     Hereinafter, the exemplary embodiments of the present disclosure will be described with reference to the drawings. 
     Exemplary Embodiment 
     A data input system of the present disclosure will be described below. 
     [1-1. Configuration of Data Input System] 
       FIG. 1  is a diagram showing a configuration of data input system  100 . Data input system  100  is configured by signage data input device  101 , signage server  102 , and signage display device  103 . 
     The communication of signage server  102  and signage display device  103  is established by transmitting a display device ID, which is information with which signage display device  103  can be identified. Furthermore, a secure communication method may be adopted in the communication to prevent impersonation and the like. 
     Signage server  102  sends signage data to be displayed to signage display device  103 . Signage display device  103  displays the received signage data. Signage display device  103  transmits a playback log, which indicates the displayed content information, to signage server  102  in correspondence with the display of the signage data. In this case, the display device ID, which is the information with which the signage display device can be identified, may be transmitted with the playback log. 
     Signage server  102  receives the playback log from signage display device  103 , and transmits an editable item in conjunction with the displayed signage data to signage data input device  101  based on the playback log. The communication of signage server  102  and signage data input device  101  is established by transmitting a terminal ID, which enables signage data input device  101  to be identifiable. Furthermore, a secure communication method may be adopted in the communication to prevent impersonation and the like. 
     Signage data input device  101  receives the editable item from signage server  102 . The editable item is displayed so that the content information displayed on signage display device  103  can be edited according to the received editable item. When editing is carried out on the displayed item, the edited content information is transmitted to signage server  102 . 
     Upon receipt of the edited content information from signage data input device  101 , signage server  102  transmits the received edited content information to signage display device  103 . 
     Signage display device  103  updates the display-content information according to the received edited signage data. In this case, the update log indicating that update has been carried out is transmitted to signage server  102 . 
     [1-2. Display and Editing of Signage Data] 
       FIG. 2  is a view showing one example in which signage display device  103  displays the signage data received from signage server  102 . Specifically,  FIG. 2  shows one example in which the content indicating a menu of “Manpuku Diner”, which is a restaurant, is displayed as the signage data. The contents are displayed in the order of DS  201 , DS  202 , DS  203 , DS  204 , DS  205 , and DS  206 . DS  201 , DS  202 , and DS  203  are displays for “Pork Cutlet Set Meal”, which is one of the menus. In DS  201 , restaurant name  210  of “Manpuku Diner”, which indicates the name of the restaurant, and picture  211  of “Pork Cutlet Set Meal” are displayed for three seconds, for example. In DS  202 , menu name  212  of “Pork Cutlet Set Meal” is added to the display of DS  201 , and displayed for three seconds, for example. In DS  203 , price  213  of “735 yen”, which indicates a price, is added to the display of DS  202 , and displayed for three seconds, for example. The subsequent DS  204 , DS  205 , and DS  206  are displays for “Fried Calamari Set Meal”, which is one of the menus. DS  203 , which is the display of “Pork Cutlet Set Meal”, is switched to the display of “Fried Calamari Set Meal”. In DS  204 , restaurant name  210  of “Manpuku Diner”, which indicates the name of the restaurant, and picture  214  of “Fried Calamari Set Meal” are displayed for three seconds, for example. In DS  205 , menu name  215  of “Fried Calamari Set Meal” is added to the display of DS  204 , and displayed for three seconds, for example. In DS  206 , price  216  of “630 yen”, which indicates the price, is added to the display of DS  205 , and displayed for three seconds, for example. Thereafter, DS  206 , which is the display of “Fried Calamari Set Meal”, is returned to the display of “Pork Cutlet Set Meal”. One menu is thus configured such that the picture, the menu name, and the price are each independently editable. 
       FIG. 3A  is a view showing one example of signage data format  301 , and  FIG. 3B  is a view showing one example of signage data  302  in which the signage data described in  FIG. 2  is defined with signage data format  301  of  FIG. 3A . 
