BEST MODE FOR CARRYING OUT THE INVENTION <First Embodiment> FIG. 1 is a block diagram showing a configuration of a broadcasting system according to an embodiment of the present invention. Hereinafter, the same parts are designated by the same reference numerals.

The broadcasting system comprises a program creation station 1 and a transmission station 2.
And a receiving device 3, and a monitor 4 is connected to the receiving device 3.

In the first embodiment, the configuration of the digital broadcasting system will be described.

The receiving device 3 receives a digital broadcast from the outside, for example, an image signal compressed by MPEG2, and as shown in FIG. 1, a reception demodulator 11, a display screen synthesizer 12, a controller 13 and an information table. Extractor 14,
It has a demultiplexer 16, an audio decoder 17, a video decoder 18, and an EPG screen synthesizer 19. This is similar to the example of the conventional digital broadcast receiving apparatus. In addition to this, in the present embodiment, a character information extractor 20 that extracts character information from an information table or program data, an address information acquisition device 21 that further extracts URL address information from the extracted character information, are extracted. It has a memory 22 for storing a URL address and a browser 24 for displaying a home page screen of the selected URL address.

The operation of the digital broadcast receiving system will be described below. The reception device 3 first demodulates the received digital broadcast signal by the reception demodulation unit 11. The information table extractor 14 conforms to the MPEG2 system, and is an information table regarding each program of each channel multiplexed and transmitted in a digital broadcast signal, that is, a PAT (Program Associative) that is information of the entire transmitted program.
application table, PMT (Program Mappi) that is information about the packet configuration of each program, and the like.
ng Table), EIT which is detailed information of each program
(EventInformation Table) is extracted from the digital broadcast signal. EPG screen synthesizer 1
9 informs the user of the information on the program in the signal from the table information. For example, the EPG program guide can be constructed by reconstructing the information in the table. The monitor 4 presents the information to the user.

In addition to the EPG, the above information is used for data broadcasting, text broadcasting data, control for recording / reproducing of recording equipment, and the like.

When the user designates a specific program, the controller 13 instructs the demultiplexer 16 to select the packet of the digital broadcast signal received from the reception demodulation unit 11 based on the table information. According to the instruction, the demultiplexer 16 sends the audio data bit stream and the video data bit stream to the audio decoder 17 and the video decoder 18 while disassembling the packet format. The audio decoder 17 and the video decoder 18 respectively decode the data,
Play the program on the monitor 4.

The character information extractor 20 inputs the information table from the information table extractor 14 and extracts the character information put in a predetermined format for constructing the EPG or the like from the information table such as the EIT. Also, input private data of a predetermined format from the demultiplexer 16,
From there, character information used for program description and closed captions is extracted.

The address information acquisition unit 21 determines "http" from the character information extracted by the character information extraction unit 20.
Characteristic character strings such as “www” and “@” and combinations thereof are discriminated to extract URL address information.

In addition to the above, a predetermined format, for example, a character string such as "UC = ***" is extracted. The controller 13 has a conversion table as shown in FIG.
When a character string of a predetermined format as described above is detected, "http: //: //www.**.
*. com "automatically. By setting and using a character string that has undergone such a shortened form or compression conversion, it is possible to reduce the transmission capacity and the memory amount.

The extracted URL address is sent to and stored in the memory 22 in the state of the character string as it is or in the state of the abbreviated conversion as described above.

The controller 13 accesses the home page of the extracted URL address, acquires a part of the data, and stores it in the memory 22. As a result, when the user selects to display this home page, the time for starting display is shortened.

Further, when the URL address in the broadcast data does not include a title, the title of the homepage is acquired and stored and displayed together with the URL address, which facilitates the user's selection. In addition, it is possible to determine whether the home page is currently valid depending on whether the data can be acquired.

When it is invalid because it is not currently connected to the Internet, the information "temporarily invalid" and the valid time for reacquisition are stored together, and when reconnecting within the valid time. Then, the information that is "temporarily invalid" is acquired.

If the home page is not available due to the fact that there is no corresponding home page despite being connected to the Internet, information indicating that the home page is currently invalid is also stored or deleted from the memory 22 because it is invalid. To do.

Data of valid homepage is browser 2
Sent to 4. The browser 24 creates a home page screen from the input data. The decoding screen, the EPG screen, and the home page screen are displayed on the monitor 4 by the display screen synthesizer 12 at a preset size and position with semitransparent effects as necessary.

Next, a method of multiplexing URL address information in a broadcast signal will be described.

