The display apparatus 1 shown in FIGS. 1 and 2 divides and displays an input web page into a plurality of first blocks. 3 illustrates an example of a web page 100 having a plurality of first blocks 101 to 105, and FIG. 4 is divided into a plurality of first blocks 101 to 105 by the display apparatus 1. An example of the web page 100 is shown. As illustrated in FIG. 3, each of the plurality of first blocks of the webpage 100 refers to a unit area that may divide the webpage 100 on a visual, geometric, semantic, logical, or the like basis. 3 and 4, lines, boxes, circles, and the like shown in the plurality of first blocks 101 to 105 are actually texts, images, figures, and the like which are contents of the plurality of first blocks 101 to 105. For simplicity, it should be noted that this is a simplified illustration.

As shown in FIG. 4, the display apparatus 1 includes a plurality of first blocks 101 to 105 so that a user can recognize that the web page 100 is divided into a plurality of first blocks 101 to 105. The boundaries of the liver (see numeral 110). In addition, the display device 1 may display any one of the plurality of first blocks 101 to 105 on the screen of the display unit 13. That is, the display device 1 may allow any one of the plurality of first blocks 101 to 105 to be positioned at a substantial center of the screen of the display unit 13. In this case, the web page 100 may be enlarged at an appropriate magnification so that the user may know the contents thereof. In addition, any one of the plurality of first blocks 101 to 105 that is currently focused may be highlighted and displayed. The display apparatus 1 enables the browsing of the web page 100 by moving the focus between the plurality of first blocks 101 to 105 according to a user's operation using the up, down, left, right, and the like buttons of the remote controller 20. . Accordingly, the user can browse the web page 100 conveniently and quickly.

The controller 15 of the display apparatus 1 analyzes the input web page 100 and divides the web page 100 into a plurality of first blocks 101 to 105. The web page 100 may be divided into a plurality of first blocks 101 to 105. For example, there may be a method of using a hierarchical structure of a web page, a method of dividing based on an image, and the like. This will be described below.

In the "method of using a hierarchical structure of web pages", first, a document object model tree (hereinafter, referred to as a "DOM tree") of a web page 100 to be divided is acquired. One). Next, we run the DOM tree and extract the block that meets the condition (step 2). The condition at this time may be that:

(1) The extracted block is not the same size as the previously added block (remove duplicates)

(2) present in a certain depth (threshold for speed improvement, for example, a value within the range of 5 to 10 can be set to 6, which is an arbitrary value)

(3) The width and height of the HTML tag are more than a certain size (in consideration of readability and the size of the screen, for example, the width can be set to 120 and the height to 30).

(4) Limited to specific tags (eg DIV, UL, LI, DL, DD, P, TD, Table, IFRAME, TR, FORM, DT, OL, etc.)

(5) Blocks with a depth of 2 or more do not leave the domain of the parent node

(6) Blocks with a depth of 2 or more are in contact with the parent node either up, down, left, or right

If the blocks acquired through the above 'process 1' and 'process 2' do not contain any other child blocks inside the block, if the block size is larger than a certain size, the above-mentioned 'image-based division' Method may be used to perform partitioning (step 3). The execution process at this time may be as follows:

(1) The color of the previous y-1 coordinate and the current y coordinate by comparing the color of the previous y-1 coordinate with the horizontal line scanning for each vertical of the image.

(2) For each horizontal side of the image, the color of the previous x-1 coordinates through the vertical line scanning and the color comparison between the current x coordinates and the color comparison difference is 5 or more.

(3) In each case above, it is judged as a line when successive colors appear more than a certain number during scanning.

(4) The color comparison value is represented by selecting the largest value among the difference of values for each of R, G, and B.

(5) Finally, the segmentation is performed by performing recursive calculation based on the result of line scanning on all the horizontal and vertical points.

(6) The partitioned block extracts one that is not overlapped with the existing blocks.

In addition, if the area of the tag and the actual human view block size is not the same, or there is a white space between the blocks, so that the divided area is not good to see, the extraction process is as follows. You can adjust the coordinates of the blocks (step 4):

(1) If the block is adjacent to each other and the distance between each coordinate of the block is smaller than a certain threshold, the child block has the same value as that of the previous block in the compared coordinates (the threshold is compared with the x components). 50 for y, and 30 for y-components)

(2) This coordinate comparison is performed on the x-, y-coordinates and right-bottom x-, y-coordinates of the left-top of the block, where x is the x and y is the same regardless of the position of the component. Comparing y

According to the division of the above method, since any type of web page can be browsed by dividing it into the first block, convenient and rapid browsing is possible while maintaining readability of the information of the web page. In addition, since it can be divided into a meaningful first block, it is possible to adjust the amount of information of the web page provided to the user.

Meanwhile, the first block may have various sizes according to the property of the web page 100. If the first block is too small, for example, relatively small compared to the screen of the display unit 13, it may be inconvenient for the user to browse while moving for each small first block. Even if the magnification of the webpage 100 is enlarged, the utilization efficiency of the screen may be inferior. Here, the first block may be a block of the largest unit divided by the above-described method, for example, a method using a hierarchical structure.

The controller 15 of the display apparatus 1 according to an exemplary embodiment of the present invention provides a user with convenient browsing of the plurality of first blocks when the sizes of the plurality of first blocks of the web page 100 are small. A plurality of first blocks are merged into a second block of a suitable size so as to. 5 shows an example of such a second block 52. In FIG. 5, reference numeral 50 denotes a web page, 51 denotes a plurality of first blocks included in the webpage 50, and 53 denotes a screen of the display unit 13.

