CROSS-REFERENCE TO RELATED PATENT APPLICATIONS

This application claims priority from Korean Patent Application No. 10-2005-0088220, filed on Sep. 22, 2005, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

Methods and systems consistent with the present invention relate to web browsing, and more particularly, to a web browsing method and system allowing easier selection of a hyperlink in a web page, and a recording medium thereof.

2. Description of the Related Art

According to a related art known web browsing method, searching of the Internet or web surfing is performed using a web browser such as Internet Explorer. Accordingly, in the conventional web browsing method, a desired hyperlink among hyperlinks in a web page is selected using a mouse connected to an apparatus such as a personal computer (PC) for which the mouse is an information input unit or a command input unit.

Meanwhile, as the boundary between electronic appliances, such as digital televisions (TVs) and mobile phones, and PCs has been collapsing recently, the trend is for functions previously available only in a PC to now be enabled in digital TVs and mobile phones. A web browsing function, for example, is now present in some digital TVs and mobile phones.

Unlike the PC, digital TVs and mobile phones use information input units having a limited number of buttons. Consequently, the ease of use associated with web browsing using a PC having a mouse as an information input unit cannot be expected when using digital TVs and mobile phones.

In case of the PC, a hyperlink in a web page can be selected easily and quickly using the mouse as described above, but in the suggested conventional web browsing method using a digital TV or a mobile phone, a hyperlink in a web page is selected using a direction button on the information input unit. Accordingly, in the digital TV or mobile phone using the conventional method, buttons must be pressed many times in order to select a desired hyperlink. Easy and rapid selection of the hyperlink cannot be expected.

In order to improve the web browsing experience on digital TVs, mobile phones, and other electronic appliances, a web browsing method is suggested by which numbers are sequentially allocated to respective hyperlinks in a web page and, based on number information input using number buttons, a hyperlink is selected. In this web browsing method, however, if the number of hyperlinks included in a web page is large, the numbers required to be allocated increase. Accordingly, areas to display these should be secured and management of numbers allocated to respective hyperlinks becomes complicated.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

Certain exemplary embodiments of the present invention will now be described more fully with reference to the accompanying drawings.

FIG. 1 shows an example in which identification information is selectively allocated and displayed in a web page, based on the table structure of the web page and the number of hyperlinks, and based on the displayed identification information, a hyperlink is selected.

Referring to FIG. 1, an exemplary embodiment of the web browsing system includes a web server 100, a communication network 110, and a web client 120.

The web server 100 provides a web page requested by the web client 120. The web page may be a hypertext markup language (HTML) document. The web server 100 may provide a web page according to the conventional methods or provide a web page with identification information tags defined according to an exemplary embodiment of the present invention. For this, the web server 100 includes a processor 101 and a transmission and reception unit 102.

If the web server 100 provides a web page according to the conventional methods, the processor 101 transmits a corresponding web page to the communication network 110 through the transmission and reception unit 102. Accordingly, the web client 120 receives the requested web page.

However, if the web server 100 provides a web page including identification information tags defined according to an exemplary embodiment of the present invention, the processor can define identification information tags in relation to a plurality of regions of the web page to be divided based on the table structure of the web page to be transmitted to the web client 120 or based on the number of hyperlinks and the table structure of the web page, and define an identification information tag in relation to a hyperlink included in each of the plurality of regions. Definition of an identification information tag complies with a tag definition rule of the conventional hypertext transfer protocol (HTTP).

Identification information for the plurality of regions and identification information for the hyperlink may be numeric information defined differently from each other. For example, identification information allocated to the plurality of regions may be numeric information defined in the form of “1, 2, 3, . . . ” and identification information allocated to hyperlinks may be numeric information defined in the form of “{circle around (1)}, {circle around (2)}, {circle around (3)}, . . . .” An identification information tag is defined so that identification is expressed in the form of numeric information as above.

In order to provide web page defined identification information tags, the processor 101 may include a region division unit 101_1, an identification information defining unit 101_2, and a web page generation unit 101_3, as shown in FIG. 1 (reference number 101′).

The region division unit 101_1 can be implemented to divide regions of a web page to be transmitted based on the table structure of the web page or based on the table structure and the number of hyperlinks.

In the case where the regions of the web page are divided based on the table structure of the web page, when the web page to be transmitted is input, the region division unit 101_1 identifies the table structure of the web page by analyzing tag information of the web page, and based on the identified table structure, divides the web page into a plurality of regions.

