In order to better describe the embodiments of the present invention, the specific embodiments of the present invention are now described in conjunction with the accompanying drawings. Embodiment 1:

As shown in Figure 1, it is a schematic flow chart of the method for publishing e-books provided by Embodiment 1 of the present invention, and the method includes:

Step 11: Divide the electronic book document into a file description section and a data section containing a specified display set.

In this step 11, the server first divides the designated electronic version book document into a file description section and a data section containing a specified display set; here, the file description section includes a public file section of a shared document and a A data segment index table; wherein, the data segment specifying the display set can be divided into one or more as required.

In the specific implementation process, the server can first divide the electronic version of the book into shared documents and multiple specified display sets according to the organizational structure and document content of the electronic version of the book. documents, such as e-books according to the Epub specification, the required documents are mimetype, container.xml and content.opf; or related book information, such as digital copyright files, cover files and cover images, etc.; or books Shared files for each chapter, etc.

The specified presentation set may specifically be the minimum presentation element of the electronic version book document, for example, if the minimum presentation element of the electronic version book document is divided by chapter, then the specified presentation set may be the description file of the chapter It is composed of files exclusive to the chapter, such as resource files such as pictures or audio in the chapter; or, the specified display set can also be formed by combining the minimum display elements of the electronic version of the book document, for example, the The contents of several chapters are combined to form a specified presentation set.

After the above-mentioned division, the server can package the shared document to generate a common file segment, and package the multiple specified display sets to generate multiple data segments; wherein, the above-mentioned common file segment is included in the file in the description section.

The data segment index table in the above-mentioned file description segment can be used to locate each data segment. In the specific implementation process, there are many ways to achieve positioning, for example, it can include the starting position and length of each data segment Information, positioning is realized through the starting position and length information; it can also contain the serial number and position information defined by each data segment, and positioning is realized through the defined serial number and position information.

In addition, in the specific implementation process, the file format description section may also be included in the file description section. The file format description section has a fixed length and is used to locate the common file section and the data section index table. In the implementation process, there are many ways to achieve positioning, for example, it can include the starting position and length information of the public file segment, and the starting position and length information of the data segment index table, and realize it through the starting position and length information Locating; it can also include the sequence number and location information defined by the public file segment, and the sequence number and location information defined by the data segment index table, and the location is realized through the defined sequence number and location information. Since the length of the above-mentioned file format description section can be fixed, the client can directly download, and then locate other sections through the file format description section.

In addition, in the specific implementation process, before step 11 is executed, the book publisher can also create the corresponding electronic version of the book document through the server according to the content of the book and the format specification of the electronic book. Here, the e-book format specification may be an electronic publishing Epub specification, or may be a text format specification or a PDF format specification that supports a minimum display set.

Step 12: Pack the divided file description section and data section to generate a book container file.

In step 12, the server packs the divided file description section and data section together to generate a book container file.

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

In 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 readers to download and read through the client.

Through the implementation of the above-mentioned technical solution, it is possible to realize segmented e-book publishing, and implement segmented downloading of e-books in various formats on the client side, thereby shortening the waiting time for downloading e-books and improving reading experience.

In addition, in the first embodiment above, if a new book content is added to the electronic book document, the data section corresponding to the newly added book content is directly added. In this way, for serial books, when new chapters are added, only the corresponding data segments need to be added, and readers only need to download the corresponding newly added data segments through the client. Download older chapters, saving time and traffic.

In addition, in the first embodiment above, one or more divided data segments may also be encrypted. By encrypting the data segment, e-books can be billed by chapters, allowing readers to try the free chapters first, and then pay to download and read the paid chapters, thus further enriching the publisher's charging model. Through the trial reading mode To attract readers, it is more conducive to the promotion of e-book reading business.

The following takes the release process of an Epub-compliant e-book as an example to describe in detail. Before publishing an Epub-compliant e-book, first create a corresponding electronic version of the book file according to the content of the book, including mimetpye files, META-INF directory files, and OEBPS directory files. ; Then package the electronic version of the book document into a book container file, and publish it on the reading platform for readers to download and read. The specific process is as follows:

Firstly, the electronic book documents compatible with the Epub specification are divided into shared documents and multiple specified display sets according to content. In this example, the specified display sets are divided according to chapters. Specifically:

Shared class documentation includes:

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

B. Book information documents (such as digital copyright files, cover files, cover images, etc.)

C. Chapter shared files (such as CSS files)

And the specified display collection, that is, chapter documents include:

A. Chapter description file

B. Chapter exclusive files (such as picture, audio and other resource files in the chapter)

Then the server packages all the shared documents to generate public file sections, as shown in Figure 2, which is a schematic diagram of the packaged shared documents in this example; then packages each chapter document separately to generate multiple data sections, such as FIG. 3 is a schematic diagram of packaging chapter documents in this example. The plurality of data segments store all the contents of the specified chapters, and the contents of each chapter are independent from each other and are stored in independent data segments.

In addition, in this example, the server can also generate the file format description section and the data section index table according to the size of the public file section and the size of the data section. The length of the file format description section is fixed, and it is used to locate the public file section and the data section index table. In this example, the file format description section contains the starting position and length information of the public file section , and the start position and length information of the data segment index table, the location is realized through the start position and length information.

Then the server packs the file format description section, common file section, data section index table, and multiple data sections together to generate a book container file, as shown in Figure 4, which is a schematic diagram of book container file packaging in this example , the file format description section, common file section and data section index table may be collectively referred to as a file description section. Then the server publishes the generated book container file on the reading platform for readers 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, e-books with other format specifications can also be released to the public according to the method described in the above-mentioned embodiment 1 to support segmented downloading by the client. For example, it can support An electronic book in a text format or an electronic book in a PDF format, etc., divided into minimum display sets. In this way, by supporting common format specifications (such as Epub specifications), the versatility of electronic reading devices or software can be further enhanced.

Example 2:

This embodiment 2 also provides a method for downloading e-books, as shown in Figure 5 is a schematic flow chart of the method provided by this embodiment 2, 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, first the reader downloads the file description section in the book container file on the e-book reading platform through the client; here, the file description section includes the public file section and the data section index of the shared document table part.
