The present technology may also allow for the inclusion of assets, such as interactive objects, within an electronic book and also for conversions of electronic books rendered according to a first electronic book standard into one or more electronic books according to different electronic book standards.

BACKGROUND OF THE DISCLOSURE

[0002] Current methods for generating electronic books from digital source content may produce undesirably formatted electronic books. For example, digital source content such as a document stored in a word processing program file, when converted into an electronic book according to an electronic book standard such as ePub, results in the generation of an electronic book that does not retain the native format of the digital source content. That is, a view of the electronic book when displayed on a display device may not resemble a view of the digital source content when the digital source content is rendered by an appropriate program (e.g., a program designed to display the content). These errors may arise from discrepancies in conversion of the digital source content according to the electronic book standard. Also, conversion between different electronic book standards remains problematic. SUMMARY OF THE DISCLOSURE

[0023] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosure. It will be apparent, however, to one skilled in the art, that the disclosure may be practiced without these specific details. In other instances, structures and devices are shown at block diagram form only in order to avoid obscuring the disclosure.

[0024] Generally speaking, the present technology is directed to generating electronic books according to various electronic book standards. More specifically, the present technology may convert documents in non-electronic book formats into electronic books. These source documents are hereinafter referred to as "digital source documents." For example, the present technology may convert image files, XML files, portable document files (PDF), and word processing files, Adobe InDesign™, and Quark™ into electronic books according to one or more electronic book standards. While the above-described file types have been provided for explicating exemplary document formats that may be converted into electronic books by the present technology, one of ordinary skill in the art will appreciate that many other non-electronic book format files may likewise be utilized in accordance with the present disclosure.

[0025] Broadly described, the present technology may convert the digital source content into one or more electronic books in such a way that the native format of the digital source content is preserved. Each of the electronic books may include a particular electronic book standard. Exemplary, but non-limiting examples of electronic book standards (also referred to as a book type) include electronic publication (ePub) versions, Kindle™ Format 8 (KF8), iBooks™, along with other electronic book standards that would be known to one of ordinary skill in the art with the present disclosure before them. [0026] In some applications, the present technology may parse the digital source content and extract assets therefrom. Assets may include text, images, frames, and other objects that are commonly utilized in digital document files. Additionally, the layout of the pages of the content may also be determined and/or extracted. It will be understood that the layout may include the positioning of assets within a page of the digital source content. Additionally, it will be further understood that the term "page" may be understood to include not only a typical page format or layout as would be understood relative to a physical book page, but may also include different subsets, segments, or sections of content from a document. Additionally, in some instances the term "page" may be understood relative to a visual representation of an electronic book that is being rendered. For example, if the electronic book was generated in a flowable layout/format, a "page" may include the viewable section of the document that is currently being rendered and displayed. As the electronic book is scrolled through, the "page" or view of the document changes. Moreover, it is noteworthy that the view that is rendered may not necessarily resemble the standard page format of a book. Stated otherwise, a view may include several sections of different pages (which in this instance may in fact refer to the physical pages of a book) of a book. Alternatively, the view may include a continuous flowing page with dynamically changing content.

[0027] Layout data or other metadata about the file (e.g., versioning information, creation/modification dates, author information, etc.) may also be stored in a storage media such as a database.

[0028] The present technology may automatically determine a suitable electronic book standard that is compatible with the digital source content, along with identifying conflicts between the digital source content and one or more electronic book standards. If conflicts are determined, the present technology may communicate conflict messages to an end user that inform the user of the conflict. In other instances, the present technology may automatically adjust attributes of digital source content assets to ensure that they are compatible with the electronic book standard. For example, an image extracted from the digital source content may have a size that is unacceptably large for a particular electronic book standard. The image may be automatically resized to comply with the requirements of the electronic book standard.

