note-on detection timing (step S30). That is, the electronic musical instrument 1 sets a mistouch determination period. The mistouch determination period is a period provided for determination of an erroneous operation, and is a period from a note-on detection timing to a mistouch determination timing. If an operation for designating a plurality of pitches is performed within the mistouch determination period, the electronic musical instrument 1 determines that a mistouch has occurred. The mistouch determination period is set as a period from the detection of note-on to the elapse of a predetermined time length. The predetermined time length may be described as an absolute time measured on the time axis of the timer 11 such as 100 milliseconds, or relative to the tempo of the song such as a 16th note length or a 32nd note length. May be described in a typical time.

  Next, the electronic musical instrument 1 reads out the speech segment data (waveform data) of the syllable corresponding to the cursor position (step S32). Next, the electronic musical instrument 1 outputs a sound having a waveform indicated by the read speech segment data at a pitch corresponding to the operated key (step S34). Specifically, the difference between the pitch indicated by the unit pitch data included in the speech unit data and the pitch corresponding to the operated key is obtained, and the spectrum distribution indicated by the waveform data by the frequency corresponding to this difference is obtained. Is moved in the frequency axis direction. Thereby, the electronic musical instrument 1 can output a singing sound with the pitch corresponding to the operated key. Next, the electronic musical instrument 1 secures a performance information storage area in the RAM 13 or the data storage unit 14 (step S36). The performance information storage area is a storage area for accumulating performance information performed during the mistouch determination period. Next, the electronic musical instrument 1 stores the performance information related to note-on detected in the process of step S14 in the performance information storage area (step S38). Next, the electronic musical instrument 1 determines whether or not the mistouch determination timing has arrived (step S40). If the mistouch determination timing has not arrived (step S40: NO), the electronic musical instrument 1 determines whether or not note-on or note-off is newly detected (step S42). When note-on or note-off is newly detected (step S42: YES), the electronic musical instrument 1 stores the performance information related to the detected note-on or note-off in the performance information storage area (step S44). When note-on or note-off is not newly detected in the process of step S42 (step S42: NO), the electronic musical instrument 1 returns the process to step S40.

  Further, in the process of step S40, when the mistouch determination timing has arrived (step S40: YES), the electronic musical instrument 1 should immediately stop outputting the sound based on the performance information stored in the performance information storage area. Is determined (step S46). Specifically, the electronic musical instrument 1 determines that sound output should be stopped immediately when there is no note-on key. If it is determined that the sound output should be stopped immediately (step S48: YES), the electronic musical instrument 1 stops the sound output (step S50). Thereafter, the electronic musical instrument 1 ends the process shown in FIG. 6 and advances the process to step S20 described above. If it is not determined in step S48 that the sound output should be stopped immediately (step S48: NO), the electronic musical instrument 1 outputs based on the performance information stored in the performance information storage area. A pitch to be detected is detected and selected (step S52).

Here, the selection of the pitch to be output by the electronic musical instrument 1 will be specifically described. In general, a plurality of patterns are assumed to correct mistouch during performance. Here, as an example, the first pattern and the second pattern will be described.
In the first pattern, when a desired key (for example, C3) is operated and another key (for example, D3) is operated, or when a desired key is operated, an adjacent key and a desired key are simultaneously operated. This is a correction method in the case of operation. In order to correct mistouch, it is assumed that the user cancels the first operation (note-on) in a short time (note-off) and operates the desired key again (note-on). Then, after operating the desired key, the user should maintain the operation for a desired length of time. Therefore, the electronic musical instrument 1 refers to the performance information stored in the performance information storage area, and when note-off is detected in a short time from the first note-on, the key on which the last note-on was detected is detected. Is determined to be a desired key. Then, the electronic musical instrument 1 selects a pitch (for example, C3) corresponding to the desired key as a pitch to be output.

The second pattern is another example of a correction method in a case where an adjacent key (for example, D3) and a desired key are operated simultaneously while attempting to operate a desired key (for example, C3). In order to correct a mistouch, it is assumed that the user cancels only the erroneous operation (note off) while maintaining the operation on the desired key among the operations performed on the two keys performed first (note on). Therefore, the electronic musical instrument 1 refers to the performance information stored in the performance information storage area, and when the first note-on is simultaneously detected for a plurality of keys, the electronic musical instrument 1 desires the key that has been kept on until the end. It is determined that it is a key. Then, the electronic musical instrument 1 selects a pitch (for example, C3) corresponding to the desired key as a pitch to be output.
It is assumed that it is rare to operate a key that is spatially separated from a desired key in a mistouch. Therefore, the operation to be determined for mistouch may be limited to the operation of the adjacent key. In this case, a non-adjacent key operation may be treated as a newly performed normal operation. That is, the operation of the separated key may be handled as the operation detected in step S14. The above-described method for determining the desired key is an example, and the electronic musical instrument 1 may determine the desired key by referring to arbitrary information such as note-on, note-off, and velocity included in the performance information.
This completes the description of the selection of the pitch to be output by the electronic musical instrument 1.