     In signage data format  301 , the description of “content name” that identifies the content of the signage is made first. Signage data format  301  is then configured by “screen name definition” that configures the content, “constituent definition” that configures the screen, and “playback time definition”. The “constituent definition” defines the constituents configuring one screen. A plurality of constituents can be defined. The editable constituent can be identified by underlining. The “playback time definition” defines the playback order and the playback time of each constituent using the constituents defined in the “constituent definition”. 
     The constituent defined in the “constituent definition” and not defined in the “playback time definition” may be always displayed during the playback of the screen. 
     The “playback time definition” may define not only the playback order and the playback time of each constituent, but also wipe, scroll, and the like as a playback effect, for example, an effect of screen switching. 
     In signage data  302  of  FIG. 3B , the content with the content name “Manpuku Diner” is defined. “Pork Cutlet Set Meal” and “Fried Calamari Set Meal” are defined as the screen names. In the definition of the screen name “Pork Cutlet Set Meal”, “picture 10”, “text 11”, “text 12”, and “text 01” are defined as the constituent definitions, and “picture 10”, “text 11”, and “text 12” are underlined so that such constituents are editably defined. “Picture 10” corresponds to picture  211  of “Pork Cutlet Set Meal” in  FIG. 2 , “text 11” corresponds to menu name  212  of “Pork Cutlet Set Meal” in  FIG. 2 , “text 12” corresponds to price  213  of “735 yen” in  FIG. 2 , and “text 01” corresponds to restaurant name  210  of “Manpuku Diner” in  FIG. 2 .

ED  202  is provided for editing the text, and includes a region for inputting the text and also includes an “edit” button for starting the editing. “Pork Cutlet Set Meal”, which is the current text, is displayed in the region for inputting the text. The current text can be partially corrected. 
     When DS  203  is displayed on signage display device  103 , the displayed content information is transmitted from signage display device  103  to signage server  102  as a playback log. Signage server  102  that received the playback log transmits price  213  of “735 yen”, which is an editable item of DS  203 , to signage data input device  101 . Signage data input device  101  displays ED  203 , which is an edit screen for editing price  213  of “735 yen”. ED  203  is provided for editing the text, and includes a region for inputting the text and also includes an “edit” button for starting the editing. 
     In  FIG. 5 , the left side of the figure is a part of signage data  302  displayed by signage display device  103  of  FIG. 2 . The right side of the figure is the edit screen of signage data input device  101 . When DS  203  is displayed on signage display device  103 , the displayed content information is transmitted from signage display device  103  to signage server  102  as a playback log. Signage server  102  that received the playback log transmits price  213  of “735 yen”, which is an editable item of DS  203 , to signage data input device  101 . Signage data input device  101  displays ED  203 , which is the edit screen for editing price  213  of “735 yen”. ED  203  is provided for editing the text, and includes a region for inputting the text and also includes an “edit” button for starting the editing. 
     The user presses the “edit” button of ED  203  to update price  213  of “735 yen”. When the “edit” button is pressed, the display screen is switched to ED  203 A. The difference with ED  203  is that the “edit” button is changed to a “confirm” button and a “return” button. The editing of the text is carried out in the region for inputting the text, and the “confirm” button is pressed to confirm editing, and the “return” button is pressed to cancel editing. In ED  203 A, “735 yen” is edited to “630 yen”. When the “edit” button is pressed in ED  203 , notification that the “edit” button is pressed is made from signage data input device  101  to signage server  102 , and signage server  102  stops the transmission of the editable item to signage data input device  101  until notification is made that the “confirm” button or “return” button is pressed in ED  203 A. 
     The display of signage display device  103  is continued even while the edit screen of ED  203 A is being displayed. When the “confirm” button is pressed in ED  203 A, DS  204  is assumed to be displayed on signage display device  103 . Signage server  102  then resumes the transmission of the editable item to signage data input device  101 , and thus signage data input device  101  displays ED  204 . 
