The content DB 250 is a standard digital textbook content DB 252 produced by a content creator and provided to a general user in the same manner, and a customized digital textbook content DB edited to each user's level and preference by individual users. (254).

The standard digital textbook content DB 252 and the customized digital textbook content DB 254 are content information included in each standard digital textbook and the customized digital textbook, and a plurality of layer information configured on each page and linked to each layer Unit content, metadata, and the like. The meta data includes attribute information such as position information, size information, content format, format, etc. for displaying the unit content on the corresponding layer.

In particular, the personalized digital textbook content DB 254 is a personal storage space allocated to each user, and stores new unit content when metadata and unit content edited by each user are new.

Therefore, if there is a reproduction of a specific page for any digital textbook, the digital textbook providing unit 240 is assigned to the layer information corresponding to the specific page and to each layer from the standard digital textbook content DB 252 or the customized digital textbook content DB 254. Based on the linked unit content and the metadata, the unit content is disposed on the layer based on the attribute information included in the metadata, and the unit content is superimposed between the layers to be displayed on the screen.

A digital textbook for this purpose may be specifically implemented as shown in FIG. 3. That is, the digital textbook is composed of a plurality of layers (layers 10, 20, 30, and 40) according to content types such as text, images, and videos, and each layer (10, 20, 30, 40) according to a predetermined unit. It includes unit content which divided content content, and metadata of a unit content.

For example, if a digital textbook is composed of several pages, each page is composed of a plurality of layers according to the content type, and each layer has a certain area, an image file unit, or a memo input by a user as shown in FIG. 4A. One or more unit contents (pd-000001, tx-001001, ph-00001, vd-00001, etc.) classified according to a predetermined unit, such as (highlight display, input of additional content, etc.) are linked. Therefore, when displaying the page, a plurality of layers including the unit content are overlaid.

The plurality of layers 10, 20, 30, and 40 may be divided into a grid layer 10, a text layer 20, a photo or image layer 30, an application layer 40, and the like. Can be.

The grid layer 10 is also referred to as a first layer, which is the bottom layer, and functions as a reference coordinate grid that can synchronize the playback positions of other contents. In addition, since the grid layer 10 is composed of data in PDF format, it is also called a PDF layer and performs a function of PDF rendering.

The text layer 20 is also called a second layer and includes a renderer and data. Data refers to text data stored in a format such as XML, HTML, etc., and a renderer calls text data to be combined with a template that is pre-authored.

The photo or image layer 30 is also called a third layer and includes data about an image such as a picture or a video. The photo or image layer 30 may be recycled by importing an original file and utilizing text data.

In addition, the text layer 20, the photo or image layer 30 may be stacked in plural numbers depending on the content of the data or additionally updated.

In addition, the text layer 20, the photo or image layer 30 includes only link information such as caption, option, and matching data as metadata, and the original file (unit content) By storing separately, when displaying the layers 20 and 30, the original file (unit content) matching the metadata may be loaded.

The meta data includes unit content name 252a, content type 252b, location information 252c, data format 252d, and the like, as shown in FIG. 4B. The location information 252c includes layer information.

As such, the configuration of the digital textbook according to the embodiment of the present invention provides for individual editing by unit content in more detail for each layer. In particular, the subscribers can easily manage the data of the original digital textbooks while subscribing to the service by changing and editing only the metadata by inserting or deleting the unit contents in a desired position. It guarantees autonomy of editing for one user.

5 is a diagram illustrating a configuration of a user terminal.

The user terminal 100 includes a communication interface 110, an inputter 120, a display 130, a data processor 140, a content provider 150, and a storage 160.

The communication interface 110 interfaces data transmission and reception with the digital textbook management server 200 of FIG. 1 through a communication network. That is, when a user requests a digital textbook through the input unit 120, the digital textbook management server (200 of FIG. 1) is requested, and the requested digital textbook is received from the digital textbook management server (200 of FIG. 1). 140).

The input unit 120 requests a desired digital textbook and receives a user's manipulation signal such as a click or drag for accessing, playing, and editing the requested digital textbook. The input unit 120 may include a keypad, a touch pad, and the like provided in the terminal.

