JP 2005-266302 A JP 2002-258840 A

  However, among the above-described conventional electronic musical instruments, in the former, various services from the server are provided in a uniform language regardless of which language is understandable by the user. For example, if the server to be accessed is in Japan, this electronic musical instrument is provided with various services in Japanese from that server. If the server to be accessed is in the United States, this electronic musical instrument is provided with various services in English from that server. Had been provided. Therefore, when downloading music data from the server, if an English-speaking user uses this electronic instrument to access a server in Japan, the song name of the song data is displayed in Japanese or the electronic instrument is displayed. Depending on the ability (that is, the model that cannot display Japanese characters), the song name of the song data could not be displayed.

  Of the above-described conventional electronic musical instruments, the latter is not linked to a server, and therefore cannot provide various services in a predetermined language from the server.

  The present invention has been made paying attention to this point, and provides an electronic musical instrument that can receive provision of various services from a server in a language intended by the user, and a program for realizing a control method thereof The purpose is to do.

To achieve the above object, the electronic musical instrument according to claim 1 requests connection data connected to a server via a communication network, and response data displayed in a natural language from the server connected by the connection means. Transmitting means for transmitting a request message to be received; and receiving means for receiving response data displayed in a natural language transmitted by the server via the communication network in response to the request message transmitted by the transmitting means. And the transmission means adds, to the request message, language designation information for designating the types of natural languages by giving priority to a plurality of types of natural languages, and the response data can be transmitted by the server among types of natural language, this is what is displayed in a natural language topmost in priority among types of natural language has been added to the request message The features.

  More preferably, it further has a determining means for determining the priority order.

  Preferably, the response data received by the receiving means includes language information, and the display mode is changed according to the language information to display the display information included in the received response data. It further has a display means.

In order to achieve the above object, the program according to claim 4 can be realized by the same technical idea as claim 1.

According to the first or fourth aspect of the present invention, when a request message for requesting response data displayed in a natural language is transmitted to a server connected by the connection means, a plurality of types of natural messages are included in the request message. since the language designation information designating a type of the natural language prioritize language is added, the server, natural language counterpart electronic musical instrument for transmitting the response data is required to understand with a priority, itself Of the natural languages that can be transmitted, response data displayed in the highest natural language in the priority order is transmitted. This makes it possible to receive various services from the server in the language intended by the user.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a schematic configuration of an electronic musical instrument according to an embodiment of the present invention.

  As shown in the figure, the electronic musical instrument of the present embodiment includes a performance operator 1 including a keyboard for inputting pitch information, and a setting including a plurality of switches, wheels, and joysticks for inputting various information. A detecting circuit 3 for detecting the operating state of the operating element 2, the operating element 1, a detecting circuit 4 for detecting the operating state of the setting operator 2, and a DIP (Dual Inline Package) switch used for factory setting 5, a CPU 6 that controls the entire apparatus, a ROM 7 that stores a control program executed by the CPU 6 and various table data, a RAM 8 that temporarily stores music data, various input information, calculation results, and the like, Timer 9 that measures interrupt time and various times in timer interrupt processing, and displays various information, such as a liquid crystal display (LCD) and a light emitting diode (L ED), a non-volatile memory 11 for storing various settings including language settings, an external storage device 12 for storing various application programs including the control program, various music data, various data, and the like. For example, a server computer (hereinafter abbreviated as “server”) is connected via a MIDI interface (I / F) 13 for inputting a MIDI message from the outside or outputting a MIDI message to the outside, and the communication network 101. ) Communication interface (I / F) 14 for transmitting and receiving data to and from 102, a tone generator circuit 15 for converting performance data input from the performance operator 1, preset music data, and the like into audio signals, and the tone generator circuit An effect circuit 16 for applying various effects to the audio signal from 15; Converting the audio signal from the circuit 16 to the acoustic, e.g., DAC (Digital-to-Analog Converter) or amplifier is constituted by a sound system 17 such as a speaker.

  The components 3 to 16 are connected to each other via a bus 18, a timer 9 is connected to the CPU 6, another MIDI device 100 is connected to the MID II / F 13, and a communication network 101 is connected to the communication I / F 14. Are connected to the sound source circuit 15, and a sound system 17 is connected to the effect circuit 16. Here, the communication I / F 14 and the communication network 101 are not limited to the wired system but may be a wireless system. In addition, both types may be provided.