However, in the case where the regions of the web page are divided based on the table structure of the web page and the number of hyperlinks, if the web page to be transmitted is input, the region division unit 101_1 identifies the table structure of the web page by analyzing tag information of the web page, divides the web page into a plurality of regions based on the identified table structure, and then checks the number of hyperlinks included in each of the plurality of regions. If the number of hyperlinks included in an arbitrary region is equal to or less than a predetermined number, the region division unit 101_1 can group the region together with at least one adjacent region. The adjacent region used for grouping can be determined in order of the increasing number of hyperlinks among regions adjacent to the arbitrary region. Accordingly, as an example, the predetermined number and an adjacent region that is the object of the grouping can be determined so that the number of hyperlinks included in the grouped region is equal to or less than 9.

The identification information defining unit 101_2 can be implemented to define only identification information tags for the plurality of regions divided in the region division unit 101_1 or to define identification information tags for the plurality of regions divided in the region division unit 101_1 and identification information tags for hyperlinks included in the plurality of regions, respectively.

In the case where the identification information defining unit 101_2 defines only identification information tags of the plurality of regions divided in the region division unit 101_1, the identification information defining unit 101_2 defines identification information tags so that numeric information such as “1, 2, 3, . . . ” is allocated in the plurality of divided regions as described above.

However, in the case where the identification information defining unit 101_2 defines identification information tags for the plurality of regions and identification information tags for hyperlinks allocated to the plurality of regions, respectively, the identification information defining unit 101_2 defines identification information tags so that numeric information such as “1, 2, 3, . . . ” is allocated in the plurality of divided regions as described above, and then, defines the identification information tags in relation to the hyperlinks so that numeric information such as “{circle around (1)}, {circle around (2)}, {circle around (3)}, . . . ” is allocated to the hyperlinks as described above.

The web page generation unit 101_3 generates a web page including the identification information tags defined in the identification information defining unit 101_2. The generated web page is transmitted to the transmission and reception unit 102.

If a web page is requested by the web client 120 through the communication network 110, the transmission and reception unit 102 transmits a web page request signal to the processor 101 and transmits a web page transmitted by the processor 101 to the web client 120 through the communication network 110.

The communication network 110 transmits and receives web pages corresponding to HTML documents, based on the HTTP protocol and link information (for example, a uniform resource locator (URL)), between the web server 100 and the web client 120.

If a web page in which identification information tags are not defined is received from the web server 100, the web client 120 allocates identification information based on the table structure of the web page and the number of hyperlinks, and performs web browsing by displaying the web page including the allocated identification information.

However, if a web page in which identification information tags are defined is received from the web server 100, the web client 120 analyzes identification information tags included in the received web page, displays the web page including identification information allocated to the plurality of regions and identification information allocated to the hyperlinks, and performs web browsing according to the identification information.

For this, the web client 120 includes a web browser 121, an information input unit 122, and a display unit 123.

If a web page in which identification information tags are not defined is received from the web server 100, the web browser 121 allocates identification information to each of the plurality of regions divided based on the table structure of the web page received from the web server 100, or based on the table structure and the number of hyperlinks, and outputs the web page in which identification information is allocated to the display unit 123.

The identification information is allocated so that numeric information of the form described above with reference to the web server 100 is overlaid on corresponding regions. Accordingly, a web page in which numbers “1, 2, 3, 4, 5, 6, 7, and 8” are allocated to respective divided regions as shown in FIG. 2 is displayed on the display unit 123.

FIG. 2 illustrates an example of a web page displayed on the display unit 123 of the web client 120 shown in FIG. 1 in which identification information is allocated to each of the divided regions.

When a web page is divided into a plurality of regions based on the table structure, the web browser divides regions based on the result of analyzing the tag information of the received web page. However, when a web page is divided into a plurality of regions based on the table structure and the number of hyperlinks, the web browser checks whether there is a region, among the plurality of divided regions, in which the number of hyperlinks in the region is equal to or less than a predetermined value. If there is a region in which the number of hyperlinks is equal to or less than the predetermined value, the web browser 121 redefines the divided region so that the region is grouped together with at least one region among regions adjacent to the region, in order of the increasing number of hyperlinks included in each region. The predetermined value and the adjacent region are identical to those described above with reference to the web server 100, respectively.

If a user inputs an identification information item through the information input unit 122 based on the web page displayed as shown in FIG. 2, the web browser 121 outputs to the display unit 123 a web page formed with hyperlinks included in the region corresponding to the input identification information. If one hyperlink is selected based on the output web page formed with the hyperlinks, the web browser moves from the web page formed with the hyperlinks to data connected to the selected hyperlink. The data connected to the hyperlink may be a web page, a web site, a picture, a sound, a video, a document, a downloadable file, and so forth.