The display unit 130 provides an edit screen and a playback screen under the control of the content provider 150.

The data processor 140 encodes the data of the digital textbook received through the communication interface 110 and transmits the data to the content provider 150.

The storage unit 160 stores a viewer program for playing or displaying a digital textbook, and stores an editing program 162 for editing a digital textbook.

In particular, the storage unit 160 according to an embodiment of the present invention may store and package the edit information, that is, metadata of the digital textbook edited by the content provider 150, in the edit information DB 164.

In addition, the storage 160 may store the unit content of the digital textbook, and in particular, when inserting a file possessed by a user, it may store it as the unit content.

The content providing unit 150 provides a reproduction and editing function for the digital textbook received through the data processing unit 140.

The digital textbook reproducing unit 152 executes the viewer program to reproduce the digital textbook, and the digital textbook editing unit 154 executes the editing program to edit the digital textbook.

When editing, the digital textbook editing unit 154 of the content providing unit 150 selectively receives a format and an editing method of a screen desired by the user, and uses unit tools of a digital textbook using an editing tool for the selected screen format. Edit by inserting or deleting new unit content. In this case, the editing means not editing the unit content itself, but changing and editing the metadata of the unit content.

The new unit content may be information obtained through an internet search, or may include an image file, a text file, a video file, etc. obtained by an individual user.

As shown in FIG. 9, the format of the screen provides a kind of editing style in which regions for inserting text, an image, a video, and the like are designated.

The above editing method is a method of bringing the unit content to be edited into the edit screen, selecting a region to be edited by the user on a screen displaying a digital textbook, and selecting unit content matching the selected position, A method of selecting and applying unit content names from a textual table in which information (meta data) is stored, or selecting a corresponding unit content based on a directory file of a digital textbook may be used.

In addition, the content provider 150 delivers the metadata edited through the digital textbook editing unit 154 or a customized digital textbook including the metadata to an external digital textbook management server through the communication interface 110 to upload. And set whether to publish, share, and sell customized digital textbooks uploaded.

Therefore, when the user terminal 100 edits a digital textbook provided by the digital textbook management server, the user terminal 100 edits the content of the digital textbook for the convenience of the user and uses the unit content of the digital textbook, but actually edits the digital textbook. It provides a specific structure for editing by processing the digital textbook metadata without processing the digital textbook itself.

Next, a method of reproducing and editing a digital textbook based on the configuration of the user terminal and the digital textbook management server described above will be described with reference to the illustrated screen.

6 is a flowchart illustrating a method for individually editing a digital textbook in a user terminal according to an embodiment of the present invention, and FIG. 7 is a detailed view of some steps of FIG. 6.

First, a process of editing a digital textbook will be described with reference to FIG. 6.

The user terminal executes a pre-stored editing program and is authenticated through a user login (S100). This certification process can be viewed as a process for managing and providing customized digital textbooks generated by multiple users on a digital textbook management server.

Therefore, the user login process (S100) may be performed before editing as shown, but is not limited to the temporal order thereof, and may be performed when transmitting the edited information to the digital textbook management server, or the user in the interim process. Depending on the specific task, it can be performed at any time when authentication is required.

Subsequently, when the user terminal is authenticated through a user login or executes an editing program, a screen to be edited is displayed on the screen, and a selection of a format of the screen that the user wants to edit, ie, an editing form, is input from the guide screen. (S110). It also accepts a selection of digital textbooks to edit.

The format of the screen may have various formats as shown in FIG. 9.

The edit screen 90 includes a menu bar 91 for displaying and guiding an operation menu for editing on the screen, a login menu 91a for displaying and guiding a login execution menu for user authentication, as shown in FIG. Since the format of the screen for editing the digital textbook is set, the editing window 92 for inserting and editing desired unit contents in the corresponding areas 92a and 92b is provided.

In this case, the edit window 92 shows three box areas into which an image or a video can be inserted, and a screen format into which text or a background image can be inserted into a background other than the box area, but is not limited thereto. Various configurations can be made according to the number, size, and position ratio of the regions.

Referring back to FIG. 6, the user terminal displays a format of the selected screen, displays a guide to select an editing method menu to be used for the format of the displayed screen, and receives a selection of an editing method therefrom (S120, S130).