  The DIP switch 5 is a switch made up of a plurality of small switches. As will be described later with reference to FIG. When the power of the electronic musical instrument of the present embodiment is turned on after setting is set to a predetermined pattern, the electronic musical instrument of the present embodiment is initialized to a factory shipment state corresponding to the set on / off pattern.

  Examples of the non-volatile memory 11 include an NV (Non Volatile) RAM, a power backed-up RAM, a flash memory, and the like. The nonvolatile memory 11 stores settings that should be retained even when the electronic musical instrument according to the present embodiment is turned off. This type of setting includes the current language setting, user ID, and the like. Note that the electronic musical instrument of the present embodiment is configured to be able to display characters in multiple languages. When any one of the languages is selected and set by user settings or factory settings, the characters in that language are displayed. Is displayed. Information on languages that can be handled by the electronic musical instrument of the present embodiment is stored in the ROM 7. Then, information indicating which language is currently set among the compatible languages, that is, the current language setting is stored in the nonvolatile memory 11.

  Examples of the external storage device 12 include a flexible disk drive (FDD), a hard disk drive (HDD), a CD-ROM drive, and a magneto-optical disk (MO) drive. As described above, the external storage device 12 can also store a control program to be executed by the CPU 6. If the control program is not stored in the ROM 7, the control program is stored in the external storage device 12. By reading it into the RAM 8, it is possible to cause the CPU 6 to perform the same operation as when the control program is stored in the ROM 7. In this way, control programs can be easily added and upgraded.

  As can be seen from the above configuration, the present invention is applied to an electronic keyboard instrument. However, the embodiment is not limited to a keyboard instrument, and may be a string instrument type, a wind instrument type, a percussion instrument type, or the like.

  The control process executed by the electronic musical instrument configured as described above will be described first with reference to FIG. 2 and then in detail with reference to FIGS.

  FIG. 2 is a diagram showing an example of a language setting screen displayed on the display device 10 when the language setting mode is selected. In FIG. 2, a plurality of operators 2a included in the setting operator 2 are shown. ˜2 g is also described.

  Each time the user operates one of the left / right movement switches 2e, 2f or the dial switch 2g, the languages that can be handled by the electronic musical instrument of this embodiment are switched and displayed. FIG. 2A shows a language setting screen 10a when English is selected as a compatible language, and either the left / right movement switch 2e, 2f or the dial switch 2g is operated on the language setting screen 10a. Then, the language setting screen 10a is switched to the Japanese language setting screen 10a ′ as shown in FIG. In the language setting screens 10a and 10a ′, an item enclosed in parentheses ([]) means that it can be set by a switch adjacent to the item, in the illustrated example, the switch 2c. For example, when the switch 2c is operated on the language setting screen 10a of FIG. 2A, the current language setting is determined to be “ENGLISH”, and the current language setting of the nonvolatile memory 11 is determined based on the determined language setting. The language setting is updated (rewritten).

  When the electronic musical instrument of the present embodiment accesses the server 102 and requests provision of various services, the current language setting is also transmitted to the server 102 together with this request. Thereby, the server 102 can know the current language setting of the electronic musical instrument of the other party (the electronic musical instrument of the present embodiment) that provides the service, and therefore provides the service corresponding to the language to the electronic musical instrument of the other party. Can do.

  Next, this control process will be described in detail.

  FIG. 3 is a flowchart showing the procedure of the language setting process executed by the electronic musical instrument of the present embodiment, particularly the CPU 6.

  This language setting process is started when the user selects a language setting mode using, for example, a mode switch (not shown) in the setting operator 2 or the operators 2a to 2g.

  When the language setting process is started, first, the CPU 6 acquires a language that can be supported by the electronic musical instrument of the present embodiment from the ROM 7 (step S1). As described above, the electronic musical instrument of the present embodiment is configured to support multiple languages, and the types of languages that can be supported are stored in the ROM 7, so in step S1, the types of the languages are stored. Get information about. Note that although two types of languages, English and Japanese, can be handled by the electronic musical instrument of the present embodiment, this is merely for convenience of explanation, and there may be more than this.

