Description

Electronic book system using wireless internet {An electronic book system using wireless internet}

The present invention relates to an e-book system using wireless internet, wherein a user connects to a server computer via wireless internet, converts various e-book files stored in the server computer into a predetermined format, and converts them into a text format to the user's mobile terminal. The present invention relates to an e-book system that outputs an e-book file to a user by providing a voice conversion engine installed in a web server.

Since the early history of human history, when humans began to write records using letters, symbols, and figures, books have been created using a variety of materials to store information. In the early days, books were made by writing letters on clay or writing on reeds or leather. After paper was invented in China, books were made by writing on paper. After metal invented, books were printed on paper. The method of making a book by printing on paper is still the most widely used. However, a paper book requires a lot of storage space and a short preservation period, making it inconvenient to store and use a large amount of information. Therefore, in recent years, a method of storing information in a microfilm to reduce storage space and extending a preservation period has been used, but it is not suitable for the digital age in which all information is converted to digital.

As Internet and digital technologies have evolved, books have started to be produced in digital form, and digital books are e-books. E-books are expected to be used the most in the digital age because they do not cost publication costs, do not require materials such as paper and ink, do not have inventory concerns, and do not cost distribution costs. Although e-books currently occupy a small portion of the current book market, the number of published e-books is increasing and the size of the e-book market is growing day by day.

In addition to the advantages described above, e-books can be produced by distributing the revised parts separately even when publishing the revised version, which improves the inconvenience of having to buy a new book when the revised edition is published. The feature is that the information can be provided to the reader.

To use an e-book, install an e-book program on your computer, run the program whenever you want to read the book, and view the e-book. E-book programs can be installed not only on desktop computers and laptops, but also on hand held personal computers (HPCs) and Palm PCs, and can be installed and used on portable devices such as PDAs (Personal Digital Assistants) and e-book readers. However, in an age of frequent movements such as these days, a system for viewing e-books while moving is needed. You can read books on the go with your laptop, HPC, Palm PC or PDA, but you won't be able to use them if you don't have the files you want. In addition, since e-books have different file formats for each company, a new e-book viewer program must be installed to view e-books with different file formats. On a computer with a large memory capacity, such as a desktop computer, many programs can be installed to use the e-book service, but on a personal memory device such as HPC, the program installation is restricted. Since it is impossible, the use of e-books through personal portable terminals is rarely achieved at present.

Therefore, in this age of frequent movement of people and high traffic volume, the amount of information generated is so great that dozens of books are published and poured out every morning. There is a need for a new type of e-book system that can alleviate the inconvenience and read various kinds of e-books made of various newly created file formats while moving.

Unlike the above-described configuration, it is an example of a case where a text-to-speech 120 is connected to a web server. The server 100 converts e-books, electronic documents, or electronic news information in the database 200 into a form of voice using the voice conversion engine 120 to connect to the server through the wireless Internet. To provide. 5 is a configuration example in which e-book information is transmitted by connecting a personal portable terminal such as a PDA or HPC to the mobile communication terminal 10 by wire, and FIG. 6 illustrates a short-range communication protocol (bluetooth) for the personal portable terminal 20. The configuration example of receiving e-book information from the mobile communication terminal 10 is shown.

Wireless Internet is a system in which a mobile communication terminal and a web server computer communicate with each other through a wireless base station. Wired Internet connects computers and web servers and requires a gateway to communicate with both, even over wireless. Computers, gateways, and gateways and web servers can send and receive data using the Hypertext Markup Language (html) language, which is based on the http (hypertext transfer protocol) protocol, but wireless Internet does not support WAP (Wireless). A mobile communication terminal communicates with a gateway via a wireless base station based on a wireless internet protocol such as an application protocol, a mobile explore, or a WSP. Once the communication with the mobile communication terminal and the gateway is made through the wireless Internet, the gateway connects the mobile communication terminal and the web server computer by transmitting and receiving data in accordance with the web server computer and the http protocol.

In order for the mobile communication terminal to start the wireless Internet, communication with the gateway must first be made. The gateway cannot communicate with all wireless Internet protocols, and only a few limited wireless Internet protocols communicate with mobile terminals. In order for the gateway and the web server computer to communicate, an interface must be installed on the web server computer to transmit and receive information from the gateway.

In order to use the wireless Internet as a mobile communication terminal, an internet browser or a mobile communication terminal with an internet access program must be purchased or an internet browser or an internet access program must be installed in the mobile communication terminal. When an Internet browser or an internet access program installed in a mobile communication terminal is executed, it is connected to a gateway via a wireless base station and accesses a portal site, which is a gateway for internet travel. The portal site is the gateway to the Internet. It is the site that is accessed when you first run the Internet. When you are connected to the portal site, you can go to the next site.

When accessing a website that provides an e-book service through a portal site, the user selects a desired e-book by searching the menu of the site. When the user selects an e-book to read, the web server converts the file format of the e-book file into a file format that can be viewed as text characters in the display window of the mobile communication terminal, and uses mobile technology for streaming. It downloads e-books page by page to the display window of the terminal so that the user can view the contents.

