This allows information processing terminals 41, 42, and 43 belonging to company D 50 to display one of display contents D1, D2, D3, D4, D5, and so on stored in subfolders D1, D2, D3, D4, D5, and so on.

[0082] In addition, in this embodiment, as shown in Figure 2(a), the server 11 is provided with a public folder 11O (common content storage location) separate from the folder 11A for Company A (first content storage location), the folder 11B for Company B (second content storage location), the folder 11C for Company C (third content storage location), and the folder 11D for Company D (fourth content storage location).

[0083] The public folder 11O (common content storage location) is a folder (common content storage location) that can be accessed from broadcasting terminals 21, 22, and 23 belonging to company A 20, broadcasting terminals 31, 32, and 33 belonging to company B 30, information processing terminals 41, 42, and 43 belonging to company C 40, and information processing terminals 51, 52, 53, and 54 belonging to company D 50.

[0084] The public folder 11O stores content, such as advertising content, that can be broadcast and displayed on any of broadcast terminals 21, 22, and 23 belonging to company A 20, broadcast terminals 31, 32, and 33 belonging to company B 30, information processing terminals 41, 42, and 43 belonging to company C 40, and information processing terminals 51, 52, 53, and 54 belonging to company D 50.

[0085] Created in the hierarchy below public folder 11O are subfolders X for company X that provides advertisements, subfolder Y for company Y that provides advertisements, subfolder Z for company Z that provides advertisements, etc. Subfolder X stores advertisement content for company X, subfolder Y stores advertisement content for company Y, and subfolder Z stores advertisement content for company Z.

[0086] As the associated folder for the screen of the program created by the program creation section of the control unit in broadcasting terminals 21, 22, 23 belonging to company A 20, broadcasting terminals 31, 32, 33 belonging to company B 30, information processing terminals 41, 42, 43 belonging to company C 40, and information processing terminals 51, 52, 53, 54 belonging to company D 50, any of subfolders X, subfolder Y, subfolder Z, ... in the hierarchy below public folder 11O can be set.

[0087] This allows broadcast terminals 21, 22, 23 belonging to company A 20, broadcast terminals 31, 32, 33 belonging to company B 30, information processing terminals 41, 42, 43 belonging to company C 40, and information processing terminals 51, 52, 53, 54 belonging to company D 50 to function as advertising media.

[0088] If it can function as an advertising medium, it will be possible to develop it by offering incentives based on the number of times it is aired or displayed. An airing incentive is the amount of airing compensation per device set by the advertising content provider, and is paid, for example, when the number of times the content is aired reaches a specified number.

[0089] This will encourage companies operating the content display system of this embodiment to actively broadcast advertising content from other companies, creating an environment in which advertisements are displayed at the discretion of the digital signage operating company, rather than the advertising company, and creating opportunities to use general digital signage display surfaces that are not being used as advertising media as advertising media.

[0090] (Content display application) The content display application used in the content display system of this embodiment will be described with reference to Fig. 4 to Fig. 28. Fig. 4 is an operation flowchart of the content display application, and Fig. 5 to Fig. 27 are operation screens of the content display application. This content display application is used in signage mode operation and desktop mode operation.

[0091] The content display application of this embodiment is installed in broadcast terminals 21, 22, 23, 31, 32, and 33 and information processing terminals 41, 42, 43, 51, 52, 53, and 54 belonging to company A 20, company B 30, company C 40, and company D 50. Each operation by the content display application described below is executed by a control unit of the broadcast terminals 21, 22, 23, 31, 32, and 33 and information processing terminals 41, 42, 43, 51, 52, 53, and 54, for example, a program creation unit, a program display unit, and an option setting unit of control unit 21c and control unit 51c shown in FIG.

[0092] (Application launch) First, when the application is started (step S10), the title screen of the application shown in Fig. 5 is displayed (step S11). The title screen displays a "PLAY" button for starting signage broadcasting, an "EDIT" button for creating broadcast content, an "OPTIONS" button for setting options, and an "EXIT" button for closing the application.