When the web page formed with hyperlinks is displayed, identification information for each hyperlink may not be allocated in the web page formed with the hyperlinks. In this case, by using a direction key located on the information input unit 122, a desired hyperlink can be selected in the displayed web page formed with the hyperlinks.

However, in order to display a web page in which identification information on each hyperlink is allocated as shown in FIG. 3, the web browser 121 can allocate identification information in each hyperlink included in a selected region and output the web page formed with hyperlinks including allocated identification information.

FIG. 3 illustrates another example of a web page displayed on the display unit 123 of the web client 120 shown in FIG. 1 in which region 7 is selected among divided regions on the main web page and a web page formed with hyperlinks included in the selected region 7 is displayed on the display unit 123.

FIG. 3 shows a case in which numeric information such as “{circle around (1)},{circle around (2)},{circle around (3)}, . . . ” is allocated as identification information for each hyperlink. When the web page formed with hyperlinks is as shown in FIG. 3, if “{circle around (2)}” is input as hyperlink selection information through the information input unit 102, the web browser 121 moves to data connected to a hyperlink “Oh, whirl!—a bridge breaking a stereotyped idea.” That is, the web browser 121 moves to a web site or web page corresponding to the hyperlink, by using the URL of the hyperlink “Oh, whirl!—a bridge breaking a stereotyped idea.”

At this time, in order to distinguish identification information items allocated to divided regions and hyperlinks, numeric information items defined in different forms are displayed in the web page displayed on the display unit 123, but the information input unit 122 can be implemented so that identical numeric keys can be used to input selection information for both regions and hyperlinks.

That is, when the web page shown in FIG. 2 is displayed on the display unit 123, if numeric key information is input form the information input unit 122, the web browser 121 can recognize it as information to select a divided region. If a divided region is selected and the web page formed with hyperlinks is displayed on the display unit 123, and then numeric key information is input from the information input unit 122, the web browser 121 can recognize it as information to select a hyperlink.

Meanwhile, when a region among the plurality of regions shown in FIG. 2 is selected and a web page formed with hyperlinks is output, the web browser 121 can delete identification information allocated to the plurality of regions as shown in FIG. 4. FIG. 4 illustrates another example of a web page displayed in the display unit 123 of the web client 120 shown in FIG. 1 and shows a case in which when a region among a plurality of regions is selected and a web page formed with hyperlinks is output, identification information allocated to the plurality of regions is deleted.

In order to perform web browsing as described above (when a web page from the web server 100 in which identification information tags are not defined is received), the web browser 121 can include a transmission and reception unit 121_1, a region division unit 121_2, and a web page output unit 121_3 as shown in FIG. 1 (reference number 121′).

The transmission and reception unit 121_1 receives a web page from the communication network 110, provides the received web page to the region division unit 121_2, and if information on a selected hyperlink (for example, URL information) from the web page output unit 121_3 is input, performs processing to move to data linked to the information corresponding to the input hyperlink.

If the web page is received, the region division unit 121_2 divides the web page into a plurality of regions based on the table structure of the web page or based on the table structure and the number of hyperlinks, as described above.

The web page output unit 121_3 allocates identification information to each of the regions divided in the region division unit 121_2, outputs the web page in which identification information is allocated, and if one of the plurality of regions is selected based on the identification information displayed on the output web page, outputs a web page formed with hyperlinks included in the selected region. At this time, in order to display identification information allocated to each hyperlink in the web page which is formed with the hyperlinks and is to be output, the web page output unit 121_3 can allocate identification information to each hyperlink and output the web page formed with hyperlinks having allocated identification information.

The information input unit 122 inputs identification information displayed on the display unit 123 and information to select a hyperlink.

The display unit 123 displays a web page output from the web browser 121.

The web client 120 may be an electronic appliance including an information input unit including a plurality of buttons and a display unit, such as a digital TV or a mobile phone.

FIG. 5 is a functional block diagram of a web browsing system according to another exemplary embodiment of the present invention. FIG. 5 shows a case in which identification information is selectively allocated to a web page and displayed by using information set in advance according to the usage pattern of a user, or identification information is selectively allocated to a web page and displayed by using information set in advance according to the table structure of a web page, the number of hyperlinks, and the usage pattern of the user, and then a hyperlink is selected using the displayed identification information.

A web server 500 and a communication network 510 are identical to the web server 100 and the communication network 110, respectively, shown in FIG. 1.

