{Method for Generating File of Electronic Book and Playing the Same File}

The present invention relates to a method for generating an e-book file displayable in an e-book terminal and a method for reproducing an e-book file generated by such a method, and more particularly, to generate and reproduce an e-book file having a plurality of contents. It is about a method.

Recently, as mobile devices have been widely used and communication technologies have been developed, e-books that can be played on mobile terminals have been widely used. E-books can be downloaded through data communication networks such as Wi-Fi or 3G or wired Internet networks, and can be stored on portable mobile devices, allowing users to easily access e-books regardless of time and space. In addition, inventory management costs are reduced from the point of view of the publishing company, and users can use e-books at a low price. In addition, according to the storage capacity of the e-book terminal can store a large number of e-books at the same time, compared to the conventional paper book is also a great advantage in storage. In addition, multimedia content supported by a computer may be inserted into an e-book, and dynamic content, in which a user may directly control a flow, may be freely implemented.

In the present specification, an electronic book is defined as "a general term for a digital book that can be used as a book by recording information such as a text or an image on an electronic medium", and the type thereof is not limited.

E-book contents are determined by the characteristics of the terminal on which the contents are played. The most common format is EPUB, and Amazon Kind's Kindle format and Apple Inc. There is an iBook format. This format supports traditional content such as text and graphics, which are the most basic elements of e-books, and expands support for multimedia and interactive content. In the electronic book, metadata for storing additional information such as layout, style, cross-reference, etc. of the content data, as well as data on the content itself, functions as a major element of the e-book format.

Support for each unit of content in an e-book—text, graphics, video, and so on—is becoming richer and more sophisticated, but even in e-books, a single fixed table of contents, like a paper book, whose contents are developed according to a single table of contents set by the author. You can only view the contents in sequence or select a specific item from the displayed table of contents.

In general, the table of contents is determined by the author's intention and determines the flow or order in which the reader reads the book. However, in some cases, it may be possible to construct a plurality of content flows even in a book containing the same content. For example, in the case of history-related books, it is possible not only to have a partial table of contents, which is a description of the order of time, but also to develop the contents of the book by organizing the table of contents by subject or person. In the case of specialized books, it is possible to present a table of contents in which a specific content is omitted when the reader is a beginner.

U. S. Patent No. 6,493, 437 discloses a system and method for generating e-book files and converting display screens. However, the patent discloses a method of generating an e-book file that can be displayed in various ways according to a specific font size, display screen size, font type, and the like, and is still silent about a table of contents change or diversification technology.

An option tab 280, a next page movement tab 255, and the like for changing or the like may be displayed.

Next, an e-book file generation method according to the present invention will be described with reference to FIGS. 3 to 6. E-book file generation is performed by the e-book file generation computer 101.

First, in step 310, a source file providing content of an e-book is parsed. This step 310 analyzes the content stored in the source file and performs decomposition and structuring according to its characteristics. As described above, the contents constituting the e-book are text contents, graphic contents, interactive contents, multimedia contents, and other types of contents may exist. An example of the content will be described.

An embodiment of a unit content block, which is a structure corresponding to various contents extracted by parsing a source file, is illustrated in FIG. 5. Each content block 500, 510, 520, 530 includes a unique number, a type, content data, and information on a style in which the content data is actually represented. In the present specification and claims, "unique number" and "unique number information" are regarded and used as the same term meaning information capable of identifying a specific content block or information block.

In the case of using the dedicated authoring tool of the WYSIWYG method, the source file parsing step 310 may be performed by accepting content-related data in the authoring tool program as an input.

After the parsing of the source file, the meta-content block is generated. A table of contents information block 410 and a page information block 420 (see FIG. 4).

The book information block 400 includes the first unique number information, the number information of the associated table of contents information block, and the second unique number information assigned to each associated table of contents information block. The book information block 400 may also include style information.

In the present specification, the first unique number information means identification information for distinguishing a specific e-book file from other e-books, and the second unique number information indicates identification information for distinguishing a table of contents information block from another table of contents information. it means.

Next, the table of contents information block 410 includes second unique number information, number information of page information blocks of pages displayed according to the corresponding table of contents, and third unique number information for identifying each page information block. . The table of contents information block 410 may include style information.

The page information block 420 includes third unique number information, information on the number of unit content blocks displayed on the corresponding page, fourth unique number information for identifying each unit content block, and position information on which the content is displayed. Include. The page information block 420 may further include style information.

When generation of the meta-content block as described above is completed, a hierarchy of the content block is configured in step 330. In this step, the meta-content blocks generated in step 320 are associated with each other to arrange and reflect the unit contents so as to correspond to the respective contents. One example of such a hierarchy is shown in FIG. 6.

In the example of the hierarchical structure shown in FIG. 6, the number of contents information blocks assigned to the e-book file is two, the total number of page information blocks of the displayable page is four, and the total number of unit content blocks displayable is 4 cases.

The first table of contents information block 610 is associated to display the pages of the first page information block 630 to the third page information block 650, and in the second table of contents information block 620, the second page information block ( 640 is associated with the page of the fourth page information block 660 to display the page. This page display difference is determined according to the contents generated and recorded in the meta-content block.

As shown in FIG. 6, the first page information block 630 to the fourth page information block 660 are unit content information blocks included in each page, that is, the first unit content information blocks 670 to the fourth unit. The content information block 685 is associated with each page information block according to a predetermined rule to form a hierarchy of content blocks.

When the hierarchical structure of the content block is completed as described above, the e-book file is generated and stored accordingly (step 340).

The e-book file generated through the above process may be transmitted to the e-book terminal 100 through the communication network 102 or to the e-book terminal through the external storage device 190.

7 shows a flowchart of a method of playing an e-book generated by the present invention, and FIG. 8 shows an example of a screen displayed in the process of playing an e-book.

When playing the e-book generated by the present invention, a menu "Select Table of Contents" is generated as shown in FIG. If the user selects a specific table of contents, the user accesses and checks a table of contents information block corresponding to the selected table of contents (step 710). The "Select a table of contents" menu may display the entire list of contents as shown in FIG. You can also configure the "Select a table of contents" menu button to be visible without displaying the list of contents.

9 shows an example of the configuration of each table of contents displayed in the list of contents of FIG. 8. In this example, the various configurable tables of contents for the eBook "Introduction to Programming Languages" are shown.

If the user selects a specific table of contents, it is determined whether the user reads the contents of the table of contents for the first time (step 720). If it is determined in step 720 that the user has previously read the contents of the table of contents, check the last page read. Access the page information block corresponding to the page (step 740), and if it is determined that the user has not previously read the contents of the table of contents, check the first page (step 730) and then page information corresponding to the first page. Access the block (step 750).

In operation 760, a page capable of displaying the unit contents associated with the accessed page information block on the e-book device in a designated style and attributes at a designated position (coordinate) is generated.
