The present invention relates to an apparatus and method for implementing browsing of contents provided through DTV. More particularly, the present invention relates to an effective browsing of contents provided through DTV through a user interface markup language for DTV. It relates to an apparatus and a method.

Currently, the DTV broadcasting environment displays video or audio data along with additional data in a format such as Hyper Text Markup Language (HTML). In addition, the way web content is displayed on the DTV screen is described by browsing HTML or XHTML (eXtended HTML) in a modified format.

A number of inventions have been filed or registered for implementing a user interface for browsing contents provided through DTV. For example, Application No. 10-1999-0061181, "Method for converting hypertext markup language for a television-only web browser." In this paper, we suggest parsing HTML documents that are displayed in a web browser according to the TV environment so that tags that cannot be supported by the TV are deleted or modified with other tags.

As another example, in Patent Application No. 10-1999-0025570 'Information Browsing Method of Home Information Terminal', when a link tag appears when parsing an HTML document to facilitate link movement in the HTML document, the number is displayed on the TV screen. You can easily navigate to the link using the number buttons.

However, since the above-described applications of the present invention attempt to fit the TV environment using the existing HTML language, when the tag is deleted or changed, the content of the TV content is deleted or changed, which is not suitable for the presentation of the TV content. There are many limitations in the DTV environment. Accordingly, there is a need for an implementation of a browsing method suitable for a DTV environment, and therefore, markup languages for DTV for a user interface are defined and used.

The present invention has been made to solve the above problems, the object and the technical task of the present invention is to introduce a new tag (tag) or attribute (tag) in the markup language for the user interface suitable for DTV environment The present invention provides a device and method for implementing browsing for effective browsing of contents presented through DTV.

In order to achieve the above object and technical problem, the browsing implementation apparatus disclosed in the present specification includes a browsing type determination unit for determining a browsing type assigned to content presented on a DTV screen from a browsing execution request signal transmitted from a DTV user interface device; A markup language code decoding unit to decode a markup language code of the content with reference to the determined browsing type; And a browsing execution unit that performs browsing by the type of browsing determined by the decrypted language code to achieve the object and technical problem of the present invention.

In addition, in order to achieve the above object and technical problem, the browsing implementation method disclosed in the present specification comprises the steps of: (a) determining the browsing type assigned to the content presented on the DTV screen from the browsing execution signal transmitted from the DTV user interface device; ; (b) decoding a markup language code of the content with reference to the determined browsing type; And (c) executing the browsing according to the type of browsing determined by the decrypted language code to achieve the object and technical problem of the present invention.

For the sake of understanding, the technical spirit provided by the present invention is first presented. First, link and input forms (hereinafter, referred to as "objects") are designated as a group to enable the movement of pointers in units of objects. will be.

Secondly, by dividing the DTV screen, the pointer can be moved for each divided screen so that the user can directly move to a desired place by using the number buttons of the remote controller.

Third, when the content is displayed on the DTV screen, the content is not displayed in whole but in units of pages divided by the content creator.

Fourth, the entire contents of the contents are not shown on the DTV screen, but only the information such as the title is displayed, and the entire contents are displayed when the user wants to.

Hereinafter, in order to clarify the technical spirit of the present invention, the configuration and operation thereof will be described in detail with reference to the accompanying drawings based on the embodiments of the present invention. Although the same reference numerals have been given even in different drawings, it will be appreciated that components of other drawings may be cited when necessary in describing the drawings.

Figure 1a is a view showing the configuration of a preferred embodiment of the device invention disclosed herein, Figure 1b is a view showing the configuration of a preferred embodiment of the method invention disclosed herein.

When the user requests browsing by using the user interface device 10 for browsing the content presented through the DTV, the browsing type determination unit 11 determines the type of browsing specified in the presented content (S11). ). As the user interface device 10, a remote controller (remote control) is typically represented, and the type of specified browsing newly provided by the present invention is a total of four, that is, the core four of the above-described technical ideas. Introduce a new tag or attribute into the markup language for a user interface that is suitable for.

