Description

  The present invention relates to a display method, system and program for a plurality of display devices, and more specifically to a display method, system and program for a plurality of display devices which display data files including a plurality of pages on the screens of a plurality of terminals.

2. Description of the Related Art Various systems have been used in which contents such as documents and musical scores that have been conventionally provided by printing on paper media are displayed on various rewritable display devices and provided to users. In other words, books and music scores were conventionally provided in print media, but they become thicker if the number of pages is large, and many books cannot be carried around. Instead, the content is stored and displayed on a smartphone or tablet terminal instead. This makes it easy to carry and allows many books and musical scores to be used at any location. Here, a device that displays a score using a display device such as a smartphone or a tablet terminal has been proposed (for example, see Patent Document 1). Japanese Patent Application Laid-Open No. 2004-228561 displays a score on a tablet or the like and scrolls it so that a performer or a singer can easily view it. However, only one page of score can be displayed on one display device. Since most books and musical scores are spread, it is more convenient to display each page on two display screens from the viewpoint of use. In consideration of this point, an apparatus (electronic score) for displaying a score in a spread is proposed (for example, see Patent Document 2). In the electronic musical score of Patent Document 2, two display screens are spread and displayed like a normal musical score, and the image data of the next page is acquired and displayed by turning the page.

Similarly, when using three display devices, the first page is displayed at the left end, the second page is displayed at the center, and the score of the third page is displayed at the right end display device. When the page is turned once, the fourth page is displayed at the left end, the fifth page is displayed at the center, and the score of the sixth page is displayed at the right end.

(Configuration of this embodiment)
Although the outline of the display method of the present embodiment is as described above, specific operation and processing of the system will be described below. FIG. 1 is an overall system configuration diagram of an embodiment of the present invention. This system includes a score distribution server 101 and a communication server 102 as servers for distributing score data and controlling the entire system, and is connected via a network 103. The terminals 111 to 112 as display devices are basically connected to the network 103 wirelessly, and can be, for example, tablet terminals. In this embodiment, the connection to the network 103 is a line of a mobile phone, Wi -Performed by a wireless network such as fi, BLUETOOTH (registered trademark). Here, the terminals 111 and 112 can be smartphones, mobile personal computers, etc. in addition to tablet terminals. Basically, musical score data and the like are received from a server to display an image, and a touch panel, a mouse or a keyboard can If an input operation can be performed, any device such as a mobile or desktop personal computer or a dedicated terminal can be used.

  In the present embodiment, the smartphone 113 is used for operations when displaying musical scores and the like on the terminals 111 and 112 such as page designation and page turning instructions, and is a server via the network in the same manner as the terminals 111 and 112. Any terminal device can be used as long as it can communicate with the mobile phone, and a fixed device such as a personal computer can also be used. In addition, the server of this embodiment includes two servers, the score distribution server 101 and the communication server 102. When an instruction to display an image such as a score or page feed is transmitted from the smartphone 113 to the communication server 102, the communication server 102 102 designates a page of image data, a display device, and the like and instructs the score distribution server 101. The score distribution server 101 transmits the image data of the designated page to the designated display device 111 or 112 for display. However, the present invention is not limited to this, and one server can be configured to receive instructions and transmit image data, or more servers can share functions.

  FIG. 2 is a functional block diagram of a server according to an embodiment of the present invention. The score distribution server 101 receives and stores score data from a server (not shown) or the like, receives and stores score data, a management module 201, a score that generates image data of each page from the received score data, an image conversion module 202, and An image data management / transmission module 203 is provided that stores and manages the generated image data and transmits the image data to a designated terminal upon receiving an instruction from the communication server 102. Further, the communication server 102 receives position information in the arrangement of terminals from the terminals 111 and 112, determines and stores the arrangement of the terminals, receives the designation from the terminal designated for management, the arrangement management module 204, and the smartphone 113. Terminal designation reception, instruction reception for managing on which display device the image of each page of the score data is displayed based on the terminal position information managed by the arrangement management module 204, the terminal management module 205 and the received instruction An image transmission instruction module 206 that transmits the image data to be displayed determined based on the information to the terminal 111 or 112 to be displayed.

