When the operator instructs to start the slide show display using the operation unit 102, the display terminal device 100 expands the display data stored in the data storage unit 105 (see FIG. 2 described later) using the display application. The display unit 101 can display a plurality of display data in a slide show format.

  The display unit 101 and the operation unit 102 constitute a display unit and an operation unit described in the claims.

  Next, the functional configuration of the entire system of the slide show display system 1 will be described with reference to FIG.

  In FIG. 2, the display terminal device 100 is a network between the display unit 101 for displaying various display data, the operation unit 102 that allows the operator to instruct the start of slide show display, and the server 200. The network communication control unit 103 that controls network communication performed via the NW, and the control circuit 104 that controls the operation of the entire display terminal device 100 including the display unit 101 and the network communication control unit 103 are included.

  The control circuit 104 is a so-called microcomputer, and although not shown in detail, is constituted by a central processing unit such as a CPU, a ROM, and a RAM. The control circuit 104 uses a temporary storage function of the RAM and stores a program stored in advance in the ROM, for example, a display processing program that causes a CPU as a calculation unit to execute a data display method shown in FIGS. Perform signal processing.

  In addition, the display terminal device 100 includes a data storage unit 105, a table storage unit 106, and an application storage unit 107. These storage units 105, 106, and 107 are composed of, for example, a hard disk or a large-capacity memory, and the control circuit 104 can read / write information from / to these storage units 105, 106, and 107. The data storage unit 105 stores a plurality of display data for performing a slide show display. Various tables are stored in the table storage unit 106. The table stored in the table storage unit 106 displays the data ID of the display data to be displayed in the slide show among the plurality of display data stored in the data storage unit 105 and the display of display data corresponding to each data ID. A display control information table (see FIG. 10 described later) including the order is included. In the present embodiment, the display time of each display data is fixedly set to be a predetermined common time. The display control information table corresponds to the display control information described in the claims.

  The application storage unit 107 stores a plurality of display applications for expanding display data in a predetermined data format so that the display data can be displayed. The control circuit 104 sequentially reads display data from the data storage unit 105 according to the display order set in the display control information table, and executes a slide show display using the display application stored in the application storage unit 107.

  The server 200 includes a network communication control unit 201 that controls network communication performed with the display terminal device 100 via the network NW, and a control circuit 202 that controls the entire server 200. The server 200 also has a table storage unit 203 and an application storage unit 204. The application storage unit 204 stores a plurality of display applications for expanding display data in a predetermined data format so that it can be displayed. The display application includes, for example, an application distributed free of charge on the Internet, an application purchased as many licenses as necessary if necessary, and the like.

  The table storage unit 203 includes a display application list information table including application IDs of all display applications stored in the application storage unit 204, extensions corresponding to the application IDs, application presence / absence flags, and acquisition times. (See FIG. 8 to be described later). This display application list information table is for the operator to manage whether or not the display terminal device 100 has a display application for displaying which extension is held and the time for acquisition. When the operator accesses the display terminal device 100 before executing the slide show, the “app presence / absence flag” and the “acquisition time” are calculated from the information on the server 200 and the display terminal device 100 and the communication line information. Data of this display application list information table is created. Note that the display application list information table may be stored in the table storage unit 106 of the display terminal device 100. The application presence / absence flag is a flag for identifying which of the display applications stored in the application storage unit 204 is stored in the application storage unit 107 of the display terminal device 100. The acquisition time is necessary for the display circuit 100 to develop the display data when a plurality of display data includes display data that cannot be developed by the display application stored in the application storage unit 107. This is the time required to acquire the display application from the server 200 via the network NW. This acquisition time is determined based on the data size of each display application and the data communication speed between the display terminal device 100 and the server 200, but depending on the communication environment between the display terminal device 100 and the server 200, etc. You may make it determine by calculating.

  The data storage unit 105, the table storage unit 106, and the application storage unit 107 constitute a data storage unit, a control information storage unit, and an application storage unit described in the claims. Further, the data ID of the display data corresponds to the identification information described in the claims. Further, the extension corresponds to the identifier described in the claims.

  In the slide show display system 1 configured as described above, when performing a slide show display, the control circuit 104 of the display terminal device 100 first acquires the display application list information table from the table storage unit 203 of the server 200. Next, based on the extension corresponding to each application ID included in the application list information table and the respective extensions of the plurality of display data including the data ID in the display control information table, the application is applied to the plurality of display data. It is determined whether display data that cannot be expanded other than display data that can be expanded using the display application stored in the storage unit 107 is included. When display data that cannot be expanded is included in the plurality of display data, a display application necessary for expansion of the display data is acquired from the server 200 via the network NW. At this time, the control circuit 104 determines the display order of the plurality of display data in the display control information table based on the acquisition time of the display application to be acquired. In this way, it is possible to acquire a display application for display data that cannot be expanded on the display terminal device 100 while a slide show using display data that can be expanded on the display terminal device 100 is being executed. Yes. Hereinafter, this detailed content is demonstrated. In the following description, display data that cannot be expanded by the display terminal device 100 will be referred to as “undeployable data”, and display data that can be expanded by the display terminal device 100 will be referred to as “expandable data”.

  Next, the control content executed by the control circuit 104 of the display terminal apparatus 100 will be described with reference to FIG.

  First, in step S <b> 10, the control circuit 104 determines whether or not a slide show display execution start instruction has been made based on an input signal from the operation unit 102. This determination is repeated until a start instruction is given. If a start instruction is given, the determination is satisfied and the routine goes to Step S100.

  Next, in step S <b> 100, the control circuit 104 executes display application list acquisition processing for acquiring a display application list information table from the server 200. Details of the display application list acquisition process will be described later.

  In step S200, the control circuit 104 executes a display control information setting process for setting a display control information table that defines the display order of display data. Details of the display control information setting process will be described later.

  Next, the control circuit 104 executes the data display process in step S300 and the display application acquisition process in step S400 simultaneously in parallel. The data display process is a process of displaying a plurality of display data according to the display control information table set by the display control information setting process. The display application acquisition process is a process of acquiring a display application necessary for developing display data from the server 200. Such concurrent processing can be performed by one CPU by a known method similar to “multitask processing” often performed by, for example, an OS of a computer. Details of these data display processing and display application acquisition processing will be described later.

  Thereafter, in step S20, after completing the slide show display of the display data according to the display control information table, the control circuit 104 acquires the display application acquired from the server 200 and stored in the application storage unit 107 in the display application acquisition process. Delete from the application storage unit 107. And this flowchart is complete | finished.

  The step 20 functions as an application deletion unit described in the claims. Step 300 and step S400 correspond to the data display / application acquisition procedure described in the claims.

  Next, details of the display application list acquisition process in step S100 will be described with reference to FIG.

  First, in step S110, the control circuit 104 accesses the server 200 via the network NW based on the communication control of the network communication control unit 103.

  Next, in step S <b> 120, the control circuit 104 acquires a display application list information table from the table storage unit 203 of the server 200. As described above, in this display application list information table, the application IDs of all display applications stored in the application storage unit 204 are associated with extensions corresponding to the application IDs, application presence / absence flags, and acquisition times. ing.

  In step S <b> 130, the control circuit 104 stores the acquired display application list information table in the table storage unit 106. Then, this subroutine ends.

  Next, the detailed contents of the display control information setting process in step S200 will be described with reference to FIG.

  First, in step S <b> 205, the control circuit 104 reads one piece of data from the data table stored in the table storage unit 106. This one piece of data is data corresponding to one record on the table. Hereinafter, in the description of the flowchart in FIG. 5, one piece of data read here is appropriately referred to as “data A” in order to distinguish it from data read from a pending data table described later. The data table associates data IDs of a plurality of display data stored in the data storage unit 105 with data names, extensions, and other data corresponding to each data ID, and follows a predetermined initial order. These are arranged (see FIG. 9 described later) and are stored in the table storage unit 106 in advance.