[0029] The present technology may render an editable view of the electronic book within an editing user interface. End users may view, insert, delete, or otherwise modify the electronic book via the editing user interface. The editing interface may include a plurality of tools that allow the electronic book to be modified. During conversion between digital source content and electronic book, views may be generated of the electronic book that allows end users to visualize the conversion process. Thus, when an end user makes a modification to the electronic book, a view of the book (or even of a page) may be rendered such that the end user can visualize the modification.

[0030] Additionally, editors may insert, modify, and/or remove rich content from an electronic book. Examples of rich content include, interactive objects such as pop-up windows, navigation menus, table of contents, bibliographies, videos, audio files, three dimensional simulations, animations, links, quizzes, tests, puzzles, social media feeds, micro-blogging content, learning management systems functionalities, multilingual translations, choose your own adventure applications, dictionaries, telephonic or other communicative interfaces, slideshows, along with any other rich features that would be known to one of ordinary skill in the art.

[0031] In some instances, the present technology may generate electronic books by converting between electronic book standards. That is, a first electronic book generated according to a first electronic book standard may be converted by the present technology into a second electronic book that is generated according to a second electronic book standard. Automatic detection and correction may also be implemented in these scenarios.

[0032] These and other advantages of the present technology will be described in greater detail with reference to the collective Figures 1-12.

[0033] FIG. 1 illustrates an exemplary system 100 for practicing aspects of the present technology. The system 100 may include a conversion system 105 that may be implemented in a cloud-based computing environment. A cloud-based computing environment is a resource that typically combines the computational power of a large grouping of processors and/or that combines the storage capacity of a large grouping of computer memories or storage devices. For example, systems that provide a cloud resource may be utilized exclusively by their owners; or such systems may be accessible to outside users who deploy applications within the computing infrastructure to obtain the benefit of large computational or storage resources.

[0034] The cloud may be formed, for example, by a network of web servers, with each web server (or at least a plurality thereof) providing processor and/or storage resources. These servers may manage workloads provided by multiple users (e.g., cloud resource customers or other users). Typically, each user places workload demands upon the cloud that vary in real-time, sometimes dramatically. The nature and extent of these variations typically depend on the type of business associated with the user.

[0035] In other embodiments, the conversion system 105 may include a distributed group of computing devices such as web servers that do not share computing resources or workload. Additionally, the conversion system 105 may include a single computing system that has been provisioned with a plurality of programs that each produces instances of event data.

[0036] End users may access and interact with the conversion system 105 via the client device 110 via a web-based interface, as will be discussed in greater detail infra. The conversion system 105 may communicatively couple with a client device 110 via a network connection 115. The network connection 115 may include any one of a number of private and public communications mediums such as the Internet.

[0037] Additionally, the conversion system 105 may obtain assets or other content such as images, videos, games, quizzes, and so forth, from one or more third party content sources, such as third party content source 120. In some embodiments, the conversion system 105 may also publish or transmit electronic books to various third party distributors or publishers, such as a publisher 125. It will be understood that in some instances, the electronic books generated by the conversion system 105 may be exported to, or stored in a storage media such as a content repository.

[0038] The conversion system 105 may be generally described as a mechanism for converting files that are not in an electronic book format (e.g., ePub) into electronic books, according to an electronic book standard.

Additionally, the system 105 may provide web-based interfaces that allow end users to edit the content of an electronic book and/or or convert an electronic book from a first electronic book standard into another electronic book according to another electronic book standard. The system 105 is provided with a conversion application 200 that will be described in greater detail with reference to FIG. 2.

[0039] FIG. 2 illustrates a conversion application, hereinafter referred to as application 200. The application 200 may be generally described as being configured to obtain digital source content. The digital source content may be arranged in a native format, where the native format determines how the digital source content is displayed on a user interface. Additionally, the application 200 may be further configured to determine characteristics from the digital source content, where the characteristics at least defining a layout of the digital source content in the native format. Also, the application 200 may be further configured to render the determined content into an electronic book according to an electronic book standard, based upon the characteristics such that a generated format of the electronic book substantially corresponds to the native format of the digital source content.