  Below, the process of this embodiment is demonstrated with reference to FIGS. In this embodiment, first, the server is informed in what order the display devices are arranged (display device position setting), and then an operation related to display is performed from a smartphone or the like that is an instruction device. , Display the image of each page of the score and perform page turning processing.

(Display device position setting process)
FIG. 3 is a diagram for explaining setting of the arrangement of the display device according to the embodiment of the present invention. FIGS. 4A and 4B illustrate the arrangement of the display devices managed by the server according to the embodiment of the present invention. It is a figure which shows information. FIG. 5 is a diagram for explaining the display operation of each page image of the server and the display device according to the embodiment of the present invention. FIG. 6 shows the processing of the entire system according to the embodiment of the present invention. It is a flowchart.

  In this embodiment, as shown in FIG. 3, the position is set by a simple method in each terminal and notified to the server, so that the server determines the arrangement of the terminals, and then transmits which page image to which terminal. To decide. In other words, each terminal is set by operating the touch panel or the like (by sliding the finger), but the right terminal slides the finger from the center to the right edge of the terminal display screen, and the center terminal points from the left edge to the right edge of the screen. And the terminal at the right end sets the position of each terminal by sliding a finger from the left end of the screen to the center. The set information (position designation information) is sent from each terminal to the server, so that the server determines the position of each terminal, and the determined arrangement is stored in the communication server 102 as shown in FIGS. 4A and 4B, for example. Is done. By setting in this way, it is possible to register the arrangement by simply operating each terminal in a state where the terminals are arranged without having to set the position of the terminal in the server in association with the terminal name. Therefore, it does not take extra time and can be operated flexibly.

  Specifically, referring to the flowchart of FIG. 6, first, in step S <b> 601, the number of terminals to be used is input to any terminal and transmitted to the communication server 102. Next, the case of using three terminals will be described with reference to FIG. 3 as an example. First, the pointer is moved from the center to the right on the screen of the first (left end) terminal. That is, when a finger is pressed near the center of the leftmost terminal screen, a pointer is displayed on the screen (step S301), and the finger is slid to the right (step S302). The terminal at the left end transmits information to the communication server 102 that the finger has been slid from the center to the right end (position designation information).

  When the terminal designation reception / location management module 204 of the communication server 102 receives the position designation information of the leftmost terminal, it determines that the writing direction is right and the terminal is the leftmost terminal because it is a right slide from the center to the right edge. Remember. Specifically, for example, as shown in FIG. 4A (when the terminal name of this terminal is terminal 3), the left end is recorded in the item 405 of the arrangement information 401 (step S602).

  Next, when the left end of the central terminal screen is pressed, a pointer is displayed on the screen (step S303), and the pointer is slid to the right end (step S304). The central terminal transmits to the communication server 102 information (position designation information) that the slide has been made to the right end. When the terminal designation reception / location management module 204 of the communication server 102 receives the position designation information of the central terminal, the terminal that has transmitted is determined to be the central terminal based on the position designation information and stored. Specifically, for example, as shown in FIG. 4A (assuming the terminal name of the central terminal is terminal 1), the center is recorded in the item 403 (step S602).

  Similarly, when the left end of the screen of the right end terminal is pressed, a pointer is displayed on the screen (step S305), and the pointer is slid to the center (step S306). The rightmost terminal transmits information (position designation information) that the center is slid to the communication server 102. When the terminal designation reception and arrangement management module 204 of the communication server 102 receives the position designation information from the rightmost terminal, the terminal that has transmitted is determined to be the rightmost terminal and stored. Specifically, for example, as shown in FIG. 4A (when the terminal name of this terminal is terminal 2), the right end is recorded in the item 404 (step S602). Intuitively, these operations are performed by sliding the screen in order from the terminal at the end according to the writing direction, that is, by touching the terminal from the center of the left end with your finger to trace the continuous terminal. Easy to understand.

