DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcast receiver related to a computer network such as the Internet and a method of accessing the computer network.

[0002]

2. Description of the Related Art In recent years, the Internet has become widely known as a worldwide network. In the Internet, a network is formed such that terminals are connected via, for example, a telephone line or a dedicated high-speed data line, and transmission and reception are performed on a worldwide scale.
In addition to sending and receiving e-mail by business and individuals,
Also referred to as so-called Internet surfing, in which a large number of providers who provide various types of information on the Internet are accessed, browsed, and obtained various types of information, generally referred to as Web sites. With the spread of computer devices including so-called personal computers, the use of the Internet has begun to provide an environment that can be easily used by individuals as well as businesses.

In order to use the Internet as described above, software for accessing and browsing a Web site, which is generally called a browser, is installed in a computer device, and the browser can be used by the browser. I have. Then, in order for the user to access a desired Web site provided on the Internet, for example, the browser software is started up and an access display is performed on a monitor display screen. Then, on the access screen, the user inputs the address (URL: Uniform Resource Locator) of the homepage on which the desired Web site is provided by using a keyboard or the like, and then accesses the homepage of the address input by a predetermined operation. Is executed. When the specified homepage is accessed, an image of the accessed homepage is displayed on the monitor screen. The user searches for a page of necessary information from this homepage and jumps to the desired page. Information can be obtained.

[0004]

As described above, the operation of the user to access a desired Web site via the Internet requires the input of an address, but the user must input the address of the desired Web site. If you do not know it, you cannot enter it. Therefore,
Generally, a user purchases an information magazine in which a lot of information and addresses of Internet websites are posted, or personally obtains information by some other means.
I needed to find information on the site.

[0005] Further, since the address is a combination of characters and symbols such as symbols, alphabets, and numbers, input is usually made with a keyboard. However, since the number of digits is considerably long, several tens of digits,
Entering an address is a relatively cumbersome operation,
The possibility of inputting an incorrect address is also increased, which is an obstacle for easily accessing a target Web site.

[0006] Therefore, a keyword is input as a search item so that the user can quickly obtain a Web site that the user wants to search, and the Web searched based on the keyword is input.
Services such as providing the address of the b site have been started. However, such a service currently only supports English-speaking countries, and is, for example, hardly familiar to general users in other languages.

[0007] The browser software includes "bo
A function called “ok mark” is provided. For example, when a user may access the currently accessed and browsed Web site again and wants to memorize the address of the Web site, the user may select “book”. m
With the function of “ark”, the information of the address of this Web site can be registered in a book mark list. With this, when you decide to browse this website again later,
By calling the address of this Web site from the list of marks, the user does not need to perform an input operation of the address using the keyboard. However, even in this case, when accessing the target Web site for the first time, the operation of inputting the address using the keyboard is required, so that it is not possible to completely save the trouble of inputting the keyboard.

In other words, when using the Internet, relatively troublesome operations such as obtaining addresses and inputting the obtained addresses are required. Therefore, in order to allow the user to enjoy the Internet more easily than in the current situation and to further spread the use of the Internet, it is naturally preferable to solve the above-described problems.

[0009]

In order to solve the above-mentioned problems, a broadcast receiver for receiving a broadcast for transmitting data together with a video signal according to the present invention comprises a receiving means for receiving a broadcast and a receiving means. Separating means for separating data from a received signal, identifying means for identifying whether or not the data separated by the separating means is information relating to a computer network, and separating the data separated by the identifying means into a computer network And storage means for storing the separated data when the information is identified as the information.

According to the above configuration, it is possible to fetch and store address information from data transmitted together with a video signal, and it is not necessary to search for an address.

The method for accessing a computer network according to the present invention includes a step of receiving a broadcast for transmitting data together with a video signal, separating data from the received signal, and determining whether the separated data is information relating to the computer network. When the separated data is identified as information about a computer network, the information about the computer network is stored, and the computer is connected to the computer network based on the stored information about the computer network. .

According to the above-described access method, an address list can be created using the stored address information, so that it is not necessary to input an address using a keyboard, and there is no mistake in inputting an address.

