Description

  The present invention relates to a display device including a plurality of displays and a configuration setting method thereof.

  In recent years, large screens such as 45 inches or 60 inches have been used for information displays or commercial displays. Furthermore, for lecture halls or movie theaters, there are display devices configured such that a plurality of, for example, four or nine displays are arranged adjacent to each other to make a larger screen and display one video.

  A plurality of displays constituting the large screen are serially connected through, for example, a COM (Communication) port, and video signals are supplied to individual displays by a DVI (Digital Visual Interface) signal from the server. Alternatively, they are connected by a LAN (Local Area Network), and each video is supplied in a streaming form from a server. The server needs to recognize the configuration of the display in order to provide an individual video for each display. When this configuration is recognized manually, the number of steps for recognizing the configuration increases as the number of displays increases.

In this multi-panel system, each panel receives the array position data, and stores the supplied array position data as the array position of its own panel. Array position data is generated and supplied to the next stage. The final panel stores the supplied arrangement position data as the arrangement position of its own panel, and when the supplied arrangement position data is transmitted to the previous stage, the panel before the final panel receives the arrangement position data from the final panel. Send to system controller. The system control apparatus recognizes the entire matrix arrangement based on the response of the array position data from the final panel. The arrangement of the panel can be automatically recognized, and the trouble of supplying the arrangement data can be eliminated (for example, see Patent Document 1).

  As a second conventional technique, there is an image display device that can be combined with a plurality of image display devices, that is, displays to form a multi-screen display device. This image display device has a configuration in which the number of connections in the vertical direction and the number of connections in the horizontal direction are 3 or less, and the position of the image display device in the configuration of the multi-screen display device based on the connection state with other adjacent image display devices Can be automatically determined (see, for example, Patent Document 2).

The client ID is assigned to each client 20 in advance and is set in a storage device (not shown) of each client.

  After the client is arranged, the display system 1 sets the configuration of the actually arranged client by manual setting that is manually set or automatic setting that is automatically set.

  FIG. 6 shows an example of the configuration setting screen 40 in the server 10 shown in FIG. The configuration setting screen 40 shown in FIG. 6 is a screen that is output to an output device (not shown) of the server 10, and is a screen for manually setting the configuration of each client 20 that is actually arranged in the server 10. is there. An area 41 for displaying the client 20 to be set is on the right side of the configuration setting screen 40, and an area on the left side is a map area for setting the client 20 to a position corresponding to the position where the client 20 is actually arranged. The case of the configuration of two vertical rows and two horizontal rows shown in FIG. 2 will be described as an example.

  FIG. 6A is a configuration setting screen in which the arrangement position has not yet been set, and the client 20 to be set is displayed in the area 41. The client 20 to be set is the client 20 from which the server 10 has received the adjacent information, and is displayed from the upper side of the area 41 in the order in which the adjacent information is received, for example. The client ID of the first client 20 is “C”, the client ID of the second client 20 is “A”, the client ID of the third client 20 is “B”, and the fourth client 20 The client ID is “D”.

  The user selects the client 20 to be set first using an input device (not shown) of the server 10. At this time, the server 10 instructs the selected client 20 to display that it is selected. For example, a display in which the screen color is changed to a color different from that of the other client 20, a display of the MAC (Media Access Control) address of the client 20, or a display for flushing the screen is instructed.

  FIG. 6B shows a state in which the first client 20 is set at the position of the map area corresponding to the actual position. The user confirms the actual position of the first client 20 selected in FIG. 6A, that is, the client 20 with the client ID “C”, and puts the client 20 at the position of the map area corresponding to the confirmed position. Set.

  FIG. 7 shows the correspondence with the actual position of the client 20 displayed on the configuration setting screen 40 shown in FIG. FIG. 7A shows a state where the client C20C is selected. When the first client 20 in the area 41 shown in FIG. 6A is selected, the server 10 displays that the client 20 with the client ID “C” is selected, for example, a display that flushes the screen. Instruct. The client C20C flushes the screen according to an instruction from the server 10.

  FIG. 7B shows a state where the second client 20 in the area 41, for example, the client A 20A is selected. When the second client 20 in the area 41 shown in FIG. 6B is selected, the server 10 displays that the client 20 with the client ID “A” is selected, for example, a display that flushes the screen. Instruct. The client A 20A flushes the screen according to an instruction from the server 10.

  FIG. 8 shows an example of manual setting of the second client 20 on the configuration setting screen 40 shown in FIG. The user confirms the position of the flushed client 20 shown in FIG. 7B, and sets the second client 20, for example, the client A 20A, at the position of the map area corresponding to the position. Similarly, settings are made for the third and fourth clients 20.

  FIG. 9 shows an arrangement position of the client 20 manually set on the configuration setting screen 40 shown in FIG. The client A 20A as the second client 20 is set in the upper left, the client B 20B as the third client 20 is set in the upper right, the client C 20C as the first client 20 is set in the lower left, and the fourth in the lower right. Client D20D, which is the client 20 of, is set. The map manually set in the map area is stored in the storage device 11.

  The server 10 generates configuration information for each client 20 based on the map stored in the storage device 11. The configuration information is information representing the overall configuration of the client, for example, the number in the vertical direction and the number in the horizontal direction, and the position of each client 20 in the overall configuration. For example, in the case of the configuration shown in FIG. 9, the information “configuration is 2 * 2” indicating that the configuration is two vertical rows and two horizontal rows and the position is the first in the second row for the client C20C. Information “Position is 2-1” is generated. For the other clients 20, information “configuration is 2 * 2” and information indicating each position are generated. The generated configuration information is transmitted to each client 20 by the server communication unit 13 before transmitting the content. Each client 20 can recognize the location of the client 20 in the overall configuration from the received configuration information.

  FIG. 10 is a flowchart of the position setting process processed by the server 10 shown in FIG. The position setting process performs a process of setting the configuration of the client 20 (hereinafter also referred to as “monitor”), that is, the arrangement position. When the monitor configuration is set, the process proceeds to step F1.

  In step F1, it is determined whether or not to use the previous setting. In other words, for example, when an input device (not shown) instructs to use the previous monitor configuration setting stored in the storage unit 11, it is determined to use the previous setting. If the previous setting is used, the process proceeds to step F5. If the previous setting is not used, the process proceeds to step F2. In step F2, it is determined whether or not automatic setting is performed. That is, for example, if there is an instruction to automatically set the monitor configuration by an input device (not shown), it is determined that automatic setting is to be performed. If automatic setting is to be performed, the process proceeds to step F7. If automatic setting is not to be performed, the process proceeds to step F3.

