Hereinafter, embodiments related to a control method that can be implemented in the terminal configured as above will be described with reference to the accompanying drawings. The following embodiments can be used alone or in combination with each other. In addition, the embodiments described below may be used in combination with the above-described user interface (UI).

The present invention provides a method for adding digital content to an electronic book.

The e-book is also referred to as a digital book or an e-book, and is composed of electronic files so that it can be taken out and read at any time in a portable small mobile terminal. Unlike a paper book, the e-book can quickly search for information, directly modify the information, or change the content to the latest contents, and can include not only text but also multimedia information such as sound or image. In addition, the e-book is not a simple electronic document (for example, a Word file, a PDF file, a text file, etc.) but a book constructed so that digital rights management (DRM) is added to prevent illegal copy and unauthorized distribution. In addition, there is an advantage that it is possible to carry over hundreds of electronic books according to the memory capacity of the mobile terminal.

The e-book is advantageous in that it is cheaper than a paper book in terms of the reader, saves time through online purchase, can be purchased separately, and is portable. In addition, publishing companies have the advantage that they can save production costs and printing expenses such as printing and bookbinding, and are easy to update.

However, there are disadvantages to such e-books, one of which is that they can not have a unique distinctiveness from other books, such as a special edition of a paper book. In other words, a paper book is a tool for reading his content, and because it is worth collecting, users buy and hold books. For example, there are many requests for a limited edition of a special edition of a paper book after receiving an autograph of the author after purchasing it, or by adding a special comment or photograph of the author or another ending. However, e-books are equipped with digital rights management (DRM) function to prevent illegal circulation and copying, but they do not satisfy the desire of users who want to hold special books.

A program or hardware for reproducing the e-book is referred to as an 'e-book reader' or an 'electronic reader'.

The e-book reader can play back all types of information (e. G., Text, sound, images, Internet link information, movies, notes, highlights, bookmarks, etc.) contained in the e-book. In addition, the e-book reader may not reproduce only a specific type of information or vice versa. As described above, it is possible to set a playback mode (for example, a text mode, a sound mode, an image mode, a text & sound dual mode, etc.) to control the output of a specific format of information, It can be described that the electronic book is displayed or reproduced according to the format of the electronic book.

The user can execute an e-book reader and then select and play the desired e-book. In order to select the e-book, the user selects 'menu call → select e-book retrieval menu → select folder where e-book is stored → display e-book list in selected folder → select desired e-book from e-book list' . When the user selects a desired electronic book, the controller 180 loads the selected electronic book in the memory 160 and displays the selected electronic book on the screen of the electronic book reader.

Hereinafter, the functions that can be performed during playback of the electronic book will be described with reference to the accompanying drawings.

3 is a flowchart illustrating an electronic book control method of a mobile terminal according to the present invention.

As shown, arbitrary electronic book data (e.g., original data) is stored in the mobile terminal (S101), and data (for example, digital content to be added) to be added to the electronic book is stored in an arbitrary specific medium (S105).

For example, the specific medium may be an electronic coating, or may be an external memory having an arbitrary shape. The specific media may be wirelessly connected to the mobile terminal to transmit the digital content to the mobile terminal, or may be connected to the mobile terminal in a wired manner. Accordingly, the mobile terminal can add the received digital content to the arbitrary e-book.

Here, the same specific code (for example, a specific code related to copyright) previously designated in the electronic book and the specific medium is stored (S102, S106). The specific code may be stored separately, or may be mixed with electronic book data or mixed with digital contents. The specific code is different from digital rights management (DRM) information. Therefore, the electronic book stores original data and digital rights management (DRM) information and a specific code related thereto.

If the user purchases the e-book and downloads it to the mobile terminal (or the electronic book reader) (S103). When it is desired to add the digital content stored in the specific medium to the electronic book, the mobile terminal compares the specific code stored in the electronic book with the specific code stored in the specific medium (S104).

For example, the additional operation of the digital content may be performed by selecting a corresponding menu from the menu list, or automatically when the specific medium is connected to the mobile terminal.

If the specific code stored in the electronic book is identical to the specific code stored in the specific medium as a result of comparing the specific code, the digital rights management (DRM) information set in the electronic book is released (S107). As described above, the digital rights management (DRM) information set in the electronic book is released, and the electronic book original data can be edited.

Accordingly, the controller 180 of the mobile terminal adds the digital contents stored in the specific medium to the electronic book. That is, the data of the electronic book is updated (S108). For example, the digital content may be a photograph composed of a photographer, a comment composed of a voice or text of a signed author, or a content composed of other endings. In addition to the illustrated digital content, digital content composed of other formats (e.g., video, music) and content may be added.

After completing the addition of the digital content stored in the specific medium to the electronic book, the mobile terminal resets or restores the digital rights management (DRM) information of the electronic book (S109).

4 is an exemplary diagram illustrating a method for connecting a specific medium to a mobile terminal according to the present invention.

As described above, the specific medium 211 can be connected to the mobile terminal 100 in a wireless manner or in a wired manner. That is, the specific medium 211 can establish a communication path with the mobile terminal in a wireless or wired manner.

The wireless system may automatically connect the specific medium to the mobile terminal when the specific medium is within a predetermined distance set in the mobile terminal by using a short-range wireless communication method such as infrared ray, RFID, or Bluetooth. That is, the mobile terminal can automatically detect or recognize a specific medium within a predetermined distance, and set a communication path.