[0093] (Broadcast content created by EDIT) To create broadcast content (step S12), click the "EDIT" button on the application startup screen as shown in FIG. 6(a) (step S13). The edit screen shown in FIG. 6(b) is displayed. A blank program list and a schedule view are displayed on the edit screen. A program is created using the edit screen (step S14).

[0094] When creating a program (step S14), a screen in the program is set (step S15), and a linked folder linked to the screen is set (step S16).

[0095] Furthermore, a program schedule is set (step S17). In setting the schedule (step S17), the broadcast date and time of the program are set (step S18). If multiple programs have been created, the broadcast priority of each program is set (step S19).

[0096] The details of creating the broadcast content carried out in steps S12 to S19 will be explained below. Note that circled numbers in the drawings will be represented as bracketed numbers ((1), (2), (3), . . . ).

[0097] (Edit screen) Details of the edit screen are shown in Figure 7. The edit screen consists of a Start Broadcast button (1) for closing the edit screen and starting the signage broadcast, a Back button (2) for returning to the title screen, a Program List (3) for displaying a list of the created screens, a Schedule View (4) that displays the broadcast contents according to the program broadcast time, day of the week, and priority, and an Add Program button (5) for adding a new program.

[0098] (Program List) FIG. 8 shows the details of program list (3) in FIG.

[0099] The program list displays, from left to right, a priority number (1) indicating the priority, an enable / disable toggle switch (2) which selects whether or not to broadcast the program, a program name (3) for entering and displaying the program name, thumbnails (4) which display the program layout (number of screens, position, size) as thumbnails, broadcast time (5) for setting and displaying the broadcast time for each program, broadcast day (6) for setting and displaying the broadcast day for each program, an add program button (7) for adding a program, an edit program button (8) for displaying the layout screen, a duplicate program button (9) for duplicating a program, a delete program button (10) for deleting a program, and a sort button (11) for changing the order in which the programs are displayed in the list.

[0100] (Schedule View) FIG. 9 shows the details of the schedule view (4) in FIG.

[0101] The schedule view displays the names of the programs to be aired in a matrix format with the days of the week on the horizontal axis and the times on the vertical axis, making it easy to visually check the schedule. Schedules set for the "broadcast time" and "broadcast day" of a program are immediately reflected in the schedule view.

[0102] (Program Creation) To create a program, click the "+" button to add a program, as shown in Figure 10(a). A "New Program" will be added to the program list, as shown in Figure 10(b). The added program will be saved as a "Program," including the broadcast time and broadcast day settings.

[0103] (adding, duplicating, deleting programs) As shown in Figure 11(a), click the "+" button to add another program. As shown in Figure 11(b), a "new program" is added to the program list.

[0104] As shown in Figure 11(c), click the program copy button (circle) of the program you want to copy. As shown in Figure 11(d), the program you want to copy will be copied and added above the original program.

[0105] As shown in Figure 11(e), click the program deletion button (circle) of the program you want to delete. As shown in Figure 11(f), the program you clicked will be deleted.

[0106] (Enable / disable programs) As shown in Figure 12(a), click the enable / disable toggle switch (circle) for the program you want to change. As shown in Figure 12(b), the program will be grayed out and removed from the broadcast list. At the same time, the program will also be removed from the schedule view and replaced with the program below the removed program.

[0107] In this state, if you click the enable / disable toggle switch (circle) again, the program you want to change will be enabled and will return to the state it was in before it was disabled.

[0108] (Program list priority) When multiple programs have overlapping broadcast times, the programs listed higher in the program list are determined to have higher priority and are broadcast preferentially. As shown in Figure 13(a), program 01 listed at the top has a higher priority than program 02 listed below it, which has a higher priority than program 03 listed below it.

[0109] The order of the program list can be changed using the up and down buttons, which allows you to change the priority of the programs. As shown in the top of Figure 13(b), you can change the order of the programs by clicking the up and down buttons displayed on the right side of the program list. As shown in the bottom of Figure 13(b), the up and down buttons consist of a button to move to the top, a button to move one step up, a button to move one step down, and a button to move to the bottom.

