In the following, examples of displaying various categories and categories, examples of block designation, that is, examples of displaying categories by alphabetical category, category by genre, empty block or image block, and expanded blocks and page blocks using the same are described in more detail. Explain.

FIG. 5 is a diagram illustrating an example in which a category according to each letter of various languages and an alphabetical order in Korea are included. Here, the alphabetical category may be replaced with the abc category in the case of the English alphabet.

Referring to FIG. 5, the music list is grouped in order of go, me, da, and la in order to go to category (301). It can be seen that it is included as (311). By the way, the next category of the category A is not the category B, but is composed of the category C, 302, which means that the content 312 included in the category C, the category C, only meets you for the first time. At this time, there are only two in La Lala, so I, Da, and La are grouped together to form a block to facilitate a block-by-block search. The lower part of the alphabetical category shows that the block search can be performed by moving the classification by the four-way movement key, and selecting the corresponding block by pressing the OK key. In addition, when the genre sequence key, which is a circular key, is pressed, the alphabetical categories can be rearranged into categories by genre.

In other words, the alphabetical category can be configured in a block consistently according to each letter, but can be smartly configured according to the number of contents belonging to each letter. For example, if the minimum number of contents constituting one block is three, the temporary category constitutes a single block, whereas the b category, the multi category, and the category D constitute three blocks. In this case, even though the category does not have any content, the block name can be added to prevent user confusion. If the number of categories is more than four, the abbreviated expression can be automatically displayed. For example, when a town category, a bar category, a company category, and a subcategory are designated as one block, the block may be displayed as a town category.

In the step S11 of designating one or more categories as a block and simultaneously displaying the category and the content belonging to the category, the category may also be expressed as an empty block.

6 shows an example in which the categories are grouped according to news of each genre, and the categories are displayed as empty blocks. In the case of displaying as an empty block, it may be mainly used when there is no specific title of the category by genre or it is difficult to determine the title.

Referring to FIG. 6, the genre-based news is classified into political news, economic news, and the like, and the content of the political news includes problems such as extension of President Roh's dispatch, humiliation of President Kim Seung-yeon, and half-price apartments. President Hwang Chang-gyu's reversal, fear of naval combat deterioration, and the other president hate it and designate it as the first empty block (401). It can be seen that the focus of the four-way navigation key is located in the political news.

The focus of the four-way navigation key is in the first empty block 401 of the political news. The content following the political news is economic news, and the content of the economic news 412 currently displayed on the screen is two times the national presale price increase rate and the stock market share price crash. When the focus of the four-way navigation key moves to the next second empty block 402 of the political news, the focus can be shifted to the economic news, and the detailed news can be viewed by placing the focus on the desired news and selecting it. .

News that does not currently appear on the screen with the content of the economic news will be presented on the next screen if the third empty block (not shown) is designated by moving the focus down on the second empty block 402 down.

By displaying a category as such an empty block, it is possible to move quickly between blocks using up and down keys along the block. The location of the empty block may be left as shown, but is not limited thereto and may be placed on the right side or the top or bottom of the content for each category.

The category may be displayed in the empty block by specially designating a title of the category. For example, a "political news" title covering the content 411 of the political news of FIG. 4 is placed in the first empty block 401 and a "economic news" covering the content 412 of the economic news is created. It may be located within two empty blocks 402 to clearly indicate the characteristics of the category.

7 illustrates an example of another image block in which an image for each category is expressed in an empty block of the category.

Referring to FIG. 7, an image representing a predetermined content included in the category is displayed on each block of the category arranged in alphabetical order. The first image block 501 represents an image of "fine time" in the content 511 of the first image block, and the second image block 502 represents the "first encounter with you" of the content 512 of the second image block. When "is the image. The image may be represented as a video or may be set as a desired image. This image allows the user to find the desired content more quickly.

FIG. 8 is a diagram illustrating an embodiment of an expanded block representing a block of a category and some content included in the category on a screen of the digital device.

Referring to FIG. 8, an alphabetical category is formed, and the categories are sequentially displayed on the screen, such as category 601, me, da, la category 602, town category 603, bar-child category 604, and tea category 605. , Car, and other categories 606 are arranged. The category 601 includes a total of four contents 611, and thus, is labeled "(4)" in the drawing, and the category d. 602 includes a total of two contents 612. I, C, and la (2) ". As described above, the minimum number of contents in the category B, D, and C of the category 602 forms one block, and in this case, three, and less, the contents of the categories B, D, and R are combined to form one category. Reference numerals 613, 614, 615, and 616 denote the contents of the town category 603, the bar to child category 604, the car category 605, the car, and other categories 606, respectively.

Currently, the content displayed on the screens of all categories 601, 602, 603, 604, and 605 is one by one, and only the first content is shown here. The focus is located in the temporary category 601, and only the contents "611, the memories of the 872 70s" appear as the content 611 of the temporary category 601. When the focus shifts to "Fine time, memories of the 872 70s", all the contents 611 in the temporary category 4 appear. The unfolding block allows you to display more categories on one screen and move faster between blocks.

9 is a diagram illustrating an example in which a page changes as a block moves.

Referring to Figure 9, the phone book is organized in the order of a, b, c order. If a certain category that appears on one screen is designated as a block and the focus is moved to the next block, the screen is also switched. As shown in the first screen 721, a category 701 is designated as a block and content 711 included therein is displayed. When the block is moved downward by pressing the four-way movement key, the next content 712 appears on the second screen 722 and it can be seen that the focus is located in the a category 701 including the same.

If the focus of the four-way movement key is moved to the next block, the a category 701 block has the focus, and the third screen 723 includes the content 713 and the b category 702 included in the a category 701. Content 714 is displayed. Again, the down arrow key can give focus to the b category 702 block.

When the focus of the four-way movement key is moved to the next block, the last content of the category 702 is shown on the right screen 715, and the contents 715, 716, and 717 included in each category are displayed on the fourth screen ( 724.

Here, the c, d, ㅁ category 703 satisfies the minimum number of contents by adding up the total number of contents of the category, and thus, c, d, and ㅁ are collectively represented as one category. According to an embodiment of the present invention, a predetermined category displayed on one screen is designated as one block, and the screen is changed according to the block movement, so that block navigation similar to the page movement can be executed.