  The data table corresponds to the initial control information described in the claims, and the table storage unit 106 in which the data table is stored constitutes an initial information storage unit.

  In step S <b> 210, the control circuit 104 determines whether or not a display application for expanding the display data corresponding to the read data A is displayed in the application storage unit 107. This determination is made by referring to the display application list information table acquired from the server 200 in step S100 and stored in the table storage unit 106, and the presence / absence of an application corresponding to the application ID having the same extension as that included in the data A This is done by referring to the flag. If the display application corresponding to the data A exists in the application storage unit 107, the determination is satisfied, and the routine goes to Step S215.

  In step S215, the control circuit 104 adds the data ID corresponding to the data A together with the display time to the display control information table stored in the table storage unit 106. As described above, this display time is fixedly set to be a common time for each display data. Thereafter, the process proceeds to step S245 described later.

  On the other hand, if the display application corresponding to the data A does not exist in the application storage unit 107 in step S210, the determination is not satisfied and the process proceeds to step S220.

  In step S220, the control circuit 104 determines whether or not the acquisition time required for acquiring the display application necessary for expanding the display data corresponding to the data A is equal to or less than a predetermined threshold value. This determination is performed by referring to the display application list information table acquired from the server 200 in step S100 and stored in the table storage unit 106, and the acquisition time corresponding to the application ID having the same extension as that included in the data A. And the threshold value. If the acquisition time is larger than the threshold, it is assumed that the acquisition time of the display application is excessively long and the acquisition cannot be performed during the execution of the slide show, and the determination is not satisfied, and the process proceeds to step S285 described later. On the other hand, if the acquisition time is less than or equal to the threshold, the determination is satisfied and the routine goes to Step S225.

  In step S <b> 225, the control circuit 104 determines whether a display application necessary for expanding display data corresponding to the data A conforms to the specifications of the display terminal device 100. When the corresponding display application does not conform to the specifications of the display terminal device 100, the display data does not correspond to the display application 100, and the display data corresponding to the data A is displayed during the slide show. Since it cannot be expanded, the determination is not satisfied, and the routine goes to Step S285 described later. On the other hand, if the corresponding display application conforms to the specifications of the display terminal device 100, the determination is satisfied and the routine goes to Step S230.

  In step S <b> 230, the control circuit 104 determines whether or not a display application necessary for developing display data corresponding to the data A is registered in the display application acquisition order table stored in the table storage unit 106. The display application acquisition order table defines the types of display applications acquired in the display application acquisition process in step S400 described above and the acquisition order (see FIG. 12 described later), and is stored in the table storage unit 203. Yes. If the corresponding display application is registered in the display application acquisition order table, the determination is satisfied, and the routine goes to Step S240 described later. On the other hand, if the corresponding display application is not registered in the display application acquisition order table, the determination is not satisfied and the routine goes to Step S235.

  In step S235, the control circuit 104 adds the extension and application ID of the display application corresponding to the data A to the display application acquisition order table stored in the table storage unit 106.

  In step S240, the control circuit 104 adds the data ID corresponding to the data A together with the display time to the pending data table stored in the table storage unit 106. The hold data table is for holding data A until it is added to the display control information table in step S215 described above (see FIG. 11 described later), and is stored in the table storage unit 203. ing. Thereafter, the process proceeds to step S245.

  In step S245, the control circuit 104 refers to the pending data table stored in the table storage unit 106, and determines whether data exists in the pending data table. If there is no data in the pending data table, the determination is not satisfied and the routine goes to Step S285 described later. On the other hand, if there is data in the pending data table, the determination is satisfied, and the routine goes to Step S250.

  In step S250, the control circuit 104 reads one piece of data from the pending data table stored in the table storage unit 203. This one piece of data is data corresponding to one record on the table. Hereinafter, in the description of the flowchart in FIG. 5, in order to distinguish from the data A read from the data table, one piece of data read here is appropriately referred to as “data B”.

  In step S255, the control circuit 104 refers to the display control information table stored in the table storage unit 106, and calculates the total display time of data registered in the display control information table. Hereinafter, in the description of the flowchart in FIG. 5, the calculated total time is appropriately referred to as “time A”.

  In step S260, the control circuit 104 refers to the display application list information table acquired from the server 200 in step S100 and stored in the table storage unit 106, and expands the display data corresponding to the read data B so as to be displayed. The acquisition time for acquiring the display application for acquiring from the server 200 is acquired. Hereinafter, in the description of the flowchart in FIG. 5, the acquired acquisition time is appropriately referred to as “time B”. As described above, this acquisition time may be calculated and determined as needed according to the communication environment between the display terminal device 100 and the server 200.

  In step S265, the control circuit 104 determines whether or not the time A calculated in step S255 is equal to or longer than the time B acquired in step S260. When the time A is less than the time B, the display application for unexpandable data that cannot be displayed on the display terminal device 100 is acquired during the execution of the slide show using the expandable data that can be displayed on the display terminal device 100. It is considered that it cannot be performed, and the determination is not satisfied, and the routine goes to Step S280 described later. On the other hand, when the time A is equal to or longer than the time B, it is assumed that it is possible to acquire a display application for unexpandable data during execution of a slide show using expandable data, and the determination is satisfied. The process moves to step S270.

  In step S270, the control circuit 104 adds the data ID corresponding to the data B together with the display time to the display control information table stored in the table storage unit 106.

  In step S275, the control circuit 104 deletes the data ID corresponding to the data B and the display time from the pending data table.

  In step S280, the control circuit 104 refers to the pending data table stored in the table storage unit 106 and determines whether or not unprocessed data exists in the pending data table. If unprocessed data exists, the determination is satisfied and the routine returns to the previous step S250. On the other hand, if there is no unprocessed data, the determination is not satisfied and the routine goes to the next step S285.

  In step S285, the control circuit 104 refers to the data table stored in the table storage unit 106, and determines whether or not unprocessed data exists in the data table. If unprocessed data exists, the determination is satisfied and the routine returns to the previous step S205. On the other hand, if there is no unprocessed data, the determination is not satisfied and this subroutine is terminated.

  In the display control information setting process, all the data included in the data table is processed in steps S205 to S285, so that in step S210, a plurality of display data stored in the data storage unit 105 is included. It is determined whether or not unexpandable data other than expandable data that can be expanded using the display application stored in the application storage unit 107 is included. Therefore, step S210 functions as a data determination unit described in the claims and corresponds to a data determination procedure. Step S260 functions as an acquisition time determination unit and corresponds to an acquisition time determination procedure.

  Furthermore, when it is determined in step S210 that the plurality of display data includes unexpandable data, in step S270, the data ID is added to the display control information table based on the display application acquisition time, and the display control information table The display order of the plurality of display data in is determined. Therefore, step S210 functions as a display determination unit described in the claims and corresponds to a display determination procedure. When the total display time of the data registered in the display control information table in step S265 is equal to or longer than the acquisition time for acquiring the corresponding display application from the server 200, the display order is determined in step S270. Therefore, in step S270, display of a plurality of display data in the display control information table is completed so that acquisition of a display application necessary for expansion of unexpandable data is completed while expandable data is displayed on the display unit 101. The order will be determined.

  Further, step S205 functions as a reading unit described in the claims, and step S220 functions as an acquisition time determination unit. Further, this step S220 has a function of excluding registration of the data ID related to the unexpandable data in the display control information table in the subsequent step S270 when it is determined that the acquisition time is larger than the threshold value. Therefore, it also functions as first exclusion processing means described in the claims.