  With the above processing, the positional relationship and the writing direction of the three terminals are determined, and using these pieces of information, a score and the like can be displayed on the three terminals. In this embodiment, the number of terminals to be used at the beginning of the setting is input from one of the terminals and transmitted to the server. However, even if the number of terminals is not input, the above operation confirms the position registration for three terminals. For example, the number can be automatically determined to be three. In this case, for example, a button for starting position setting (not shown) is displayed on the terminal, and when this button is pressed, the setting is started. When the server does not receive a notification of setting for a certain period of time from the last input, it is determined that the setting is finished. Thus, the number of terminals set so far can be set as the number of terminals.

  Moreover, although the said operation was performed from the terminal of the left end, since the position of a terminal is determined by the position to slide as mentioned above, it is not necessarily restricted to this, Operation may be started from a center terminal, Operation can be performed in any order from the terminal. In this case, when setting the position of four or more terminals, since two or more terminals are arranged in the center excluding the left and right ends, for example, by performing the position setting operation in order from the left terminal The server can determine the central terminal number.

  Furthermore, although the writing direction is right in the present embodiment, the present invention can also be applied to the case where the writing direction is left, in which case the terminal position determination is reversed. That is, the slide at the time of setting on the screen of the terminal at the right end or the left end can be determined in the same manner as described above by setting the center to the left end or the right end to the center. Further, even when the terminals are arranged one above the other, the setting at the terminal and the determination at the server are possible by using the principle of the present invention. Further, since the operation is assumed to be a tablet in the present embodiment, the movement of the pointer is a swipe operation with a finger, but it can also be set by moving the pointer displayed on the screen with a mouse or the like.

  Next, an array setting operation and an array determination method when there are two display devices will be described with reference to FIG. Basically, it is the same as the setting and determination method described above, and when two units are used, there is no central display device when three units are used.

  Specifically, referring to the flowchart of FIG. 6, first, in step S <b> 601, the number of terminals to be used is input to any terminal and transmitted to the communication server 102. First, the pointer is moved from the center to the right on the screen of the first (left side) terminal. That is, when a finger is pressed near the center of the left terminal screen, a pointer is displayed on the screen (step S901), and the finger is slid to the right (step S902). The left terminal transmits to the communication server 102 information (position designation information) that the finger has been slid from the center to the right end.

  When the terminal designation reception / location management module 204 of the communication server 102 receives the position designation information of the left terminal, it determines that the writing direction is right and the terminal is the left terminal because it is a right slide from the center to the right end. Remember. Specifically, for example, as shown in FIG. 4B (if the terminal name of this terminal is terminal 4), the left end is recorded in the item 407 of the array information 406 (step S602).

  Next, when the left end of the screen of the right terminal is pressed, a pointer is displayed on the screen (step S903), and the pointer is slid to the center (step S904). The terminal on the right side transmits information (position designation information) that the user has slid to the center to the communication server 102. When receiving the location designation information from the right terminal, the terminal designation reception / location management module 204 of the communication server 102 determines that the terminal that has transmitted is the right terminal and stores it. Specifically, for example, as shown in FIG. 4B (if the terminal name of this terminal is terminal 5), the right end is recorded in item 408 (step S602).

  With the above processing, the positional relationship and the writing direction of the two terminals are determined, and using these pieces of information, a score or the like can be displayed on the two terminals.

(Image display processing)
Next, in step S603, an instruction to distribute a score is transmitted from the smartphone 113, and when the instruction is received by the communication server 102 and received by the terminal management module 205, the image of the specified page is distributed to the image distribution server 101. Therefore, the terminal on which the image of the designated page is to be displayed is determined. That is, for example, when displaying on one terminal 521 that displays an image, it is only necessary to instruct the terminal 521 to transmit the image data of the designated page as it is. In this case, it is necessary to determine how many pages of image data are transmitted to which terminal. For example, if any one of the terminals 531 and 532 is specified and an instruction to display the fourth page image is given, the third page image is transmitted to the terminal 531 and the fourth page image is transmitted to the terminal 532. Next, the score distribution server 101 is instructed (step S604). Upon receiving such an instruction, the instruction reception / terminal management module 205 stores and manages how many pages of images are currently displayed on which terminal.

