 Through the implementation of the above technical solution, the segment download of the e-books of various formats can be implemented on the client side, thereby shortening the download waiting time of the e-book and improving the reading experience.

In order to better describe the embodiments of the present invention, the specific embodiments of the present invention will be described with reference to the accompanying drawings. Ming, Example 1:

 FIG. 1 is a schematic flowchart of a method for publishing an e-book according to Embodiment 1 of the present invention, where the method includes:

 Step 11: Divide the electronic version of the book document into a file description section and a data section containing the specified presentation collection.

 In the step 11, the server first divides the specified electronic version of the book document into a file description section and a data section containing the specified presentation set; where the file description section includes a common file section of the shared class document and A data segment index table; wherein the data segments specifying the presentation set may be divided into one or more as needed.

 In the specific implementation process, the server may first divide the electronic version of the book into a shared class document and a plurality of specified presentation sets according to the organizational structure and document content of the electronic book. The shared class document described herein may be the above-mentioned electronic version of the book document required. Documents, such as e-books according to the Epub specification, the required documents are mimetype, container.xml and content. of; or related book information, such as digital copyright files, cover files and cover images; or books Shared files for each chapter, etc.

 The specified presentation set may specifically be the smallest presentation element of the electronic version of the book document. For example, if the minimum presentation element of the electronic version of the document document is divided by chapter, the specified presentation collection may be a description file of the chapter. And a file composed of a chapter, such as a resource file such as a picture or an audio in a chapter; or the designated presentation set may be formed by combining the minimum presentation elements of the electronic version of the document document, for example, The contents of several chapters are combined to form a specified presentation set.

 After the above division, the server may package the shared class document to generate a common file segment, and package the plurality of specified presentation sets separately to generate a plurality of data segments; wherein the public file segment is included in the file. In the description section.

The data segment index table in the file description section may be used to locate each data segment. In a specific implementation process, there are multiple ways to implement positioning, for example, the start position and length of each data segment may be included. The information is realized by the starting position and the length information; the sequence number and the position information defined by the respective data segments may also be included, and the positioning is realized by the defined serial number and position information. In addition, in a specific implementation process, a file format description section may be further included in the file description section, where the file format description section length is fixed, and is used to locate a common file section and a data section index table, In the implementation process, there are multiple ways to achieve positioning, for example, it can include the starting position and length information of the common file segment, and the starting position and length information of the data segment index table, which is realized by the starting position and length information. Positioning; may also include the sequence number and location information defined by the common file section, and the sequence number and location information defined by the data section index table, and the positioning is implemented by the defined sequence number and location information. Since the length of the above file format description section can be fixed, the client can directly download and then use the file format description section to locate other sections.

 In addition, in the specific implementation process, before executing step 11, the corresponding electronic version of the book document may be produced by the book publisher through the server according to the book content and the e-book format specification according to the book. The e-book format specification here may be an electronic publishing Epub specification, or a text format specification or a PDF format specification that supports a minimum presentation set.

 Step 12: Package the divided file description section and data section to generate a book container file. In this step 12, the server packages the divided file description sections and data sections together to generate a book container file.

 Step 13: Publish the generated book container file on the e-book reading platform.

 In this step 13, after the book container file is generated, the server can publish the generated book container file on the e-book reading platform for the reader to download and read through the client.

 Through the implementation of the above technical solution, the segmented e-book can be released, and the format downloading of the e-books in various formats can be implemented on the client side, thereby shortening the download waiting time of the e-book and improving the reading experience.

 Further, in the above embodiment 1, if the electronic version of the book document newly adds the book content, the data segment corresponding to the newly added book content is directly added. In this way, for a serialized book, when a new chapter is added, only the corresponding data section needs to be added, and the reader only needs to download the corresponding newly added data section through the client, instead of Download old chapters to save time and traffic.

In addition, in the above Embodiment 1, it is also possible to encrypt the divided one or more data sectors. By encrypting the data segment, the e-book can be billed by chapter, allowing the reader to Try the free chapters first, then pay for the chapters that read the fees, which further enriches the publisher's charging model, and attracts readers through the trial-reading mode, which is more conducive to the promotion of e-book reading business.