  Further, step S225 functions as a conformity determination unit described in the claims. In step S225, when it is determined that the display application necessary for developing the unexpandable data does not conform to the specifications of the display terminal device 100, the data ID related to the unexpandable data is displayed in the display control information in the subsequent step S270. Since it also functions to exclude being registered in the table, it also functions as second exclusion processing means described in the claims.

  Further, step S275 functions as an application deletion unit described in the claims.

  Next, the details of the data display process in step S300 will be described with reference to FIG.

  First, in step S <b> 310, the control circuit 104 reads one piece of data from the display control information table stored in the table storage unit 106. This one data is data corresponding to one record on the table. In this case, the data ID and the display time are included.

  Next, in step S320, the control circuit 104 reads display data corresponding to the one read data from the data storage unit 105, and also reads a display application corresponding to the display data from the application storage unit 107, and displays the display data. Display data is developed using an application and displayed on the display unit 101.

  Next, in step S330, the control circuit 104 determines whether or not the elapsed time from the start of display of the display data has reached the display time included in the one read data. This determination is repeated until the elapsed time reaches the display time. When the elapsed time reaches the display time, the determination is satisfied, and the routine goes to Step S340.

  In step S340, the control circuit 104 refers to the display control information table stored in the table storage unit 106, and determines whether the data next to the data read in step S310 exists on the display control information table. To do. If the next data exists, the determination is satisfied and the routine returns to the previous step S310. On the other hand, if the next data does not exist, the determination is not satisfied and this subroutine is terminated.

  With the above control, the control circuit 104 sequentially reads display data from the data storage unit 105 in accordance with the display order set in the display control information table, and executes a slide show display using the display application stored in the application storage unit 107. .

  In the above, step S320 functions as a data expansion means described in the claims.

  Next, the details of the display application acquisition process in step S400 will be described with reference to FIG.

  First, in step S <b> 410, the control circuit 104 reads one piece of data from the display application acquisition order table stored in the table storage unit 106. This one piece of data is data corresponding to one record on the table, and in this case, an extension and an application ID are included.

  Next, in step S420, the control circuit 104 accesses the server 200 via the network NW based on the communication control of the network communication control unit 103, and from the application storage unit 204, the application included in the read one piece of data. A display application corresponding to the ID is acquired and stored in the application storage unit 107.

  Next, in step S430, the control circuit 104 refers to the display application acquisition order table stored in the table storage unit 106, and whether the next data after the data read in step S410 exists on the display application acquisition order table. Determine whether or not. If the next data exists, the determination is satisfied and the routine returns to the previous step S410. On the other hand, if the next data does not exist, the determination is not satisfied and this subroutine is terminated.

  In the display application acquisition process in step S400, in the display control information setting process in step S200 described above, if the determination in step S210 is not satisfied and data is registered in the display application acquisition order table in step S235, in other words For example, if it is determined in step S210 that display data that cannot be expanded is included in the plurality of display data, the display application is acquired. If the data is not registered in the display application acquisition order table, the display application Acquisition is not performed. Therefore, the display application acquisition process in step S400 described above functions as an application acquisition unit described in the claims.

  Next, the control content described above will be described using the specific examples shown in FIGS. Note that the display control information table and the display application acquisition order table shown in FIGS. 10 and 12 represent the state at the time when the display control information setting process in step S200 is completed, and the pending data table shown in FIG. All data registered in the table during the display control information setting process in step S200 is shown for explanation. Therefore, at the start of the display control information setting process in step S200, none of the tables shown in FIGS. 10 to 12 are registered. On the other hand, the display application list information table and the data table shown in FIGS. 8 and 9 are registered in advance in the state shown in the figure.

  In the display terminal device 100, when the operator gives an instruction to start slide show display, the determination in step S10 shown in FIG. 3 is satisfied, and the process proceeds to step S100. In the display application list acquisition process shown in FIG. Is displayed from the server 200 and stored in the table storage unit 106 of the display terminal device 100.

  Next, the display control information setting process in step S200 shown in FIG. 5 is executed. First, in step S205, data relating to the data ID “DATA0001”, which is the first record in the data table shown in FIG. 9, is read, and in the next step S210, display data corresponding to the read data can be displayed. It is determined whether or not a display application to be expanded in the application storage unit 107 exists. Here, the extension corresponding to the data ID “DATA0001” is “jpg”, and referring to the display application list information table shown in FIG. 8, the application presence / absence flag corresponding to the application ID “AP0001” of the extension “jpg” is shown. Is “present”, the display application exists in the application storage unit 107 of the display terminal device 100. Therefore, the determination in step S210 is satisfied and the process proceeds to step S215.

  In step S215, the data ID “DATA0001” corresponding to the read data is added together with the display time to the first display order in the display control information table shown in FIG. Note that, as described above, FIG. 10 shows the display control information table in a state where the display control information setting process has been completed for all data in the data table. At this time, the display control information table relates to the first data ID “DATA0001” in the display order. Only the record part is registered. In the example shown in the figure, the display time of each display data is set to “3” seconds.

  In the next step S245, it is determined whether or not there is data in the hold data table. At this time, since no data is registered in the hold data table, the determination is not satisfied and the process proceeds to step S285. In step S285, it is determined whether or not unprocessed data exists in the data table. At this point, data other than the data related to the data ID “DATA0001” is unprocessed, and therefore the determination is satisfied and the process returns to step S205. Return.

  In this step S205, data relating to the data ID “DATA0002”, which is the second record in the data table shown in FIG. 9, is read, and in the next step S210, a display application corresponding to the read data is displayed on the display terminal. It is determined whether or not the device 100 exists. Here, since the extension corresponding to the data ID “DATA0002” is “jpg” as described above, and the display application exists in the application storage unit 107 of the display terminal device 100, the determination in step S210 is satisfied. Then, the process proceeds to step S215.

  In step S215, the data ID “DATA0002” corresponding to the read data is added along with the display time to the second display order in the display control information table shown in FIG. As a result, two records associated with the data IDs “DATA0001” and “DATA0002” are registered in the display control information table. At this time, since no data is registered in the pending data table, the determination in the next step S245 is not satisfied and the process proceeds to step S285, and there is unprocessed data in the data table, so the determination in step S285 is satisfied. Then, the process returns to step S205 again.

  In this step S205, data relating to the data ID “DATA0003”, which is the third record in the data table shown in FIG. 9, is read, and in the next step S210, a display application corresponding to the read data is displayed on the display terminal. It is determined whether or not the device 100 exists. Here, the extension corresponding to the data ID “DATA0003” is “gif”, and referring to the display application list information table shown in FIG. 8, the application presence / absence flag corresponding to the application ID “AP0004” of the extension “gif” is shown. Is “None”, the display application does not exist in the application storage unit 107 of the display terminal device 100. Therefore, the determination at step S210 is not satisfied, and the routine goes to step S220.

  In step S220, it is determined whether or not the acquisition time required to acquire the display application corresponding to the read data is equal to or less than a predetermined threshold value. Here, it is assumed that the acquisition time of the application ID “AP0004” is “14” seconds from the display application list information table shown in FIG. Therefore, the determination is satisfied and the routine goes to Step S225. In step S225, it is determined whether or not the display application corresponding to the read data conforms to the specifications of the display terminal device 100. Here, it is assumed that the display application corresponding to the application ID “AP0004” conforms to the specification of the display terminal device 100. Therefore, the determination is satisfied and the routine goes to Step S230.