  In addition, although the example which performs a display instruction | indication using the smart phone 113 was demonstrated here, as shown in FIG. 8, including the page turning and other operation which are demonstrated below, each terminal 521, 531, 532, 541 for a display is shown. , 542 and 543 can also be used. In that case, the smartphone 113 becomes unnecessary. In this case, it is also possible to send only the page desired to be displayed without designating the terminal to be displayed. Such designation can be interpreted as the terminal to which the instruction is transmitted is designated, and the above-described processing can be performed. .

  Similarly, when any one of the terminals 541, 542, and 543 is designated and the display of the image of the fourth page is instructed, the image of the fourth page is displayed on the terminal 541, and the image of the fifth page is displayed on the terminal 542. Then, the score distribution server 101 is instructed to transmit the image of the sixth page to the terminal 543 (step S604). Here, in the present embodiment, the instruction from the smartphone 113 includes a page for which a score is desired to be displayed and designation of at least one of the arranged terminal groups, but is not limited to this. Terminal information can also be included.

  In the score distribution server 101, the score data reception and management module 201 receives and manages score data from the score database 501, and the score-to-image conversion module stores the score data from the score data in PDF format for each page. Separated into images, stored and managed. When an instruction for transmitting image data is given from the communication server 102 by designating a terminal and a page to the score distribution server 101, the image data management and transmission module 203 reads the image of the designated page and transmits it to the designated terminal. . In the example of the above instruction, the third page image is transmitted to the terminal 531, the fourth page image is transmitted to the terminal 532, the fourth page image is transmitted to the terminal 541, and the fifth page is transmitted to the terminal 542. The image of the sixth page is transmitted to the terminal 543.

(Page turning process)
FIG. 7 is a diagram for explaining the page turning operation of the server and the display device according to the embodiment of the present invention. With the method as described above, when an image of several pages has already been displayed on each terminal, when a swipe operation is performed on the terminal 702 as shown in FIG. 7, the image of the next page is displayed. Since two terminals are used in this example, pages are sent two pages at a time when the page is turned. That is, if the page is turned (swipe etc.) while the images of the first and second pages are displayed, the images of the third and fourth pages are displayed, and if the pages are turned further, the fifth and sixth pages are displayed. Is displayed.

  A specific process will be described. When the images of the first and second pages are displayed, swiping the screen of the terminal 702 with a finger transmits a page turning (page feed) instruction to the communication server 102 ( Step S606). Since the instruction reception and terminal management module 205 recognizes that the images of the first page and the second page are currently displayed, the terminal management module 205 determines to display the images of the third page and the fourth page according to the page turning instruction. Terminals to be displayed are also determined, and a transmission instruction is given to the score distribution server 101 (step S604). Receiving the instruction, the score distribution server 101 transmits the image data of the instructed page to the instructed terminal, and each terminal displays the received image data. Here, since the instruction reception and terminal management module 205 manages how many pages the image currently displayed on each terminal is, each terminal only gives an instruction to display an appropriate page by a page turning instruction. Although it can be transmitted to the distribution server 101, for example, the page displayed on each terminal is also managed by each terminal, and the page is also transmitted at the time of page turning instruction. Even if there is no page information displayed, the page turning process can be appropriately performed.

  The page turning when displaying on two terminals has been described above. Similarly, according to the present invention, the page turning process can be performed even when displaying an arbitrary number of terminals. For example, when using three display devices, if you perform a swipe operation on the screen of any of the three terminals, pages are sent three pages at a time. For example, the first page, second page, and third page images are displayed. If the page is turned (swipe or the like) in the state of being turned on, the images of the fourth page, the fifth page, and the sixth page are displayed.

  Although not shown, when returning the page, for example, when the images of the 5th page and the 6th page are displayed, swiping right on the terminal of FIG. 9, the images of the 3rd page and the 4th page Will be displayed. Further, in the above description, the page turning is performed on the terminal 702, that is, the right terminal. However, the present invention is not limited to this, and the page turning operation can be performed on the left terminal.

