Method for automatically connecting the internet by using additional information inserted to TV Vertical Blanking Interval}

The present invention relates to a method for automatically accessing the Internet using additional information inserted in a TV Vertical Blanking Interval (VBI), and in particular, to decode additional information of an Internet site address and name inserted in a TV VBI. After storing the information on the remote control device using infrared rays, the information on the Internet site is transmitted to a separate infrared input port or IrDA infrared receiver installed in the computer, and additional information inserted in the TV vertical blanking interval (VBI) that automatically accesses the Internet site is stored. The present invention relates to a method for automatically accessing the Internet.

In general, the Internet TV method accesses a website by a website address including intercast information received from a television broadcast signal, and uses a modem for internet communication by using an intercast method, which is about 28.8 kbps. In the conventional method, Internet address information is directly displayed on TV screen contents, which the viewer remembers and inputs directly into the computer.

However, since the viewer must remember the Internet site address (URL) displayed on the TV screen, it is inconvenient because it is necessary to input directly using a computer keyboard when attempting to access the Internet website.

The present invention has been proposed to solve the above-mentioned problems of the prior art, and an object of the present invention is to insert a TV vertical blanking interval (VBI) when a user wants to induce a connection by notifying a viewer of a relevant Internet site among TV broadcast contents. The present invention provides a method for automatically accessing the Internet using additional information inserted in a TV vertical blanking interval (VBI) for a viewer to conveniently access an Internet site by transmitting and receiving an infrared signal including an internet address and a name using the additional information.

VBI: Vertical Blanking Interval

In order to achieve the above object, the present invention (a) receives a composite video signal including a horizontal signal, a vertical signal and a synchronization signal from a TV, decodes a vertical blanking interval (VBI) signal, and decodes the VBI signal. A VBI signal decoding and infrared transmitting step (S100) of converting and transmitting character information including an internet address and a name (URL), which are additional information obtained by decoding, into an infrared signal; (b) The infrared signal is received and temporarily stored, the URL is displayed on a liquid crystal display (LCD), and the information about the Internet address and the name (URL) is converted into an infrared signal by pressing a corresponding selection button. Infrared transmission and reception step (S200) to be converted and transmitted; And (C) receiving an infrared signal through a separate infrared input port or IrDA port installed in a computer, extracting URL information from related software, executing a web browser, and automatically accessing the web site. S300) provides an automatic Internet access method using the additional information inserted in the TV vertical blanking interval (VBI).

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Referring to FIG. 1, a system for automatic access to the Internet using additional information inserted into a TV Vertical Blanking Interval (VBI) according to the present invention includes a VBI signal decoder 1 and an infrared transmitter. 2) a computer (4) with memory and an infrared transmitter / receiver (3) and a separate infrared input port or IrDA port and associated software.

The VBI Signal Decoder 1 receives a composite signal including a vertical signal, a horizontal signal, and a synchronization signal from a TV, decodes the VBI signal, and includes an Internet site including an Internet address and a name (URL). Internet site) information corresponding to text information is provided to the infrared transmitter 2.

The infrared transmitter 2 receives the Internet site text information and converts it into an infrared signal including an Internet address and a name (URL) and provides the same to the memory and the infrared transmitter / receiver 3.

The memory and the infrared transmitter / receiver 3 include a memory capable of storing a URL, a liquid crystal display (LCD) capable of displaying a URL, and a selection button, and transmit and receive infrared signals.

The computer 4 in which the software related to the separate infrared input port or IrDA port is installed receives an infrared signal including the Internet address and a name (URL) and extracts URL information from the software to generate a web browser (WWW Browser). Run it and connect to the Internet site.

For reference, the IrDA is a computer industry standard for infrared communication between a computer and a computer, a computer, and a peripheral device.

2 is a flowchart illustrating the operation of the VBI signal decoder and the infrared transmitter 10.

Check whether it is a start code indicating the start of the decoded Internet address and name (step S1) or repeat this process and if so, store the Internet address and name in a temporary memory (step S2). The information stored in the temporary memory is transmitted in the infrared in the form of pulse width modulation (PWM) (step S3).

3 is a flowchart illustrating the operation of the infrared transceiver 20.

Check whether the infrared signal with the Internet-related information is input (step S4) or repeat this process, and if the infrared signal with the Internet-related information is input, the relevant information is stored in the memory and displayed on the LCD screen. (Step S5), check whether the button corresponding to the desired Internet address of the Internet address is pressed (Step S6). If the corresponding button is not pressed, repeat this process, and if the corresponding button is pressed, the Internet address information is infrared signal. And transmits to the computer 30 (step S7).

4 is a flowchart illustrating the operation of the computer 30 in which software associated with a separate infrared input port or IrDA port is installed. Check if the infrared signal with Internet information is input to a separate infrared input port or IrDA port (step S8). If not, repeat this process and if so, launch the web browser (step S9). The site is moved to the site using the received Internet address (step S10).

Therefore, when a viewer watches TV, the address information of a web site related to the TV program is automatically obtained by transmitting and receiving an infrared signal including an Internet address and a name using additional information inserted in the TV vertical blanking interval (VBI). Not only can you get it, but you can also access the web site conveniently.

As described above, the Internet automatic access method using the additional information inserted in the TV vertical blanking interval (VBI) according to the present invention, the viewer automatically obtains the address information of the Web site associated with the program while watching TV. In addition, the website can be conveniently accessed, and broadcasters can easily advertise the website associated with the program to induce access, and in the case of commercials, they can advertise their website and induce access. It can be effective.

Although the above has been described with reference to the preferred embodiments of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the invention as set forth in the claims below. It will be appreciated.