  In step S230, it is determined whether or not a display application corresponding to the application ID “AP0004” is registered in the display application acquisition order table. At this time, since the data is not yet registered in the display application acquisition order table, the determination is not satisfied, and the routine goes to Step S235. In step S235, the extension “gif” and the application ID “AP0004” of the corresponding display application are added to the display application acquisition order table. Note that, as described above, FIG. 12 shows the display application acquisition order table in a state where the display control information setting process has been completed. At this time, only the record portion related to the application ID “AP0004” is registered. ing.

  In the next step S240, the corresponding data ID “DATA0003” is added to the pending data table together with the display time “3” seconds. Note that, as described above, FIG. 11 shows the pending data table in which all data registered during the display control information setting process in step S200 is registered, but at this time, the record associated with the data ID “DATA0003” Only the part is registered.

  In the next step S245, since the data is registered in the pending data table in the above step S240, the determination is satisfied, and the routine goes to step S250. In this step S250, one piece of data from the hold data table, that is, the data of the record portion related to the data ID “DATA0003” registered in the above step S240 is read.

  In the next step S255, the total display time of the data registered in the display control information table is calculated. At this time, since the two records related to the data IDs “DATA0001” and “DATA0002” are registered in the display control information table as described above, the total display time is “3 + 3 = 6” seconds. It becomes. In the next step S260, an acquisition time for acquiring a corresponding display application from the server 200 with reference to the display application list information table is acquired. Here, the acquisition time “14” seconds of the display application corresponding to the application ID “AP0004” is acquired.

  In the next step S265, it is determined whether or not the total display time “3 + 3 = 6” seconds is equal to or longer than the display application acquisition time “14” seconds. Here, since the determination is not satisfied, the process proceeds to step S280. At this time, since data other than the data ID “DATA0003” is not registered in the pending data table, the determination in step S280 is not satisfied and the process proceeds to step S285, and there is unprocessed data in the data table. Is satisfied and the process returns to step S205 again.

  In this step S205, data relating to the data ID “DATA0004” which is the fourth record in the data table shown in FIG. 9 is read, and in the next step S210, a display application corresponding to the read data is displayed on the display terminal. It is determined whether or not the device 100 exists. Here, since the extension corresponding to the data ID “DATA0004” is “gif” as described above, and the display application does not exist in the application storage unit 107 of the display terminal device 100, the determination in step S210 is not satisfied. To step S220.

  As described above, the determinations in step S220 and step S225 are satisfied, and the routine goes to step S230. At this time, since the display application corresponding to the extension “gif” and the application ID “AP0004” is registered in the display application acquisition order table, the determination is satisfied, and the routine goes to Step S240. In this step S240, the corresponding data ID “DATA0004” is added to the pending data table together with the display time “3” seconds. As a result, two records relating to the data IDs “DATA0003” and “DATA0004” are registered in the pending data table.

  Since there is data in the pending data table at this time, the determination in the next step S245 is satisfied and the process proceeds to step S250, where one data from the pending data table, that is, the data ID “ Data related to “DATA0003” is read. Since the registration contents of the display control information table are not changed from the above, the total display time of the registration data is “3 + 3 = 6” seconds. Since the total time is not longer than the acquisition time “14” seconds of the display application corresponding to the application ID “AP0004”, the determination in step S265 is not satisfied, and the process proceeds to step S280.

  In step S280, since there is data related to the unprocessed data ID “DATA0004” in the pending data table, the determination is satisfied and the routine returns to step S250. As a result, in step S250, the next data item, that is, the data related to the data ID “DATA0004”, which is the second-stage record portion, is read from the pending data table. Then, the processing from step 255 is executed again on the data associated with the data ID “DATA0004”. Since the acquisition time of the corresponding display application is the same, the same result as described above is obtained, and the process again proceeds to step S280. At this time, since there is no unprocessed data in the pending data table, the determination in step S280 is not satisfied, and the process proceeds to step S285. Since there is unprocessed data in the data table, the determination in step S285 is satisfied and again The process returns to step S205.

  In this step S205, data relating to the data ID “DATA0005” which is the fifth record in the data table shown in FIG. 9 is read, and in the next step S210, a display application corresponding to the read data is displayed on the display terminal. It is determined whether or not the device 100 exists. Here, the extension corresponding to the data ID “DATA0005” is “jpg” as described above, and the display application exists in the display terminal device 100. Therefore, the determination in step S210 is satisfied and the process proceeds to step S215.

  In step S215, the data ID “DATA0005” corresponding to the read data is added along with the display time in the third display order of the display control information table shown in FIG. As a result, the display control information table is in a state where three records relating to the data IDs “DATA0001”, “DATA0002”, and “DATA0005” are registered. At this time, since there is data in the pending data table, the determination at the next step S245 is satisfied, and the routine goes to step S250.

  In step S250, data related to the data ID “DATA0003” is read from the pending data table. In the next step S255, the total “3 + 3 + 3 = 9” seconds of the display time of the registered data at this time is calculated. Since the total time is not longer than the acquisition time “14” seconds of the display application corresponding to the application ID “AP0004”, the determination in step S265 is not satisfied, and the process proceeds to step S280. Then, the processing of step S250 to step S280 is executed again for the data related to the other data ID “DATA0004” registered in the pending data table, and the process proceeds to step S285. Since unprocessed data exists in the data table, the determination in step S285 is satisfied, and the process returns to step S205 again.

  In this step S205, data relating to the data ID “DATA0006” which is the sixth record in the data table shown in FIG. 9 is read, and in the next step S210, a display application corresponding to the read data is displayed on the display terminal. It is determined whether or not the device 100 exists. Here, the extension corresponding to the data ID “DATA0006” is “pdf”, and referring to the display application list information table shown in FIG. 8, the application presence / absence flag corresponding to the application ID “AP0007” of the extension “pdf” is shown. Is “present”, the display application exists in the application storage unit 107 of the display terminal device 100. Therefore, the determination in step S210 is satisfied and the process proceeds to step S215.

  In step S215, the data ID “DATA0006” corresponding to the read data is added together with the display time in the fourth display order of the display control information table shown in FIG. As a result, four records relating to the data IDs “DATA0001”, “DATA0002”, “DATA0005”, and “DATA0006” are registered in the display control information table. At this time, since there is data in the pending data table, the determination at the next step S245 is satisfied, and the routine goes to step S250.

  In step S250, data related to the data ID “DATA0003” is read from the pending data table. In the next step S255, the total “3 + 3 + 3 + 3 = 12” seconds of display time of registered data at this time is calculated. Since the total time is not longer than the acquisition time “14” seconds of the display application corresponding to the application ID “AP0004”, the determination in step S265 is not satisfied, and the process proceeds to step S280. Then, the processing of step S250 to step S280 is executed again for the data related to the other data ID “DATA0004” registered in the pending data table, and the process proceeds to step S285. Since unprocessed data exists in the data table, the determination in step S285 is satisfied, and the process returns to step S205 again.

  In this step S205, data relating to the data ID “DATA0007” which is the seventh record in the data table shown in FIG. 9 is read, and in the next step S210, the display application corresponding to the read data is displayed on the display terminal. It is determined whether or not the device 100 exists. Here, the extension corresponding to the data ID “DATA0007” is “j2k”, and referring to the display application list information table shown in FIG. 8, the application presence / absence flag corresponding to the application ID “AP0006” of the extension “j2k” is shown. Is “None”, the display application does not exist in the application storage unit 107 of the display terminal device 100. Accordingly, the determination at step S210 is not satisfied, and the routine goes to step S220.

  As described above, the determinations in step S220 and step S225 are satisfied, and the routine goes to step S230. Since the display application corresponding to the extension “j2k” and the application ID “AP0006” is not registered in the display application acquisition order table, the determination is not satisfied, and the routine goes to Step S235. In step S235, the extension “j2k” and the application ID “AP0006” of the corresponding display application are added to the display application acquisition order table. As a result, the display application acquisition order table is in a state where two records relating to the extension “gif” and the extension “j2k” are registered, that is, the state shown in FIG.