Returning to FIG. 6, the description will be continued. After the process of step S52, the electronic musical instrument 1 determines whether or not the pitch being output should be adjusted (step S54). Specifically, it is determined whether or not the pitch output in step S34 matches the pitch selected in step S54. If it is determined that the pitch being output should not be corrected (step S54: NO), the electronic musical instrument 1 ends the process shown in FIG. 6 and proceeds to the above-described step S20. If it is determined that the pitch of the sound being output should be corrected (step S54: YES), the electronic musical instrument 1 changes the pitch of the sound being output to the pitch detected in the process of step S52. (Step S56). At this time, the electronic musical instrument 1 changes the pitch by a pitch shift. In the pitch shift, the spectrum distribution indicated by the waveform data is moved in the frequency axis direction by the frequency corresponding to the pitch difference to be shifted. The electronic musical instrument 1 may change the pitch in stages, for example, in units of 20 cents.
The above is the description of the output sound generation process.

  Conventional electronic musical instruments that output singing sounds include musical instruments that output only single singing sounds. In such an instrument, when a plurality of keys are pressed at the same time, a singing sound is output at the pitch of the key pressed first, and a singing sound is output at the pitch of the key pressed last. May be. In the former case, the subsequent operation is invalidated while the first key depression is not released. Therefore, for example, in the case of the second pattern, once an erroneously operated key is validated, the operation of the desired key is invalidated even if the operation is canceled. Cannot output singing sound at high. In the latter case, since the operation is always enabled, all operations for correcting the erroneous operation are reflected in the singing sound. Further, in the case where predetermined lyrics are read according to the performance, all of the erroneous operation correction operations are reflected in the reading of the lyrics. That is, if an erroneous operation occurs, the lyrics before the lyrics originally intended by the user are read out, and the performance fails.

  On the other hand, the electronic musical instrument 1 according to this embodiment has a syllable acquisition unit (for example, the CPU 10) that acquires syllable information (for example, information on the syllable at the cursor position in the lyrics text data) indicating one syllable of the sound to be generated. ) And a plurality of operation reception units (for example, keys) each corresponding to one pitch, and a plurality of operation operators 15 including a plurality of operation reception units arranged spatially, and a plurality of operated operation reception units 15 A selection unit (for example, the CPU 10) that selects one pitch from a plurality of pitches corresponding to the operation reception unit, and a syllable sound indicated by the syllable information acquired by the syllable acquisition unit, It has a function of an output control unit (for example, CPU 10) that outputs from the output unit (for example, sound system 21) at the pitch selected by the selection unit.

  Thereby, even when a plurality of pitches are designated, the electronic musical instrument 1 selects any one of them and outputs a singing sound at the selected pitch. That is, the electronic musical instrument 1 outputs a specific syllable sound at an appropriate pitch in response to an input designating a plurality of pitches. Therefore, for example, even if the user makes a miss-touch during performance, the pitch of the singing sound does not fluctuate according to the note-on or note-off of the mis-touch. And the electronic musical instrument 1 can produce so that a singing sound may be connected naturally.

The output control unit outputs the sound of one syllable indicated by the syllable information acquired by the syllable acquisition unit from the output unit at a first pitch, and then selects the second selected by the selection unit. Change to the pitch of and output.
Thereby, for example, the electronic musical instrument 1 starts outputting the singing sound at a timing when the first operation is performed, that is, at a timing before the determination of the desired key is confirmed after a mistouch is performed. When the determination of the desired key is confirmed, the pitch of the singing sound is changed to a pitch corresponding to the desired key. Thereby, the electronic musical instrument 1 can output the singing sound without causing a time lag from the operation. In addition, the electronic musical instrument 1 corrects the pitch in a short time without muting the sound without changing the syllable (ie, lyrics) to be generated in response to a mistouch. Therefore, it is difficult for the electronic musical instrument 1 to feel that there has been a mistouch in terms of hearing.

The output control unit selects one pitch when a plurality of the operation receiving units spatially adjacent to each other are operated.
Thereby, the electronic musical instrument 1 is set as a mistouch determination target when, for example, a spatially adjacent key is operated. There is a high probability that a mistouch will occur for an adjacent key. Therefore, the electronic musical instrument 1 can improve the determination accuracy of mistouch and appropriately determine whether or not the pitch adjustment is necessary.