  In step F3, the configuration is manually set. In the manual setting, for example, the monitor configuration is set on the configuration setting screen 40 shown in FIG. In step F4, the current setting is saved and the process ends. That is, the setting of the monitor configuration newly set in step F3 is stored in the storage unit 11, and the process ends. In step F5, it is determined whether there is a set value. That is, when the monitor configuration setting is stored in the storage unit 11, it is determined that there is a set value. If there is a set value, the process proceeds to step F6, and if there is no set value, the process proceeds to step F2. In step F6, the previously stored set value is used and the process ends. That is, the setting of the monitor configuration is set as it is in the setting value stored in the storage unit 11, and the process ends.

  In step F7, an automatic setting process described later for automatically setting the monitor configuration is called. In step F8, an effective block selection process (to be described later) for selecting a group of monitors for displaying content is called. The effective block is a block for displaying content among blocks constituted by adjacent monitors. In step F9, the current setting is saved and the process ends. That is, the setting of the monitor configuration newly set in step F7 and step F8 is stored in the storage unit 11, and the process ends.

  FIG. 11 shows an example of a reception array and a piece array used by the server 10 shown in FIG. In the figure, “piece” is also referred to as “Piece”. FIG. 11A shows a monitor state and a reception array corresponding to the monitor state. The monitor state indicates the actual configuration of the monitor. The reception arrangement is an arrangement in which adjacent information received from each monitor by the server 10 is arranged, for example, in the order of responses from the monitors, and is stored in the storage unit 11 of the server 10. The reception arrangement includes “up”, “left”, and “bottom” items indicating the client IDs of the monitors adjacent to the upper, left, lower, and right sides of each monitor. ”And“ Right ”items. Hereinafter, the client IDs shown in the “upper”, “left”, “lower”, and “right” item columns are referred to as adjacent monitor IDs.

  The monitor shown in FIG. 11A is composed of nine monitors in three rows and three rows. Three monitors with client IDs “B”, “D”, and “F” from the left are arranged in the upper row, and client IDs “C”, “E”, and “G” from the left are arranged in the middle row. ”And three monitors with client IDs“ A ”,“ H ”, and“ I ”from the left are arranged in the lower row.

  For example, for the monitor having its own ID “C”, the “upper” adjacent monitor ID is “B” and the “left” adjacent monitor ID is “NULL”. The “lower” adjacent monitor ID is “A”, and the “right” adjacent monitor ID is “E”. “NULL” indicates that there is no adjacent monitor. Similarly, when the self ID is “E”, “D”, “C”, “H”, and “G” are set, and when the self ID is “I”, “G”, “H”, “NULL” are set. ”And“ NULL ”, the self ID is“ D ”,“ NULL ”,“ B ”,“ E ”, and“ F ”, and the self ID is“ G ”,“ F ”, “E”, “I”, and “NULL”, and the self ID is “A”, “C”, “NULL”, “NULL”, and “H”, and the self ID is “F” Are “NULL”, “D”, “G”, and “NULL”, and for self ID “B”, are “NULL”, “NULL”, “C”, and “D”, and When the self ID is “H”, they are “E”, “A”, “NULL”, and “I”.

  FIG. 11B shows a piece array. The piece array is a two-dimensional array of received adjacent information items and “check” items indicating the arrangement confirmation status in the order of piece numbers indicating the order in which responses are received. The piece array has six items for each piece number: “own ID”, “upper ID”, “left ID”, “lower ID”, “right ID”, and “check”. Of these six items, items other than “check” correspond to the five items in the receiving array shown in FIG. The item “check” indicates the state of confirmation of arrangement, and values “0” to “2” are entered. “0” indicates that the arrangement has been confirmed, “1” indicates an initial value, that is, no confirmation has been performed, and “2” indicates that the arrangement has been confirmed. Is in a state where it is adjacent to a monitor that has not been confirmed yet.

  Each element of the piece array is represented by piece [m] [n]. [M] is a piece number. [N] is a number corresponding to six items of “own ID”, “upper ID”, “left ID”, “lower ID”, “right ID”, and “check”. ”Is a number assigned an integer from“ That is, "Own ID" is [0], "Upper ID" is [1], "Left ID" is [2], "Lower ID" is [3], "Right ID" is [4], and "Check" Is [5]. In the piece [0] [0] to piece [8] [4], the contents of the reception array shown in FIG. 38A are entered as they are, and “NULL” is entered as it is when there is no connection.

  FIG. 12 shows an example of the confirmed ID storage array used by the server 10 shown in FIG. The confirmed ID storage array sumi [] is an array for registering the client ID of the monitor whose arrangement has been confirmed, and is stored in the storage unit 11. In the figure, “sumi” is also referred to as “Sumi”. The monitor registered in the confirmed ID storage array is a monitor in which the check column of the piece array is “0”, and the client ID of the monitor, that is, “own ID” is registered in the confirmed ID storage array. The confirmed ID storage array shown in FIG. 12 is initialized and all are blank, that is, “NULL”.

  FIG. 13 shows an example of the end ID storage array used by the server 10 shown in FIG. The end ID storage array haji [] is an array for registering client IDs of monitors without a monitor adjacent to the left side and the upper side, and is stored in the storage unit 11. In the figure, “haji” is also referred to as “Haj”. The end ID storage array shown in FIG. 13A is initialized and all blanks, that is, the state of “NULL” is shown. The end ID storage array shown in FIG. 13B shows a state after the end ID search process described later is performed, and the monitor with the client ID “B” is registered. “Haji_count” used in the edge ID search process shown in FIG. 18 indicates the number of monitors without a monitor adjacent to the left side and the upper side, that is, the number of monitors registered in the edge ID storage array, and haji [0] to haji In [haji_count-1], the client ID of the monitor without the adjacent monitor on the left side and the upper side is registered.

  FIG. 14 is a flowchart of the automatic setting process called from the position setting process shown in FIG. The automatic setting process automatically sets the monitor configuration. When called in step F7 shown in FIG. 10, the process proceeds to step G1.