If identification information tags are defined in a web page received from the web server 500, the web client 520 displays on a display unit 523 the web page which includes identification information tags for regions divided by the table structure of the web page and identification information for hyperlinks of each of the divided regions. However, if identification information tags are not defined in the web page received from the web server 500, the web client 520 allocates sequential identification information tags to regions divided by the table structure of the web page and hyperlinks within each of the divided regions, and then displays on the display unit 523 the web page in which identification information is allocated.

At this time, regardless of whether identification information tags are defined in the web page received from the web server 500, the web client 520 selectively allocates and displays identification information for hyperlinks in the web page using information set in advance according to the usage pattern of the user. For this, the web client 520 detects specific hyperlinks among hyperlinks included in the received web page, based on the information according to the usage pattern of the user, which is set in advance. The information according to the usage pattern of the user is bookmark information and/or hyperlink information set in advance by the user and/or hyperlink information set based on information on links the user accessed recently. Accordingly, the specific hyperlink in the received web page may match with information set according to the usage pattern of the user.

If a specific hyperlink is detected, the web client 520 allocates identification for the detected hyperlink and displays a web page including the allocated identification information. That is, the web client 520 can display a web page in which only identification information for the specific hyperlinks is displayed as shown in FIG. 6, or can display a web page in which identification information for the specific hyperlinks is allocated and identification information for each of the regions divided based on the table structure of the web page and hyperlinks of a selected region is allocated as shown in FIG. 7. Referring to FIGS. 6 and 7, identification information for specific hyperlinks is function key information, such as “F1, F2, F3.” However, for identification information for specific hyperlinks, any one of numeric information and predetermined function key information can be used.

In order to perform the operations described above, the web client 520 comprises a web browser 521, a database 522, a display unit 523, and an information input unit 524.

The database 522 stores information about the user's usage pattern of hyperlinks. The information stored in the database 522 may be updated whenever the user moves to data connected to a hyperlink.

The web browser 521 detects a specific hyperlink among hyperlinks included in the web page by referring to the database 522 and outputs a web page further including identification information for the detected specific hyperlink.

When the web page further including the identification information for the specific hyperlink among hyperlinks included in the web page is output, the web browser 521 may include a transmission and reception unit 521_1, a specific hyperlink detection unit 521_2, and a web page output unit 521_3, as shown in FIG. 5 (reference number 521′).

The transmission and reception unit 521_1 is the same as the transmission and reception unit 121_1 of FIG. 1.

The specific hyperlink detection unit 521_2 detects a specific hyperlink in an input web page by referring to the database 522. That is, the specific hyperlink detection unit 521_2 detects as a specific hyperlink a hyperlink matching information stored in the database 522, among the hyperlinks included in the web page. The web page output unit 521_3 allocates identification information to the specific hyperlink and can output a web page including identification information allocated to the specific hyperlink, as shown in FIG. 6.

Also, when a web page in which identification information for the specific hyperlinks is allocated and identification information for each of regions divided in a table structure of the web page and hyperlinks of a selected region is allocated is output, the web browser 521 can include a transmission and reception unit 521_4, a region division unit 521_5, a specific hyperlink detection unit 521_6, and a web page output unit 521_7, as shown in FIG. 5 (reference number 521″).

The transmission and reception unit 521_4 is analogous to the transmission and reception unit 521_1.

The region division unit 521_5 is analogous to the region division unit 121_1 of FIG. 1, and the specific hyperlink detection unit 521_6 is analogous to the specific hyperlink detection unit 521_2. The web page output unit 521_7 outputs to the display unit 523 a web page in which identification information is allocated to each of the regions divided in the region division unit 521_5, hyperlinks of a selection region, and a specific hyperlink detected in the specific hyperlink detection unit 521_6, so that the web page as shown in FIG. 7 is displayed.

FIG. 8 is a flowchart of the operations of a web client in a web browsing method according to another exemplary embodiment of the present invention. Referring to FIGS. 1 and 8, a web page is divided into a plurality of regions based on the table structure of a web page to be displayed on the display unit 123 of the web client 120 in operation 801.

A web page including identification information allocated to each of the plurality of regions is displayed on the display unit 123 of the web client 120 in operation 802. Accordingly, the web page shown in FIG. 2 can be displayed on the display unit 123. The identification information can be allocated by the web client 120 or the web server 100. That is, if the web server 100 provides a web page including identification information tags defining identification information, the web client 120 can display a web page including identification information based on the result of analyzing the identification information tags. However, if the web server 100 provides a web page not including the identification information tags, the web client 120 can allocate identification information to the regions in order of time that a region is divided and display the web page including the allocated identification information.

If a region among the plurality of regions is selected based on the displayed identification information, the web client 120 displays a web page formed with hyperlinks included in the selected region on the display unit 123 of the web client 120 in operations 803 and 804.