[0110] (Application of scheduling) In this embodiment, detailed scheduling can be performed within a one-week range using the program schedule and the priority of the program list.

[0111] As shown in Figure 14(a), if Program A (Program A is broadcast from 9:00 to 18:00 on Sundays and Tuesdays) and Program B (Program B is broadcast from 9:00 to 18:00 on Sundays, Mondays, and Tuesdays) have the priority of Program A and Program B, then Program A will be broadcast from 9:00 to 18:00 on Sundays, Program B will be broadcast from 9:00 to 18:00 on Mondays, Program A will be broadcast from 9:00 to 18:00 on Tuesdays, and nothing will be broadcast from 9:00 to 18:00 on Wednesdays.

[0112] If the program schedule in Figure 14(a) is changed to show the broadcast time of Program B all day, as shown in Figure 14(b), Program A is set to broadcast from 9:00 to 18:00 on Sundays, and Program B is set to broadcast all day, so Program A, which has a higher priority, will be broadcast from 9:00 to 18:00 on Sundays, and Program B will be broadcast during the other time periods of 0:00 to 9:00 and 18:00 to 24:00.

[0113] (Schedule settings) The details of setting the program schedule will now be described.

[0114] When you save a program on the edit screen, the program will be added with a schedule set to air "all days of the week" and "all day." You can change the "day" and "time" for each program.

[0115] The broadcast time of a program is set in the broadcast time item, as shown in Figure 15(a). The initial setting is "all day" broadcast. Set the broadcast time by setting the start and end times. Checking the box will set it to broadcast all day. Multiple broadcast times cannot be set for a single program. If you want to broadcast a program at multiple broadcast times, duplicate the program and set different broadcast times.

[0116] The broadcast days of the program are set in the broadcast day item, as shown in Figure 15(b). By default, all days of the week are broadcast days. Click on the target day of the week to set whether or not to broadcast the program. In Figure 15(b), the broadcast days are Sunday, Tuesday, Thursday, Friday, and Saturday.

[0117] (Edit Screen) To edit a screen, click the Edit Program button (circle) for the program you want to edit, as shown in Figure 16(a). The Edit screen will close and the Screen Edit screen will appear, as shown in Figure 16(b).

[0118] (Screen details) The details of the screen editing screen are shown in Figs. 17(a) and (b).

[0119] The screen editing screen displays a back button (1) for returning to the edit screen, a screen settings button (2) for displaying and editing property information such as the linked folder referenced by the screen, an add screen button (3) for adding a screen, a move to back button (4) for moving the screen to the back of other screens, a snap layout button (5) for opening the snap layout screen, a delete screen button (6) for deleting the target screen, a screen position size button (7) for displaying the starting position of the screen (top left coordinates of the screen) and pixel size, and a snap button (8) for aligning the screen to other screens or the edges of the screen.

[0120] (Screen Settings: Linked Folder Settings) In this embodiment, a link folder can be set on the screen. A link folder is a folder for storing files of content to be displayed on the screen. By storing files in the link folder, desired content can be displayed on the screen.

[0121] A method for setting a linked folder on a screen will be described with reference to FIGS.

[0122] Double-clicking on the area where the screen setting information is displayed will display the screen setting screen.

[0123] Details of the screen setting screen are shown in Figures 18(a) and (b).

[0124] The screen settings screen has a linked folder settings field (1) for setting linked folders, a broadcast settings field (2) for setting the number of seconds for broadcast, a still image display settings field (3) for setting still image display, a video settings field (4) for setting video display, a PDF display settings field (5) for setting PDF display, a text display settings field (6) for setting text display, and a coordinate settings field (7) for setting the screen coordinates.

[0125] In the linked folder setting field (1), you can set the location of the linked folder and the broadcast order. The linked folder is set by its folder name, for example, "C:\Users\folderingcontents."

[0126] As shown in Figure 19(a), when you click the select button in the upper right corner of the screen setting screen, the Explorer screen shown in Figure 19(b) will be displayed, and you can set the linked folder by selecting the folder you want to set.