By generating a GB signal and outputting it to the display device 13 via the RGB switch 12, the page of the accessed Web site can be displayed.

In the present embodiment, since the Web site accessed at this time is likely to be browsed again by the user with interest, the address data is automatically registered in the address list area 10a. It is composed of

When the user wants to see the current status of the address list, the user performs a required operation of the operation unit 14 to display an address list as shown in FIG. In the display screen P shown in FIG.
Under the title "Internet address list", the addresses of the three Web sites (address display 30) are the titles 3 of the teletext program corresponding to each address.
1 and the program number 32 are displayed.

When the address list is displayed as shown in FIG. 4, the controller 8 reads the address of the Web site stored in the address list area 10a of the Internet address memory 10 together with the related teletext information data, and reads this. The supplied data is supplied from the data decoder 5 to the display circuit 6, where an image signal of an address list is generated,
This is realized by supplying the display device 13 as a GB signal. In the above description, the state in which the teletext shown in FIG. 3 is displayed is shifted to the display of the Internet address list shown in FIG. 4, and at this time, the data of the data from the address list area 10a is controlled by the controller 8. Although it has been described that reading and display control are performed, the display can be shifted from the Internet browser screen to the display of the Internet a address list in FIG. In this case, based on the programming of the software stored in the Internet connection unit 9, the address list area 1 is

It is supplied to the terminal T3 of the RGB switch 12. And R
The display of the Internet address list is performed by supplying the RGB signals to the display device via the GB switch 12.

The display form of the display screen P shown in FIG. 3 and FIG. 4 is merely an example, and various other forms can be considered. For example, the display form may be easily used by the user according to actual use conditions. In addition, any information such as the title of the Web site to which the address is provided is transmitted as a broadcast wave, and such information is displayed on the display screen P shown in FIGS. 3 and 4. Is also conceivable.

In the state where the address list is displayed as shown in FIG. 4, the user selects a desired Web site address from the displayed address list by a predetermined operation of the operation unit 14. It is assumed that it is specified. Then, the display device 13 switches from the display of the address list to the screen of the Internet browser, and the address of the Web site specified on the browser software is automatically input. Then, the Internet connection unit 9 accesses this Web site and accesses the accessed Web site.
An operation for displaying the image of the site b on the display device 13 is performed.

As can be seen from the above description, in the Internet browser system constructed with the network device of the present embodiment, the user receives the teletext of the television to receive the address of the Internet Web site. Information can be obtained.
Since a wide variety of programs including news and various entertainments are broadcast as teletext, a large number of Web site addresses provided in correspondence with these program contents can be obtained in a wide variety of genres. . Therefore, the user can obtain a great deal of Web site information without purchasing an information magazine or the like separately.

Also, the data of the Web site address provided in this way is taken in as an address list, and a desired Web site can be accessed by selecting and specifying the Web site address from this address list. Has been. For this reason, the user does not need to perform any troublesome and highly erroneous operation that has been performed on a personal computer or the like, such as inputting with a keyboard according to the character string of the address. If necessary, the user operates the operation unit 1

Then, in step F102, as described with reference to FIG. 2, teletext data is extracted from the video signal of the received channel and fetched from the data decoder 5. In order to reduce the capacity of the teletext data memory, data before being decoded by the data decoder 5 can be stored in the teletext data memory. In step F103, reference is made to the extracted data obtained by the data decoder 5, and it is determined whether the data referenced in the next step F104 is Web site address data or ordinary teletext data. At the time of this determination, as described with reference to FIG.
It is sufficient to determine whether or not p.

If it is determined in step F104 that the data is the address data of the Web site, the process proceeds to step F105, and the address data of the Web site is stored in the Internet address memory 10 together with information indicating programs and pages related to the Internet address memory 10. After performing the processing for this, the process returns to the original routine. If it is determined in step F104 that the data is not the address data of the Web site, that is, it is normal teletext data, the process proceeds to step F106 to store the teletext data in the teletext data memory 7. To be. By repeating such processing operations, text broadcast data and the accompanying Web are converted from the received video signal.
It becomes possible to extract and store the address data of the site b.