Looking at the markup language code for the implementation of a new type of browsing through the present invention,

First, the present invention defines a property called 'index' for designating objects in groups for implementing a markup language code for moving a pointer to an object unit displayed on a DTV screen using an input device for a DTV. And, according to the pointer movement command from the user interface device 10, a markup language code scheme for moving the pointer in units of the value of the attribute is provided.

Secondly, the present invention defines a tag called 'block' for designating each divided screen when a plurality of contents are divided and presented on a DTV screen, and in this tag, an attribute for distinguishing each divided screen and a DTV screen In order to enable the pointer to be moved in units of split screen by using the number buttons of the input device, a markup language code method that defines the attribute 'index' is provided.

Third, the present invention defines a tag called 'page' for optimally displaying content on one screen, and defines an attribute called 'scroll' for adjusting the page size of the content shown on the one screen. Provides markup language code schemes.

Fourthly, the present invention divides the case of showing a content having a list, the case of showing only the title of the content through the DTV screen and the case of simultaneously showing the title and the list. For this purpose, a tag called 'list' is defined, and a markup language code scheme is defined in which the attribute 'fold' is defined for presenting the contents in a folder format.

Determination of the browsing type (S11) specifically stores the objects and attributes included in the markup language codes of the various contents presented through the DTV in the object / attribute DB 14, and the markup language of the contents presented on the DTV screen. This is done by determining whether the objects and attributes defined in the code are stored in the DB 14.

FIG. 2A illustrates an example of a markup language code for a first example of a browsing type defined through the present invention, and FIG. 2B illustrates a process of realizing the language code.

To specify a group, define an attribute called 'index' (S21), divide the group into major and subclasses, and specify index values for each category, and use the buttons on the remote control to move the pointer presented on the TV screen. While moving to the unit (S22), first to move to the index value of the major category and then to the position of the desired point by moving to the index value of the minor category.

According to FIG. 2A, it is possible to move a group unit by using HTML that is a general markup language code. When each group is moved, an object corresponding to the index value of the smallest category is displayed on the screen. Using the input device (typically a remote control) suitable for the environment, the pointer can be moved to an object such as a link or an input form. In addition, the classification stages of major and minor classifications may have more than one stage.

In the example of the markup language code shown in FIG. 2A, 'index = 1/2' refers to defining an index by dividing the group into major and minor categories, which means that the major category is 1 and the minor category is 2. do. This means that when an object corresponding to a large category index is first selected, an object corresponding to a small category index is displayed on the screen.

FIG. 2C is an example of how the small category index corresponding to the large category index is shown on the DTV screen when the major category 'index = 1' is selected, and FIG. 2D is the index of the major category when the major category index = 2 is selected. The subcategory index shows an example of how the DTV screen is displayed. When the user issues a pointer movement command using the user interface device 10, the pointer is moved in the number unit shown in FIGS. 2C and 2D, that is, in units of objects.

Other attributes (href, link, textarea, ...) shown in Figure 2a are well known to those skilled in the art to which the present invention belongs, so the detailed description thereof is weak.

FIG. 3A illustrates an example of markup language code for a second example of a browsing type defined through the present invention, and FIG. 3B illustrates an implementation process of the markup language code illustrated in FIG. 3A.

The method of having an index on an object such as a link and an input form on each screen can be realized as in the case of FIG. 2A. In this case, however, the DTV screen is divided into the number buttons of the remote controller and displayed to the user.

For example, the markup language code of FIG. 3A defines a tag called 'block' for displaying a split screen (S31), and sets an 'id' attribute to distinguish each block. A title 'attribute can be used to describe the block, and a' index 'attribute is assigned to each' block 'tag so that the pointer can be moved in units of blocks (split screen units) using the number buttons of the remote controller (S32). . 3C shows an example of the appearance displayed in units of blocks on the DTV screen. When the user presses a number button on the input device, the pointer moves to the screen corresponding to the number.