[0127] The broadcast order can be selected from file name (ascending or descending) or file update date and time (ascending or descending). If file name ascending order is selected, the files in the linked folder will be broadcast on the screen in ascending order of their file names.

[0128] In the Broadcast Settings section (2), you can set the number of seconds to broadcast for non-video content. This sets the number of seconds to broadcast when displaying still images, PDFs (when displaying each page as a still image), and web content. The number of seconds to broadcast is set per screen. Note that videos will continue to run regardless of the number of seconds set.

[0129] In the still image display setting field (3), you can set whether to maintain the aspect ratio of the still image to be displayed. If you select "maintain," the still image in the file will be displayed on the screen while maintaining its aspect ratio. If you select "not maintain," the still image in the file will be displayed according to the aspect ratio of the screen.

[0130] In the Video Settings section (4) for setting the video display, you can set whether to maintain the aspect ratio of the video to be displayed. If you select "maintain," the video file will be displayed on the screen while maintaining its aspect ratio. If you select "not maintain," the video file will be displayed according to the aspect ratio of the screen.

[0131] In the PDF display setting field (5) for setting PDF display, you can set whether to display the PDF file as a still image for each page or as a PDF file itself.

[0132] In the text display setting field (6), you can set how to display text files, such as the font to display the text, the text color, transparency, the text background color, transparency, whether to move the text, the direction in which the text moves, and the speed at which the text moves.

[0133] When you set text to "Move," you can set the direction of movement, such as "Right to Left," "Left to Right," "Top to Bottom," or "Bottom to Top." These settings are per screen.

[0134] In the coordinate setting field (7) for setting the screen coordinates, you set the start coordinates and size of the screen. As shown in Figure 20, you can set the screen's placement position and size numerically. In Figure 20, X is the start coordinate (horizontal) of the screen based on the top left of the screen, Y is the start coordinate (vertical) of the screen based on the top left of the screen, W is the screen's width (px), and H is the screen's height (px).

[0135] (Add screen) Adding a screen will be described with reference to FIG.

[0136] To add a screen, click the add button + (circle) in the upper right corner of Screen 1, as shown in Figure 21(a). "Screen 2" will be added to the program list, as shown in Figure 21(b). Up to five screens can be added to one program.

[0137] (Delete Screen) To delete a screen, click the Delete button in the upper right corner of the screen you want to delete. The screen whose Delete button you clicked will be deleted.

[0138] (Screen movement) The movement of the screen will be explained with reference to FIG.

[0139] To move the screen, click and hold anywhere on the screen other than the icons to move the screen.

[0140] When changing the size of the screen, the screen size can be changed by dragging the four corners or four sides of the screen, as shown in FIG. 22(a).

[0141] If you want to resize the screen to fit your screen or another screen, you can click the screen snap button (circle) to resize it to fit the edge of the desktop or the edge of another screen, as shown in Figure 22(b).

[0142] By using the snap button, you can lay out the screens without any gaps, as shown in Figure 22(c). In Figure 22(c), screen 2 is laid out without any gaps below screen 1, screen 4 is laid out without any gaps below screen 3, and screens 3 and 4 are laid out without any gaps next to screens 1 and 2.

[0143] (Snap layout function) The snap layout function will be described with reference to FIG.

[0144] When laying out multiple screens, it is necessary to make detailed size adjustments for each screen to achieve the desired layout. The snap layout function makes it easy to configure program layouts without having to make detailed size adjustments for each screen.

[0145] As shown in Figure 23(a), when you click the snap layout button (circle) on the top right of the screen, the snap layout screen pops up.

[0146] In Figure 23(a), nine 3x3 layouts are displayed. The top left layout is a one-screen layout. The middle left, bottom left, and top center layouts are two-screen layouts. The middle center and bottom center layouts are three-screen layouts. The top right, middle right, and bottom right layouts are four-screen layouts.

[0147] As shown in Figure 23(b), when you select one of the nine layouts and click on a screen within that layout, the position and size of the screen you are editing will change to match that of the screen in that layout.