  In the next step S240, the corresponding data ID “DATA0007” is added to the pending data table together with the display time “3” seconds. As a result, the pending data table is in a state where three records associated with the data IDs “DATA0003”, “DATA0004”, and “DATA0007” are registered, that is, the state shown in FIG.

  Since there is data in the pending data table at this time, the determination in the next step S245 is satisfied and the process proceeds to step S250, and the data associated with the data ID “DATA0003” is read from the pending data table. Since the registration contents of the display control information table are not changed from the above, the total display time of the registration data is “3 + 3 + 3 + 3 = 12” seconds. Since the total time is not longer than the acquisition time “14” seconds of the display application corresponding to the application ID “AP0004”, the determination in step S265 is not satisfied, and the process proceeds to step S280.

  In step S280, since there are unprocessed data IDs “DATA0004” and “DATA0007” in the pending data table, the determination is satisfied and the process returns to step S250. Then, the processing of step S250 to step S280 is executed again for the data associated with the next data ID “DATA0004”. The acquisition time of the display application corresponding to the application ID “AP0004” is “14” seconds, which is longer than the total display time of registration data “3 + 3 + 3 + 3 = 12” seconds, so the result is the same as described above, and the process proceeds to step S280 again. .

  In step S280, since there is data related to the unprocessed data ID “DATA0007” in the pending data table, the determination is satisfied and the routine returns to step S250. Then, the processing of step S250 to step S280 is executed again for the data related to the next data ID “DATA0007”. The acquisition time of the display application corresponding to the application ID “AP0006” is “15” seconds, which is longer than the total display time of registered data “3 + 3 + 3 + 3 = 12” seconds, so the same result as described above is obtained, and the process proceeds to step S280 again. .

  At this time, since there is no unprocessed data in the pending data table, the determination in step S280 is not satisfied, and the process proceeds to step S285. Since there is unprocessed data in the data table, the determination in step S285 is satisfied and again The process returns to step S205.

  In this step S205, data relating to the data ID “DATA0008” which is the eighth record in the data table shown in FIG. 9 is read, and in the next step S210, the display application corresponding to the read data is displayed on the display terminal. It is determined whether or not the device 100 exists. Here, since the extension corresponding to the data ID “DATA0008” is “jpg” as described above, and the display application exists in the display terminal device 100, the determination in step S210 is satisfied, and the process proceeds to step S215. .

  In step S215, the data ID “DATA0008” corresponding to the read data is added along with the display time to the fifth display order in the display control information table shown in FIG. As a result, five records relating to the data IDs “DATA0001”, “DATA0002”, “DATA0005”, “DATA0006”, and “DATA0008” are registered in the display control information table. At this time, since there is data in the pending data table, the determination at the next step S245 is satisfied, and the routine goes to step S250.

  In step S250, data related to the data ID “DATA0003” is read from the pending data table. In the next step S255, the total “3 + 3 + 3 + 3 + 3 = 15” seconds of display time of the registered data at this time is calculated. Since the total time is equal to or longer than the acquisition time “14” seconds of the display application corresponding to the application ID “AP0004”, the determination in step S265 is satisfied, and the process proceeds to step S270.

  In step S270, the data ID “DATA0003” corresponding to the data read from the reserved data table is added along with the display time to the sixth display order in the display control information table. In the next step S275, the data ID “DATA0003” and the display time are deleted from the pending data table.

  In the next step S280, since the data related to the unprocessed data IDs “DATA0004” and “DATA0007” exist in the pending data table, the determination is satisfied and the process returns to step S250. Since the extension of the data ID “DATA0004” is the same as that of the data ID “DATA0003”, the total display time of the registration data calculated in step S255 is the same result as above, and as a result, the determination in step S265 is performed. Is satisfied, and in step S270, the corresponding data ID “DATA0004” is added together with the display time to the seventh display order in the display control information table. In the next step S275, the data ID “DATA0004” and the display time are deleted from the pending data table. As a result, the pending data table is in a state where only one record relating to the data ID “DATA0007” is registered.

  In the next step S280, since there is data related to the unprocessed data ID “DATA0007” in the pending data table at this time, the determination is satisfied and the process returns to step S250 again. The data related to “DATA0007” has a different extension from the data IDs “DATA0003” and “DATA0004”, and therefore the total display time of the registration data calculated in step S255 is different. That is, here, the total “3 + 3 = 6” seconds of the display times for the two data IDs “DATA0003” and “DATA0004” newly registered in the display control information table is calculated. Since the total display time “3 + 3 = 6” seconds is not longer than the acquisition time “15” seconds of the display application corresponding to the application ID “AP0006”, the determination in step S265 is not satisfied and the process proceeds to step S280 again. At this time, since there is no unprocessed data in the pending data table, the determination in step S280 is not satisfied, and the process proceeds to step S285. Since there is unprocessed data in the data table, the determination in step S285 is satisfied and again The process returns to step S205.

  After that, regarding the data related to the data IDs “DATA0009” and “DATA0010” which are the records in the ninth and tenth rows in the data table shown in FIG. In step S215, corresponding data IDs are sequentially added to the display order 8th and 9th in the display control information table together with the display time. During this time, the total display time of the data registered in the display control information table does not exceed the display application acquisition time “15” seconds corresponding to the application ID “AP0006” registered in the pending data table. Is not satisfied.

  Then, when processing the data related to the data ID “DATA0011”, which is the 11th record in the data table shown in FIG. 9, the corresponding data ID is displayed in the 10th display order of the display control information table in step S215. When added with time, the total display time of the data registered in the display control information table is “3 + 3 + 3 + 3 + 3 = 15” seconds, and the display application acquisition time corresponding to the application ID “AP0006” registered in the hold data table “15” seconds or more. As a result, in the same manner as described above, the corresponding data ID “DATA0011” is added to the display order 11th in the display control information table together with the display time in step S270. In the next step S275, the data ID “DATA0011” and the display time are deleted from the pending data table. As a result, the pending data table becomes empty.

  Thereafter, the same processing is performed on the data relating to the data ID “DATA0012”, which is the 12th record in the data table shown in FIG. The extension corresponding to the data ID “DATA0012” is “gif” as described above, and the display application does not exist in the application storage unit 107 of the display terminal device 100. The corresponding data ID “DATA0012” is added with the display time “3” seconds. After that, the data ID “DATA0012” has the same extension as the above-mentioned data ID “DATA0003”, so the total display time of the registration data calculated in step S255 is the same result as the data ID “DATA0003”. As a result, the determination in step S265 is satisfied. In step S270, the corresponding data ID “DATA0012” is added to the display order 12th in the display control information table together with the display time. Thereafter, the determination in step S285 is satisfied, and the process returns to step S205 again.

  Further, for the data related to the data ID “DATA0013”, which is the 13th record in the data table shown in FIG. 9, the corresponding display application exists in the display terminal device 100, so that the corresponding data ID in step S215. Is added together with the display time to the 13th display order in the display control information table. As a result, the display control information table and the display application acquisition order table are in the states shown in FIGS.

  Thereafter, the data display process in step S300 shown in FIG. 6 and the display application acquisition process in step S400 shown in FIG. 7 are executed simultaneously. That is, in the data display process, a plurality of display data is displayed according to the display order of the display control information table set by the display control information setting process. In the display application acquisition process, the display application is acquired from the server 200 according to the acquisition order of the display application acquisition order table set by the display control information setting process. As a result, the display application related to the extension “gif” of the data IDs “DATA0003” and “DATA0004” is acquired while the expandable data from the first to the fifth display order is displayed in the display control information table. The sixth and seventh unexpandable data can be displayed without waiting for the operator. Furthermore, while the 6th and 7th unexpandable data that can be displayed and the 8th to 10th expandable data are displayed, the data ID “DATA0007” has an extension “j2k”. The display application can be acquired, and the 11th unexpandable data can be displayed without waiting for the operator.