The editing method here refers to a method of bringing up unit content to be edited into the editing screen. The editing method is to select the area to be edited by the user on the screen displaying the digital textbook graphically and to select the unit content that matches the selected position, and select the unit content name from the textual table in which the information on the unit content is stored. It may include a method of applying, a method of selecting and applying the unit content based on the directory file of the digital textbook. This method will be described in detail with reference to FIGS. 10 to 15.

Next, the user terminal edits the digital textbook according to the selected editing method and generates a user-specific digital textbook having a layer structure based on the edited information (S140).

To this end, the user terminal simultaneously displays the target screen to be edited and the edit screen on one screen as shown in FIG. 7 (S142). The target screen to be edited is a screen displaying a target digital textbook to be edited through a viewer program, and the edit screen includes a screen providing a format of the screen as shown in FIG. 9.

Thereafter, the user terminal displays the unit content of the corresponding digital textbook on the target screen to be edited according to the editing method selected by the user, and edits the unit content displayed on the target screen to be edited using an editing tool on the edit screen (S144). , S146).

For example, the selected unit content can be edited by inserting it into a desired area by using an editing tool such as moving or copying in the edit screen. Alternatively, new new unit content obtained from outside can be imported and inserted into the desired area for editing.

When unit content or new unit content is inserted through the editing program, the user terminal generates new metadata by reflecting the position information of the inserted unit content or new unit content in the metadata, and based on the generated metadata Create your own custom digital textbooks.

Thereafter, as illustrated in FIG. 6, the user terminal divides and stores the metadata of the edited unit content for each digital textbook in the storage unit in the terminal (S150). When the edited unit content is new unit content, not only the metadata of the new unit content but also the new unit content itself are stored in the storage unit.

Thereafter, the user terminal may transmit a user-specific digital textbook generated by including the edited metadata to the network-based digital textbook management server and request an upload thereof (S160).

In this case, the user terminal may be provided with an additional service according to whether the user is set by setting whether to open, share, or sell the customized digital textbook to other users. In particular, in the case of a shared service, a user can designate a specific group and a specific user to share only with a desired user.

For example, FIG. 10 is a diagram illustrating a method of selecting and applying unit content corresponding to a selected position when a user selects an area to be edited on a screen on which a digital textbook is displayed graphically in an editing method.

In the screen 90-1 according to an example, an edit target screen window 94 displaying a digital textbook to be edited on one screen and an edit window 92 providing a format of the screen to be edited are simultaneously displayed. .

The editing method through this screen 90-1 is the easiest way for the user to edit since the content of the unit content to be edited is visually displayed when editing the customized digital textbook.

In the content of the digital textbook displayed on the target screen window 94 to be edited, a specific image C1 may be selected or a specific region C2 may be selected. Then, the selected specific image C1 or the specific region C2 is dragged and moved to each of the regions 92a and 92b of the editing window 92. As a result, the customized digital textbook may include the specific image C1 or the dragged image. When the metadata of the specific area C2 is attached and displayed on the screen, unit content matching the attached metadata is displayed.

In this case, dragging means designating and moving on the screen, and the moving may directly move a desired content through a mouse or a touch input or perform a command through a keyboard input device. The content dragged to the respective areas 92a and 92b of the editing window 92 is stored and displayed as the content of the customized digital textbook.

As another example, FIG. 11 illustrates a method of selecting and applying unit content names from a text type table in which metadata is stored in an editing method.

In the screen 90-2 according to another example, a metadata table including information on unit content is displayed on the screen window 94 to be edited, and the form (i.e., format of the screen) to be edited is displayed on the edit window 92. ) Is displayed.

The meta data table shows information on the unit content name, content type, etc. in text form, which is different from the screen 92-1 of FIG. 10.

The user selects arbitrary unit contents (MA-IM-000004, MA-PD-000005: S) from the metadata table, and inserts the selected unit contents (S) into the edit window 92 by operating a command such as dragging. do. Then, a layer for reflecting the unit content may be set in the customized digital textbook and displayed accordingly.

As another example, FIG. 12 illustrates a method of selecting and applying corresponding unit content based on a directory file of a digital textbook in an editing method.