When the user executes a sub menu for connecting a specific medium in a menu list (not shown), the control unit 180 can detect the connection of the specific medium and set the communication path.

Here, the mobile terminal may include a dedicated input unit (not shown) for recognizing the specific medium or inputting the specific medium by photographing the specific medium using the camera 121 according to the type of the specific medium, When it is connected to the dedicated input unit, it can recognize the specific medium or detect the input of the specific medium within a predetermined distance set by using the short-range communication module 114.

On the other hand, the wired system can configure a communication port (not shown) for connecting the specific medium in a shape corresponding to a communication port of the specific medium, such as a USB port or an external memory slot.

Accordingly, when the specific medium is connected to the communication port of the mobile terminal, the controller 180 of the mobile terminal can establish a communication path with the specific medium. For reference, the specific medium may be formed in a coating shape, an external memory shape, a card shape, a sticker shape, or other various shapes.

As described above, it is assumed that a specific medium 211 storing a specific digital content is communicatively connected to a mobile terminal in which an electronic book is stored. That is, the mobile terminal detects that the specific medium is connected. When the specific medium is connected as described above, the control unit 180 detects which e-book is associated with the specific medium.

In order to detect an electronic book associated with the specific medium, the control unit 180 detects a specific code stored in the specific medium. The specific code is a code related to the digital rights management (DRM) information of the electronic book. That is, the specific code is a code serving as a key for releasing or restoring the digital rights management (DRM) information. Therefore, it is obvious that the same code as the specific code must be included in the electronic book.

The controller 180 detects a specific code included in the electronic book and a specific code stored in the specific medium, and then compares the specific code with the same code. According to the comparison result, if the specific code stored in the specific medium and the specific code included in the electronic book are not the same, the controller 180 does not perform any operation. Or a message informing that there is no e-book associated with the specific medium.

If the specific code stored in the specific medium and the specific code included in the electronic book are the same according to the comparison result, the controller 180 can release the digital rights management (DRM) information set in the electronic book.

Also, when the digital rights management (DRM) information of the electronic book is released as described above, the control unit 180 may output a guidance message asking the user whether to release the digital rights management (DRM) information. When the user makes an affirmative response to the guidance message, the digital rights management (DRM) information can be released.

6 is an exemplary diagram showing a method of adding specific digital contents to an electronic book according to the present invention.

As described above, the controller 180 releases the digital rights management (DRM) information set in the electronic book 210, reads the specific digital content stored in the specific medium, and stores the read digital content in the memory 160. [ As described above, the digital rights management (DRM) information set in the electronic book is released, and the electronic book original data can be edited.

Accordingly, the controller 180 reads the specific digital content stored in the memory 160 and automatically adds the read digital content to the electronic book 210. Here, the specific digital content may be added to a specific portion (e.g., first portion, middle portion, or end portion) of the electronic book original data. That is, the specific digital content may include information related to a location to be added.

The specific digital content may be configured in a format different from the original data of the electronic book. For example, in a multimedia format. That is, the specific digital content may be composed of a photograph or an autograph, a voice or a comment of a writer, or a music or a moving picture of the artist.

When the specific digital content stored in the specific medium is added to the electronic book as described above, the control unit 180 of the mobile terminal restores or re-sets digital rights management (DRM) information of the electronic book.

FIG. 7 is a diagram illustrating a process of adding specific digital content to an electronic book according to the present invention.

As shown in the figure, it is assumed that the user is using the e-book contents stored in the mobile terminal (311).

The controller 180 detects whether communication between the mobile terminal and the specific medium is established. Or connects the communication between the mobile terminal and the specific medium according to a user's operation (312). When the communication is established as described above, the controller 180 can download the specific code and the specific digital content from the specific medium.

Alternatively, the control unit 180 may scan a specific image (e.g., an image of an electronic painting) included in the specific medium. At this time, the specific image and the digital content may be configured in an image form. Therefore, the mobile terminal can receive the digital contents included in the specific image of the specific medium without connecting the communication with the specific medium. The specific image may be scanned using a camera 121 configured in the mobile terminal, or may be provided with a dedicated scanning device (not shown). Here, the mobile terminal incorporates a specific code configured in the form of an image and a program for decoding digital contents as described above, and the program can use any known program.

After the specific code is downloaded from the specific medium or the specific medium is scanned to detect the specific code, the controller 180 reads the specific code detected by the downloading or scanning and the specific code included in the electronic book (316).

As a result of the comparison, if the specific codes are different from each other, it is notified that there is no e-book associated with the specific medium and the updating of the e-book is stopped (316).

However, if it is determined that the specific codes are identical to each other, the digital rights management (DRM) information set in the electronic book is released, and the electronic book is updated using specific digital contents detected by downloading or scanning the specific medium (314).

The particular digital content may be added at the beginning, the end or the middle of the electronic book. Also, the specific digital content may be data in which a part of the electronic book is modified or added. For example, the original ebook does not have an image, but the particular digital content may be data in which a new image is additionally updated on a particular page.

As described above, the controller 180 may add the specific digital content stored in the specific medium to the electronic book or update the electronic book using the digital content (314). When the addition or update of the digital content is completed as described above, the control unit 180 restores the digital rights management (DRM) information that has been released. The user can then use the updated e-book content (315).
