Hierarchical Mapping Method of Web Data and Web Data Recording Method Using the Same

The present invention relates to a hierarchical mapping method of web data and a web data recording method using the same. More specifically, strings linked in the same web site among strings constituting the content of one web site are selected from the upper web data. A hierarchical map in the form of a tree is created while going to the subordinate web data, and the user can select only the strings linked to the web data to be recorded from the strings displayed on the hierarchical map, so that the user only needs the web data. The present invention relates to a hierarchical mapping method of web data and a web data recording method using the same.

Today, the demand for information is increasing so that it is called the age of information, and accordingly, access to the Internet, which is likened to a sea of information, to acquire necessary information and enjoy entertainment is becoming commonplace. In particular, access to and use of the World Wide Web (WWW, hereinafter referred to as the web) that supports images, music, or moving images in addition to texts is congested.

However, the process of searching for the necessary data on the Internet requires a lot of effort and time, especially when accessing the web to search for information, because much more data to receive a lot of communication costs. Therefore, when searching websites, instead of searching for data transmitted in an online state connected to a communication network in real time, the data is converted into the form of received digital data or converted into an analog broadcast signal. After the data is stored in the recording medium, the stored data is reproduced to retrieve the information required by the user in an offline state.

However, since the web data is composed of hyperlinked documents, as a method for storing or recording such web data on a recording medium, a web site is designated and all the links are linked below it. You can use the method of recording web data or by inputting some IP address of the user and recording only the corresponding address, but all of these methods are as follows. You have a problem.

First of all, in the case of designating one website and recording all the web data linked below, information that is not needed by the user may be recorded, which leads to waste of the recording medium and recording time. It takes a long time, and there is a problem that the search is inconvenient due to the large amount of recorded data even during playback.

In addition, when recording a desired site by using a user's specified information provider address, the user must know the information provider's address of each site, and once the user enters a site, the desired part of recording is limited. Therefore, the same problem as that of the above method of recording all data linked thereunder occurs.

Therefore, the present invention is equipped to solve the above problems, the web that allows the user to visually and hierarchically check the data linked to the site even if the user does not have accurate information about the location of the web data in a site To provide a hierarchical mapping of data units.

It is also an object of the present invention to provide a web data recording method using a hierarchical map of web data in which only necessary data can be conveniently selected and recorded;

Another object of the present invention is to provide a web data recording method using a hierarchical map of web data to confirm whether web data directly linked to the web data to be played back is recorded;

It is still another object of the present invention to provide a web data recording method using a hierarchical map of web data to confirm whether web data linked indirectly to a web data to be played back is recorded.

In the hierarchical mapping method of web data and the web data recording method using the same according to the present invention as described above, a link is included in a string included in a document first received when a web site is searched using an Internet search / recording apparatus. After determining whether there is a linked string, if there is a linked string in the received document, it is determined whether the linked string is a string linked to the same website or a string linked to another website. Store with location information of data. Subsequently, receiving the document linked to the string stored in the relative address book and repeating the process with respect to the linked strings included in the document, and hierarchically stored in the relative address book, the linked string is no longer If not, return to the parent document and repeat the above process for the other linked character strings included in the parent document. After the above process is performed for all the strings linked to the finally accessed site, the hierarchy within one site is performed. Web data map will be created.

Subsequently, the hierarchical map showing all the information linked in the web data is displayed on an external image display device, and when the user selects a character string linked to data to be recorded from the character strings included in the map, the selected character string is displayed. By using the location information stored in conjunction with the corresponding website to receive the website to record it, it is possible to selectively record the desired web data.

In this case, the screen of the image display apparatus may be divided to display and select not only the strings stored in the relative address book in which the hierarchical map is created, but also the strings stored in the absolute address book. Also, the link mark is deleted for the strings not selected at the time of recording so that the user can easily check whether they are recorded during playback, and if there is a string selected again at the lower level of the hierarchical map, the link is not present. At the same time, it is desirable to make the recording of the lower data possible by erasing the display and placing a separate identification mark at the bottom thereof.

Hereinafter, a method of preparing a hierarchical map of web data and a method of recording web data using the same according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing an example of an apparatus for performing a hierarchical map preparation method of web data and a web data recording method using the same according to the present invention. An input unit 30 for receiving a command; A modem 10 for accessing a website through a communication network and transmitting and receiving web data; An image memory 40 having a storage space in one-to-one correspondence with pixels on an external image display device 110; A broadcast signal converting unit (60) for converting each image data in said image memory (40) into a broadcast signal while continuously reading it; A recording unit 100 for receiving and recording a broadcast signal output from the broadcast signal conversion unit 50; A main memory 20 for storing web data and hierarchical structure information of the web data received by the modem 10; And controlling the modem 10 and the recording unit 100, and classifying a string linked to the same website and a string linked to another website among the web data received by the modem 10 together with the location information. And a microcomputer (MICOM) 50 stored in the main memory 20.

It comprises a; luminance / chroma signal processing unit 90 for.

2 and 3 are detailed flowcharts for creating a hierarchical map of web data according to the present invention, and FIG. 4 shows a method for selectively recording only desired data by using a hierarchical map created using the above method. As one example, a method of creating a hierarchical map and selectively recording the same using the search and recording apparatus will be described in detail with reference to FIGS. 2 to 4.

When the user decides a website to search and makes an Internet connection request through the input unit 30, the microcomputer 50 controls the modem 10 to be connected to a communication network to provide an Internet service. (Connection not shown). When the connection to the server is completed (S11), a connection is made to a site having desired information, and the data corresponding to the first document of the website is received by the modem 10 and stored in the main memory 20 ( S12). At the same time, the microcomputer 50 analyzes the data in the main memory 20 and writes the address to the image memory 40. The data recorded in the image memory 40 is converted into a three primary color signal by the RAMDAC 61, and then converted into an NTSC signal by the NTSC encoder 62 to be imaged on an external image display device 110. Is output.