Streaming technology involves breaking a file into tiny pieces, downloading the files in small pieces, running the small pieces in sequence, deleting the executed file, and executing another piece. Technology. With streaming technology, even large files can be viewed as if they were watching a video, and the time required to run them can be relayed in real time, and because the files are not stored in memory, they do not affect the memory. It is used a lot.

In recent years, in order to greatly expand the memory of a mobile communication terminal such as a mobile phone or a PDA, a mobile communication terminal may be embedded with a very large memory or an auxiliary memory such as a flash memory or a storage memory. There is a lot of work to expand the memory. Therefore, when the flash memory or the storage memory which is an auxiliary memory is installed in the mobile communication terminal or when the memory capacity of the mobile communication terminal is large enough, the e-book file is downloaded to the auxiliary memory of the mobile communication terminal or the memory of the mobile communication terminal. You can view it and run it. In this case, since the e-book file is stored in the memory, the user can view the contents by executing the e-book file stored in the memory, and whenever the user wants to see the e-book, the contents are executed by executing the e-book file stored in the memory. Can be.

When the user accesses the server 20 through the wireless Internet using the mobile communication terminal 10 and then clicks a menu list and selects an e-book through the provided screen, the mobile communication terminal 10 sends a signal. The server receives the signal, and retrieves the file from the database 200.

In a conventional e-book system, various e-book formats exist, and when a user acquires and receives this information, an e-book browser program suitable for the format is required. To overcome this, US-based VVault Inc. has developed a file format transform engine called vftault engine that converts all file formats into one new file format. . Normally all programs can optionally specify a file format when saving. Most programs can save not only their own file formats, but also text files. Accordingly, in the present invention, the FFT engine is connected to a server computer to access a memory area in which a file is stored, search for a stored file, temporarily retrieve a file, convert the file into a text file format, and save the file format in a text file format. To convert the file back to a specific file format.

In order to avoid the trouble of converting the e-book file format, it is possible to install a specific e-book viewer program that executes only a specific e-book file in the mobile communication terminal. In this case, the e-book file is downloaded directly from the web server computer. You can view the contents of an e-book file, but you can only see e-books in a specific file format.

On the other hand, if the TTS engine 120 is installed in the server computer 100, the file can be converted into voice and output. In this case, the e-book file is input to the TTS engine 120 and the TTS engine converts the text characters included in the e-book file into voice and outputs the voice to the mobile communication terminal 10.

Currently, devices used as mobile communication terminals include mobile phones, some types of PDAs, and Palm PCs. Most personal handheld devices, including PDAs and HPCs, do not have their own built-in communication devices, so they cannot directly connect to the wireless Internet to view or send or receive files. Thus, these personal handheld terminals should be connected to a mobile communication terminal capable of communicating to establish a wireless Internet. In this case, the e-book file can be viewed by page using streaming technology, and the e-book file can be stored in a personal mobile terminal to view the book.

The personal mobile terminal and the mobile communication terminal may be directly connected by wire, but when using a short distance wireless communication system, Bluetooth (blue tooth), the personal mobile terminal and the mobile communication terminal may be wirelessly used. Since it does not need to be connected to and has an advantage that it can be easily accessed, a user with a personal mobile terminal can easily access the wireless Internet and receive an e-book service by accessing a mobile communication terminal using Bluetooth.

The conventional web server that provides the e-book service is similar in function, configuration, and use to the server of the website providing the newspaper article or the website server of the newspaper. The biggest difference is only the names of e-books, digital newspapers and digital magazines. Therefore, when using the e-book system using the wireless Internet used in the present invention by accessing the website of the newspaper, the website providing the newspaper article and the website providing the contents of the magazine to the mobile communication terminal the contents in the form of text characters It can be used in the form of viewing a digital file including an e-book file by outputting it to a display window of a mobile communication terminal or executing a specific program embedded in the mobile communication terminal.

7 is a configuration example in which both the FFT engine 110 and the TTS engine 120 are mounted on the server 100. A system for converting an arbitrary digital file including an e-book file in the database 200 into a text using the FFT engine 110 and then outputting a voice to a mobile communication terminal through the wireless Internet using the TTS engine 120. It is also possible to easily apply and use.

The e-book system according to the present invention can help a mobile communication terminal user to easily access various types of e-newspapers and e-magazines, which are not only digital information but also names, as well as various types of e-book files. It will be used as a system to help modern people who have strong desires to share a lot of information regardless of place.

As described above, since the e-book system according to the present invention can show all kinds of e-book files, it is not necessary to install all kinds of document editing programs in the mobile terminal, thereby reducing the memory capacity of the mobile terminal, The contents of the e-book can be output as a voice, so that the contents of the e-book can be understood while listening to the contents of the book without fatigue. In addition, the present invention outputs the contents by accessing the data such as newspapers and magazines stored as digital files, such as e-book files to the wireless Internet using a mobile communication terminal or outputting e-books by voice using a TTS engine As it can be used as a system to make it possible, it is possible to supply various types of digital data in an easier way to people with high mobility.