     In signage data input device  101 , during the editing of the edit screen, notification may be made that editing is being carried out to signage display device  103 , and the display of the signage in signage display device  103  may be stopped. In this case, notification that editing is being carried out may be made from signage server  102  to signage display device  103 . 
     When the “confirm” button is pressed in ED  203 A, signage data input device  101  transmits the edited content information to signage server  102 , and signage server  102  notifies the edited content information to signage display device  103 . Signage display device  103  that received the notification displays DS  203 A, which is an update screen of DS  203 . Price  213  of “735 yen” is updated to price  213 A of “630 yen”. Signage display device  103  transmits an update log indicating that update has been carried out to signage server  102 , and signage server  102  transmits the update-content information and the update time to signage data input device  101 . Signage data input device  101  displays ED  503 , which is an edit screen presenting the update-content information and the update time. 
     [1-3. Configuration of Signage Server] 
     The configuration of signage server  102  will be described below.  FIG. 6  is a function block diagram of signage server  102 . Signage server  102  is configured by log receiving unit  601 , analyzing unit  602 , item transmitting unit  603 , edit instruction receiving unit  604 , updating unit  605 , data transmitting unit  606 , and signage data DB  607 . 
     Log receiving unit  601 , item transmitting unit  603 , edit instruction receiving unit  604 , and data transmitting unit  606  are realized, for example, by a wireless or wired communication device, and a processor that executes a predetermined process. Analyzing unit  602  and updating unit  605  are realized by a processor that executes a predetermined process. Such functions may be realized by one processor, or may be assigned and realized by a plurality of processors. Signage data DB  607  is realized, for example, by an optically-readable or magnetically-readable recording medium. 
     Upon receiving the instruction to start the display of the signage data, data transmitting unit  606  extracts corresponding signage data  302  from signage data DB  607 , and transmits signage data  302  to signage display device  103 . 
     Signage data  302  may be held in advance by signage display device  103 , and may not be transmitted at the same time as the instruction to start the display. 
       FIG. 7  is a flowchart showing the operation of transmission and reception of the log of signage server  102 . 
     Log receiving unit  601  receives the playback log or the update log transmitted from signage display device  103 , and transmits the same to analyzing unit  602 . The operation described in  FIG. 7  is continued during receipt of the playback log or the update log transmitted from signage display device  103 . 
       FIG. 8A  is a view showing a format of the playback log,  FIG. 8B  is a view showing a format of the update log,  FIG. 8C  is a view showing the playback log with respect to the display of DS  201  defined with the format of  FIG. 8A ,  FIG. 8D  is a view showing the playback log with respect to the display of DS  202  defined with the format of  FIG. 8A ,  FIG. 8E  is a view showing the playback log with respect to the display of DS  203  defined with the format of  FIG. 8A ,  FIG. 8F  is a view showing the playback log with respect to the display of DS  204  defined with the format of  FIG. 8A , and  FIG. 8G  is a view showing the update log with respect to the display of DS  203 A defined with the format of  FIG. 8B . 
     The format of the playback log of  FIG. 8A  is defined by the description “playback log”, which represents the playback log, and the “content name”, the “screen name definition”, the “constituent definition”, and the “playback time” of displayed signage data  302 . The format of the update log of  FIG. 8B  is defined by the description “update log”, which represents the update log, and the “content name”, the “screen name definition”, the “constituent definition”, and the “update time” of updated and displayed signage data  302 . A plurality of descriptions can be made in the “constituent definition”. Here, each of the “content name”, the “screen name definition”, and the “constituent definition” corresponds to the “content name”, the “screen name definition”, and the “constituent definition” of signage data format  301 . 