  In step G1, a configuration acquisition / storage process (to be described later) for storing adjacent information received from each monitor in a piece array is called. In step G2, a later-described confirmed ID storage array securing process for initializing the confirmed ID storage array is called. In step G3, an end ID storage array securing process (to be described later) for initializing the end ID storage array is called. In step G4, an end ID search process, which will be described later, for searching for a monitor without a monitor adjacent to the left and upper sides is called.

  In step G5, “block = 0”, “chk_total = 0”, and “BB = 0” are set. That is, the counter block for counting the number of blocks constituted by adjacent monitors, the number of confirmed monitors chk_total, and the end ID confirmation counter BB are cleared to “0”. In the figure, “block” is also referred to as “Block”, and “chk_total” is also referred to as “Chk_total”. In step G6, it is determined whether or not piece [] [5] ≠ 0 in the piece array having the ID of haji [BB]. That is, it is determined whether the value of the check item piece [] [5] in the piece array of the client ID of the client ID of the BB-th monitor in the end ID storage array haji [] is “0”, that is, whether or not it has been confirmed. If piece [] [5] ≠ 0, that is, if it has not been confirmed, the process proceeds to step G7, and if piece [] [5] ≠ 0, that is, if piece [] [5] = 0, the monitor has already been executed. Has already been set, the process proceeds to step G11.

  In step G7, a map storage process (to be described later) for determining a block constituted by adjacent monitors and creating a map of the monitor constituting each block is called. In step G8, “chk_total = chk_total + count + 1” is set. That is, the count value counted in the map storing process in step G7 and “1” are added to the number of confirmed monitors chk_total. In step G9, it is determined whether chk_total <total. If the confirmed number chk_total of the monitors is smaller than the total number of monitors, the process proceeds to step G10. If the confirmed number of monitors chk_total is not smaller than the total number of monitors, the process ends. In step G10, “block = block + 1” is set. That is, “1” is added to the block number block. In step G11, “BB = BB + 1” is set, and the process returns to step G6. That is, “1” is added to the end ID confirmation counter BB, and the process returns to step G6.

  FIG. 15 is a flowchart of the configuration acquisition / storage process called from the automatic setting process shown in FIG. In the configuration acquisition / storage process, a piece array is created to determine the total number of monitors. In the figure, “total” is also referred to as “Total”. When called at step G1 shown in FIG. 14, the process proceeds to step H1.

  In step H1, “total = 0” is set and piece [] is secured / cleared. That is, the total number of monitors is cleared to “0”, a storage area for storing the piece array is secured in the storage unit 11, and the storage area is cleared to NULL. In Step H2, an ID request is transmitted to the client 20, that is, the monitor through the control port. That is, a transmission request for neighboring information including the client ID of each monitor and the client ID of the neighboring client detected by each monitor is transmitted to each monitor via the control port. The control port is a channel for transmitting and receiving control information such as adjacent information and a transmission request thereof between the server 10 and the monitor, and a specific IP address and a Port number are assigned in the network channel. Channel.

  In step H3, it is determined whether or not there is a response from the monitor, that is, a response of adjacent information. If there is a response from the monitor, the process proceeds to step H4, and if there is no response from the monitor, the process proceeds to step H6. In Step H4, “piece [total] [0] = reception ID” is set, “reception neighbor information is stored in piece [total] [4] from“ piece [total] [0] ”, and“ piece [total] [5] ] = 1 ”. That is, the client ID of the monitor that transmitted the adjacent information included in the adjacent information is registered in the “own ID” of the total piece array, and the “upper ID”, “left ID”, and “lower” of the total piece array are registered. "ID" and "Right ID" include the client ID of the monitor adjacent to the upper side, the client ID of the monitor adjacent to the left side, the client ID of the monitor adjacent to the lower side, and the monitor adjacent to the right side. The client ID is registered. When there is no adjacent monitor, “NULL” indicating that there is no adjacent monitor is registered. An initial value “1” is registered in the “check” item of the total piece array.

  In step H5, “total = total + 1” is set, and the number of monitors responding to total is increased by “1”. In step H6, it is determined whether it is within the timeout. That is, it is determined whether or not a monitoring time for monitoring a response to the ID request transmitted in step H2, for example, 10 seconds has not elapsed. If it is within the timeout, that is, within the monitoring time, the process returns to step H3, and if it is not within the timeout, that is, within the monitoring time, the process is terminated.

  FIG. 16 is a flowchart of the confirmed ID storage array securing process called from the automatic setting process shown in FIG. When called in step G2 shown in FIG. 14, the process proceeds to step J1. In step J1, sumi [] is secured / cleared and the process ends. That is, a storage area for storing the confirmed ID storage array sumi [] is secured in the storage unit 11, the storage area is cleared to NULL, and the process ends.

  FIG. 17 is a flowchart of the end ID storage array securing process called from the automatic setting process shown in FIG. When called in step G3 shown in FIG. 14, the process proceeds to step K1. In step K1, haji [] is secured / cleared and the process ends. That is, a storage area for storing the end ID storage array haji [] is secured in the storage unit 11, the storage area is cleared to NULL, and the process ends.

  FIG. 18 is a flowchart of an end ID search process called from the automatic setting process shown in FIG. When called in step G4 shown in FIG. 14, the process proceeds to step L1. In step L1, “haji_count = 0” is set. That is, the number haji_count of monitors without a monitor adjacent to the left side and the upper side is cleared to “0”. In step L2, “c = 0” is set. That is, the piece number “c” of the array to be checked in the piece array is cleared to “0”. In the figure, “c” is also referred to as “C”.

  In step L3, it is determined whether or not piece [c] [1] = NULL & piece [c] [2] = NULL. That is, it is determined whether or not the monitor of the array to be checked is a monitor without a monitor adjacent to the left side and the upper side. If piece [c] [1] = NULL & piece [c] [2] = NULL, that is, if the monitor of the array to be checked is a monitor without a monitor adjacent to the left side and the upper side, the process proceeds to step L6, and piece [ If c] [1] = NULL & piece [c] [2] = NULL, that is, if the monitor in the array to be checked is a monitor with a monitor adjacent to the left side or the upper side, the process proceeds to step L4. In step L4, “c = c + 1” is set. That is, “1” is added to the piece number “c” of the array to be checked in the piece array. In step L5, it is determined whether c <total. That is, it is determined whether or not the value of the piece number “c” of the array to be checked in the piece array is smaller than the total number of monitors. If c <total, that is, if the value of the piece number “c” of the array to be checked in the piece array is smaller than the total number of monitors, the process returns to step L3. If c <total is not satisfied, that is, the piece array. If the value of the piece number “c” of the array to be checked is not smaller than the total number of monitors, the process ends.