  In the display terminal device 100 according to the embodiment described above, the data ID and display order of a plurality of display data to be displayed as a slide show are stored in the table storage unit 106 as a display control information table. When the operator instructs the operation unit 102 to start the slide show display, the control circuit 104 refers to the display application list information table acquired from the server 200 in step S210, and a plurality of displays whose data IDs are included in the display control information table. Based on the extension of each data, it is determined whether or not display data that cannot be developed by the display terminal device 100 is included in the plurality of display data.

  Here, the expandable data can be expanded so as to be displayed using the display application stored in the application storage unit 107, but the unexpandable data can be displayed in the display application stored in the application storage unit 107. It cannot be deployed. Therefore, when it is determined that display data that cannot be expanded is included, it is necessary to acquire a display application for expanding the data that cannot be expanded at any timing.

  In this embodiment, in such a case, after the control circuit 104 of the display terminal device 100 determines the acquisition time required for acquiring the display application in step S260, display control is performed based on the acquisition time in step S270. A display order of a plurality of display data in the information table is determined. As a result, the display order can be determined so that the acquisition of the display application for the unexpandable data is completed while the expandable data is displayed first while the unexpandable data is displayed later. . By doing in this way, acquisition of the display application for unexpandable data can be performed during execution of a slide show using expandable data. Accordingly, it is possible to provide a comfortable slide show that does not give the operator an unpleasant feeling due to the waiting time.

  In the present embodiment, in particular, the control circuit 104 of the display terminal apparatus 100 acquires a display application necessary for developing unexpandable data while the expandable data is displayed on the display unit 101 in step S270. The display order of the plurality of display data in the display control information table is determined so as to be completed. As a result, it is possible to acquire a display application for developing unexpandable data in a displayable manner during execution of a slide show using at least one expandable data. Accordingly, it is possible to provide a comfortable slide show that does not give the operator an unpleasant feeling due to the waiting time.

  In the present embodiment, in particular, in the display control information setting process in step S200, the data ID of the display data arranged in a predetermined initial order in the data table indicates that the unexpandable data is delayed and the expandable data is preceded. While being displayed, the order is changed so that acquisition of the display application for the unexpandable data is completed and the display control information table is incorporated. As a result, when the display unit 101 executes a slide show display based on the display control information table, it is possible to reliably acquire a display application for unexpandable data during execution of the slide show using the expandable data.

  In the present embodiment, in particular, in step S220, the control circuit 104 determines whether or not an acquisition time required for acquiring a display application necessary for display data expansion is equal to or less than a predetermined threshold. As a result, it is possible to exclude unexpandable data from being displayed so that the acquisition time of the display application for expansion is excessively long and the display application cannot be acquired during the execution of the slide show using the expandable data. it can. As a result, it is possible to reliably prevent the operator from feeling uncomfortable due to the waiting time.

  In the present embodiment, in particular, the control circuit 104 determines whether or not a display application required for display data expansion conforms to the specifications of the display terminal device 100 in step S225. As a result, it is possible to exclude unexpandable data that cannot be expanded during the execution of the slide show from the display target because the specifications of the display terminal device 100 do not correspond to the display application to be expanded. As a result, it is possible to reliably prevent the operator from feeling uncomfortable due to the waiting time.

  In the present embodiment, in particular, in step S275, the control circuit 104 deletes the display application acquired from the server 200 in order to expand the unexpandable data after the expansion of the data is completed. Thereby, the acquired display application does not occupy the memory and storage of the display terminal device 100 constantly. As a result, the storage area provided in the display terminal device 100 can be saved.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described in order.

(1) When changing the display time In the above embodiment, the display order of a plurality of display data to be displayed as a slide show is changed, so that the operator does not feel uncomfortable due to the waiting time. For example, if the slide show display is a presentation in which the order is determined or has a story like a growth album, there may be a need not to change the display order. In such a case, the display time may be changed without changing the display order.

  The detailed content of the display control information setting process in step S500 in this modification will be described with reference to FIG. Note that the control contents other than the display control information setting process in step S500, which are executed by the control circuit 104 of the display terminal device 100 according to the present modification, are the same as those in the above-described embodiment shown in FIGS. It is the same as that shown in. At this time, the control content shown in FIG. 3 is obtained by replacing step S200 with step S500 described below.

  First, in step S <b> 505, the control circuit 104 reads one data from the data table stored in the table storage unit 106. Hereinafter, in the description of the flowchart in FIG. 13, one piece of data read here is appropriately referred to as “data C”.

  Next, in step S510, the control circuit 104 determines whether or not a display application for expanding the display data corresponding to the read data C so as to be displayed exists in the application storage unit 107. If the display application corresponding to the data C exists in the application storage unit 107, the determination is satisfied, and the routine goes to Step S560 described later. On the other hand, if the display application corresponding to the data C does not exist in the application storage unit 107, the determination is not satisfied, and the routine goes to Step S515.

  In step S515, the control circuit 104 determines whether or not the acquisition time required for acquiring the display application necessary for expanding the display data corresponding to the data C is equal to or less than a predetermined threshold value. If the acquisition time is greater than the threshold, it is assumed that the acquisition time of the display application is excessively long and the acquisition cannot be performed during the execution of the slide show, and the determination is not satisfied, and the process proceeds to step S565 described later. On the other hand, if the acquisition time is less than or equal to the threshold, the determination is satisfied and the routine goes to Step S520.

  In step S520, the control circuit 104 determines whether or not the display application necessary for expanding the display data corresponding to the data C conforms to the specifications of the display terminal device 100. If the corresponding display application does not conform to the specifications of the display terminal device 100, the determination is not satisfied and the routine goes to Step S565 described later. On the other hand, if the corresponding display application conforms to the specifications of the display terminal device 100, the determination is satisfied, and the routine goes to Step S525.

  In step S525, the control circuit 104 determines whether or not a display application necessary for expanding the display data corresponding to the data C is registered in the display application acquisition order table stored in the table storage unit 106. If the corresponding display application is registered in the display application acquisition order table, the determination is satisfied, and the routine goes to Step S560 described later. On the other hand, if the corresponding display application is not registered in the display application acquisition order table, the determination is not satisfied, and the routine goes to Step S530.

  In step S530, the control circuit 104 adds the extension and application ID of the display application corresponding to the data C to the display application acquisition order table stored in the table storage unit 106.

  In step S535, the control circuit 104 refers to the display application list information table acquired from the server 200 in step S100 and stored in the table storage unit 106, and expands the display data corresponding to the read data C so as to be displayed. The acquisition time for acquiring the display application for acquiring from the server 200 is acquired. Hereinafter, in the description of the flowchart in FIG. 13, the acquired acquisition time is appropriately referred to as “time C”. As described above, this acquisition time may be calculated and determined as needed according to the communication environment between the display terminal device 100 and the server 200.

  In step S540, the control circuit 104 calculates the average display time by dividing the acquired time C by the number of data registered in the pending data table at this time. Hereinafter, in the description of the flowchart in FIG. 13, the calculated average display time is appropriately referred to as “time D”.

  In step S545, the control circuit 104 registers the calculated time D in the respective display time fields for all data registered in the pending data table. Thereby, the display time of each display data is set to time D.

  In step S550, the control circuit 104 adds all the data registered in the pending data table to the display control information table. In next step S555, the control circuit 104 deletes all data registered in the pending data table.

