Here, when the remote control signal for selecting the digital e-book content is received by the IPTV 100 of the user terminal, the user terminal transmits the request signal for the digital e-book content to the information content server 200.

The database 210 holds various categories of digital e-book content. In particular, digital e-book content can be used in domestic / foreign books, novels, religion, social / politics, management / economics, self-development, children, infants, adolescents, family / life / cooking, health / medicine, art / popular culture, travel / hobbies Books, magazines, cartoons, languages, dictionaries, and so on. The classification of the category may correspond to the aforementioned directory for each category. Meanwhile, in order to ensure the reliability and up-to-dateness of the digital e-book contents, the collecting unit 201 of the information content server 200 periodically searches for, collects or updates new digital e-book contents or digital e-book contents to be updated. .

The conversion unit 203 parses the digital e-book content retrieved by the retrieval unit 204 and converts the digital e-book content into a data format suitable for the IPTV 100 attribute. An example of the property of the IPTV 100 includes a display property of the IPTV 100, and the conversion unit 203 parses the digital e-book content and converts the display size according to the display property of the IPTV 100. That is, the display resolution and size set in the digital e-book content itself is converted into a resolution and size suitable for the IPTV 100 screen.

On the other hand, digital e-book content is generally written in a markup language (Markup Language), in particular may be written in XML (Extensible Markup Language). Accordingly, the conversion unit 203 converts the digital e-book content of the markup language into a data format consisting of text and images corresponding to the display attribute of the IPTV 100.

The transmitter 205 provides the data converted by the converter 203 to the user terminal. Accordingly, the set-top box 110 receives the converted data of the electronic book content from the transmission unit 205 and provides the converted data to the IPTV 110 so that the received converted data is displayed on the IPTV 110.

Meanwhile, in the system according to the present invention, the user terminal may store the converted data received from the transmitter 205. The user terminal displays the converted data received from the transmitter 205 on the screen. In particular, when the remote control signal requesting the display of specific digital e-book content is received by the IPTV 100, the received conversion data is displayed on the screen of the IPTV 100 in units of pages.

As a format for displaying the converted data on the screen, the present invention supports the automatic turning mode and the manual turning mode. In particular, in the present invention, the automatic handover mode can be set as the default (Defalult). Accordingly, the IPTV 100 displays the converted data on the screen in units of pages, and automatically turns over the current page to the next page at a predetermined time interval and displays the converted page.

In the present invention, when the IPTV 100 is in the automatic turning mode and automatically converts and displays the converted data in units of pages, the present invention may adjust a time interval for turning pages. To this end, the IPTV 100 may further display a time control to select a time interval for automatically turning the page. Here, the time control is a means for selecting one of several times, such as 30 seconds, 1 minute, 1 minute 30 seconds, as a time interval when the page is automatically flipped, and if a remote control signal for selecting a specific time interval is received in the time control, The IPTV 100 displays the current page by turning the current page to the next page at corresponding time intervals.

Meanwhile, the IPTV 100 may further display a page control for manually turning a page to support a user's request for turning the page. Here, the page control is a means for allowing the user to select a page turn by selecting and operating the remote control. When the remote control signal for requesting a page turn is received according to the selection made through the page control, the IPTV 100 does not display the current page until then. Turn to the next page and display.

As another example, in addition to the method in which the IPTV 100 supports the automatic turning mode and the manual turning mode, in the present invention, the page for selecting either the manual turning of the page or the automatic turning of the page at a predetermined time interval in the conversion data itself. A control may include a time control for selecting a time interval during the automatic handover. This is an implementation example for minimizing the structural change of the IPTV 100.

On the other hand, the information content server 200 or the user terminal according to the present invention can use a TTS (Text To Speech) conversion algorithm. In particular, the conversion unit 203 of the information content server 200 may convert text included in the digital e-book content or the conversion data into voice using a TTS conversion algorithm. The input data of the TTS conversion algorithm in the conversion unit 203 may be data converted according to the attributes of the user terminal in the conversion unit 203 itself, or may be digital e-book content before conversion retrieved by the search unit 204. have. However, the conversion unit 203 may first convert the retrieved digital e-book content according to the attributes of the user terminal, extract text from the result data, and convert the text into voice through a TTS conversion algorithm. Thereafter, the information content server 200 may synchronize the converted voice with another data format of the converted data, that is, an image, and transmit the same to the user terminal.