 The following is a detailed description of the Epub-compliant e-book publishing process. Before publishing the Epub specification e-book, first make the corresponding electronic version of the book document based on the book content, including the mimetpye file, the META-INF directory file, and the OEBPS directory file. Then, the electronic version of the book document is packaged into a book container file, which is published on the reading platform for the reader to download and read. The specific process is as follows:

 First, the Epub-compliant electronic version of the book document is divided into a shared class document and a plurality of specified presentation sets according to the content. In this example, the specified presentation set is divided according to chapters, specifically:

 Shared class documentation includes:

 A, Epub's required documents (such as mimetype, container in META-INF, xml, content.opf and toc.ncx in OEBPS directory, etc.);

 B, book information documents (such as digital copyright files, cover files, cover pictures, etc.) c, chapter shared files (such as CSS files)

 The specified presentation set, that is, the chapter class document includes:

 A, chapter description file

 B, chapter exclusive files (such as chapters, pictures, audio and other resource files)

 Then the server packs all the shared class documents to generate a common file segment. As shown in FIG. 2, the shared class document is packaged in the example. Then, each chapter class document is separately packaged to generate multiple data segments, such as FIG. 3 is a schematic diagram showing the packaging of chapter class documents in the present example. The plurality of data segments store all the contents of the specified chapter, and the contents of the chapters are independent of each other and are stored in separate data sections.

In addition, in this example, the server may also generate a file format description section and a data section index table according to the size of the common file section and the size of the data section. The file format description section has a fixed length for locating the common file section and the data section index table. In this example, the file format description section includes the start position and length information of the common file section. And the start position and length information of the data segment index table, and the positioning is implemented by the start position and length information. The server then packages the file format description section, the common file section, the data section index table, and the plurality of data sections together to generate a book container file, as shown in FIG. 4, which is a schematic diagram of the package of the book container file in the present example. The file format description section, the common file section, and the data section index table may be collectively referred to as a file description section. The server then publishes the generated book container file on the reading platform for the reader to download and read through the client.

 It is worth noting that, in addition to the e-books compatible with the Epub specification mentioned in the above examples, other segments are downloaded, for example, an e-book or a PDF-formatted e-book that can be divided into a text format of a minimum presentation set. This further enhances the versatility of eReader or software by supporting common format specifications such as the Epub specification. Example 2:

 The second embodiment further provides a method for downloading an e-book. As shown in FIG. 5, a schematic flowchart of the method provided in the second embodiment is provided. The method includes:

 Step 51: Download the file description section in the book container file on the e-book reading platform. In this step 51, the reader first downloads a file description section in the book container file on the e-book reading platform through the client; here, the file description section includes a common file section and a data section index of the shared class document. Table section.

 In the specific implementation process, the following download process may be adopted: First, the client downloads a file description section in the book container file on the e-book reading platform, and the file description section includes a file format description section, and the file format The description section can be used to locate the common file section and the data section index table. In a specific implementation process, there are multiple ways to achieve positioning, for example, the location and length information of the common file section can be included, and the data area. The starting position and length information of the segment index table is realized by the starting position and length information; the sequence number and position information defined by the common file segment, and the sequence number and position information defined by the data segment index table may also be included. The positioning is implemented by the defined sequence number and position information. In this embodiment, the file format description section is implemented by starting position and length information.

Then, the client further downloads a common file section including the shared class document according to the start position and length information of the common file section provided by the section according to the file format, and according to the file grid The start position and length information of the data segment index table provided by the section is described, and the data section index table is downloaded.

 It should be noted that, in this step 51, the client may also download the file description section including the common file section of the shared class document and the data section index table part without downloading the file format description section, for example, The client can directly learn the message including the corresponding information of the file description section from the server, and then learn the information of each part in the file description section according to the message, and then download the public file section containing the shared class document from the server. And the file description section of the data section index table section.

 Step 52: Locating the data segment of the specified presentation set according to the data segment index table, and downloading the data segment corresponding to the specified presentation set according to the reading requirement.

 In this step 52, the client then locates the data segment of the specified presentation set according to the data segment index table, and then downloads the data segment corresponding to the specified presentation set according to the reading requirement of the reader.

 Step 53: Generate an electronic version of the book document that satisfies the reading requirement according to the shared presentation document in the downloaded common file section and the specified presentation set in the data section.

 In this step 53, after the client downloads the data segment corresponding to the specified presentation set, the client may follow the shared class document in the public file segment downloaded in step 51 and the data segment of the specified presentation set. The electronic version of the book document that satisfies the reading requirement is restored; and then the client can present the book content to the reader according to the electronic version of the book document.