  In step L6, “haji [haji_count] = piece [c] [0]”. That is, the client ID of the monitor without the adjacent monitor on the left side and the upper side is registered in the haji_countth of the end ID storage array. In step L7, “haji_count = haji_count + 1” is set, and the process proceeds to step L4. That is, “1” is added to the number haji_count of monitors without a monitor adjacent to the left side and the upper side, and the process proceeds to Step L4.

  FIG. 19 is a flowchart of the first half of the map storage process called from the automatic setting process shown in FIG. In the map storing process, a block constituted by adjacent monitors is determined and a map of the monitor constituting each block is created. When called in step G7 shown in FIG. 14, the process proceeds to step M1.

  In step M1, “count = 0, MM = 100, NN = 100, cc = 0” is set. First, the counter count for counting the number of monitors in the block is cleared to “0”. Next, for one block, the value MM indicating the position of the vertical candidate for arranging the monitor, the value “100” indicating the vertical position for arranging the monitor first, and the horizontal candidate for arranging the monitor A value “100” indicating the horizontal position where the monitor is first placed is set to the value NN indicating the position of the monitor. In this example, the value of the position in the vertical direction and the horizontal direction at which the monitor is initially arranged is set to “100”, but it is not limited to this value. Further, the counter cc for confirming whether or not the monitor has returned to the first monitor is cleared to “0”.

  In step M2, “mat [block] [0] [0] to mat [block] [254] [254] = NULL, temp = 0” is set. That is, each element of the three-dimensional array mat representing the map for each block is initialized to “NULL”, and temp is cleared to “0”. “block” is a counter for counting the number of blocks. The initial value is “0” and is the first element of the mat array. The second element of the mat array indicates the vertical position of the monitor, and the third element of the mat array indicates the vertical position of the monitor. In streaming, IDs that can be flowed in the same segment are “0” to “254”. In this example, the range of the second and third elements of the mat array is “0” to “254”. However, the present invention is not limited to this. Since the range of the second and third elements of the mat array is “0” to “254”, a position of 255 is prepared as a monitor position in both vertical and horizontal directions, and each monitor is arranged in a 255 × 255 cell. Is set. In the figure, “mat” is also referred to as “Mat”, and “temp” is also referred to as “Temp”.

  In step M3, “next confirmation ID = haji [BB]” is set. That is, the client ID of the monitor to be confirmed next is the confirmed ID registered at the array position indicated by the value “BB” in the end ID storage array haji []. That is, among the monitors registered in the end ID storage array as monitors without the left and upper adjacent monitors, the client ID registered at the array position indicated by the value “BB” is used.

  In step M4, “current ID = next confirmation ID, next confirmation ID = NULL”. That is, the client ID of the monitor for confirming whether there is a current ID, that is, whether there is an adjacent monitor, is the client ID indicated by “next confirmation ID”, and then initializes “next confirmation ID” to “NULL”. To do. In step M5, "sumi [count] = current ID, current ID's piece [] [5] = 0" is set. That is, the client ID indicated by the current ID is registered in the confirmed ID storage array sumi [], and the check item of the piece array of the client ID indicated by the current ID is set to “0”, that is, confirmed.

  In step M6, “M = MM, N = NN”. That is, the value of the pointer M indicating the vertical position of the map is set as the value of MM, and the value of the pointer N indicating the horizontal position of the map is set as the value of NN. In step M7, an array including the current ID is extracted from piece [0] [0] to piece [total-1] [0]. In step M8, “mat [block] [M] [N] = piece of current ID piece [] [0]” is set. In other words, the vertical Mth and horizontal Nth positions of the map are set as client IDs indicated by the current ID.

  In step M9, an upper adjacent process described later for checking whether there is an adjacent monitor on the upper side is called. In step M10, a left adjacency process to be described later for checking whether there is an adjacent monitor on the left side is called. In step M11, a lower adjacent process to be described later for checking whether there is an adjacent monitor on the lower side is called. In step M12, a right adjacent process described later for checking whether there is an adjacent monitor on the right side is called. In Step M13, it is determined whether or not “next confirmation ID” = NULL. If the “next confirmation ID” is NULL, that is, if the monitor to be confirmed next is not in the adjacent monitor, the process proceeds to step M20 shown in FIG. 20, and if the “next confirmation ID” is not NULL, that is, If the monitor to be checked next is in the adjacent monitor, the process proceeds to step M14. In step M14, “count = count + 1” is set, and the process returns to step M4. That is, “1” is added to the counter count for counting the number of monitors in the block, and the process returns to step M4.

  FIG. 20 is a flowchart of the latter half of the map storage process called from the automatic setting process shown in FIG. If it is determined in step M13 illustrated in FIG. 19 that the “next confirmation ID” is NULL, the process proceeds to step M20.

  In step M20, “cc = count” is set. That is, the counter cc for confirming whether or not the first monitor has been returned is set to the value of the counter count for counting the number of monitors in the block. In step M21, it is determined whether or not cc <0. If cc <0, that is, return to the first monitor, the process ends. If not cc <0, that is, if the first monitor is not returned, the process proceeds to step M22.

  In step M22, it is determined whether or not the piece [] [1] = NULL of the sumi [cc] ID. That is, it is determined whether or not the upper ID in the piece array of the client ID registered in sumi [cc] is NULL among the client IDs registered in the confirmed ID storage array sumi []. When the piece [] [1] of the sumi [cc] ID is not NULL, that is, when there is an adjacent monitor on the upper side, the process proceeds to step M27, and the piece [] [1] = NULL of the sumi [cc] ID. If there is no adjacent monitor on the upper side, the process proceeds to step M23.

  In step M23, it is determined whether or not the piece [] [2] = NULL of the sumi [cc] ID. That is, it is determined whether or not the left ID of the piece array of the client ID registered in sumi [cc] is NULL among the client IDs registered in the confirmed ID storage array sumi []. When the piece [] [2] of the sumi [cc] ID is not NULL, that is, when there is an adjacent monitor on the left side, the process proceeds to step M28, and the piece [] [2] = NULL of the sumi [cc] ID. If there is no adjacent monitor on the left side, the process proceeds to step M24.