  In the next step S560, the control circuit 104 adds the data ID corresponding to the data C together with the display time to the pending data table stored in the table storage unit 106.

  In step S565, the control circuit 104 refers to the data table stored in the table storage unit 106, and determines whether or not unprocessed data exists in the data table. If unprocessed data exists, the determination is satisfied and the routine returns to the previous step S505. On the other hand, if there is no unprocessed data, the determination is not satisfied and the routine goes to the next step S570.

  In step S570, the control circuit 104 registers the basic display time in each display time field for all data registered in the pending data table at this time. This basic display time is a common display time initially set for each display data.

  In step S575, the control circuit 104 adds all the data registered in the hold data table to the display control information table, as in step 550. In the next step S580, the control circuit 104 deletes all the data registered in the pending data table in the same manner as in step 555. Thereby, this subroutine is completed.

  Next, the control content described above will be described using the specific examples shown in FIGS. The display control information table and the pending data table shown in FIGS. 14 and 15 are in a state where nothing is registered at the start of the display control information setting process in step S500 as described above. The display application list information table, the data table, and the display application acquisition order table will be described as being the same as those shown in FIGS. 8, 9, and 12 described above.

  In the display terminal device 100, when the operator gives an instruction to start slide show display, the determination in step S10 shown in FIG. 3 is satisfied, and the process proceeds to step S100. In the display application list acquisition process shown in FIG. Is displayed from the server 200 and stored in the table storage unit 106 of the display terminal device 100.

  Next, the display control information setting process in step S500 shown in FIG. 13 is executed. First, in step S505, data relating to the data ID “DATA0001” which is the first record in the data table shown in FIG. 9 is read, and in the next step S510, display data corresponding to the read data can be displayed. It is determined whether or not a display application to be expanded in the application storage unit 107 exists. As described above, the extension corresponding to the data ID “DATA0001” is “jpg”, and the display application corresponding to the extension exists in the application storage unit 107 of the display terminal device 100. Therefore, the determination at step S510 is satisfied, and the routine goes to step S560.

  In step S560, the data ID “DATA0001” corresponding to the read data is added to the pending data table shown in FIG. 15 together with the display time. Although FIG. 15 shows a state in which the display time has been changed, the basic display time described above is registered at this point. In this modification, the basic display time is set to “2” seconds.

  In the next step S565, it is determined whether or not unprocessed data exists in the data table. At this point in time, data other than the data associated with the data ID “DATA0001” has not been processed, so the determination is satisfied and the routine returns to step S505.

  In step S505, data relating to the data ID “DATA0002” which is the second record in the data table shown in FIG. 9 is read, and the same processing is performed. Since the extension corresponding to the data ID “DATA0002” is “jpg” as described above, the data ID “DATA0002” corresponding to the read data is displayed in the reserved data table shown in FIG. Is added along with the display time. As a result, two data relating to the data IDs “DATA0001” and “DATA0002” are registered in the pending data table. Thereafter, the determination in step S565 is satisfied, and the process returns to step S505.

  In step S505, data relating to the data ID “DATA0003”, which is the third record in the data table shown in FIG. 9, is read. In the next step S510, the display application corresponding to the read data is displayed on the display terminal. It is determined whether or not the device 100 exists. As described above, the extension corresponding to the data ID “DATA0003” is “gif”, and the corresponding display application does not exist in the application storage unit 107 of the display terminal device 100. Therefore, the determination at step S510 is not satisfied, and the routine goes to step S515.

  As described above, the determinations in steps S515 and S520 are satisfied, and the process proceeds to step S525. In this step S525, it is determined whether or not a display application corresponding to the application ID “AP0004” is registered in the display application acquisition order table. At this time, data is still registered in the display application acquisition order table. Therefore, the determination is not satisfied and the routine goes to Step S530. In step S530, the extension “gif” and the application ID “AP0004” of the corresponding display application are added to the display application acquisition order table.

  In the next step S535, an acquisition time for acquiring a corresponding display application from the server 200 with reference to the display application list information table is acquired. Here, the acquisition time “14” seconds of the display application corresponding to the application ID “AP0004” is acquired.

  In the next step S540, the average display time “7” seconds is calculated by dividing the acquired time “14” seconds by the number of data “2” registered in the pending data table at this time. In step S545, the calculated time “7” seconds is registered in each display time field for all data registered in the hold data table. As a result, each display time is extended from “2” seconds to “7” seconds, which is the basic display time, and the pending data table is in the state shown in FIG.

  In the next step S550, all data contents of the pending data table are added to the display control information table. As a result, the data IDs “DATA0001” and “DATA0002” are registered with the display time “7” seconds in the first and second display orders of the display control information table, respectively. In step S555, all data in the pending data table is deleted.

  In the next step S560, the corresponding data ID “DATA0003” is added to the pending data table together with the basic display time “2” seconds. Thereafter, the determination in step S565 is satisfied, and the process returns to step S505.

  In step S505, data relating to the data ID “DATA0004”, which is the fourth record in the data table shown in FIG. 9, is read. Since the extension corresponding to the data ID “DATA0004” is “gif” and the corresponding display application does not exist in the application storage unit 107 of the display terminal device 100, the determination in step S510 is not satisfied and the process proceeds to step S515. .

  As described above, the determinations in steps S515 and S520 are satisfied, and the process proceeds to step S525. At this time, since the display application corresponding to the application ID “AP0004” is registered in the display application acquisition order table, the determination is satisfied, and the routine goes to Step S560. In this step S560, the corresponding data ID “DATA0004” is added to the pending data table together with the basic display time “2” seconds. Thereafter, the determination in step S565 is satisfied, and the process returns to step S505.

  After that, regarding the data related to the data IDs “DATA0005” and “DATA0006” that are the records in the fifth and sixth rows in the data table shown in FIG. In step S560, data IDs “DATA0005” and “DATA0006” are sequentially added to the pending data table together with the basic display time “2” seconds. As a result, four data relating to the data IDs “DATA0003”, “DATA0004”, “DATA0005”, and “DATA0006” are registered in the pending data table. Thereafter, the determination in step S565 is satisfied, and the process returns to step S505.

  In this step S505, data relating to the data ID “DATA0007”, which is the seventh record in the data table shown in FIG. 9, is read. Since the extension corresponding to the data ID “DATA0004” is “j2k” and the corresponding display application does not exist in the application storage unit 107 of the display terminal device 100, the determination in step S510 is not satisfied and the process proceeds to step S515. .

  As described above, the determinations in steps S515 and S520 are satisfied, and the process proceeds to step S525. In this step S525, it is determined whether or not the display application with the application ID “AP0007” corresponding to the extension “j2k” is registered in the display application acquisition order table, but since it is not registered at this time, The determination is not satisfied and the routine goes to Step S530. In step S530, the extension “j2k” and the application ID “AP0007” of the corresponding display application are added to the display application acquisition order table.

  In the next step S535, an acquisition time for acquiring a corresponding display application from the server 200 with reference to the display application list information table is acquired. Here, the acquisition time “15” seconds of the display application corresponding to the application ID “AP0007” is acquired.

  In the next step S540, the average display time “4” seconds is calculated by dividing the acquired time “15” seconds by the number of data “4” registered in the pending data table at this time. At this time, if it is not divisible, it is rounded up. In step S545, the calculated time “4” seconds is registered in each display time field for all data registered in the pending data table. Thereby, each display time is extended from “2” seconds to “4” seconds of the basic display time.

  In the next step S550, all data contents of the pending data table are added to the display control information table. As a result, the data IDs “DATA0003”, “DATA0004”, “DATA0005”, and “DATA0006” are registered together with the display time “4” seconds in the third to sixth display orders of the display control information table. In step S555, all data in the pending data table is deleted.