     The playback log of  FIG. 8C  is the playback log with respect to the display of DS  201 , and “Manpuku Diner”, “Pork Cutlet Set Meal”, “(picture 10, text 01)”, and “12:00:00” are described after the description of “playback log”. The playback log of  FIG. 8D  is the playback log with respect to the display of DS  202 , and “Manpuku Diner”, “Pork Cutlet Set Meal”, “text 11”, and “12:00:03” are described after the description of “playback log”. The playback log of  FIG. 8E  is the playback log with respect to the display of DS  203 , and “Manpuku Diner”, “Pork Cutlet Set Meal”, “text 12”, and “12:00:06” are described after the description of “playback log”. The playback log of  FIG. 8F  is the playback log with respect to the display of DS  204 , and “Manpuku Diner”, “Fried Calamari Set Meal”, “(picture 20, text 01)”, and “12:00:07” are described after the description of “playback log”. The update log of  FIG. 8G  is the update log with respect to the display of DS  203 A, and “Manpuku Diner”, “Pork Cutlet Set Meal”, “text 12”, and “12:00:08” are described after the description of “update log”. 
     (S 701 ) Analyzing unit  602  determines whether the received log is the playback log or the update log. When the received log is the playback log (in the case of “playback”), the process proceeds to S 702 . When the received log is the update log (in the case of “update”), the process proceeds to S 704 . 
     (S 702 ) Analyzing unit  602  determines the editable item from the “content name”, the “screen name definition”, and the “constituent definition” included in the playback log, and corresponding signage data  302  stored in signage data DB  607 . For example, when the playback log is the case of  FIG. 8C , “picture 10” is the editable item compared with signage data  302 . When the playback log is the case of  FIG. 8D , “text 11” is the editable item, when the playback log is the case of  FIG. 8E , “text 12” is the editable item, and when the playback log is the case of  FIG. 8F , “picture 20” is the editable item. 
       FIG. 9A  is a view showing a format of the editable item,  FIG. 9B  is a view showing the editable item with respect to the display of DS  201  defined with the format of  FIG. 9A ,  FIG. 9C  is a view showing the editable item with respect to the display of DS  202  defined with the format of  FIG. 9A ,  FIG. 9D  is a view showing the editable item with respect to the display of DS  203  defined with the format of FIG.  9 A, and  FIG. 9E  is a view showing the editable item with respect to the display of DS  204  defined with the format of  FIG. 9A . The format of the editable item of  FIG. 9A  is defined by the description “playback log”, which indicates that the playback log is received and the editable item is determined, and the “content name”, the “screen name”, and the “editing area name” indicating the editable items. A plurality of descriptions can be made in the “editing area name”. Here, each of the “content name”, the “screen name”, and the “editing area name” corresponds to the “content name”, the “screen name definition”, and the “constituent definition” of signage data format  301 . The editable item of  FIG. 9B  is the editable item with respect to the display of DS  201 , and “Manpuku Diner”, “Pork Cutlet Set Meal”, and “picture 10” are described after the description of the “playback log”. The editable item of  FIG. 9C  is the editable item with respect to the display of DS  202 , and “Manpuku Diner”, “Pork Cutlet Set Meal”, and “text 11” are described after the description of the “playback log”. The editable item of  FIG. 9D  is the editable item with respect to the display of DS  203 , and “Manpuku Diner”, “Pork Cutlet Set Meal”, “text 12”, and “12:00:06” are described after the description of the “playback log”. The editable item of  FIG. 9E  is the editable item with respect to the display of DS  204 , and “Manpuku Diner”, “Fried Calamari Set Meal”, and “picture 20” are described after the description of the “playback log”. 
     Note that the editable item may be determined so as to synchronize with signage data  302  displayed on signage display device  103 . Specifically, the difference between the playback time (T1) included in the playback log and the current time (T2) is calculated (T3), the signage data displayed at the time obtained by adding the difference (T3) to the playback time (T1) is specified, and the editable item is determined. For example, when the current time at which the playback log of  FIG. 8C  is received is “12:00:03”, T3 is three seconds since the playback time of the playback log of  FIG. 8C  is “12:00:00”. DS  202  is played at the time of “12:00:03”, and hence the editable item with respect to the display of DS  202  is the editable item of  FIG. 9C . 