  Next, the CPU 6 acquires the current language setting from the nonvolatile memory 11 (step S2). The initial value of the language setting is set by the factory setting (refer to FIG. 4) made at the time of factory shipment. If the language setting process is started for the first time after the electronic musical instrument of the present embodiment is shipped from the factory, the language setting stored in the nonvolatile memory 11 is an initial value at the time of factory shipment.

  Next, the CPU 6 first displays the current language setting acquired in step S <b> 2 on the display device 10. Assuming that Japanese is set as the current language setting, the language setting screen 10a ′ of FIG. 2 is displayed on the display device 10, and assuming that English is set as the current language setting, On the display device 10, the language setting screen 10a of FIG. Then, when the user selects one of these two languages (step S3), that is, when the user operates the switch 2c with either of the language setting screens 10a or 10a 'displayed. The language setting of the nonvolatile memory 11 is rewritten in the selected language (step S4).

  FIG. 4 is a flowchart showing the procedure of the factory setting process.

  The factory setting process is started when the power source of the electronic musical instrument according to the present embodiment is turned on after the DIP switch 5 is set to a predetermined on / off pattern.

  First, the CPU 6 reads the on / off state of the DIP switch 5, and determines the language according to the read on / off state (on / off pattern) (step S11).

  Next, the CPU 6 updates the language setting of the nonvolatile memory 11 with the determined language (step S12).

In addition to language settings, various settings are stored in the non-volatile memory 11, and the settings are determined according to the on / off pattern of the DIP switch 5 (setting state at the time of factory shipment) (Step S13) . As other settings, as described above, there is a user ID, but the user ID is registered by the user and is not registered at the time of shipment from the factory. Therefore, the user ID is registered in the nonvolatile memory 11. If the user ID has been set, the user ID is deleted by the factory setting process.

  In this way, in the factory setting process, the setting contents of the nonvolatile memory 11 can be set to the intended factory shipment state by appropriately changing the on / off pattern of the DIP switch 5. For example, when the destination of the electronic musical instrument targeted for factory setting is the United States, the language setting of the nonvolatile memory 11 is set to English by the factory setting process.

  FIG. 5 is a flowchart showing a procedure of information transmission / reception processing with the server executed by the electronic musical instrument of the present embodiment, particularly the CPU 6.

  The transmission / reception process of this information is started when the user gives an instruction to acquire necessary information from the server 102 using the setting operator 2, for example.

First, the CPU 6 determines the content provided from the server 102 (data content received from the server 102) (step S21) . An example of the provided contents is a song name of song data distributed by the server 102. In the transmission / reception process of this information, an example in which a song title of song data is received from the server 102 and displayed on the display device 10 will be described.

  Next, the CPU 6 obtains a language that can be supported by the electronic musical instrument of the present embodiment from the ROM 7 (step S22) and performs the current operation from the nonvolatile memory 11 in the same manner as in steps S1 and S2 of FIG. Language setting is acquired (step S23).

  Next, the CPU 6 determines a method for receiving the provision from the provision contents determined in the step S21, and determines language information from the acquired compatible language and the current language setting. A request header including the determined method and language information is generated (step S24). In this embodiment, since data is transmitted to and received from the server 102 using HTTP (Hypertext Transfer Protocol), a request is sent from the client (electronic musical instrument of this embodiment) to the server (server 102). When transmitting, an instruction called an HTTP method is used. Therefore, during the process of step S24, the method determination means determination of which method to use from a plurality of types of methods. In the present embodiment, the language information described in the request header is listed with priority. Specifically, the current language setting is listed at the top, the highest priority is given, and other languages, that is, the remaining languages obtained by removing the language of the current language setting from the corresponding languages acquired in step S22. Are listed with a lower priority. When there are a plurality of remaining languages (in this embodiment, there are only two types of supported languages, this is not the case), there is a problem of how to prioritize the remaining languages. However, for example, the same priority may be assigned so that it is left to the server 102 to prioritize, or the closer to the top, the higher the priority may be. Note that there may be only one language information described in the request header, and the language of the current language setting may be described.

  FIG. 6 is a diagram illustrating an example of a part of the generated request header.

  As shown in the figure, the request header includes method, host, and language information. The request header actually includes other data, but the other data is not shown because it is not necessary for describing the features of the present invention.