  In the next step S560, the corresponding data ID “DATA0007” is added to the pending data table together with the basic display time “2” seconds. Thereafter, the determination in step S565 is satisfied, and the process returns to step S505.

  After that, regarding the data related to the data IDs “DATA0008” to “DATA0011” that are records in the eighth to eleventh rows in the data table shown in FIG. In step S560, the data IDs “DATA0008” to “DATA0011” are sequentially added to the pending data table together with the basic display time “2” seconds. Thereafter, the determination in step S565 is satisfied, and the process returns to step S505.

  Thereafter, for the data related to the data ID “DATA0012”, which is the 12th record in the data table shown in FIG. 9, the extension is “gif” and the corresponding display application is the application storage unit 107 of the display terminal device 100. Therefore, the determination at step S510 is not satisfied, and the routine goes to step S515. Since the display application corresponding to the application ID “AP0004” is registered in the display application acquisition order table, the determination in step S525 is satisfied, and the process proceeds to step S560. In this step S560, the corresponding data ID “DATA0012” is added to the pending data table together with the basic display time “2” seconds. Thereafter, the determination in step S565 is satisfied, and the process returns to step S505.

  After that, for the data related to the data ID “DATA0013”, which is the 13th row record in the data table shown in FIG. 9, the corresponding display application exists in the display terminal device 100, so in step S 560 the data is stored in the pending data table. The ID “DATA0013” is sequentially added with the basic display time “2” seconds.

  As described above, since the processing has been completed for all the data registered in the data table, the determination in the next step S565 is not satisfied and the process proceeds to step S570. In step S570, “2” seconds of the basic display time is registered in each display time field for all data registered in the pending data table at this time. In the next step S575, all data contents of the pending data table are added to the display control information table. As a result, the display control information table is in the state shown in FIG. In step S580, all data in the pending data table is deleted.

  In the above, step S505 functions as a reading unit described in the claims. In step S545, if the display data related to the data read in S505 is unexpandable data, the display data related to the expandable data read in the order before the read order and registered in the pending data table is displayed. Fixed so that the acquisition of the display application necessary for the development of the unexpandable data related to the read data is completed while the display unit 101 displays the expandable data related to the data ID for the data ID A display time that is longer than a predetermined average display time is given. Therefore, step S545 functions as a display determination unit described in the claims and corresponds to a display determination procedure.

  Step S510 functions as a data determination unit described in the claims and corresponds to a data determination procedure. Step S535 functions as an acquisition time determination unit and corresponds to an acquisition time determination procedure. Step S515 functions as an acquisition time determination unit and also functions as a first exclusion processing unit. Further, step S520 functions as a conformity determination unit described in the claims and also functions as a second exclusion processing unit.

  In the display terminal device 100 of the modified example described above, the data IDs and display times of a plurality of display data to be displayed as a slide show are stored in the table storage unit 106 as a display control information table. Then, when display data that cannot be expanded by the display terminal device 100 is included in the plurality of display data, the control circuit 104 of the display terminal device 100 determines the acquisition time required for acquiring the display application in step S535. In step S545, display times of a plurality of display data in the display control information table are determined based on the acquisition time. By extending the display time of expandable data to be displayed first and setting it so that the acquisition of the display application for unexpandable data to be displayed later can be completed during the display Time can be determined. By doing in this way, acquisition of the display application for unexpandable data can be performed during execution of a slide show using expandable data. Accordingly, it is possible to provide a comfortable slide show that does not give the operator an unpleasant feeling due to the waiting time.

  Further, in this modification, the basic display time for each display data is set so that the display application for unexpandable data is completed while the expandable data is displayed first with the extended display time, It is incorporated in the display control information table. As a result, when the display unit 101 executes a slide show display based on the display control information table, it is possible to reliably acquire a display application for unexpandable data during execution of the slide show using the expandable data.

(2) When sorting the data table in advance In the above, the display control information processing is directly performed on the data registered in the data table, but the data table is rearranged so as to satisfy a predetermined condition in advance. In addition, display control information processing may be performed. As this predetermined condition, for example, sorting may be performed by an extension related to a display application existing in the display terminal device 100, or may be sorted by an extension related to a display application having a short acquisition time, for example. Moreover, you may sort on conditions other than this.

  The content of control executed by the control circuit 104 of the display terminal device 100 according to the present modification will be described with reference to FIG. FIG. 16 shows a case where sorting is performed by the extensions related to the display application existing in the display terminal device 100 described above.

  Steps S10 and S100 are the same as those in FIG.

  In the next step S15, the control circuit 104 refers to the display application list information table acquired from the server 200 in step S100 and stored in the table storage unit 106, and the data corresponding to each record on the data table is Display applications that can expand the display data are sorted by the extension existing in the display terminal device 100.

  Subsequent steps S200, S300, S400, and S20 are the same as those in FIG.

  Next, an example of the data table sorted in the above step S15 will be described with reference to FIG. As shown in FIG. 17, data related to extensions “jpg”, “pdf”, and “png” whose application presence / absence flag is “present”, and extension “gif” whose application presence / absence flag is “none”, Data relating to “j2k” is sorted on the data table.

  By sorting the data table in advance in this way, it is possible to concentrate data that can be developed in advance in the first stage of the slide show and data that cannot be developed in the subsequent stage. As a result, it is easy to secure the acquisition time of the display application in the slide show, and the information processing in the subsequent display control information setting process can be simplified.

  Next, another control content executed by the control circuit 104 of the display terminal device 100 according to the present modification will be described with reference to FIG. FIG. 18 shows a case where sorting is performed according to extensions related to the display application with a short acquisition time described above.

  In step S15A of FIG. 18, the control circuit 104 refers to the display application list information table acquired from the server 200 in step S100 and stored in the table storage unit 106, and stores data corresponding to each record on the data table. The display data is sorted by extension with a short acquisition time of the display application that can expand the display data.

  Other processes are the same as those in FIG.

  Next, an example of the data table that has been sorted in step S15A will be described with reference to FIG. As shown in FIG. 19, data related to the extension “gif” whose acquisition time is relatively short and data related to the extension “j2k” whose acquisition time is relatively long are sorted on the data table.

By sorting the data table in advance in this way, display data with a relatively short acquisition time of the display application can be concentrated in the previous stage, and display data with a relatively long acquisition time of the display application can be concentrated in the subsequent stage. It becomes. As a result, it is easy to secure the acquisition time of the display application in the slide show, and the information processing in the subsequent display control information setting process can be simplified.
(3) Others In the above description, whether or not the read display data can be displayed on the display terminal device 100 is determined based on the extension of the data. The determination may be made using.

  In the above description, the case where the display order is changed and the case where the display time is changed are described separately. However, control may be performed by appropriately combining these. Alternatively, both modes may be provided in one display terminal device 100, and the operator may perform either control by switching the mode.

  In the above, the display application acquisition time becomes excessively long, so that the acquisition cannot be performed while the slide show is being executed, or the display application 100 is not compatible with the display application. However, when such display data exists, for example, preset display data may be displayed.

  In the above description, a case where a plurality of display data is displayed as a slide show has been described as an example. However, in addition to display data such as images, for example, a plurality of music data and a plurality of moving image data are continuously reproduced. The present invention is applicable.

  In addition, in the above, the arrow shown in FIG. 2 shows an example of a signal flow, and does not limit the signal flow direction. Further, the flowcharts shown in FIGS. 3 to 7, 13, 16, and 18 are not intended to limit the present invention to the procedures shown in the above-mentioned flow, and the procedures are not deviated from the spirit and technical idea of the invention. You may add / delete or change the order.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