[0148] In Figure 23(b), a layout consisting of three screens in the middle of nine layouts is selected, and the center screen of the three screens is clicked. As a result, the position and size of Screen 1 are automatically adjusted so that it becomes the center screen of the selected layout.

[0149] (Screen layout example) In this embodiment, as shown in FIG. 24(a), a maximum of five screens can be arranged.

[0150] In this embodiment, it is also possible to have a layout in which screens are overlapped, as shown in Fig. 24(b). In Fig. 24(b), screens 2 and 3 are overlapped on top of screen 1. After screen 1 is laid out, screen 2 is overlapped and laid out and saved, and then screen 3 is overlapped and laid out and saved. The overlapping order at the time of saving will be the overlapping order at the time of broadcast.

[0151] (Finish and save screen editing) To finish screen editing, click the back button (←) displayed on the foreground screen. In Figure 24(b), the back button (←) is displayed on the top left of the foreground screen 3. When screen editing is finished, the program as it was at that time is saved and you are returned to the edit screen.

[0152] (PDF file display settings) The display settings for a PDF file will be explained with reference to FIGS. 25 and 26.

[0153] If the PDF file is a multi-page PDF, you can choose between two display methods.

[0154] As shown in Figure 25(a), if you select "Display each page as a still image," the PDF file will be converted into a still image for each page, and the converted still images will be displayed by switching between them. The images for each page will switch every number of seconds set in "Display seconds."

[0155] As shown in Figure 25(b), if you select "Display PDF file as is," the file will be displayed in PDF format. When displaying the file in PDF format, it is recommended that you operate the device in an environment where touch operations are possible. In an environment where touch operations are possible, you can move the PDF data forward or backward, or zoom in or out by touching the screen. If touch operations are not possible, the first page of the PDF data will be displayed for the specified number of seconds.

[0156] Figure 26 shows an example of how a PDF file is displayed when "Display as PDF file" is selected.

[0157] When a landscape PDF file is displayed on a landscape screen, only the first page is displayed, as shown in Figure 26(a)(1). When a landscape PDF file is displayed on a portrait screen, the pages are displayed vertically, as shown in Figure 26(a)(2). When a portrait PDF file is displayed on a landscape screen, only the first page is displayed, as shown in Figure 26(b)(3). When a portrait PDF file is displayed on a portrait screen, the pages are displayed vertically, as shown in Figure 26(b)(4).

[0158] In this manner, the creation of broadcast content in steps S12 to S19 is completed.

[0159] (Signage broadcast) Next, the created broadcast content is broadcast on signage (steps S20 to S22).

[0160] As shown in FIG. 27(a), when the "PLAY" button on the title screen of the application is clicked, the signage starts broadcasting (step S20).

[0161] As shown in Figure 27(b), the created program is broadcast on the screen size set when the program was created. The cursor on the screen is automatically hidden after a predetermined time, for example, 5 seconds. However, if a Web-PDF is displayed, the cursor remains visible and is not hidden.

[0162] If there are no programs being broadcast, the display will be as shown in FIG. 27(c).

[0163] In desktop mode, an alert message is displayed as shown on the left side of Figure 27(c). The user can select to wait for broadcast or cancel broadcast. If wait for broadcast is selected, the program will remain on standby until broadcast begins. If cancel broadcast is selected, the program will no longer be broadcast on this user's information processing terminal.

[0164] In the signage mode, as shown on the right side of FIG. 27(c), the desktop is displayed in full black screen, and the desktop including the toolbar is not displayed.

[0165] To stop the signage broadcast, the signage screen is made active (foreground) and the [ESC] key is pressed, and the signage broadcast is stopped (step S22).

[0166] If it is difficult to determine whether the screen is in the active state, click on the screen to make it active (foreground), and then press the [ESC] key to stop the signage broadcast (step S22).

[0167] If a broadcast program has already been created, the application is started and the title screen of the application shown in Fig. 5 is displayed (step S11), and then signage broadcasting can start (step S24). When the "PLAY" button on the title screen is clicked (step S25), signage broadcasting is performed according to steps S20 to S22.