  In step M24, it is determined whether or not the piece [] [3] = NULL of the sumi [cc] ID. That is, it is determined whether or not the ID below the piece array of the client ID registered in sumi [cc] is NULL among the client IDs registered in the confirmed ID storage array sumi []. When the piece [] [3] of the sumi [cc] ID is not NULL, that is, when there is an adjacent monitor on the lower side, the process proceeds to step M29, and the piece [] [3] = NULL of the sumi [cc] ID. If there is, that is, if there is no adjacent monitor on the lower side, the process proceeds to step M25.

  In step M25, it is determined whether or not the piece [] [4] = NULL of the sumi [cc] ID. That is, it is determined whether or not the right ID in the piece array of the client ID registered in sumi [cc] is NULL among the client IDs registered in the confirmed ID storage array sumi []. When the piece [] [4] of the sumi [cc] ID is not NULL, that is, when there is an adjacent monitor on the right side, the process proceeds to Step M30, and the piece [] [4] = NULL of the sumi [cc] ID. If there is no adjacent monitor on the right side, the process proceeds to step M26. In Step M26, “cc = cc−1” is set. That is, “1” is subtracted from the counter cc for confirming whether or not the monitor has returned to the first monitor, and the process returns to step M21.

  In Step M27, “next confirmation ID = piece [] [1] having an ID of sumi [cc]” is set, and the process proceeds to Step M31. That is, “next confirmation ID” is set as the client ID of the upper ID in the piece array of the client ID registered in sumi [cc], and the process proceeds to step M31. In step M28, “next confirmation ID = piece [] [2] having ID of sumi [cc]” is set, and the process proceeds to step M31. That is, “next confirmation ID” is set as the client ID of the left ID of the piece array of the client ID registered in sumi [cc], and the process proceeds to step M31. In step M29, “next confirmation ID = piece [] [3] having ID of sumi [cc]” is set, and the process proceeds to step M31. That is, “next confirmation ID” is set as the client ID of the lower ID of the client ID registered in sumi [cc], and the process proceeds to step M31. In Step M30, “next confirmation ID = piece [] [4] having ID of sumi [cc]” is set, and the process proceeds to Step M31. That is, “next confirmation ID” is set as the client ID of the right ID in the piece array of the client ID registered in sumi [cc], and the process proceeds to step M31.

  In step M31, a search is made for mat [block] [M] [] and mat [block] [] [N] of mat [block] having “next confirmation ID”. That is, the vertical position M and the horizontal position N where the “next confirmation ID” is located are searched from the block including the client ID indicated by the “next confirmation ID”. Specifically, first, the position of the monitor with the ID of sumi [cc] is searched from the map of the registered blocks, and then the monitor with the ID of sumi [cc] is searched based on the searched position. Based on the relative positional relationship between the position and the monitor position of the client ID indicated by the “next confirmation ID”, the position of the monitor of the client ID indicated by the “next confirmation ID” is determined, and the vertical position thereof Is M, and the horizontal position is N.

  In Step M32, “MM = M, NN = N” is set, and the process returns to Step M14 shown in FIG. That is, the value of MM is the value of M, and the value of NN is the value of N. MM and NN are set to values representing positions in the monitor map to be checked next, that is, the values of M and N found in step M31, and the process returns to step M14 shown in FIG.

  FIG. 21 is a flowchart of the upper adjacent process called from the map storage process shown in FIG. The upper adjacent process confirms whether there is an adjacent monitor on the upper side. When called in step M9 shown in FIG. 19, the process proceeds to step N1.

  In step N1, it is determined whether or not the current ID piece [] [1] is not NULL. If the current ID piece [] [1] is not NULL, that is, if there is a client ID in the ID above the current ID piece array, the process proceeds to step N2, and if the current ID piece [] [1] is NULL, That is, if there is no client ID in the ID above the current ID piece array, the process ends.

  In Step N2, it is determined whether or not the client ID of the current ID piece [] [1] is in piece [0] [0] to piece [total-1] [0]. That is, it is determined whether or not the client ID indicated by the upper ID of the current ID piece array is within the own ID of the piece array. When the client ID of the current ID piece [] [1] is in piece [0] [0] to piece [total-1] [0], that is, the client ID indicated by the upper ID of the current ID piece array is piece. If it is in the own ID of the array, the process proceeds to step N3, where the client ID of the current ID piece [] [1] is not in piece [0] [0] -piece [total-1] [0], that is, If the client ID indicated by the upper ID in the piece array of the current ID is not in the own ID of the piece array, the process ends.

  In Step N3, it is determined whether or not the target piece [] [5] is not “0”. That is, it is determined whether or not the check item of the piece array of the client ID indicated by the upper ID is “0”. If the target piece [] [5] is not “0”, that is, if the check item of the piece array of the client ID indicated by the upper ID has not been confirmed, the process proceeds to Step N4, and the target piece [] [5] is “0”. ", That is, if the check item of the piece array of the client ID indicated by the upper ID has been confirmed, the process ends.

  In step N4, it is determined whether mat [block] [M-1] [N] is not NULL. That is, it is determined whether or not a client ID is set at a position on the map. If mat [block] [M-1] [N] is not NULL, that is, if the client ID is set at one position on the map, the process proceeds to Step N7, where mat [block] [M-1] If [N] is NULL, that is, if the client ID is not set at the position one higher on the map, the process proceeds to Step N5. In Step N5, “target piece [] [5] = 2” is set. That is, the check item of the piece array of the client ID indicated by the upper ID is set to “2”. “2” indicates that it is adjacent to a monitor whose arrangement has been confirmed and has not yet been confirmed. In step N6, the current ID piece [] [1] is set in mat [block] [M-1] [N]. That is, the client ID of the upper ID of the current ID piece array is set at a position one level higher on the map.