It is assumed that the plurality of first blocks 51 are significantly smaller than the screen 53 of the display unit 13 when the web page 50 is enlarged at a magnification of the readability. In the present exemplary embodiment, the first block 51 is significantly smaller than the screen 53 of the display unit 13, so that several first blocks 51 may be displayed on the screen 53 of the display unit 13. Say what you can. The size of the screen 53 of the display unit 13 is an example of a reference size for determining whether to merge the plurality of first blocks 51. In addition, the reference size determines the size of the second block 52 obtained by merging the plurality of first blocks 51. That is, how many first blocks 51 are merged into one second block 52 is determined by the reference size. For example, the size of the second block 52 may be approximated to the reference size. The number of the plurality of first blocks 51 may be determined to be smaller than the reference size and as close as possible to the reference size.

When the size of the plurality of first blocks 51 is small, the control unit 15 of the display apparatus 1 merges the plurality of first blocks 51 into one second block 52 and manipulates the user. As a result, the plurality of first blocks 51 and the second block 52 are browsed. That is, the controller 15 allows the first block not belonging to the second block 52 to be browsed while moving the focus in units of the second block 52.

The second block 52 is displayed so that the user can know its boundary, and if the second block 52 is focused, it can be highlighted. The boundary between the plurality of first blocks 51 belonging to the second block 52 may or may not be displayed. When the second block 52 is focused, that is, when any one of the plurality of first blocks 51 belonging to the second block 52 is selected, the second block 52 may be positioned at the center of the screen. have.

The criterion for merging the plurality of first blocks into one second block may be specifically as follows:

(1) When a plurality of first blocks have the same left-top x-coordinate, and are horizontally adjacent to each other up and down (adjacent when the margin between two neighboring first blocks is below a predetermined threshold) Can be considered)

(2) When a plurality of first blocks have the same left-top y-coordinate, and are vertically adjacent to each other (left and right adjacent to each other if the margin between two neighboring first blocks is less than or equal to a predetermined threshold) Can be considered)

(3) When a plurality of first blocks are siblings of the same parent and tag names are the same

By merging a plurality of first blocks recursively on the basis of the above criteria, merging is performed until the second block reaches the above-mentioned reference size.

When the plurality of first blocks are merged into the second block, the controller 15 may connect the detailed block lists of the plurality of first blocks by using one block pointer and store them in the storage unit 14. In addition, the controller 15 may set the size of the corresponding second block by using the maximum value and the minimum value of the coordinate values of the plurality of first blocks.

6 is a flowchart illustrating a control method of the display apparatus 1 described with reference to FIGS. 1 to 5. In operation 701, the display apparatus 1 receives a web page selected by a user. Next, in operation 702, the display apparatus 1 divides the received web page into a plurality of first blocks, merges two or more of the plurality of first blocks into a second block corresponding to a predetermined reference size, and displays the same. .

Next, in operation 703, the display apparatus 1 receives a user's command for web browsing. Next, in operation 704, the display apparatus 1 performs browsing for a plurality of first blocks and second blocks according to a user's command.

According to the above method, the user can browse the web page more conveniently and quickly.

As another example, the controller 15 of the display apparatus 1 may perform web page browsing by a method of focusing a plurality of first blocks at once. 7 shows a web page 60 according to the present embodiment. The description of the same or similar components as those of the embodiment of the display device 1 described with reference to FIGS. 1 to 6 will be omitted with respect to the present embodiment.

In FIG. 7, reference numeral 61 denotes any two first blocks of the web page 60, and reference numeral 63 denotes a screen of the display unit 13. As shown in FIG. 7, two first blocks 61 are adjacent to each other, and both of them may be displayed on the screen of the display unit 13. That is, the two first blocks satisfy the condition of the reference size. FIG. 7 shows an example in which the number of first blocks that are simultaneously focused is two, but the number of first blocks that are simultaneously focused is not limited thereto, and three or more first blocks may be focused at once if the reference size is satisfied. have.

Referring to FIG. 7, when the focus is shifted to any one of the two first blocks 61 while the first first block of the webpage 60 is focused while browsing, the controller 15 may include two agents. All one block 61 is focused at one time. That is, the controller 15 simultaneously displays the two first blocks 61 on the screen of the display unit 13. This can be understood as if two first blocks 61 are treated like the second block described in the above embodiment.

In the present embodiment, the two first blocks 61 are displayed so that the user can know the boundary with other neighboring first blocks, and when the one of the two first blocks 61 is focused, the two first blocks 61 are displayed. All of the blocks 61 may be highlighted. Borders adjacent to each other between two first blocks 61 may or may not be displayed. When any one of the two first blocks 61 is focused, the two first blocks 61 may be treated as one and may be positioned so that the whole is at the center of the screen.

When one of the two first blocks 61 is focused, the controller 15 omits the movement of the focus between the two first blocks 61 and immediately moves the focus between the two first blocks 61. The focus may be moved to another first block adjacent to the first block 61.

8 is a flowchart illustrating a control method of the display apparatus 1 described with reference to FIGS. 1 to 4 and 7. In operation 801, the display apparatus 1 receives a web page selected by a user. Next, in operation 802, the display apparatus 1 divides and displays the received web page into a plurality of first blocks.

Next, in operation 803, the display apparatus 1 receives a user's command for web browsing. Next, in operation 804, the display apparatus 1 performs browsing while moving the focus between the plurality of first blocks according to a user's command, and any one of two or more adjacent first blocks that satisfy the reference size is focused. If so, all adjacent two or more first blocks are displayed at once.

This makes it possible for the user to browse the web page more conveniently and quickly.

As mentioned above, the present invention has been described in detail through preferred embodiments, but the present invention is not limited thereto and may be variously implemented within the scope of the claims. For example, the above embodiment will be described using TV as an example, but the display device of the present invention can be applied to a smart phone, a mobile phone, and the like.