On the other hand, the microcomputer 50 first determines whether there is a linked string among the strings included in the data stored in the main memory 20 (S13), and if there is a string determined to be linked, the linked address is a relative address ( It is determined whether or not it is an address in the same site or an absolute address (address existing in another site) (S14). At this time, the linked sentence string is recorded as a relative address, which means that it is a string that is linked to the inside of the first website, that is, within the same website. This is a string that is linked to a website. Subsequently, the microcomputer 50 stores the character string recorded with the relative address or the absolute address in the relative address book or the absolute address book of the main memory 20 (S15, S16), and the stored linked character string is the relative address. If the link document processing routine (routine) is called (S17).

The called link document processing routine (S20) receives the data of the lower document linked to the string stored in the relative address book immediately before the call (S21), and goes through the same determination process as when receiving the first document. In other words, it is first determined whether there is a linked string among the strings included in the received document (S22), and after determining whether the linked string is a relative address or an absolute address (S23). ), The character string recorded as the relative address or the absolute address is stored as the relative address book or the absolute address of the main memory 20 (S24, S25), but when the relative address book is stored in the relative document (calling) Hierarchically stored below the string linked to the document received immediately before), and then calling itself again (S26).

If the calling process is repeated, and it is determined that there is no longer a linked string in the received document (S22), the call is returned to the called place (S27). The search for the linked string in the document is done again.

After returning to the upper document, it is determined whether there are more linked strings among the strings after the called string (S22). If there is a string determined to be linked, the process is repeated again (S23, S24-S25). , ...), if there are no more linked strings, returns to the place where the call was made (S27). If such a call and return process is repeated and the caller returns to the place where the first call was made, and it is determined that there is no longer a linked string (S13), the above process is terminated (S18). The hierarchical map of the web data showing the linked structure of is completed.

Hereinafter, a method of selectively recording a web data desired by a user by using the hierarchical map of the completed web data will be described in detail.

The hierarchical map of the web data in the main memory 20 created using the above method is recorded in the image memory 40 so as to be displayed on the screen of the external image display apparatus 110 (S30). In this case, as shown in FIG. 5, the screen of the image display apparatus is divided into three, and a window 1 displays a hierarchical map of the web data having a tree structure as shown in FIG. 6, and for later recording selection. In the case of selecting a character string on Windows 1, in case the user cannot know the document information including the selected character string, the entire document including the selected character string among the strings displayed in the hierarchical map is displayed. It is preferable to list and display the character strings stored in the absolute address book in the main memory 20.

The user selects one or more character strings included in the document to be recorded from the hierarchical maps showing the connection information both inside and outside the website (S31). In this case, it is preferable to select a character string once by using a mouse or the like so that the selected character strings are inverted to a different color so that they can be easily distinguished from other strings that are not selected. The selection of the string can also be made for indirectly linked strings a-b and c-d as shown in FIG. In addition, when double-clicking on a string selection, all the strings linked under the string are inverted so that all the strings linked under the string can be selected. If selected, you can also use the release button to return the string to its original state without inversion.

Subsequently, the microcomputer 50 reads the location information of the web data stored in the main memory 20 together with the selected character string to control the modem 10 and access the website (S32) to receive data. do.

The data received by the modem 10 is read by the microcomputer 50 and converted into pixel data based on the output resolution and the number of colors of the external image display apparatus 110 currently set in the apparatus, and then the image. A memory address corresponding to the position to be displayed on the screen of the display device 110 is designated and recorded in the image memory 40. The image data in the image memory 40 are continuously converted into three primary color signals by the RAMDAC 61 in synchronization with a pixel clock for synchronizing with the pixel position of the screen, and the converted three primary color signals are finally output. The NTSC encoder 62 converts the signal into an NTSC signal, which is an analog signal suitable for the video display device 110 (TV, etc.). When the NTSC signal is transmitted to the external image display apparatus 110, the transmission pattern of the corresponding Internet data is displayed on the screen of the image display apparatus 110, and the NTSC signal is a luminance / chromatic signal processor in the recording unit 100. If input to 90, the microcomputer 50 controls the recording unit 100 to record the video signal of the web data on a magnetic tape (S33).

When recording the web data including the selected character string, the direct link (ef, fg of FIG. 6) is deleted at the lower level, but the link mark is deleted for the unselected character string (fg of FIG. 6). And unrecorded strings are visually distinguished so that the user can easily check whether the strings are recorded. In addition, when the link mark is deleted because it is not selected, but the selected strings (ab, cd) linked indirectly as shown in FIG. 6 are included in the lower layer, the link mark is removed from the string, such as THE MORE ... By making the same additional identification mark, it is desirable to be able to confirm that the indirectly related information is further present in the lower layer.

In addition, when recording the web data including the selected character string using the method, it is preferable to record in order of the web data including the character string located in the upper layer of the hierarchical tree structure to facilitate retrieval during reproduction.

The hierarchical mapping method of web data and the web data recording method using the same according to the present invention made as described above can be achieved by only accessing a site without a cumbersome process of checking and storing a hierarchical structure of web data in a site. It is convenient to create a hierarchical structure of web data in the web site, and it is also convenient to use it so that only necessary data can be selected and recorded, thereby reducing the time for selection and storage. In addition, it is a very useful invention that has the effect of eliminating unnecessary waste of the recording medium and thus reducing the time required to read unnecessary data during reproduction.