  In step N7, piece [] [1] having the current ID is substituted for TID, and piece [] [1] having the current ID is set to NULL. That is, the upper ID of the current ID piece array is set to NULL, and the search has been completed. The TID is a work for temporarily storing a client ID that should be the next confirmation ID. In step N8, piece [] [3] having the target ID is set to NULL. In other words, the lower ID of the piece array of “next confirmation ID” is set to NULL, and the search has been completed. In Step N9, “next confirmation ID = TID” is set. That is, the “next confirmation ID” is the client ID of the upper ID that was in the piece array of the current ID. In Step N10, “MM = M−1, NN = N” is set, and the process ends. That is, MM and NN are set to values representing the position in the monitor map to be checked next, that is, the position one level higher, and the process ends.

  FIG. 22 is a flowchart of the left adjacent process called from the map storage process shown in FIG. The left adjacency process checks whether there is an adjoining monitor on the left side. When called at step M10 shown in FIG. 19, the process proceeds to step P1.

  In Step P1, it is determined whether or not the piece [] [2] of the current ID is NULL. If the current ID piece [] [2] is not NULL, that is, if there is a client ID in the left ID of the current ID piece array, the process proceeds to step P2, and if the current ID piece [] [2] is NULL, That is, if there is no client ID in the left ID of the current ID piece array, the process ends.

  In Step P2, it is determined whether or not the client ID of the current ID piece [] [2] is in piece [0] [0] to piece [total-1] [0]. That is, it is determined whether or not the client ID indicated by the left ID of the current ID piece array is in its own ID of the piece array. When the client ID of the current ID piece [] [2] is in piece [0] [0] to piece [total-1] [0], that is, the client ID indicated by the left ID of the current ID piece array is the piece ID. If it is in the own ID of the array, the process proceeds to Step P3, and if the client ID of the current ID piece [] [2] is not in piece [0] [0] to piece [total-1] [0], that is, If the client ID indicated by the left ID in the piece array of the current ID is not in the own ID of the piece array, the process ends.

  In Step P3, it is determined whether or not the target piece [] [5] is not “0”. That is, it is determined whether or not the check item of the piece array of the client ID indicated by the left ID is “0”. If the target piece [] [5] is not “0”, that is, if the check item of the piece array of the client ID indicated by the left ID has not been confirmed, the process proceeds to Step P4, and the target piece [] [5] is “0”. ", That is, if the check item of the piece array of the client ID indicated by the left ID has been confirmed, the process ends.

  In step P4, it is determined whether mat [block] [M] [N-1] is not NULL. That is, it is determined whether or not the client ID is set to the left one position on the map. If mat [block] [M] [N-1] is not NULL, that is, if the client ID is set to the left one position on the map, the process proceeds to Step P7, and mat [block] [M] [N -1] is NULL, that is, if the client ID is not set to the left one position on the map, the process proceeds to Step P5. In Step P5, “target piece [] [5] = 2” is set. That is, the check item of the piece array of the client ID indicated by the left ID is set to “2”. “2” indicates that it is adjacent to a monitor whose arrangement has been confirmed and has not yet been confirmed. In step P6, the current ID piece [] [2] is set in mat [block] [M] [N-1]. That is, the client ID of the left ID of the piece array of the current ID is set to the left one position on the map.

  In step P7, piece [] [2] having the current ID is substituted for TID, and piece [] [2] having the current ID is set to NULL. That is, the left ID of the current ID piece array is set to NULL, and the search is completed. In step P8, piece [] [4] having the target ID is set to NULL. That is, the right ID of the piece array of “next confirmation ID” is set to NULL, and the search is completed. In Step P9, it is determined whether or not “next confirmation ID” is set. If “next confirmation ID” is set, the process ends. If “next confirmation ID” is not set, the process proceeds to step P10. In other words, if “next confirmation ID” has already been set in the adjacent processing shown in FIG. 21, the update of “next confirmation ID” is skipped.

  In Step P10, “next confirmation ID = TID” is set. That is, the “next confirmation ID” is set as the client ID of the left ID that was in the piece array of the current ID. In Step P11, “MM = M, NN = N−1” is set, and the process ends. That is, MM and NN are set to values representing the position in the monitor map to be checked next, that is, the position one place to the left, and the process ends.

  FIG. 23 is a flowchart of the lower adjacent process called from the map storing process shown in FIG. The lower adjacency process checks whether there is an adjacent monitor on the lower side. When called in step M11 shown in FIG. 19, the process proceeds to step Q1.

  In step Q1, it is determined whether or not the current ID piece [] [3] is not NULL. If the current ID piece [] [3] is not NULL, that is, if there is a client ID in the lower ID of the current ID piece array, the process proceeds to step Q2, and if the current ID piece [] [3] is NULL, That is, if there is no client ID in the lower ID of the current ID piece array, the process ends.

  In step Q2, it is determined whether or not the client ID of the current ID piece [] [3] is in piece [0] [0] to piece [total-1] [0]. That is, it is determined whether or not the client ID indicated by the lower ID of the current ID piece array is within the own ID of the piece array. If the client ID of the current ID piece [] [3] is in piece [0] [0] to piece [total-1] [0], that is, the client ID indicated by the lower ID of the current ID piece array is the piece ID. If it is in the own ID of the array, the process proceeds to step Q3, and the client ID of the current ID piece [] [3] is not in piece [0] [0] to piece [total-1] [0], that is, If the client ID indicated by the lower ID of the current ID piece array is not within the own ID of the piece array, the processing ends.

  In step Q3, it is determined whether or not the target piece [] [5] is not “0”. That is, it is determined whether or not the check item of the piece array of the client ID indicated by the lower ID is “0”. If the target piece [] [5] is not “0”, that is, if the check item of the piece array of the client ID indicated by the lower ID has not been confirmed, the process proceeds to step Q4, and the target piece [] [5] is “0”. ", That is, if the check item of the piece array of the client ID indicated by the lower ID has been confirmed, the process ends.

  In step Q4, it is determined whether mat [block] [M + 1] [N] is not NULL. That is, it is determined whether or not the client ID is set at the next lower position on the map. If mat [block] [M + 1] [N] is not NULL, that is, if the client ID is set at the next lower position on the map, the process proceeds to step Q7, where mat [block] [M + 1] [N] If it is NULL, that is, if the client ID is not set at the next lower position on the map, the process proceeds to step Q5. In Step Q5, “target piece [] [5] = 2” is set. That is, the check item of the piece array of the client ID indicated by the lower ID is set to “2”. “2” indicates that it is adjacent to a monitor whose arrangement has been confirmed and has not yet been confirmed. In step Q6, the current ID piece [] [3] is set in mat [block] [M + 1] [N]. That is, the client ID of the lower ID in the piece array of the current ID is set at the position one level lower on the map.