[0040] According to some embodiment, the application 200 may generally include a user interface module 205, an input module 210, a parsing module 215, a rendering engine 220, a storage module 225, an editing module 230, and a re- rendering module 235. It is noteworthy that the application 200 may include additional modules, engines, or components, and still fall within the scope of the present technology. As used herein, the term "module" may also refer to any of an application-specific integrated circuit ("ASIC"), an electronic circuit, a processor (shared, dedicated, or group) that executes one or more software or firmware programs, a combinational logic circuit, and/or other suitable components that provide the described functionality. In other embodiments, individual modules of the application 200 may include separately configured web servers. Also, the application 200 may be provisioned with a cloud.

[0041] Generally described, the application 200 allows end users to input digital source content, manage the imported content, convert the digital source content into an electronic book according to an electronic book standard, and validate the conversion.

[0042] An end user may interact with the application 200 via a graphical user interface that is provisioned as a web-based interface. The web-based interface(s) may be generated by the user interface module 205. It will be understood that the user interface module 205 may generate a plurality of different graphical user interfaces that allow end users (e.g., content authors, editors, artisans, etc.) to access, view, edit, or otherwise interact with digital source content and electronic books generated according to various standards. Examples of graphical user interfaces that are generated by the user interface module 205 are provided in FIGS. 3H-10, which will all be described in greater detail infra.

[0043] End users may upload digital source content to the application 200 via a user interface. In some instances, end users may import files such as image files (e.g., Joint Photographic Experts Group (JPEG), Tagged Image File Format (TIFF), and so forth) where the pages of a document are individual images, Adobe™ InDesign Extensible Markup Language (XML) files, Portable Document Files (PDF), various word processing document files (e.g., text, rich text format, Word™, etc.), and other electronic document file formats that would be known to one of ordinary skill in the art.

[0044] The digital source content may be understood has having a native format. The native format of the digital source content refers to a visual representation of the content that is produced when a view of the digital source content is rendered. It is noteworthy, native format not only refers to the visual representation of the content, but also the structure of the data included in the digital source content files that determines the layout of assets or other content included in the digital source content files. For example, a native format for a PDF document may include a view of a page of the PDF document that is generate by a PDF viewing program. The present technology may preserve the visual appearance of the digital source content when it is converted into an electronic book. In other embodiments, end users may be allowed to edit the visual appearance of the electronic book such that the generated format of the electronic book is similar to the native format for the digital source content, but may include differences such as embellishments or modifications.

[0045] Regardless of the methodology for providing digital source content to the application, once the digital source content has been received by the application 200, the input module 210 obtains the digital source content gathered from input received via one or more user interfaces. The term "obtain" may be understood to include receive, gather, locate, download, pull, or other similar actions. It will be understood that in some instances the input module 210 may receive digital source content via another method than via a user interface, such as uploading via file transfer protocol (FTP).

[0046] The digital source content received by the input module 210 may be provided to the parsing module 215 that determines characteristics from the digital source content. The term "determine" may include evaluate, parse, extract, examine, and so forth. The characteristics of the digital source content may include at least defining a layout of the digital source content in a native format. That is, the parsing module 215 may examine the digital source content to determine the content/assets/objects included in the digital source content, such as text, images, headers, footers, and so forth. Not only does the parsing module 215 determine the assets, but the parsing module 215 may also determine attributes of the assets. For example, an asset such as an image may have attributes such as size, contrast, transparency, and so forth. In addition, the parsing module 215 may also determine the layout of the digital source content as well. More specifically, the parsing module 215 may determine the position assets on a page of a document with reference to a two viable coordinate system (e.g. Cartesian) that defines vertical and horizontal placement of the assets relative to the dimensions of the page.

[0047] In some embodiments, the parsing module 215 may also gather metadata associated not only with the digital source content itself (e.g., ISBN, description, subject codes, price, publication, date, language, etc.), but also metadata associated with individual assets included on each page of the digital source content.

