Description

SYSTEM FOR PROVIDING ELECTRONIC MUSICAL

SCORE

Technical Field

[1] The present invention relates to a system for providing an electronic musical score, and more particularly to a system for providing a digital musical score to a musician or a chorus. Background Art

[2] An orchestra, a chorus or the choir in church plays or sings with a musical score in a music stand or in hand. In case of employing the music stand, it needs to manually turn the musical score or to pedal the music stand so as to mechanically tune the musical score.

[3] In such a manner that the music score is turned manually with a hand or mechanically with a foot, it is difficult for a conductor, a musician or a chorus to concentrate on playing or singing while turning the musical score. Further, the paper or filed musical score is inconvenient for the choir or the chorus to hold it in his/her hand while singing. Also, if an assistant turns the musical score while a musician plays a musical instrument, it may look bad to the audience. Disclosure of Invention Technical Problem

[4] To solve the foregoing problems, an aspect of the present invention is to provide a system for efficiently offering a digital musical score or a function needed in playing or singing to a display device of a musician or a chorus. Technical Solution

[5] The foregoing and other aspects of the invention are achieved by providing a system for providing an electronic musical score, the system including: a main server which stores a digital musical score and controls the system; a user interface unit which receives informaiton or a command from the exterior, and displays the information or the command through a display module under control of the main server; a user display part which includes two or more display unit^'s and displsys information containing a musical score through the respective display units under control of a video distributor; and the video distributor which controls screens to be displayed on the respective display units under the control of the main server. [6] The main server may include: a memory to store the digital music score; and a controller to control the system.

[7] The controller may may include: a log-in controller which checks access authority to the system for providing the electronic musical score and approves access of an authenticated user a training controller which provides a function for training the successfully logged-in user a playing controller which provides a play list if the system for providing the electronic musical score is used in a practical play; and a managment controller which controls data about a musical score to be systematically managed.

[8] Thus, the system according to the present invention replaces a conventional paper musical score, and automatically provies the musical score to a member.

[9] The log-in controller may check the access authority according to levels of the access authority and groups of accessing, so that only a qualified constructor or a qualified musician can control the whole system.

[10] The training controller may calculate time to be taken in playing or singing one page of a musical score, and control a musical score automatic turning function to be performed for turning a page of a musical score displayed on the screen. At this time, the training controller may calculate a page time of the musical score by the following equation:

[11] [Equation]

[12] βOzxt Page! ime yv

[13] where, x is the number of bars; v is a reference note value for a metronom value; y is a metronom value; z is a musical time; and t is a reference note value for a musical time, in which t/v represents a ratio of the reference note values.

[14] The training controller may control a musical score mannual turning function to be performed for turning the page of the musical score when receiving a command of turning the page through the user interface unit.

[15] If the musical score is displayed on divided screens, the page of the musical score may be turned by maintaining a displaying place for a current page until the music score of the current page is completely played, and displaying a next page at a different place from the displaying place for the current page.

[16] If a memorandum is written on a currently display musical score, the training controller may control a memo function to be performed for storing and displaying the memorandum along with the musical score or storing and displaying the memorandum separately from the musical score. [17] The training controller may control the memory to store data which is recognized as characters by the user interface unit with respect to a memorandum written on the screen of the user display part, and a signal based on the stored data to be transmitted to the user display part. [18] Thus, the system for providing the electronic musical score according to the present invention proves the memo function, so that a conductor can write the memorandum on the musical score as necessary while singing or playing, and show this memorandum to all members or a certain member. [19] The controller may provide a recording function for storing sound input through a microphone in the main server, and the controller may provide a user display individual control function for controlling the screens of the respective display units constituting the user display part individually or in a group. Further, the controller may provide a musical score searching function for searching the musical scores digitally stored in the memory of the main server. [20] Also, the user interface unit may include: a display module; and an input/output interface module. [21] At this time, the display module may include a liquid crystal display (LCD) monitor provided with a touch screen function and a character recognition function. Further, when a predetermined part of a touch screen is touched, the touch screen function may enter a keyboard mode. [22] The input/output inteface module may include at least one of a keyboard, a mouse and a universal serial bus (USB) port. [23] The video distributor may group the display units into a plurality of groups, and distributes the musical score and the command to the display units differently according to groups. [24] Each of the display units constituting the user display part may be adjusted in height and angle by a motor-driving unit. [25] The system may futher include a group server to control groups of the display units and store the musical score if the display units of the user display part are grouped. [26] Another aspect of the present invention is to provide a system for providing an electronic musical score, the system including: a main server which stores a digital musical score and controls the system; a user interface unit which receives informaiton or a command from the exterior, and displays the information or the command through a display module under control of the main server; two or more user display groups which include two or more display units and displsys information containing a musical score through the respective display units under control of a video distributor; a group server which receives an approval signal from the main server and controls a corresponding user display group among the two or more user display groups; and the video distributor which controls screens to be displayed on the respective display units that belong to the corresponding user display group under the control of the group server. Advantageous Effects