The output control unit selects one pitch when the second operation receiving unit is operated within a predetermined period (for example, a mistouch determination period) after the first operation receiving unit is operated.
Accordingly, the electronic musical instrument 1 is set as a mistouch determination target only when a plurality of operations are performed within a predetermined period, for example. The mistouch correction operation is likely to be performed within a short time. Therefore, the electronic musical instrument 1 can improve the determination accuracy of mistouch and appropriately determine whether or not the pitch adjustment is necessary.
For example, if the mistouch determination period is set to a short period of about 32nd note length and the mistouch determination target is limited to adjacent keys, the electronic musical instrument 1 adjusts the pitch of 100 cents or 200 cents in a short period. Will do. Therefore, in this case, at the time when the sound is stably output, it is recognized by the human ear as a sound having only the pitch of the desired key. Therefore, the electronic musical instrument 1 can prevent the audience from recognizing that a mistouch has occurred during performance.

The syllable acquisition unit sequentially acquires the syllable information from a storage unit that stores a plurality of ordered syllable information according to the selection unit selecting one pitch from a plurality of pitches. To do.
Thereby, the electronic musical instrument 1 sequentially reads out predetermined lyrics according to the selection of the pitch, and generates a singing sound. Therefore, for example, even when the user performs a plurality of operations for correcting mistouch, the electronic musical instrument 1 can advance only one cursor position according to the plurality of operations. In other words, the electronic musical instrument 1 can prevent the correction operation for each mistouch from being reflected in the reading of the lyrics, so that the lyrics are not read out excessively.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above-described embodiment, and includes a design and the like within a scope not departing from the gist of the present invention. For example, each configuration described in the above embodiment can be omitted when it is not necessary to exhibit a specific function. Moreover, each structure demonstrated in the above-mentioned embodiment may be isolate | separated, and may be provided in a separate apparatus.

  In the embodiment described above, the case where the performance operator 15 is a keyboard has been described as an example. However, the performance operator 15 may have a shape in which strings are arranged side by side like a guitar. The performance operator 15 may be a keyboard, strings, or a plurality of buttons for pitch designation displayed on a touch panel. That is, the performance operator 15 only needs to have an operation receiving unit for inputting a plurality of different pitches arranged spatially. The touch panel is a display module and a touch sensor that are integrally configured to detect an operation on the display surface of the display module.

In the above-described embodiment, the syllable is sequentially read from the lyric text data. However, the syllable may be separately specified at the time of performance through the other operation element 16 or the like.
Moreover, although embodiment mentioned above demonstrated the aspect which outputs a single singing sound, the electronic musical instrument 1 may output a chord singing sound.
In the above-described embodiment, the case where the data in the MIDI format is handled has been described. However, the present invention is not limited to this. For example, the electronic musical instrument 1 may analyze sound data such as a microphone input and extract a sound generation timing and pitch.
In the embodiment described above, Japanese lyrics are exemplified, but the present invention is not limited thereto. In Japanese, one character is one syllable, but in other languages, one character often does not become one syllable. For example, if the English lyrics are “september”, the three syllables are “sep”, “tem”, and “ber”. In this case, every time the user operates the performance operator 15, the electronic musical instrument 1 sequentially generates each syllable at the pitch of the operated key. Thus, the lyrics are not limited to Japanese and may be in other languages.

  Further, the electronic musical instrument 1 is recorded by recording a program for realizing the functions of the electronic musical instrument 1 on a computer-readable recording medium, causing the computer system to read and execute the program recorded on the recording medium. You may perform the process of. Here, “loading and executing a program recorded on a recording medium into a computer system” includes installing the program in the computer system. The “computer system” here includes an OS and hardware such as peripheral devices. Further, the “computer system” may include a plurality of computer devices connected via a network including a communication line such as the Internet, WAN, LAN, and dedicated line. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. As described above, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM. The recording medium also includes a recording medium provided inside or outside that is accessible from the distribution server in order to distribute the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program that can be executed by the terminal device. That is, the format stored in the distribution server is not limited as long as it can be downloaded from the distribution server and installed in a form that can be executed by the terminal device. Note that the program may be divided into a plurality of parts, downloaded at different timings, and combined in the terminal device, or the distribution server that distributes each of the divided programs may be different. Furthermore, the “computer-readable recording medium” holds a program for a certain period of time, such as a volatile memory (RAM) inside a computer system that becomes a server or a client when the program is transmitted via a network.