[0048] Once the characteristics for the digital source content have been determined by the parsing module 215, at least a portion of the characteristics may be stored in a storage media by way of the storage module 225. [0049] Once the parsing module 215 has parsed the digital source content, the rendering engine 220 may be executed to convert the extracted content obtained from the digital source content into an electronic book according to an electronic book standard.

[0050] In some instances the end user may select the type of electronic book that they would like to be rendered. In other instances the rendering engine 220 may automatically determine the type of electronic book that is generated by comparing the extracted information obtained from the digital source content to one or more electronic book standards. More specifically, in some instances the characteristics of the digital source content are compared to an electronic book standard, while in additional embodiments, attributes of assets may be compared to the electronic book standard. The electronic book standard that most closely corresponds to the characteristics or attributes of the digital source content may be selected (e.g., the standard having the fewest number of conflicts relative to the assets of the determined content).

[0051 ] Once one or more electronic book standards have been selected, the rendering engine 220 may generate a publication shell that includes all the files and layout information necessary to assemble an electronic book. For example, the rendering engine 220 may create a XML (or XHTML) file that references the locations of assets within the electronic book. The XML file may contain all of the characteristics and asset attributes for the electronic book. In other embodiments, a cascading style sheet (CSS) is created from the publication shell. In some instances, the CSS may include the layout and design for the electronic book. Additional, device-specific files may be obtained or generated that utilized the aforementioned files to render a view of the electronic book on a display device. These device-specific files may include proprietary or specifically tailored files that are readable by a particular type of display device. [0052] Next, the rendering engine 220 may render a view of at least a portion of the electronic book that is displayed via a user interface. As mentioned previously, the generated format of the electronic book may substantially correspond to the native format of the digital source content, such that when views of the electronic book are generated they substantially correspond to view of the digital source content. That is, the rendering engine 220 may maintain consistency between the visual appearance of the digital source content and the electronic book.

[0053] According to other embodiments, the editing module 230 may be executed to receive edits from end users that manipulate the visual appearance or other characteristics of the electronic book. In some instances, the editing module 230 may cooperate with the user interface module 205 to generate editing interfaces that include tools that allow end users to modify an electronic book. More specifically, the rendering engine 220 may render a view of a selected page of an electronic book which is displayed via an editing interface such as shown in FIGS. 3A-3H. As a page (or an asset within a page) is modified, the rendering module 230 may continually generate views of the electronic document such that end users may visually inspect their changes. That is, modifications may be viewed in near real time as the electronic book is modified.

[0054] End users may utilize the tools to modify the page of the electronic book, or individual assets within the page. End users may insert, modify, or delete assets within a page. Non-limiting examples of some contemplated assets include pop-up windows, images, text, and word definitions. Other assets may include a panel-by-panel viewer (e.g., for comic books and other panel-based books) including a function for jumping to a specific frame. Additional assets may include navigation menus, scrollable with thumbnails, links, hyperlinks, along with "style-switching" that allows the end user to change the

appearance/layout of an electronic book in accordance with user preferences. [0055] Other types of assets may include animations (e.g., touch-based and auto-play) along with "reveals" where the reader lifts a cover/flap on the page, such as with physical board books.

[0056] Other assets such as audio (also combined/incorporated into popups and panels, "talking photos" that speak a caption) and cross- promotion/purchasing of songs. Additionally, video assets, which may be combined /incorporated into popups and panels, 3D images and simulated 3D images, which may be interactive (e.g., reacts to touch-based events) or automatically displayed, are also contemplated. Touch-based events like tapping to hear audio/video played and interactive 3D widgets.

[0057] Assets may also include surveying or educational applications. For example, self-check quizzes (where answers are revealed on click), test quizzes (correct/incorrect notice displayed upon selection), final quizzes where a reader can fill out text and email to an instructor or communicated to a Learning Management System (LMS), flash cards that utilize random/ordered terms or definitions.