Next, the processing operation of the controller 8 for registering the address data of the Web site in the address list when the teletext screen is displayed will be described with reference to FIG. In this routine, a control processing operation for displaying a teletext page of a program designated by the user in step F201 is performed, and in the next step F202, as described with reference to FIG. It is determined whether or not an operation for registering the address of the Web site displayed as “<” is performed. Here, if the address registration operation is not performed, the process proceeds to step F204, and it is determined whether or not an operation to access the Web site of the address of the Internet address display 24 has been performed. If it is determined in this step that the operation for access is not performed, the routine is reentered from the original routine to execute the process of step F201, and the operation of the address registration and the display of the Web site being displayed are performed. Wait for operation for access. On the other hand, the above step F204
When it is determined that the access operation to the displayed Web site has been performed in the above, the address data of the Web site currently displayed as the Internet address display 24 is read from the area of the Internet address memory 10 and the internal data is read. Processing for writing to the address list area 10a is performed. As a result, as described with reference to FIG. 3, the address data of the Internet address display 24 is automatically registered as an address list. When the process of step F205 is executed, the process proceeds to the process of step F303 in FIG. 7 described below, and access to the Web site is performed.

If it is determined in step F202 that the address registration operation has been performed, the process proceeds to step F20.
The process proceeds to step 3 in which the address data of the Web site currently displayed as the Internet address display 24 is read from the area of the Internet address memory 10 and written into the internal address list area 10a. Thus, the address of the Web site is registered based on the operation of the user.

FIG. 7 shows the processing operation for accessing the Web site of the address selected by the user from the address list display screen shown in FIG. As the processing operation shown in FIG.

First, in step F301, processing for displaying an address list as shown in FIG. 4 is performed, and in the next step F302, it is determined whether or not an address designation operation has been performed. Here, if it is determined that there is no address designation operation described with reference to FIG. 4, the process proceeds to step F308, and it is determined whether an operation for terminating the address list display has been performed. If it is determined in step F308 that there is no operation for terminating the address list display, the process returns to step F302 and waits for an address designation operation. On the other hand, if an operation for terminating the address list display is performed, the process proceeds to step F309 to terminate the address list display that has been displayed so far, and instead displays the address list display before the address list display. The display is switched to the previous image display, and the process returns to the original routine. That is, according to the display state before the address list is displayed, the screen is switched to a normal television broadcast screen, a text broadcast screen, or an Internet browser screen.

If it is determined in step F302 that an address designation operation has been performed, the flow advances to step F303 to execute control for switching to an Internet browser screen. As described above, steps F303 to F3
The process 07 is performed by the browser controller 9b, and when the previous process is executed by the controller 8 (that is, when the mode is a mode for displaying a text broadcast or a normal television broadcast). The processing after step F303 is taken over by the browser controller 9b. Also, the processing after step F303 is
Step F205 of the flowchart of FIG. 6 described above.
This is also the processing that follows.

In the next step F304, a process of automatically inputting the address specified in step F302 as the address of the Web site to be accessed by the browser software is performed, and based on this, the address input in the next step F305 is performed. Control for accessing the Web site at the address is executed. Then, step F3
At 06, a process of importing the accessed Web site data into the Internet connection unit 9 is performed, and at step F307, control for displaying on the display device 13 is executed based on the imported Web site data.

It should be noted that the present invention is not limited to the configuration of the embodiment described above, but can be changed in accordance with actual use conditions and the like. In response to a program or page change, the address newly displayed as the Internet address display 24 each time is considered to be a Web site that may be of interest to the user, and may be automatically imported. Can be In the above description, the character string "http: //" is used to indicate whether the data is the address data of the Web site or the normal teletext data. For example, a predetermined header is added from the transmission side. If the address data of the Web site is transmitted, the address data of the Web site can be identified using the header. In the above description, the address of the Web site having the detailed information of the teletext program independent of the television broadcast is transmitted.