[0168] (OPTIONS explanation) The setting of the optional functions will be explained with reference to FIG.

[0169] When the application is launched, click the "OPTIONS" button on the application launch screen, as shown in Figure 28(a). An option setting screen, as shown in Figure 28(b), will appear, allowing you to set optional functions for the application. The various optional functions are described below.

[0170] (Operation mode) This function sets the application's operating mode. Applications have two operating modes: "Signage mode" and "Desktop mode." Select the operating mode depending on the application.

[0171] In signage mode, the broadcasting terminal functions as a digital signage player to broadcast content onto the screen.

[0172] In the desktop mode, this application runs as one of the desktop applications.

[0173] The default value for this feature is "Signage Mode".

[0174] (restart and shutdown) This function restarts or shuts down the broadcasting terminal or information processing terminal at a preset time. This can only be set when the operating mode is signage mode.

[0175] The default value for this feature is "Do not restart or shut down" and the time is "0:00".

[0176] (Automatic broadcast when application starts) This function automatically starts scheduled broadcasts when the application is launched.

[0177] The default value for this feature is "Do not start broadcasting."

[0178] (Maximum number of screens) This function sets the maximum number of screens that can be set for one program. It can be set in the range of 1 to 20.

[0179] The default value for this feature is "5".

[0180] (Cache deletion when the program starts airing) This function allows you to select whether to delete the cache when a program starts airing (ON) or not (OFF).

[0181] If you select "Delete Cache" (On), the cache will be deleted when broadcasting begins, and then the latest content will be acquired. By deleting the cache, you can prevent previously cached content from being broadcast if content acquisition fails.

[0182] If the cache is not deleted (off), the cache is maintained and the content will be broadcast using the cached content even if content acquisition fails. If you do not want to display previously cached content when the latest content cannot be obtained, turn this setting on.

[0183] The default value for this feature is "off."

[0184] (Broadcasting will be stopped if the latest content cannot be obtained during broadcasting) This function allows you to select whether to stop broadcasting (ON) or not (OFF) if the latest content cannot be obtained during broadcasting.

[0185] If Stop Broadcasting (On) is selected, if the folder cannot be accessed during broadcasting or an internal error occurs, or if content cannot be obtained, broadcasting will stop for each screen and a black screen with an error message will be displayed.

[0186] If broadcasting is not stopped (OFF), broadcasting will not be stopped and the current broadcasting state will be maintained even if the content cannot be acquired.

[0187] If you want to check on the display screen whether a folder can be accessed or if you want to check the cause of an error, turn this setting on.

[0188] The default value for this feature is "off."

[0189] (Preparation for the program broadcast) This function sets the preparation time for copying the program contents before the program change.

[0190] When a broadcast program switches at a set time, if the file size of the content of the next program is large, it may take a long time to copy the program contents, which may result in a problem where the program does not switch smoothly. To prevent this problem from occurring, it is necessary to copy the contents before the program switches. This function copies the next program before the set time (number of seconds).

[0191] The default value for this feature is 30 seconds.

[0192] (Screen background) This function allows you to set the background color and transparency of the top, bottom, left, and right margins that appear when content that does not match the screen size is displayed.

[0193] The default values for this function are "Background color: black" and "Transparency: 0%".

[0194] (Displays the mouseover menu) This function allows you to set whether or not to display a mouse-over menu containing file names and other information when you move the mouse cursor over the screen during broadcasting in desktop mode.

[0195] The default value for this feature is "Show."

[0196] (Protecting the screen during broadcast) This function allows you to set whether or not to protect the screen during broadcasting.

[0205] The content display system is the same as the content display system of the first embodiment, except that the terminals of the content display system are connected to each other via a local area network (LAN) 100 rather than the Internet.

[0206] [Third embodiment] A content display system according to a third embodiment of the present invention will be described with reference to FIG.

[0207] In the content display system according to this embodiment, as in the content display systems according to the first and second embodiments, predetermined content can be displayed on the projector screen of a display terminal or the display screen of an information processing terminal.