[0058] Gaming assets may also be included such as crossword puzzles and Sudoku, including a method of sending a "recovery code" to oneself to restore the puzzle to a previous state. Collaborative crossword puzzles with a friend or communication of invitations challenging other readers to participate, integrated social media feeds specific to the subject matter of the book (with options of filtering by classmate and/or school), integration with micro-blogging services to share parts of an electronic book, crowd-source writing, where multiple authors collaborate on an electronic book in real time (also contemplating readers that read in real time. In these instances, the electronic book may be "locked" for editing to readers, but not to "authors."

[0059] Other features may include multilingual translation that may be facilitated by a menu item that toggles to transform a book from one language into another (or a section). The electronic book may also include a "choose your own adventure" feature (e.g., interactive fiction), where the electronic book presents a reader with a series of options/choices in the story and based on their choice, they jump to another part of the book (multiple story threads based on user choice).

[0060] The electronic book may also include a built-in dictionary to replace or enhance an existing dictionary system, enable auto-location of terms in the book and underline those contained in the database.

[0061] The electronic book may also include specific pages that are printable in a book for accompanying activities (e.g. something a child needs to print out and cut/glue according to instructions or a paper plane book), a photo frame feature that is initiated by turning on a switch that changes the device into digital photo frame and displays all the images in the book in random/sequential order.

[0062] Other contemplated features include content obfuscation, where contents of a book may only become visible/unscrambled when a password is entered either for the whole book or on a page-by-page basis. Finger painting and/or coloring, where a reader may use a finger as a brush to fill color in of a coloring page. Books may also comprise drag and drop jigsaw puzzles where readers may drag pieces from a pile into place to complete the picture, along with direct chat or personal communications media (e.g. telephonic or VOIP features) for support, assistance, or instant discussion of the book/page contents with author or fans.

[0063] It will be understood that in some instances assets may be incorporated in the form of a JavaScript or other similar macro, applet, program, widget, and the like.

[0064] When an asset is inserted into an electronic book, the editing module 230 may review the attributes of the asset to determine if there are any potential conflicts between the asset and the electronic book standard that is utilized to generate the electronic book. If the editing module 230 detects a conflict, the editing module 230 may alert the end user by generating and displaying a conflict message via a user interface. In some instances, the editing module 230 may automatically adjust one or more of the attributes of an asset that has been determined to cause a conflict.

[0065] By way of non-limiting example, if an asset such as a video file is inserted, and the format of the video file cannot be played by the display device that utilizes the electronic book standard, then the user may be prompted to replace the video file with a compatible version. In other embodiments, the editing module 230 may automatically convert the video file into a suitable file format.

[0066] In addition to inserting assets, the editing module 230 may allow end users to modify attributes of individual assets, reposition the assets within a page, or delete the asset entirely.

[0067] After modifications have been made to the electronic book, the rendering module 230 may verify the electronic book files (e.g. the CSS, XML, XHTML, etc.) to ensure that the instructions included in the files follow appropriate semantic conventions, that pages have correct suffixes, titles, tags, and so forth. Additionally, CSS files may be validated via a suitable validator.

[0068] The structure of the final electronic book file may also be verified. For example, the metadata file, file manifest, file spine, file guide, or other portions of the book may be verified. Assets may also be verified individually, such as video files, audio files, and the like.

[0069] In some instances, once an electronic book has been generated, the re- rendering module 235 may be executed to transform an electronic book that was generated according to a first electronic book standard into an electronic book generated according to a second electronic book standard. Advantageously, the re-rendering module 235 may determine characteristics from content of the first electronic book, the characteristics at least defining a layout of the content that defines how the content of the first electronic book is displayed. Once the characteristics have been determined, the re-rendering module 235 may transform the content into the second electronic book according to the second electronic book standard.

[0070] It will be understood that conflicts may arise during the conversion process due to discrepancies between electronic book standards, and therefore, the re-rendering module 235 may be configured to detect these conflicts, provide error messages indicative of the conflicts, and in some instances, automatically resolve the conflict, as was described in greater detail with reference to the editing module.