     The current time may be determined from the clock function held by signage server  102 , or may be acquired from the NTP (Network time protocol) server, for example.

     [1-4. Configuration of Signage Data Input Device] 
       FIG. 12  is a function block diagram of signage data input device  101 .  FIG. 13  is a flowchart showing the operation of signage data input device  101 . 
     Signage data input device  101  is configured by item receiving unit  1201 , editing unit  1202 , picture DB  1203 , photographing unit  1204 , and change transmitting unit  1205 . 
     Item receiving unit  1201 , editing unit  1202 , and change transmitting unit  1205  are realized, for example, by a wireless or wired communication device, and a processor that executes a predetermined process. Such functions may be realized by one processor, or may be assigned and realized by a plurality of processors. Picture DB  1203  is realized, for example, by an optically-readable or magnetically-readable recording medium. Photographing unit  1204  is, for example, realized by an imaging device including an optical system such as a focus lens, and an image sensor. 
     Item receiving unit  1201  receives the editable item or the update-content information transmitted from signage server  102 , and transmits the same to editing unit  1202 . The operation described in  FIG. 13  is continued while the editable item or the update-content information transmitted from signage server  102  is received. 
     (S 1301 ) Editing unit  1202  determines whether the data received from item receiving unit  1201  is the editable item or the update-content information. The process proceeds to S 1302  when the editable item is received, and proceeds to S 1303  when the update-content information is received. 
     (S 1302 ) Editing unit  1202  displays the edit screen with respect to the editable item. For example, when the editable item is the case of  FIG. 9D , the edit screen displays ED  203 . ED  203  is an edit screen for editing price  213  of “735 yen”, and includes a region for inputting text and an “edit” button for starting the editing. When the editable item is the case of  FIG. 9B , the edit screen displays ED  201 . ED  201  is provided for editing the picture, and includes an “edit” button for starting the editing, a “select” button for using the picture data accumulated in picture DB  1203 , and a “camera” button for using the picture data photographed by photographing unit  1204 .

For example, when the update-content information is the case of  FIG. 9G , the edit screen displays ED  503 . ED  503  is an edit screen that shows that price  213  of “735 yen” is edited and updated to price  213 A of “630 yen”, and further enables editing of price  213 A of “630 yen”, and includes a region for inputting text and an “edit” button for starting editing. 
     (S 1304 ) Editing unit  1202  determines whether or not the user pressed the “edit” button while an arbitrary edit screen is being displayed. When the “edit” button is pressed (if Yes), the process proceeds to S 1305 , and when the “edit” button is not pressed (if No), the process returns to S 1301 . 
     (S 1305 ) When the editable item is text, the user edits the text of the region for inputting the text when editing. When the editable item is a picture, the user presses the “picture” button and selects the picture data to use from the picture data recorded in picture DB  1203  when the picture data recorded in picture DB  1203  is used for editing. When the picture data photographed by using the camera function is used for editing, the user presses the “camera” button. Photographing unit  1204  has a camera function, and may record the photographed picture data in picture DB  1203 . The user presses the “confirm” button of the edit screen when the editing is terminated, and presses the “return” button of the edit screen to cancel the editing. As an example of editing, for example, the display screen is switched to ED  203 A when the “edit” button of ED  203  is pressed. The user edits the text in the region for inputting the text of ED  203 A, and presses the “confirm” button to confirm editing and presses the “return” button to cancel editing. In ED  203 A, “735 yen” is edited to “630 yen”. 
     Editing unit  1202  determines whether or not the “confirm” button or the “return” button of the edit screen is pressed. When it is determined that the “confirm” button is pressed, the process proceeds to S 1306 , and when it is determined that the “return” button is pressed, the process returns to S 1301 . 
     (S 1306 ) Editing unit  1202  transmits the edit-content information to change transmitting unit  1205 . Change transmitting unit  1205  transmits the edit-content information received from editing unit  1202  to signage server  102 . The edit instruction of  FIG. 11B  is transmitted to signage server  102  with respect to the edit-content information of the edit screen of ED  203 A. 