[27] A musical score and/or information is efficiently and automatically provided to each musician or a member of a chorus hile playing or singing. Further, there is no need of turning a paper musical score, so that a musician or a member of a chorus can concentrate on playing or singing. Brief Description of the Drawings

[35] Hereinafter, emebodiments of the present invention will be described with reference to accompanying drawings.

[36] FIG. 1 is a block diagram of a system for providing an electronic musical score.

Referring to FIG. 1, a system for providing an electronic musical scrore includes a user interface unit 10, a main server 20, a video distributor 30, and a user display part 40.

[37] The user interface unit 10 allows a user to input information and various commands. The main server 20 stores diverse information such as a musical store or the like, controls the command input through the user interface unit 10, and stores the input information. The video distributor 30 controls display units of the user display part 40 individually or in group under control of the main server 20.

[38] FlG. 2 is a block diagram of a user interface unit according to an exemplary embodiment. As shown in FIG. 2, the user interface unit 10 includes a display module 102 and an input/output interface module 103.

[39] The display module 102 of the user interface unit 10 displays information from the main server 20 or informaiton from the input/output interface module 103 to be displayed on the user display part 40 under the control of a controller 201 provided in the main server 20. Here, the user display part 104 may include liquid crystal display (LCD) monitors having a touch screen function.

[40] The input/output interface module 103 of user interface unit 10 receives the command or information from a user, and the display module 102 displays the command of information input from a user under the control of the controller 201 of the main server 20. Here, the input/output interface module 103 may include at least one of universal serial bus (USB) ports for a keyboard or a mouse.

[41] For example, if a conductor inputs information and a command through the keyboard of the input/output interface module 103, the display module 102 of the user interface unit 10 displays the information and the command under the control of the controller 201 provided in the main server 20.

[42] FIG. 3 illustrates a screen of a display module provided in the user interface unit by way of example. Referring to FIG. 3, the display module 102 of the user interface unit 10 may divide the screen into left and right parts like a real paper musical score. Further, the screen may be divided into a plurality of parts to display a plurality of musical scores or to display a plurality of pages of the musical scrore for one song at the same time. Here, the display module 102 of the user interface unit 10 may have a resoultion higher than SXGA (i.e., more than 1280 ppi * 1024 ppi).

[43] Further, the display module 102 of the user interface unit 10 may have the touch screen function. The touch screen function is convenient for a user to easily input the command or information with a finger, a baton or the like.

[44] Meanwhile, a mode switching window 1021 may be displayed at a predetermined region of the touch screen, so that the touch screen can enter a keyboard mode. For example, if a user has to input the command or information without the keyboard or the mouse, the touch screen displays a virtual keyboard when he/she touches the mode switchig window 1021, so that a user can input the information through the virtual keyboard displayed on the touch screen. [45] FIG. 4 is a block diagram of a main server. Referring to FIG. 4, the main server 20 includes the controller 201 and a memory 202.

[46] The controller 201 of the main server 20 controls the user intreface unit 10 and the video distributor 30. Further, the controller 201 controls the display modue 102 of the user interface unit 10 to display information about the digitally stored musical score, and controls the video distributor 30 to make the respective display units constituting the user display part 40 display the musical score individually or in a group. Here, such control function may be provided as firmware in the controller 201 of the main server 20, or stored as software in the memory 202 of the main server 20 and then executed by the main server 20.