  In the present embodiment, the multi-image display method using two and three display devices has been described. However, the various methods of the present embodiment described above can be changed according to the number of units to display an arbitrary number of units. The present invention can also be applied to a system using an apparatus. In the present embodiment, the writing direction is right, but the present invention is also applicable to the case where the writing direction is left. In this case, the page displayed on the terminal is in the opposite direction. If one of the terminals 531 and 532 is designated and the display of the fourth page image is instructed, the third page image is displayed on the terminal 532 and the fourth page is displayed on the terminal 531. An image is displayed. Similarly, if any of the terminals 541, 542, and 543 is designated and the display of the image of the fourth page is instructed, the image of the fourth page is displayed on the terminal 543, and the image of the fifth page is displayed on the terminal 542. The image of the sixth page is displayed on the terminal 541. The direction of page turning is also reversed, and referring to FIG. 7, swiping left to turn turns the page, but if the writing direction is left, swiping right to the reverse turns the page turning operation. . Furthermore, even when terminals are arranged one above the other, an image of an appropriate page can be displayed on the terminal by using the principle of the present invention.

(Second embodiment)
This embodiment basically has the same configuration as that of the first embodiment described above, and the setting of the arrangement of each terminal is performed in the same manner. It is also the same that images of pages continuous in the writing direction are displayed on a plurality of terminals based on the array set in such a manner. The main difference between the present embodiment and the first embodiment is the designation method at the start of display and page turning. Hereinafter, the present embodiment will be described focusing on this difference, but basically the processing of the first embodiment can be used except for the difference as described above.

  In the image display process of the first embodiment described above, when an instruction to distribute a score is transmitted from the smartphone 113 or each terminal together with the specified page, the terminal on which the image of the specified page is to be displayed is displayed. It is determined. However, in the present embodiment, such processing is not performed, the designated page is transmitted to the designated terminal, and the image of the page that matches the designated terminal is transmitted to the other terminals. That is, for example, when displaying on one terminal 521 that displays an image, it is only necessary to instruct the terminal 521 to transmit the image data of the designated page as it is. In this case, the image data of the designated page is transmitted to the designated terminal, and it is determined which page is to be displayed on the other terminals according to this.

  For example, when the terminal 531 is designated and the display of the fourth page image is instructed, the score distribution server transmits the fourth page image to the terminal 531 and the fifth page image to the terminal 532. 101 is instructed (step S604). Upon receiving such an instruction, the instruction reception / terminal management module 205 stores and manages how many pages of images are currently displayed on which terminal. Similarly, if the terminal 542 is specified when three terminals are used and the display of the fourth page image is instructed, the third page image is displayed on the terminal 541, the fourth page image is displayed on the terminal 542, the terminal In 543, the score distribution server 101 is instructed to transmit the image of the fifth page (step S604). After the image is displayed on each terminal as described above, the page can be turned by swiping on the screen as in the first embodiment as shown in FIG. In the present embodiment, as in the first embodiment described above, when pages are turned on the screen of the terminal 702, that is, the terminal on the right side, pages are sent page by page. However, when page turning is performed at the terminal 701, that is, the terminal on the left side, unlike the first embodiment, the page can be turned page by page. FIG. 7 shows such an example. As shown in FIG. 7, when the screen of the terminal 702 is swiped to the left for page turning, page turning is performed two pages at a time, but the screen of the terminal 701 is changed to page turning. Therefore, if you swipe left, the page will be paged page by page. By changing the page-turning terminal in this way, the number of pages to be turned one page at a time or two pages at a time can be changed, and a flexible operation can be performed.

  Such a page turning change can also be applied to three or more terminals. For example, when using three terminals, if page turning is performed at the leftmost terminal, pages are sent three pages at a time, and page turning is performed at the central terminal. If page is turned, page turning is performed two pages or one page at a time, and page turning is performed page by page by turning the page at the right end terminal.

  In addition, although the operation of returning the page as in the first embodiment can be performed by swiping, the number of pages returned by the operating terminal can be changed also in this case.