     [1-5. Configuration of Signage Display Device]

     (S 1501 ) Data receiving unit  1401  receives the instruction to start the display of the signage data from signage server  102 . 
     (S 1502 ) When the edit instruction of signage data  302  is received from signage server  102 , data receiving unit  1401  transmits the edit instruction to updating unit  1402  (if Yes) and proceeds to S 1503 . When the edit instruction is not received (if No), data receiving unit  140  proceeds to S 1504 . 
     (S 1503 ) When the edit instruction is received, updating unit  1402  edits and updates corresponding signage data  302  recorded in signage data DB  1403 . 
     (S 1504 ) When signage data  302  is received at the same time as the instruction to start the display of the signage data, updating unit  1402  transmits signage data  302  to updating unit  1402 , and records signage data  302  in signage data DB  1403 . When signage data  302  is received separately from the instruction to start the display of the signage data, data receiving unit  1401  receives the signage data transmitted from signage server  102 , transmits the same to updating unit  1402 , and records signage data  302  in signage data DB  1403 . 
     Updating unit  1402  transmits the instruction to start the display to display unit  1404 . Display unit  1404  starts to display signage data  302  recorded in signage data DB  1403  when the instruction to start the display is received, and continuously displays the data if the instruction to start the display is already received. The update-content information is displayed when the edit instruction is given. As an example of the display, for example, display is made in the order of DS  201 , DS  202 , DS  203 , DS  204 , DS  205 , and DS  206  as in the example of  FIG. 2 . As an example of the display when the edit instruction is given, for example, display is made as in DS  203 A of  FIG. 5 . 
     (S 1505 ) Log generating unit  1405  generates the playback log or the update log to transmit to signage server  102  in correspondence with the display of display unit  1404 , and transmits the same to log transmitting unit  1406 . The logs shown in  FIG. 8C ,  FIG. 8D ,  FIG. 8E , and  FIG. 8F  are generated as an example of the playback log, and the log shown in  FIG. 8G  is generated as an example of the update log. 
     (S 1506 ) Log transmitting unit  1406  transmits the playback log or the update log to signage server  102 . 
     (S 1507 ) When the instruction to end the display of the signage data is received from signage server  102  (if Yes), data receiving unit  1401  terminates the process, and when the instruction to end the display of the signage data is not received (if No), data receiving unit  1401  returns to S 1502  and continues the process. 
     [1-3. Effect] 
     As described above, the signage data input device of the present disclosure is a signage data input device that performs editing in conjunction with the signage data displayed on the signage display device, and includes an item receiving unit configured to receive an editable item in conjunction with the signage data displayed on the signage display device, an editing unit configured to display an edit screen for editing the editable item and accepts edit-content information, and a change transmitting unit configured to transmit the edit-content information as the edit instruction. The server of the present disclosure is a server that controls the display of the signage data of the signage display device and the editing of the signage data displayed on the signage display device of the signage data input device, and includes a log receiving unit configured to receive the display result of the signage data displayed on the signage display device as a log, an analyzing unit configured to extract the editable item from the log, an item transmitting unit configured to transmit the editable item to the signage data input device, an edit instruction receiving unit configured to receive the edit instruction with respect to the signage data displayed on the signage display device from the signage data input device, an updating unit configured to edit the signage data displayed on the signage display device based on the edit instruction, and a data transmitting unit configured to transmit the edit instruction to the signage display device. 
     Thus, the edit screen is displayed in conjunction with the display-content information of the signage display device, so that the display-content information can be easily changed. 
     In the data input device of the present disclosure, the editable item includes the update time when the signage data displayed on the signage display device is the edited signage data, and the editing unit displays the update time when the edit screen is displayed. 
     Thus, the change in the displayed content information of the signage display device can be known with the signage data input device. 
     In the data input device of the present disclosure, the editable item received by the item receiving unit includes the time displayed on the signage display device, and the editing unit calculates the difference between the current time and the time of the editable item to specify the editable item to be displayed on the edit screen. 