On the other hand, when the user terminal has a TTS conversion algorithm and the received conversion data includes text, the user terminal, in particular, the IPTV 100 extracts the text from the received conversion data, and converts the extracted text into a TTS conversion program. Convert to voice through. Thereafter, the converted voice may be output in synchronization with another data format of the received converted data, that is, the image.

The following describes an IPTV-based e-book providing procedure based on the system configuration described above.

Collecting digital e-book content (S100).

The information content server classifies the collected digital e-book content by category and stores it in a database (S110). As another example, the information content server may convert the collected digital e-book content according to the IPTV attribute in advance and store it in the database. However, hereinafter, the collected digital e-book content itself will be described as being stored in a database.

If there is an IP connection request from the user terminal (S120), the information content server allows the IP connection connection through authentication (S130). That is, if there is an IP connection connection request from the user terminal, the server first authenticates the user terminal. If the IP connection identification number of the user terminal is valid in the authentication, the IP connection connection to the user terminal is allowed.

Thereafter, the server monitors whether a request for specific digital e-book content is received from a user terminal allowed to access the IP. To this end, the server transmits a metafile of a plurality of digital e-book contents stored in the database to the user terminal in advance. By transmitting the metafile, the IPTV displays various category directories stored in the database based on the metafile including the electronic book name, author name, publication date, publisher and summary of the book. When the remote control signal for selecting one digital e-book content from the displayed directory based on the metafile is received by the IPTV of the user terminal, the server confirms that there is a request for providing the digital e-book content therefrom.

When the information content server receives the request signal of the specific digital e-book content from the user terminal (S140), the information content server retrieves the requested digital e-book content from the database (S150).

Then, the server converts the retrieved digital e-book content based on the IPTV attribute of the user terminal before transmitting the retrieved digital e-book content to the user terminal (S160). In detail, the server parses the retrieved digital e-book content into a resolution and size suitable for the display properties of the IPTV, and also converts it into a data format including text and images displayable on the IPTV. For example, texts and images suitable for the display attribute of an IPTV are extracted from digital e-book contents written in XML, and the extracted text and images are combined to form each page at a resolution and size suitable for the display attributes of the IPTV.

Next, the information content server provides the converted data to the user terminal (S170). As one example, the information content server includes a page control and a time control in the converted data. Here, the page control is for selecting one of manual page turning or automatic page turning at a predetermined time interval, and the time control is for selecting a time interval at the time of automatic turning.

In detail, at the user terminal, the set-top box (STB) receives the converted data from the server, and the set-top box transmits the received converted data to the IPTV. The IPTV outputs the converted data on the screen.

On the other hand, after outputting the converted data on the screen, an operation of turning each page constituting the converted data is performed according to the automatic turning mode or the manual turning mode supported by the IPTV.

The following describes a procedure for outputting the converted data received from the user terminal in various formats.

Referring to FIG. 4, the user terminal receives a metafile including electronic book names, author names, publication dates, publishers, and summary contents of books of various digital electronic book contents (S200).

Then, the directory for each category stored in the server-side database is displayed based on the metafile including the electronic book name, the author name, the publication date, the publisher and the summary of the book (S210).

Subsequently, if receiving a remote control signal for selecting one digital e-book content from the displayed directory based on the metafile (S220), the user terminal transmits a request signal for the corresponding digital e-book content to the information content server. In step S230, the digital e-book content itself, not the converted data thereof, is received.

The user terminal outputs the received converted data. In particular, the IPTV of the user terminal displays the converted data on the screen in units of pages (S240).

When displaying the conversion data on the screen in units of pages as described above, the present invention supports the automatic turning mode and the manual turning mode in turning pages. To support these two modes, the conversion data itself may include the above-described time control or page control itself, or the IPTV may display the conversion data on a page-by-page basis, and then output the two modes through output control. You can also apply.

On the other hand, when operating in the automatic flip mode, the current page is automatically flipped to the next page at predetermined time intervals and displayed on the IPTV screen (S250). And in the auto skip mode, you can select the time interval to automatically skip through the time control.

On the other hand, when operating in the manual flip mode, it monitors whether a remote controller signal for requesting the page turn is received once. If the remote controller signal for turning to the next page is received in the manual turning mode (S260), the current page is turned to the next page and displayed on the IPTV screen (S270).

While the preferred embodiments of the present invention have been described so far, those skilled in the art may implement the present invention in a modified form without departing from the essential characteristics of the present invention.