[47] The memory 202 of the main server 20 stores the musical score and voice data required in playing and/or singing. For example, if the present system for providing the electronic musical score is installed for the choir in church, the memory 202 of the main server 20 may store musical scores for all hymns, music scores for all gospels, chorus data of all hymns for referring to a professional chorus when the choir trains for the hymns, accompaniment data of all hymns needed when the choir songs the hymns after listening the hymns song by the professional chrorus, accompaniment data of all gospels.

[48] In the meantime, if there is a need of storing a new song or voice data, the main server 20 connects with an external storage unit through the USB or the like and a user inputs the command through the user interface unit 10, so that the controller 201 of the main server 20 can control the memory 202 to store the song or the voice data input through the USB. Alternatively, the external data may be input through a local area network (LAN) or a wireless network as well as the USB. In case of using the LAN or the wireless network, there is additionally needed a communication module to be connected with the LAN or the wireless network.

[49] FTG. 5 is a block diagram of a controller of the main server. As shown in FIG. 5, the controller 201 of the main server 20 includes a log-in controller 2011, a training controller 2012, a playing controller 2013, and a management controller 2014.

[50] The log-in controller 2011 checks access authority to the system for providing the electronic musical score, and approves access of an authenticated user. The training controller 2012 provides a function for training the successfully logged-in user. The playing controller 2013 provides a play list while a musician plays a music instrument using the system for providing the electronic musical score. The managment controller 2014 controls data about the musical score to be systematically managed. [51] Detailed descriptions of the log-in controller 2011 are as follows. In generarl, the log-in controller 2011 may consider a user and his/her level with respect to the authority approval. For example, the highest level user may access all functions and/or all data of the system; the next first level user may access the limited functions and/or data of the system; and the next second level user may access the more limited functions and/or data of the system.

[52] For exaple, the conductor and the musician (or the member of the chorus) may be different in the access authority from each other. In this case, the conductor is allowed to access all the functions of the system, but the musician (or the member of the chorus) may be allowed to access the limited functions. ,

[53] Meanwhile, even though users have the same level, they may access the function and/or data corresponding to individually assigned ranges, respectively. For example, the conductors have the access authority of the same level, but one of them may access only the information and/or function opened to himself/herself. In other words, even though the present system is single, users using the present system may be grouped plurally. Thus, identification information for identifying each group is input along with data when the data is input, so that one of the conductors having the access authority of the same level can access only data corresponding to his/her group on the basis of the identification information.

[54] Accordingly, while approving the access authority, the access is vertically limited according to levels of the access autority and horizantally limited according to groups of users, so that the single system for providing the elctronic musical score can be independently used by the plurality of levels and the plurlity of groups.

[55] Detailed descriptions of the training controller 2012 are as follows. The tranining controller 2012 provides a musical score automatic turning function, a musical score mannual turning function, a memo function, a recording function, a user display , individual control function, and a musical score searching function.

[56] First, the musical score automatic turning function calculates time to be taken in playing or singing with respect to one page of the musical score, and turns the page of the musicsl score displsyed on the screen. For example, the training controller 2012 calculates the time to be taken in playing or singing a corresponding page in consideration of a metronom value, a note depending on the metronom value, and the number of bars, which are written in the musical score. Then, the corresponding page is automatically turned on the basis of the calculated time. This is performed only when the musical score automatic turning function is selected by a user. [57] FIG. 6 illustrates that the musical score is displayed according to the musical score automatic turning function. In FIG. 6, the screen is divided into two parts by way of example. Referring to FIG. 6, let's assume that, at the beginning, the first page is placed in the left side of the screen, and the second page is placed in the right side. After play of the second page is ended, the second page is still placed in the right side as it is, but the first page, of which play is already comleted, is replaced by the third page. Furthermore, when the play of the second page is ended and play of the third page is started, the second page is replaced with the fourth page. As the pages are turned in such a manner, the musician or the conductor needs not to move his/her eyes until the play of the current page of the musical score is ended, thereby concentrating on the play.