In the screen 90-3 according to another example, the contents of the directory file of the data file stored in the terminal are displayed on the screen window 94 to be edited, and the edit window 92 is the format of the screen of the form to be edited. This illustrates what is displayed.

In the drawing, for convenience, it is indicated as "00 00 00 000", but is actually indicated by a file name and a file format.

Of course, not only the directory but also each file is displayed in the form of an icon, and the selected icon is selected and moved to the edit window 92 so that the contents of the selected file are applied to the respective areas 92a and 92b of the edit window 92. can do.

As another example, FIG. 13 is a view illustrating a method of loading new unit content to be edited from the Internet, an external terminal, or a user terminal, except for a digital textbook provided from a digital textbook management server.

On the screen 91-4 according to FIG. 13, an editing target screen window 94 connected to the Internet or a specific data server and a terminal is displayed on one side, and the editing provided on the screen format of a form to be edited on the other side. Window 92 is displayed.

For this purpose, an address window (not shown) or a search box 52 for inputting an access address to access a specific data server is displayed on the target screen window 94 to be edited, and a desired keyword is entered in the search box 52 to search. The result is displayed in the target screen window 94 to be edited.

In this case, the search target may be information through the Internet, information stored in a member terminal, and the user may be content stored in his or her own storage space in the digital textbook management server.

For example, when searching for the photovoltaic Great King, the search result information on the photogenic Great King is displayed on the target screen window 94 to be edited, and the user selects an arbitrary unit area S1 and a map image from the displayed content. When moving to the respective areas 92a and 92b of the editing window 92, the contents corresponding to the selected unit area S1 and the map image are reflected and displayed in each area.

As another example, FIG. 14 illustrates an example of directly editing a digital textbook in an editing window.

That is, when the digital textbook provided from the server is called up and displayed in the edit window 91, the specific screen C1 or the specific image C2 is selected on the displayed screen, the operation menu or the hot key is operated, or a predetermined time elapses. An editing menu 30a for deleting, saving, searching, and searching for the selected data is displayed. By selecting the edit menu displayed, the specific image C2 may be deleted or replaced with another image or video.

For example, selecting Delete in the menu display 30a deletes the corresponding data in the edit window 92. Selecting Find provides the pre-stored data in the storage and selects and replaces the desired data from the provided data. To be provided.

As another example, FIG. 15 is a diagram schematically illustrating the type of editing for a digital textbook in an editing window.

When the integrated edit menu is selected in the menu bar 91 of the edit screen, various types that can be edited in the screen are collectively displayed, and the user can directly access the desired edit item by selecting the desired edit type from the displayed type.

For example, if 'unit content editing' is selected from various types of editing, the unit content table shown in FIG. 11 is displayed and individual editing can be performed by selecting unit content by a predetermined algorithm. In this case, when the playback or viewer method of the original unit content is edited, the additionally edited metadata is applied to the metadata matching the unit content, and when the unit content itself is edited, the new unit content to be edited is personalized. Store the data in the storage space, generate metadata for the new unit content, and apply the generated metadata to the digital textbook.

8 is a flowchart illustrating a method of selecting a digital textbook in a user terminal according to an exemplary embodiment of the present invention.

First, the user terminal displays a list screen for the digital textbook on the screen (S200). The list of digital textbooks can be provided in real time in cooperation with a network-based digital textbook management server, or updated data can be stored and provided every cycle.

In the digital textbook list screen, the user terminal checks whether there is a selection of a digital textbook from the user (S210).

If there is a selection, the selected digital textbook is displayed (S220). In this case, the name of the selected digital textbook and the user-specified digital textbook, if present, are displayed in a degree that is divided into standard type and customized. If there is no user-specific digital textbook, only the name of the digital textbook can be shown. In some cases, information on the subject name of the digital textbook, the history of viewing the digital textbook, and a brief description of the digital textbook may be displayed together.

Thereafter, when the user terminal requests a reproduction of the standard digital textbook from the user with respect to the digital textbook displayed on the screen, the corresponding standard digital textbook is retrieved and displayed on the screen (S230 and S232).