  In step Q7, piece [] [3] having the current ID is substituted for TID, and piece [] [3] having the current ID is set to NULL. That is, the lower ID of the current ID piece array is set to NULL, and the search is completed. In step Q8, piece [] [1] having the target ID is set to NULL. That is, the upper ID of the piece array of “next confirmation ID” is set to NULL, and the search has been completed. In step Q9, it is determined whether or not “next confirmation ID” is set. If “next confirmation ID” is set, the process ends. If “next confirmation ID” is not set, the process proceeds to step Q10. That is, if “next confirmation ID” is already set in the upper adjacent process shown in FIG. 21 or the left adjacent process shown in FIG. 22, the update of “next confirmation ID” is skipped.

  In step Q10, “next confirmation ID = TID” is set. That is, the “next confirmation ID” is set as the lower ID client ID in the current ID piece array. In step Q11, the process ends with “MM = M + 1, NN = N”. In other words, MM and NN are set to values representing the position in the monitor map to be checked next, that is, the position one level below, and the process ends.

  FIG. 24 is a flowchart of the right adjacent process called from the map storage process shown in FIG. The right adjacency process checks whether there is an adjacent monitor on the right side. When called in step M12 shown in FIG. 19, the process proceeds to step R1.

  In step R1, it is determined whether or not the current ID piece [] [4] is not NULL. If the current ID piece [] [4] is not NULL, that is, if there is a client ID in the right ID of the current ID piece array, the process proceeds to step R2, and if the current ID piece [] [4] is NULL, That is, if there is no client ID in the right ID of the current ID piece array, the process ends.

  In step R2, it is determined whether or not the client ID of the current ID piece [] [4] is in piece [0] [0] -piece [total-1] [0]. That is, it is determined whether or not the client ID indicated by the right ID of the current ID piece array is in the own ID of the piece array. If the client ID of the current ID piece [] [4] is in piece [0] [0] to piece [total-1] [0], that is, the client ID indicated by the right ID of the current ID piece array is piece. If it is in the own ID of the array, the process proceeds to step R3, where the client ID of the current ID piece [] [4] is not in piece [0] [0] -piece [total-1] [0], that is, If the client ID indicated by the right ID in the piece array of the current ID is not in the own ID of the piece array, the processing ends.

  In Step R3, it is determined whether or not the target piece [] [5] is not “0”. That is, it is determined whether or not the check item of the piece array of the client ID indicated by the right ID is “0”. If the target piece [] [5] is not “0”, that is, if the check item of the piece array of the client ID indicated by the right ID has not been confirmed, the process proceeds to step R4, and the target piece [] [5] is “0”. ", That is, if the check item of the piece array of the client ID indicated by the right ID has been confirmed, the process ends.

  In step R4, it is determined whether mat [block] [M] [N + 1] is not NULL. That is, it is determined whether or not the client ID is set to the right one position on the map. If mat [block] [M] [N + 1] is not NULL, that is, if the client ID is set to the right one position on the map, the process proceeds to step Q7, where mat [block] [M] [N + 1] If it is NULL, that is, if the client ID is not set to the right one position on the map, the process proceeds to step Q5. In Step Q5, “target piece [] [5] = 2” is set. That is, the check item of the piece array of the client ID indicated by the right ID is set to “2”. “2” indicates that it is adjacent to a monitor whose arrangement has been confirmed and has not yet been confirmed. In step R6, the current ID piece [] [4] is set in mat [block] [M] [N + 1]. That is, the client ID of the right ID in the piece array of the current ID is set to the right one position on the map.

  In step R7, piece [] [4] having the current ID is substituted for TID, and piece [] [4] having the current ID is set to NULL. That is, the right ID of the current ID piece array is set to NULL, and the search is completed. In step R8, piece [] [2] having the target ID is set to NULL. That is, the left ID of the piece array of “next confirmation ID” is set to NULL, and the search is completed. In step R9, it is determined whether or not “next confirmation ID” is set. If “next confirmation ID” is set, the process ends. If “next confirmation ID” is not set, the process proceeds to step R10. That is, if the “next confirmation ID” is already set in the upper adjacent process shown in FIG. 21, the left adjacent process shown in FIG. 22, or the lower adjacent process shown in FIG. The update of “next confirmation ID” is skipped.

  In step R10, “next confirmation ID = TID” is set. That is, the “next confirmation ID” is the client ID of the right ID that was in the piece array of the current ID. In Step R11, “MM = M, NN = N + 1” is set, and the process ends. That is, MM and NN are set to values indicating the position in the monitor map to be checked next, that is, the position to the right of one, and the process ends.

  FIG. 25 is a flowchart of an effective block selection process called from the position setting process shown in FIG. In the effective block selection process, a block for displaying content is selected. When called in step F8 shown in FIG. 10, the process proceeds to step S1.

  In step S1, it is determined whether block> 0. That is, when block = 0, since the number of blocks is “1”, it is determined whether or not the number of blocks is larger than “1”. If block> 0, that is, if the number of blocks is larger than “1”, the block is divided into two or more blocks. Therefore, the process proceeds to step S4. If block> 0 is not satisfied, that is, the number of blocks is “1”. If not, the process proceeds to step S2. In step S2, block = 0 is validated. That is, the block number is “1” with block = 0. In step S3, it is determined whether or not the selected block is configured as a square. That is, it is determined whether or not the shape of the selected and effective block, that is, the shape formed by the monitor screen that forms the block is a quadrangle. If the selected block is configured as a square, that is, if the shape of the selected block is a square, the process ends. If the selected block is not configured as a square, that is, if the selected block is not a square, the process proceeds to step S6. When the shape of the selected block is a quadrangle, the client ID of the monitor included in the block is stored in the storage unit 11.

  In step S4, a block is selected. That is, one block for displaying content is selected from a plurality of blocks. For example, the blocks are selected by assigning a block number to a plurality of blocks in the monitor configuration automatically set in the automatic setting process in step F7 shown in FIG. This is selected by specifying a block number with an input device (not shown) of the server 10. In step S5, the selected block is validated and the process proceeds to step S3. In step S6, the effective range is selected and the process ends. For example, the monitor is selected so that the shape formed by the screen of the selected monitor forms a quadrangle, and the process ends. The monitor selection may be selected, for example, by specifying a client ID with an input device (not shown) of the server 10 or may be selected by instructing a monitor set on the configuration setting screen 40. The selected block number and the client ID of the selected monitor are stored in the storage unit 11. The server 10 transmits the content to the selected monitor among the monitors constituting the block indicated by the block number stored in the storage unit 11.