 Through the implementation of the above technical solution, the segment download of the e-books of various formats can be implemented on the client side, thereby shortening the download waiting time of the e-book and improving the reading experience.

 The following is a detailed description of the segment download process compatible with the Epub specification e-book. First, the client downloads the file description section in the book container file on the reading platform according to the reader's reading request, where the file description section includes the shared class document. a common file section and a data section index table section; then, according to the file description section, the data section is downloaded, and the data section corresponding to the specified presentation set is downloaded; and the shared class document and the specified presentation in the common file section are displayed. The data segment of the collection is restored to generate an electronic version of the book document compatible with the Epub specification; the client then presents the book content to the reader according to the generated electronic version of the book document.

In this example, the client may also first download the file format description section, and complete the subsequent download by using the file format description section. Specifically, the client may first download the file format description area. a segment, and then locating the common file segment according to the file format description section, for example, the common file segment can be located according to the start address and length information of the common file segment provided by the file format description section, and read from Downloading a corresponding public file segment on the platform; and then positioning the data segment index table according to the file format description section, for example, the starting address and length of the data segment index table provided by the segment may be described according to the file format. Information is used to locate and download the corresponding data segment index table from the reading platform.

 It is worth noting that the client can also download the file description section containing the shared file section and the file description section of the data section index table section without downloading the file format description section. For example, the client can directly access the server. Obtaining a message including the corresponding information of the file description section, and then learning the information of each part in the file description section according to the message, and then downloading the common file section and the data section index including the shared class document from the reading platform. The file description section of the table section.

 The client then locates the data segment of each specified presentation set according to the data segment index table, for example, according to the starting address and length information of the data segment provided by the data segment index table, and downloads the corresponding information from the reading platform. Specifies the data section of the collection.

 After downloading the public file section and the corresponding data section of the specified presentation set, the client can parse the downloaded public file section and restore the shared class document that generates the Epub specification e-book, as shown in FIG. A schematic diagram of the parsing of the common file section in the instance; parsing the downloaded data section of the specified presentation set, and restoring the specified presentation set of the Epub specification e-book, which is a chapter-type document in this example, as shown in FIG. 7 Schematic diagram of the parsing of the data segment.

 Then, the client restores and generates an electronic version of the book document that satisfies the reading requirement according to the parsed shared class document and the specified presentation set; and then presents the book content to the reader according to the generated electronic version of the book document to satisfy the reader's reading. demand.

 It is worth noting that, in addition to the e-books compatible with the Epub specification mentioned in the above examples, other e-books or e-books in a PDF format that express the minimum text format of the collection. This further enhances the versatility of eReader or software by supporting common format specifications such as the Epub specification.

For a specific application example, as shown in FIG. 8 is a schematic diagram of signaling interaction of the e-book download and reading according to the second embodiment, where: When the reader first reads a chapter of the e-book, the client first downloads the file description section of the e-book, and then uses the file description section to locate the data section of the specified presentation set, and from the reading platform (ie, the server) The data segment of the specified presentation set required for downloading. Since the data segments are relatively independent, the presentation of the data segment content does not depend on other data segments. If the reader needs to read the content of the segmented e-book, it is not necessary to download the entire book, and only need to download the Mth. The data section where the chapter is located, and then the content of the book is presented to the reader by the client. The specific process is as follows: 0-1. The reader first requests the client to read the Mth chapter.

 0-2. The client requests the server to download the file description section.

 0-3, the server returns the file description section.

 0-4. The client requests the server to download the data segment m,.

 0-5, the server returns the data segment m, content.

 0- 6. The client presents the contents of the Mth chapter to the reader.

 As the reader continues to read the subsequent chapters, there is no longer a need to download the file description section. The specific process is:

 1-1. The reader initiates a request to read the Nth chapter to the client.

 1- 2, the client requests the server to download the data segment n,.

 1-3. The server returns the data segment n, the content.

 1-4. The client presents the content of the Nth chapter to the reader.

 As can be seen from the above application examples, for the reader, compared with the entire e-book, each data segment is relatively small, and the download time is short, so that the reading experience can be greatly improved, and at the same time, it can be read while downloading. Further improving the reading experience; for the book publisher, only need to follow the corresponding e-book format specification to make the electronic version of the book document, which can be packaged and released by using the method described in the embodiment of the present invention, thereby realizing each The format specification downloads the segmentation of the e-book, thereby shortening the download waiting time of the e-book and improving the reading experience.