  In this embodiment, in order to receive the song name of the song data from the server 102, the GET method is described in the method field. In the GET method, the song name (songname1) is designated as a resource, and the acquisition is hosted. To request. In the host field, the URL (uniform resource locator) of the server 102 is described. Furthermore, “Accept-Language: ja, en” is described in the language information field. Here, “ja” indicates Japanese, and “en” indicates English. Since “ja” is written at the top and “en” is written after that, “ja” has a higher priority than “en”. Accordingly, the server 102 first tries to provide the requested service in Japanese, and when the service cannot be provided in Japanese (for example, when there is no Japanese song title), the requested service in English. To provide. If the requested service cannot be provided in both languages, the server 102 can provide the requested service in the higher priority (first) language or a language close to that language. Make a provision. It should be noted that the request header is generated as a request for the data content desired to be provided from the server 102. The data request using the GET method can be performed only by the header, and the body is required. Because it does not. Therefore, depending on the type of data to be provided from the server 102, the header alone may not be sufficient and a body may be required.

The request header generated in this manner, CPU 6 via the communication I / F14 and the communication network 101, to the server 102 that are specified as the host (step S25).

  The server 102 responds to the received request header (in this embodiment, linguistic information (for example, SHIFT-JIS) indicating that it is in Japanese and song name data (for example, SHIFT-JIS) written in Japanese). Data including JIS code character string data) is transmitted to the electronic musical instrument of the present embodiment via the communication network 101. The electronic musical instrument of the present embodiment receives this response data (step S26), extracts the language information included in the received response data, and determines the display mode (step S27). Here, the determination of the display mode is a case where response data including language information different from the current language setting is received, and the electronic musical instrument of the present embodiment can display the display information of the different language information (that is, In the case where the language of the different language information is one of the languages that the electronic musical instrument of the present embodiment is compatible with), the font used for displaying the display information in the language of the different language information Means changing to a corresponding one. Therefore, when response data including language information in the same language as the language of the current language setting is received, “determination of display mode” is usually not necessary. Specific examples of language information included in the response data include ASCII, Latin-1 (ISO8859-1), SHIFT-JIS, EUC-KR, UCS-2, and UTF-8.

  Then, the display information (in this embodiment, song name data) included in the received response data is extracted and displayed (step S28).

  In this information transmission / reception process, the song name of the song data is received from the server 102 and displayed, but the provided song name is stored in the nonvolatile memory 11 without being displayed. Alternatively, the song data may be provided together with the song name, the song name may be displayed, and the song data may be automatically reproduced.

  Thus, in this embodiment, language information is added to a request message for requesting provision to the server (in this embodiment, it is a request header but may not be a header). When the service is provided to the electronic musical instrument according to the present embodiment, the language of the service can be designated, thereby improving the operability of the electronic musical instrument according to the present embodiment.

  In addition, a plurality of prioritized language information is added as language information, and the server provides a service in a language according to the priority, so that the received service is not garbled. The operability of the electronic musical instrument of the present embodiment is further improved.

  In the present embodiment, the language information set by the factory setting can be freely changed by the user setting (the language setting process in FIG. 3). However, the present invention is not limited to this, and is set by the factory setting. Thereafter, the language information may not be freely changed by the user. However, even in this case, when the electronic musical instrument is compatible with a plurality of languages, the language information described in the request header is a plurality of language information with priorities assigned in the same manner as in the present embodiment. When the server provides a service in a language that is not the highest priority (a language different from the language information language set by the factory settings), the display mode according to the language is determined and provided in this display mode. The displayed service may be displayed. In this case, the language information described in the request header may be only language information set by factory settings.

  In this embodiment, transmission / reception of data with the server is performed using HTTP, but other protocols may be used. However, when requesting a service using HTTP, language information is transmitted to the server side every time, so even if the language setting of the electronic musical instrument is changed during the service, it is provided from the server side. The language of the service can correctly follow the change of the language setting on the electronic musical instrument side. Of course, even if other protocols are adopted, when the service is requested, if the language information is transmitted to the server each time, the electronic musical instrument in the middle of the service can be used as in the case of using HTTP. The server side can follow the change of the language setting correctly.