In addition, when a user terminal inputs a request for reproducing a personalized digital textbook from a user with respect to the digital textbook displayed on the screen, the user terminal may receive and display the requested personalized digital textbook only when approved for user authentication. S240, S242, S244).

In addition, when a user inputs a request for editing a standard digital textbook instead of a reproduction request from the user with respect to the digital textbook displayed on the screen, the editing program is executed and the process of FIG. 6 described above is performed (S250 and S252).

16 is a diagram illustrating a structure for providing a digital textbook according to an embodiment of the present invention.

For reference, FIG. 16 illustrates a type of stored information stored in a user terminal of Hong Gil-dong (user) who has edited a digital textbook for better understanding.

A user who subscribes to the service receives a unique classification code for each user and is allocated a personal storage space.

Accordingly, the personal storage space stores the classification code (XX XX XXX XX) issued along with the user information called Hong Gil-dong, and the information on the customized digital textbook edited by Hong Gil-dong is stored in a layer structure per page.

For example, in the thirteenth page of the second history subject, the edited screen format form 17 and the unit content information 17a and 17b linked to each screen format region are matched and stored.

Therefore, when Hong Gil-dong selects the screen display of a personalized digital textbook individually edited on the user terminal, selects a middle history textbook, and then selects page 13, the content of the individually edited screen format and the unit content linked to each area is displayed. You will see the displayed screen.

17 is a diagram of an embodiment showing a technical method for editing a digital textbook.

As in the previous embodiment, the present invention utilizes a plurality of layer structures to edit digital textbooks. That is, as shown in FIG. 17, the plurality of layer structures are connected to each piece of content data. In addition, the link and the attribute information of the content data are the same as in the above embodiment.

However, features of the layer structure according to the embodiment of FIG. 17 for implementing a more convenient editing structure are as follows.

1) It has a plurality of layer structures, each layer is a virtual layer structure, the size of each layer is the same, the size of the applied coordinates are also the same.

That is, as illustrated in FIG. 17, the sizes of the first layer 11 (called the first layer from the bottom for convenience), the second layer 22, and the Nth layer 99 are all the same. The size of "X" and "Y" is applied to all layers as they are. In other words, if the value of "X" is 100 mm, the value of "X" of all layers is 100 mm.

The coordinates of the first layer 11, the second layer 22, and the Nth layer 99 are the same. As shown in the diagram of FIG. 17, the coordinate scales of all layers (coordinates from 1 to 100 are shown in FIG. 17 as one embodiment in FIG. 17) are the same. The magnitudes between one coordinate scale are the same, and the number of coordinates is the same.

2) Each layer specifies the content property or feature to be linked.

For example, the first layer 11 may be designated to link text content data, the second layer 22 may be designated to link image content data, and the third layer 33 may be designated to link application data. Can be specified. Of course, the first layer 11 must be a text layer, and the second layer 22 is not necessarily an image layer. The first layer 11 may be an image layer.

In other words, even if the order of the properties or features of the content designated for each layer can be changed, the content properties or features are designated for each layer.

3) There may be two or more pieces of data in one layer. Each layer stores only coordinate positions and data storage positions, and stores content data in a separate storage location.

In this case, the separate storage place is a database of the memory unit of the user terminal 100 or the digital textbook management server 200.

Therefore, when editing a digital textbook having a plurality of layers, the editing is performed by specifying the position 5 and size of the content data on the layer and specifying the linked content data.

Therefore, designating the location 5 of the content data in the embodiment of the present invention means designating the location in coordinates. As shown in FIG. 17, in order to designate the content position 5 on the coordinates, the coordinates of four vertices (four vertices of each content position 5 in the drawing are indicated as 1,2,3,4) are designated. I mean. Of course, since the location of the content is generally rectangular, only the positions on the coordinates of vertices 1 and 4 are practically specified.

4) In addition to a plurality of predetermined layers (indicated by “SL” in FIG. 17), an editor may add a layer to create an additional layer (indicated by “AL” in FIG. 17).

For example, you can create additional layers so that content data about "Power Point" or "HWP" programs can be linked. For example, assuming that the predetermined layer SL is four layers (not necessarily four), N layers may be further created. At this time, the attribute of the content data to which the newly created layer is linked may also be designated.