FIG. 4A illustrates an example of markup language codes for a third example of a browsing type defined through the present invention, and FIG. 4B illustrates an implementation process of the markup language code illustrated in FIG. 4A.

A tag 'page' is defined for display in one screen unit (S41). As in the case of FIG. 3A, 'id' attribute is assigned to distinguish each page, and 'scroll' attribute is assigned to each 'page' tag to set whether the screen can be scrolled (S42). In this case, by setting the property value of the scroll to off, the content beyond the size of the screen can be cut off so that the proper size of the page displayed on one screen can be adjusted to reflect the intention of the content creator.

FIG. 5A illustrates an example of markup language code for a fourth example of a browsing type defined through the present invention, and FIG. 5B illustrates an implementation process of the markup language code illustrated in FIG. 5A.

For this purpose, a tag named 'list' is defined (S51), and a 'fold' attribute is given to the 'list' tag to indicate whether the contents are to be displayed in a folder format (S52). If 'fold' is set to 'on', only the title of the list is shown on the TV screen, and if 'off', the title of the list and the contents of the list are shown on the TV screen (S53). It is presented in the left figure.

5A and 5C, by setting 'fold' of the first 'list' tag to on, only the title of the list 'Beautiful Mountain' is displayed on the screen, and the contents of the list (Mt. Baekdu, Halla, and Geumgang) are not shown. In the 'list' tag, 'fold' is set to off so that the title of the list 'Beautiful River' and the contents of the list (Duman, Yalu, and Han) are also displayed on the screen. If 'fold' is set as opposed to the above, only the title of the list 'Beautiful river' is shown, the contents of the list (Duman, Yalu, and Han) are not visible, and the title of the list 'Beautiful river' and the contents of the list (Mt. Hallasan, Mt. Geumgang) are also displayed on the screen (example on the right of FIG. 5C).

The markup language decoding unit 12 decodes the markup language code shown in FIGS. 2A, 3A, 4A, and 5A for presenting the content on the DTV screen (S12). Compiling means converting markup language code expressed in (high level language, C ++, etc.) into machine language. A representative example of markup language code is HTML, so this component 12 is responsible for the function of the HTML compiler. Since compilation is by several well-known techniques, the description of the specific method is weak.

The browsing execution unit 13 performs browsing according to the machine code of the markup language decrypted by the markup language decryption unit 12 (S13). Specific embodiments of the embodiment are as described in FIGS. 2C, 3C, and 5C.

The invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored.

Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet). Include. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.

So far I looked at the center of the preferred embodiment for the present invention. Those skilled in the art will appreciate that the present invention can be implemented in a modified form without departing from the essential features of the present invention.

Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the equivalent scope will be construed as being included in the present invention.

According to the present invention, the content creator divides the classification into the desired order and shows it to the user, so that the intention of the content creator can be given to the content, and the user can quickly and easily move the point on the TV screen.

According to the present invention, it is also possible to move the point quickly and easily and to show the index by dividing by block, thereby providing a user-friendly and comfortable interface.

According to the present invention, if the TV screen is displayed on a page basis (one screen unit), the content can be shown to the user in a good-looking manner and an effective screen configuration can be made as the content creator intends.

According to the present invention, it is also possible to efficiently use the space on the TV screen by showing only the same information as the title on the TV screen and not showing other contents but showing the entire contents when the user selects it.

That is, the present invention can easily move the points such as links and input forms by grouping them according to the tag, and by assigning blocks on the TV screen, indexes such as links and input forms for each zone can be used to facilitate the movement of points. Can be. Also, the screen configuration can be effectively performed by showing the content to be displayed on the TV screen for each page. In addition, since the contents of the contents are not shown but the user selects them, the contents of the TV screen and the space can be efficiently used.