[58] In this embodiment, the musical score automatic turning function converts information about the musical score per page into time, and turns the corresponding page of the musical score at the moment when the calculated time assigned to the corresponding page elapses. In more detail, the time assinged to the corresponding page (i.e., a page time) is calculated in consideration of the number of bars in the corresponding musical score, the metronom value that represents how many times a reference note is repeated per minutes, and a musical time pattern.

[59] In the training controller 2012, the page time is calculated by the following Equation 1 with reference to the following Table 1.

[60] [Equation 1] [61] βOzxt

—PageTime

[62] Table 1

[63] [64] In the Equation 1, x is the number of bars; v is a reference note value for a metronom value; y is a metronom value; z is a musical time; and t is a reference note value for a musical time, in which the reference note values for v and t are referred to the Table 1 (i.e., t/v represents a ratio of the reference note values).

[65] For example, in the case where the musical score in a certain page shows ten bars, metronom values of v=1.5 and y=84, and a musical time of 6/8 (i.e., z=6, t=0.5), six eighth notes are played per one bar, so that sixty eighth notes are played in total ten bars. If these values are substituted for variables of the Equation 1, the page time is about 14.2857 seconds.

[66] In the meantime, under the condition of the musical score automatic turning function, the play time may vary accordng to the conductor's personality. Accordingly, it is preferable to allow a user to set up the play time as desired. In this case, a user can adjust the page time (i.e., the play time) by inputting a reference metronom value of a corresponding musical score. For example, a user may input a multiple (e.g., 1.2 times, 1.3 times, 0.9 times, 0.8 times, etc.) of the reference metronom value. Then, the training controller 2012 calculates the page time on the basis of the input metronom value, and turns the musical score according to the page time. Further, the user interface may allow a user to input numerals based on a multiple of a reference time (i.e., reference metronom value), or input a visually recognized change of the reference time through a continuous scroll bar. =

[67] The musical score mannual turning function allows the page of the musical score to be turned when a user touches the touch screen. If a user selects the musical score mannual turning function, the controller of the main server stops the musical score automatic turning function, and controls the page of the musical score to be turned forward or backward according to mannual turning input signals. This musical score mannual turning function is useful when a user repeatedly trains for a certain page.

[68] The memo function allows a user to draw up a memorandum on the musical score displayed on the screen. In this case, it is preferable that the display module 102 provided in the user interface unit 10 has a character recognition function as well as the touchscreen function. If a user (e.g., a conductor) makes a memorandum on a part of the dislayed musical score, the memorandum is stored along with the musical score in the memory 202. Thus, a user can see the previous memorandum on the musical score as necessary when the musical score is dislayed. Further, a user may select only the memorandum to be deleted or not to be shown. Such a memorandum may be written through not only the character recognition function but also the virtual keyboard displayed on the user interface unit 10.

[69] Further, the memo function allows the memorandum written by a user (e.g., a conductor) to be displayed on the user display part 40 in real-time. In this case, the display module 102 provided in the user interface unit 10 stores data about the memorandum, which is input through the displayed screen and recognized as a character, in real-time, and transmits a corresponding data signal to the user display part 40 via the input/output interface module 103.

[70] The recording function allows sound input through a microphone to be stored in the memory 202 of the main server 20. The stored sound data can be output through an external audio device, and thus a musician or a singer can use his/her own play or song for training.

[71] The user display individual control function allows the screens of the respective display units constituting the user display part 40 to be controlled individually or in a group. For example, if a conductor wants to send a message to a certain part or an individual, he/she can input the message through the display module 102 of the user interface unit 10 and select a group or an individual through a display window. Then, the controller 201 of the main server 20 transmits a control signal to the video distributor 30 so that the display units of the designated grouop or the display unit of the individual can display the message written by the conductor. Under the control of the controller 201, the video distributor 30 controls the respective display units of the user display part 40 for the designated group or the individual to display the message written by the conductor. [72] For example, if a conductor wants to send a message with regard to a certain bar of a soprano part, he/she writes the message on the musical score displayed on the display module 102 of the user interface unit 10 and selects the soprano part, so that the message can be displayed on the display units of the soprano part.