In addition, a memo layer may be added by specifying a memo layer that allows an editor to input new memo information and the like.

5) Content positions present in each layer do not overlap each other.

For example, as shown in FIG. 17, the content data is not present at the position where the content data exists in the first layer 11 and in the second layer 22. And, this function can be an automatic function when editing digital textbooks.

That is, if the coordinate of the vertex 1 of the content location 5 of the first layer 11 is (7,7) and the coordinate of the vertex 4 is (15,80), the (7) on the second layer 22 , 7) so that the content is not located within the coordinates and (15,80) coordinates.

This nesting prevention feature can be executed automatically by a program. At this time, in order not to be applied too strictly, overlapping criteria may be limited such that each content position 5 does not overlap more than 25%. And, the non-overlapping positions mean that the coordinates of each content position 5 do not overlap as a result.

For example, if the "X" coordinate range of the content location 5 of the first layer 11 is from 7 to 15, the "X" coordinate of the content location 5 of the second layer 22 is from 15 or May be located from at least 13.

6) The frequency of content data used in digital textbooks can be counted.

For example, if the unit data 252a " MA-PD-0001 " (252a) "MA-PD-0001" is used three times and is to count these frequencies.

18 is a diagram of an embodiment illustrating a group between members.

When registering, it is possible to distinguish between members who are authorized to edit digital textbooks and those who are not authorized to edit. That is, when a member is a teacher member, digital textbooks can be edited, and student members belonging to the same group as the teacher member can be provided with digital textbooks edited by teacher members of the same group.

19 is a flowchart illustrating a method of executing a digital textbook.

When the program is started in the user terminal and the digital textbook is executed, a login for inputting an ID or the like is performed (S300 to S310).

For this process, the user terminal must access the digital textbook management server 200. In some cases, the digital textbook may be executed in the terminal independently of the user terminal without being connected to the digital textbook management server 200.

When the user accesses the digital textbook management server 200 and logs in, it is determined whether the digital textbook management server 200 is a member capable of editing the digital textbook (S315). The fact that a digital textbook can be edited means that the digital textbook can be edited through various methods described in the above embodiments.

Thereafter, when editing of the digital textbook is selected, the content data to be edited is selected (S320). For example, the content data to be displayed in the digital textbook may be selected using the method described with reference to FIGS. 10 and 16.

Subsequently, when a page of a digital textbook to be displayed by a user or an editor is designated, a layer matching the attribute of the selected content data is selected (S325).

For example, if the property of the selected content data is image data and the image data is located on the second layer in the designated page of the digital textbook, the selected image data is automatically located on the second layer without the editor specifying the layer separately. Will be done.

In addition, when the editor designates the position where the content is displayed in the layer, coordinates of the designated position are generated (S330 and S335).

For example, as shown in the embodiment of FIG. 17, when the location 5 of the content existing in the first layer 11 is designated, the coordinate of the designated content location 5 (the coordinate of vertex 1 is (7,7) Or vertex 4 coordinates (15, 80))) will be automatically generated.

Thereafter, when editing of the selected content data is finished, the storage location layer, the position coordinates, and the like of the content data are stored (S340). In this case, the information may be stored in the personal database of the member who edited the digital textbook.

The digital textbook editing of the present invention suggests a method capable of individual editing, and the edited information may be stored in the member's personal database after the individual editing is completed. Alternatively, the edit information of the digital textbook may be stored in a memory unit of the personal user terminal 100.

In addition, if the member is not allowed to edit the digital textbook, the editing of the digital textbook cannot be executed, and if the digital textbook is edited in the same group, the edited digital textbook is executed to be displayed on the personal user terminal 100. It may be (S350).

Thereafter, when the execution of the digital textbook is terminated, the program is terminated (S345, S355).

The foregoing description is merely illustrative of the present invention, and various modifications may be made by those skilled in the art without departing from the spirit of the present invention. Accordingly, the embodiments disclosed in the specification of the present invention are not intended to limit the present invention. The scope of the present invention should be construed according to the following claims, and all the techniques within the scope of equivalents should be construed as being included in the scope of the present invention.