[0208] In addition, the content display system of this embodiment allows a user to operate the display terminal or information processing terminal and add content that the user wishes to broadcast to the content display system from the display terminal or information processing terminal.

[0209] In the content display systems according to the first and second embodiments, in order to change (add, delete) the content to be broadcast or displayed, it was necessary to operate the content management terminal and change (add, delete) the files in the linked folder. When the operator of the broadcast terminal or the user of the information processing terminal wanted to change (add, delete) the content, they had to contact the operator of the content management terminal and have him or her operate it.

[0210] In the content display system of this embodiment, the operator of the broadcast terminal or the user of the information processing terminal can easily change (add) content by using the content display interface.

[0211] A specific example of content display in this embodiment is shown in Fig. 30(a). On a screen 202 of a display screen 200, the contents of files stored in a linked folder 210 on the screen 202 are displayed.

[0212] 30(a) to 30(c), it is assumed that the display of files in linked folder 210 is set to display the highest file in ascending order of file name. Therefore, the content displayed on screen 202 is the content of the highest file in ascending order of file name in linked folder 210. In FIG. 30(a), file P and file Q are stored in linked folder 210, so the content "P" of file P, which is the highest file in ascending order of file name among the stored files, is displayed on screen 202 of display screen 200 of the information processing terminal.

[0213] On the other hand, as shown in FIG. 30(a), on the left side of the desktop of the screen 202 of the display screen 200 of the information processing terminal, file K of content "K", file L of content "L", and file M of content "M" are displayed.

[0214] In this state, if the user of the information processing terminal wishes to add content "M" to the content display system, he or she performs the operations shown in FIGS. 30(a) to 30(c).

[0215] First, as shown in FIG. 30(a), file M of content "M" on the desktop is selected, and then, as shown in FIG. 30(b), the selected file M is dragged and dropped onto the screen 202. A detection means in the control unit of the information processing terminal detects whether or not the file has been dropped onto the screen 202. When this detection means detects that the file has been dropped onto the screen 202, the dropped file M is stored in the linked folder 210 on the screen 202. As a result, file M is stored in the linked folder 210 in addition to files P and Q.

[0216] As a result, file M is the highest of the stored files in ascending order of file name, and as shown in FIG. 30(c), the screen 202 displays the content "M" of file M in linked folder 210'.

[0217] This drag and drop is a file copy operation, so the file M in the content "M" on the desktop on the left side of the screen 202 remains unchanged.

[0218] During this operation, when the mouse cursor is moved to the screen to be dropped, the four sides of the display area of the screen may be highlighted to make it clear which screen is to be dropped.

[0219] Furthermore, until file M is stored in the linked folder 210 on the screen 202, a display indicating that registration processing is in progress, such as an icon showing an open folder, may be displayed in the upper left corner of the screen to let the user of the information processing terminal know that a registration instruction is being executed. Furthermore, to ensure that the user of the information processing terminal knows that registration processing has been performed, even if the registration processing is completed in a short time, the message "Registration processing in progress" may be displayed for a certain period of time, such as one second or more.

[0220] As described above, according to this embodiment, files (contents) can be added to linked folders through intuitive operations using the content display interface.

[0221] Furthermore, if multiple screens are displayed on the display screen, the user of the information processing terminal can freely select the linked folder to which the content is to be changed (added) by dropping a file onto any of the multiple screens.

[0222] In the above description, a file is added to a linked folder by dragging a selected file and dropping it onto the screen, but the display of files in the linked folder is based on the link folder's settings, such as ascending order of file name. This embodiment is not limited to this. For example, a file dragged and dropped onto the screen may be automatically flagged so that it is displayed preferentially regardless of the link folder settings. This allows the operator of the broadcast terminal or the user of the information processing terminal to use the content display interface not only to add content but also to change the content display.

[0223] [Modified embodiment] The present invention is not limited to the above-described embodiment, and various modifications are possible. Furthermore, the notations, expressions, aspects, etc. in the above-described embodiment are merely examples, and the present invention is not limited to these. [Explanation of symbols]
