Description

Internet Information Processing Method of Internet Television

The present invention relates to a method for processing Internet information of an Internet television. More particularly, the present invention utilizes intercast information received from a television broadcast signal in an Internet television capable of retrieving Internet information as menu information on an Internet mode. The present invention relates to a method for processing internet information of an internet television that enables a search to be performed more quickly and accurately.

Recently, the use of the Internet service to provide a variety of communication information for a specific subscriber terminal through the Internet Service Provider (ISP) on the information communication network has been spreading, the communication connection of the Internet service is a TCP / IP method It can be executed by a web browser program such as mosaic or netscape on a personal computer (PC) or a workstation equipped with a modem.

At this time, the Internet service not only transmits and receives files by the former Goper or FTP (File Transfer Protocol) service, but also forms a HTML (Hyper Text Makeup Language) document by HTTP protocol by connecting to the Internet from the ISP side. Web (WWW) information as multimedia information reproduced together with predetermined image information (e.g., JPEG, GIF, or PCX format) or audio information (e.g., Real-Audio). The hypertext function employed in an HTML document used as a language defining such web information is widely used, and the hypertext mark designates a portion where a hypertext mark is displayed, and another web is controlled by a mouse click or an enter key operation. It allows for connection with information.

On the other hand, in the television, text information and image information included in web information provided by a predetermined ISP that is provided with a dedicated modem for Internet service, which was limited to a personal computer or a workstation-class computer. For example, Internet televisions with Internet service functions for converting them into video signals of a television video standard such as NTSC system and playing them through a CRT screen have been developed and commercialized.

In such an Internet television, a web browser program stored in a nonvolatile memory such as a ROM is started to receive web information provided from an ISP through a modem to process data through a microprocessor. The program and related software programs are operated to enable the recognition and display of HTML document files of the web information, and the execution commands in the communication information are transmitted to the microcomputer (Micom). The image information can be reproduced through a CRT screen while stored in a volatile memory such as a RAM.

However, in such an Internet television, when a desired website is to be searched, a dedicated search engine provided by a server must be operated to search and input a search word related to a desired website, and a search term is incorrectly input. In this case, the search results are also displayed incorrectly, so it takes a long time to find the desired website, and even though the website is accessed, the still image file or the text file defined in the website must be received and displayed on the screen. It is inconvenient that it takes a long time to reproduce a complete web page screen.

Accordingly, the present invention has been made in view of the above circumstances, and forms a menu screen for website search by a website address included in intercast information received from a television broadcast signal in an Internet television, for each website. It is an object of the present invention to provide a method for processing internet information of an internet television, which stores a file of a web page in advance and enables a quick and accurate retrieval in an internet mode.

According to the Internet information processing method of the Internet television according to the present invention for achieving the above object, in the Internet television capable of retrieving the Internet information through a modem, the intercast data transmitted in the vertical blanking period of the television broadcast signal is transmitted A first step of receiving the web site address data and menu display information, and a second step of displaying the stored menu display information as a menu screen indicating a plurality of websites when accessing the Internet information according to the Internet mode; When a menu item of a predetermined website is designated on the menu screen of the displayed web site, a third step of accessing a corresponding website by the website address corresponding to the designated menu item and receiving Internet information It provides a method of processing Internet information consisting of Internet television.

According to the present invention configured as described above, a plurality of website addresses included in the intercast information extracted from the vertical blanking period of the television broadcast signal in the Internet television, menu display information for the plurality of websites, and respective websites Receives and saves the webpage file for and when the Internet mode is executed and the Internet connection is established, the menu display information of the plurality of websites is displayed in a tree structure, and the predetermined menu is displayed on the screen of the displayed menu display information. When a menu item for a web site is designated, a web site is accessed using a corresponding web site address, a related web page file stored in advance is read out, and a screen is quickly displayed as an initial screen.

Next, the operation of the present invention made as described above will be described in detail with reference to the accompanying drawings.

First, when a television broadcast signal of a predetermined broadcast channel is tuned through the tuner 2 and is intermediately amplified by the video IF unit 4, the video amplifier 8 uses the mode switching unit 8 to display the video of the television broadcast. The signal is amplified by the signal, and the image signal processing unit 10 processes the image signal on the signal-amplified image signal so that a predetermined image is reproduced on the CRT screen by the amplification driving operation of the image output unit 12. .

At this time, the sync separator 14 separates the sync signal from the video signal from the video amplifier 8, and the data extractor 16 includes the intercast included in the vertical blanking period of the separated sync signal. While extracting the data, the transmission data decoder 18 outputs the address data and the web page file for the website from the extracted intercast data to the controller 28 to be stored in the data memory 26, The data of the menu display information for the web site is stored in the display data memory 20.

In this state, when the mode switching to the Internet mode is performed by the key operation of the function setting unit 24, the control unit 28 switches the mode switching unit 6 in accordance with the Internet mode, and the modem. Dialing through 30 is connected to an Internet server performing an Internet service, controlling the transmission data decoder 18 to display menu display information of a website stored in the display data memory 20, and then displaying the display signal processor 22. As the screen is displayed through the display signal processing operation of FIG. 2A, as shown in FIG. 2A, the menu display screen 40 for the plurality of websites causes the main menu items and the sub menu items to be displayed in the form of a tree structure. In addition, the initial screen 42 of the Internet service supplied under the data processing of the data processing processor 32 is simultaneously displayed.

On the other hand, when a predetermined website is designated on the menu display screen 40 for the screen displayed website by the key operation of the function setting section 24, the controller 28 enters into the data memory 26. In addition to connecting to the corresponding website by the stored address data of the corresponding website, the web page file according to the website is transferred to the data processing processor 32 so that the initial screen of the desired website is entirely integrated. To be displayed (see FIG. 2B).

According to the present invention made as described above, when receiving the menu information of the desired website through the intercast information superimposed on the television broadcast signal of the air in the Internet television, and designates a predetermined website, the corresponding website By allowing access and retrieval, it has the advantage of enabling fast and accurate retrieval of websites on desired Internet services.