     Thus, the editable item can be determined so as to be synchronized with the signage data displayed on the signage display device. 
     In the server of the present disclosure, when the edit instruction receiving unit receives that editing is being carried out on the signage data displayed on the signage display device from the signage data input device, the updating unit controls the data transmitting unit so as to temporarily stop the display of the signage data being displayed on the signage display device. 
     Thus, the edit screen of the signage data input device and the display-content information of the signage display device become the same display-content information, and thus the editing can be carried out while viewing the display-content information of the signage display device and the display-content information of the display device can be more easily changed. 
     Other Exemplary Embodiments 
     The data input system of the present disclosure has been described above in the exemplary embodiment. A variant of the exemplary embodiment described above will be described below. 
     [2-1. Display of Update-Content Information] 
     One example in which editing is performed in signage data input device  101  has been described with reference to  FIG. 5 , but a different display may be carried out.  FIG. 16  is a view showing another example in which editing is performed by using the edit screen of signage data input device  101 . As described in  FIG. 5 , the user presses the “edit” button of ED  203  to update price  213  of “735 yen”. When the “edit” button is pressed, the display screen is switched to ED  203 A. In ED  203 A, “735 yen” is edited to “630 yen”. When the “confirm” button is pressed in ED  203 A, signage data input device  101  transmits the edited content information to signage server  102 , and signage server  102  notifies the edited content information to signage display device  103 . 
     Signage display device  103  that received the notification displays DS  203 A, which is the update screen of DS  203 . Price  213  of “735 yen” is updated to price  213 A of “630 yen”. Signage display device  103  transmits the playback log indicating that update has been carried out to signage server  102 , and signage sever  102  transmits the update-content information and the update time to signage data input device  101 . 
     Signage data input device  101  displays ED  1601  of  FIG. 16 , which is the edit screen presenting the update-content information and the update time. ED  1601  displays DS  203 A displayed on signage display device  103  as is on the screen. According to such display, the update result can be checked on signage data input device  101  without actually viewing the display result of signage display device  103 . When the “edit” button is pressed in ED  1601 , the updating area can be edited again. 
     [2-2. Display of Edit Screen] 
     In the exemplary embodiment described above, the signage data is edited using signage data input device  101  in conjunction with the signage data displayed on signage display device  103 , but the present disclosure is not limited thereto. 
       FIG. 17  is a view showing still another example in which editing is performed using the edit screen of signage data input device  101 . 
     Signage data input device  101  does not display the edit screen in conjunction with the display of the signage data of signage display device  103 , but directly decodes signage data  302  recorded in signage data DB  607  of signage server  102  and displays the same on the edit screen independently from signage display device  103 . Specifically, the editable items defined in signage data  302  are switched in order from the beginning. For example, the editable items are switched in the order of ED  1701 , ED  1702 , ED  1703 . ED  1701  is an edit screen for editing picture  211  of “Pork Cutlet Set Meal”. ED  1702  is an edit screen for editing menu name  212  of “Pork Cutlet Set Meal”. ED  1703  is an edit screen for editing price  213  of “735 yen”. ED  201 , ED  202 , and ED  203  described in  FIG. 4  differ in that the “next” button is provided. In switching, the switching may be carried out based on the display time defined in signage data  302  or the switching may be carried out by pressing the “next” button. 
     The display of signage display device  103  may be switched in conjunction with the display of the edit screen of signage data input device  101 . Specifically, DS  1701  is displayed while ED  1701  is being displayed on signage data input device  101 , DS  1702  is displayed when the display of the edit screen is switched to ED  1702 , and DS  1703  is displayed when the display of the edit screen is switched to ED  1703 . In this case, the playback log is transmitted from signage data input device  101  to signage server  102 , and the playback log received by signage server  102  is transmitted to signage display device  103 , so that the switching of the screen can be cooperatively carried out. 
     [2-3. When Plurality of Editable Items are Present]