[73] On the other hand, in the case that the same message is sent to all members of the chorus, a conductor can use the input/output inteface module 104 of the user interface unit 10, the character recognition function of the touch screen, or the keyboard mode for the tourch screen for sending the message to all of the members. At this time, the user display part 40 may display only the message from the conductor without displaying the musical score.

[74] The musical score searching function allows a user to search the musical scores digitally stored in the memory 202 of the main server 20. When a user inputs a retrieving condition through the keyboard or the mouse of the usser interface unit 10 or through a searching window activated in the keyboard mode for the touch screen provided in the display module 20 of the user interface unit 10, the music score matching with the searching condition is displayed. In the musical score searching function, the searching operation can be performed according to variouns conditions such as the whole or partial title of a song, a genre of a song, a musical time pattern, a play time of a song, etc.

[75] Detailed descriptions of the playing conroller 2013 are as follows. The playing controller 2013 provides a play list required in a practical play. In the practical play, a large repertoire of songs are played successively. It is inefficient that one song is ended and then the next song is searched. Accordingly, the list of songs to be played is previously stored and put in order, so that the musical scores can be displayed in order according to the play list. Here, the playing controller 2013 reads the musical scores corresponding to a plurality of songs from the memory 202 of the main server 20 and controls the read musical scores to be displayed in order of the play list.

[76] For example, if the present system is used in a church, the holly bible, a response reading versicle or the like may be displayed in addition to the musical score. In other words, if a church service is held in order of reading the holly bible, playing a hymn, response reading, playing a hymn, and so on, the playing controller 2013 may control passages of the bible, the response reading versicle, etc. as well as the musical score to be displayed in order of a list on the display module 102 of the user interface unit 10 and/or the respective display units of the user display part 40.

[77] Detailed descriptions of the menagement controller 2014 are as follows. The management controller 2014 peforms a musical score managment function. The musical score managment function converts a paper musical score into a digital musical score. In other words, the paper musical score is scanned into digital image information, and the digital image information is converted into the digital musical score by the management controller 2014.

[78] If the digital image information is input through the input/output interface module

103 of the user interface unit 10 or through the LAN or the whireless network, the controller of the main server 20 controls the digital image information to be converted into the digital musical score.

[79] The video distributor 30 uses a distributor for 2 -32 ports according to the number of monitors for members, and connects the ports in series and/or in parallel, thereby controlling the respective display units of the user display part 40.

[80] Meanwhile, all or a part of the display units of the user display part 40 may be adjusted in height and angle by motor-driving units. Further, the motor-driving units may be interlocked to each other, so that the height of every display unit can be adjusted by manipulating one motor-driving unit.

[81] Further, the display units of the user dislay part 40 may include not only the LCD but also a beam projector. For example, if the present system is employed for the choir in church, the beam projector may show present believers or an accompanist.

[82] On the other hand, a group server instead of the main server 20 may be provided for controlling the system in a group.

[83] FIG. 7 is a block diagram of another system for providing an electtronic musical score. Referring to FIG. 7, a system for providing an electronic musical score according to this embodiment includes a user interface unit 10, a main server 20, a group interface unit 50, a group server 60, a video distributor 30, and a user display part 40 having a plurality of display units.

[84] The embodiment shown in FIG. 7 has substantially the same function as that shown in FIG. 1. As compared with that of FIG. 1, the system according to this embodiment further includes the group interface unit 50 and the group server 60 to control the groups individually when the display units constituting the user display part 40 are grouped into several groups.

[85] For example, if soprano members of the chrous make mistakes frequently, a conductor instructs a lear of a soprano group to train the soprano members repeatedly. At this time, the conductor inputs a command for authorization to the group server for the soprano group thorugh the user interface unit 10. Then, the controller 201 of the main server 20 inputs an approval signal to the group server 60 so as to control the display units assigned to the group server.

[86] When the approval signal is input to the group server 60, a message about the approval is displayed on the group interface unit 50. Thereafter, the display units assigned to the group server 60 are preferentially controlled by the group server 60. At this time, the other groups may operate under control of the main server 10.

[87] As described above, various exemplary embodiments have been described with the drawings and the specifications. For reference, terms employed herein are not used for narrowing the meaning and limiting the scope of the invention. Accordingly, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