  In the above-described embodiment, a client having a quadrangular screen has been described as an example. However, the screen is not limited to a quadrangular shape, and a client having an n-gonal screen such as a triangular shape or a hexagonal shape. Also good. n is a natural number. In that case, of the surfaces constituting the shape of the client, the shape of the surface having the screen is also the same n-gon, and the detector 26 is provided on each side. Furthermore, although the priority order is the order of top, left, bottom, and right, it is not limited to this.

  Further, in the above-described embodiment, the configuration setting method of the display system 1 including a plurality of clients having a screen has been described. This configuration setting method is a configuration setting method for the configuration of a plurality of screens included in the display system 1. Can be applied as

  In this way, priority is assigned to each side, and for example, a client 20 that is a plurality of display units having side surfaces forming a screen in a polygon of n sides where n is a natural number, and connected to adjacent display units In setting the configuration of, for example, the display system 1, which is a display device in which the detection unit 26, which is a possible connection unit, for example, is constituted by a plurality of display units provided on each side, is first a first display unit setting means. For example, one display unit from among the display units in which the number of consecutive sides that are not connected to other display units by the connection unit by the server control unit 14 is equal to or greater than the value obtained by dividing n by 2 Is selected as the first attention display unit, for example, as the monitor of the current ID, and the arrangement position information indicating the arrangement position of the selected display unit is stored in the map of the storage unit 11, for example. That. Next, if there is an unselected display part that has not yet been selected as the attention display part among the display parts connected to the attention display part, the server control part 14 that is the second display part setting means, for example, The unselected display part connected to the edge with the highest priority among the sides to which the selected display part is connected is selected as the new attention display part, and the arrangement position of the display part selected as the new attention display part Is determined from the position of the connection portion to which the new attention display portion is connected among the connection portions of the previous attention display portion, and the arrangement position information indicating the determined arrangement position is stored in the storage portion. The second display unit setting unit is repeatedly operated until the display unit without the unselected display unit among the connected display units becomes the attention display unit, for example, by the server control unit 14 which is the first repetition unit, With configuration setting means By Rutatoeba server control section 14, the configuration of the display section is set based on the stored position information in the storage unit, it is possible to automatically set its configuration. Therefore, if this display device is used, the man-hours for setting the configuration of a plurality of display units can be reduced.

  Further, the configuration setting method of the display system 1 as a display device includes a plurality of, for example, clients 20 that are display units having an n-gonal display surface in which priority is assigned to each side and n is a natural number. In setting the configuration of the display system 1, for example, a display device in which each display unit is provided adjacent to each other so that at least one side of the display and one side of the other display surface are adjacent to each other, For example, in the first half of the edge ID search process and the map storage process, which is the display unit selection process, the number of sides that are adjacent to one side of the other display surface and are not opposed to each other and that are adjacent to each other is n. One display unit is selected as a first attention display unit, for example, a monitor of the current ID from among the display units having a value equal to or greater than the value obtained by dividing 2 by 2, and the arrangement position information indicating the arrangement position of the selected display unit Stored in the map storage unit and is for example storage unit 11. Next, when there is an unselected display portion that has not yet been selected as the attention display portion among the display portions adjacent to the attention display portion, for example, in the map storage process that is the first repetition process, the display surface of the attention display portion is displayed. Among each side, an unselected display part having a display surface having a side adjacent to and facing the highest priority side is selected as a new attention display part, and the arrangement of the display part selected as the new attention display part The second display unit selection step of determining the position from the arrangement position of the display unit that is set as the attention display unit immediately before the new attention display unit, and further storing the arrangement position information representing the determined arrangement position in the storage unit For example, the process of the first half of the map storage process is repeated until an unselected display part in which all of the adjacent display parts have already been selected as the attention display part is selected as the new attention display part. Ah For example, in the position setting process, since for setting the configuration of the display unit on the basis of the position information stored in the storage unit, it is possible to automatically set its configuration. Accordingly, by using this configuration setting method in a display device including a plurality of display units having connection units that connect adjacent display units, the man-hours for setting the configuration can be reduced.

  Furthermore, in the first display part selection process, for example, the first half of the end ID search process and the map storage process, and the second display part selection process, for example, the first part of the map storage process, For example, the confirmed ID storage array which is the order information indicating the order in which the arrangement position information of the selected display unit is stored is further stored in the storage unit 11 such as the storage unit, and the second display unit selecting step is performed adjacently. After repeating until all unselected display parts that have already been selected as attention display parts are selected as new attention display parts, the first repetition process is, for example, a third repetition process included in the map storage process Then, each display unit is selected as a new attention display unit in the reverse order to the order indicated by the sequence information stored in the storage unit, and the display unit adjacent to the selected display unit is not yet selected. When there is a selection display section, this unselected display section is selected as a new attention display section, and an unselected display section in which all of the adjacent display sections are already selected as the attention display section is selected as a new attention display section. Until the selection, the second repeating step of repeating the second display portion selection step is performed. The display portion in which the placement position information is first stored in the storage portion is selected as the attention display portion, and the placement position information is stored in the first place. Since the unselected display part adjacent to the displayed display part is repeated until it is selected as the attention display part, after the display parts are sequentially selected until there are no adjacent display parts, the unselected display part remains because the priority is low. However, when checking whether or not the attention display unit is selected by returning to the first attention display unit in the order reverse to the order indicated by the order information stored in the storage unit, the remaining unselected display unit is selected. Can It can be set dynamically its configuration. Therefore, even if the configuration constituted by a plurality of display units is any irregular configuration, the man-hours for setting the configuration can be reduced.

  In the embodiment described above, the program is stored in the storage unit 11 of the server 10 included in the display system 1, for example, a storage device such as a semiconductor memory or a hard disk device, but is not limited to these storage devices. The program may be recorded on a computer-readable recording medium. The recording medium may be a recording medium that can be read by providing a program reading device as an external storage device (not shown) and inserting the recording medium therein, or may be a storage device of another device. .