In digital broadcasting, the program making station 1 MPEG-encodes a program and delivers it to the transmitting station 2, and the program making station 1 multiplexes and transmits, or the transmitting station 2 is delivered from the program making station 1. There are two types, that is, whether the program is MPEG-encoded and broadcast.

In the former case, when the encoder of the program making station 1 or the encoder of the transmitting station 2 encodes, the URL address is input as character information in the digital data of the program.

In the latter case, when the multiplexer of the transmitting station 2 multiplexes each program, the URL address is input as character information in the information table. The method of multiplexing the character information itself is the conventional closed caption or EP.
This can be realized by a method similar to the method of multiplexing G information.

To multiplex URL addresses earlier than the screen actually displayed by a predetermined time required for extracting character information or acquiring homepage information, or to multiplex URL addresses in program reservation information. Thereby, the homepage information can be acquired and stored in advance, and the time to start displaying can be shortened.

As described above, the browser is displayed on the screen at the same time that the information about the homepage is found by the address information acquisition unit 21, but the user says "I want to see the information related to the current screen" and the button of the predetermined remote controller. It is also possible to operate by receiving an instruction such as. In this case, it is possible to start acquiring information such as a URL address after receiving the instruction, but the reaction will be faster if the information is acquired in advance and then displayed when the instruction is received.

Alternatively, the program creation station 1 or the transmission station 2 can add the display time information to the URL address and multiplex it into the broadcast signal to display the home page at a designated timing. Address information acquisition unit 21
If the timing of displaying the address together with the URL address is multiplexed in a predetermined format, for example, in the form of an information table describing time, this display time information is also acquired and stored in the memory 22. To do. The controller 13 inputs to the browser 24 the address information in which the current time matches the stored time and the actual data of the address.

Alternatively, the actual data of the address may be displayed by the browser 24 triggered by the change of the address information regarding the corresponding program. As a result, the viewer can enjoy the change in the home page that is more closely linked to the change in the content of the program and the CM. This is the U just before stored in the memory 22 in the address information acquisition unit 21.
This can be realized by providing a function of comparing the RL address with the currently extracted URL address, or by the controller detecting the change of the program itself currently being viewed from the user's operation or table information.

With the above configuration, it is possible to display the displayed screen and the homepage screen linked to the program contents together with the TV screen.

Further, by temporarily storing the URL address and homepage data in the memory 22, a user watching a TV broadcast program can view the related homepage later or look back on the previous related information. , It is possible to select from multiple candidates.

When the "URL history" button provided on the remote control or the GUI on the TV is pressed, the controller 13 reads the URL list information stored in the memory 22 and inputs it to the browser 24. Browser 24 is the URL entered
A homepage screen is generated from the list information, and the recent URL history as shown in FIG. 5 is displayed on the monitor 4. By selecting this with the up and down keys, etc., it is possible to select and view from the homepages recently viewed or the homepages automatically obtained in conjunction with the program contents. At this time, by also storing the update date and time of the homepage, if the display designation is performed again for the page that was previously displayed, check the update date and time and if it has not been updated from the previous display Can display "not updated". As a result, it is not necessary to acquire the entire data when accessing a home page that is regularly patroled or accessed once again, and it is possible to reduce user browsing time and data communication volume. it can.

Although the controller 13 performs the conversion illustrated in FIG. 4, it may be performed at an external site.

The controller 13 sends the extracted shortened character string to the conversion site 6 shown in FIG. 3 in a predetermined format. The conversion site 6 determines by the determination means 61 based on whether or not a predetermined character string is present in the request that the search request is from the receiving device 3. The character string conversion means 63 performs conversion based on the conversion table shown in FIG. 4, and returns the result.

As compared with the case where conversion is performed within the main body of the receiving device 3, there is an advantage that the size of the conversion table can be increased and the contents can be set and updated more flexibly. Due to the large size of the conversion table, it is possible to replace the URL address with a shorter character string such as a number.

Although the URL address and the time information are stored in the memory 22 in an independent form, the data format for storing them is arbitrary. For example, MPEG2-T.
It may be converted into the format of the S table information and stored. Further, these pieces of information converted into the form of table information may be multiplexed again with the MPEG2-TS signal of the corresponding program and recorded or output.

The format of the abbreviated character string is not limited to the one illustrated in FIG. 4, but any format which can be extracted by the address information acquisition device 21 and is shorter than the original character string can be adopted.

<Second Embodiment> As a second embodiment, a case of analog broadcasting will be described.

The receiving device 3a receives an analog TV broadcast from the outside. As shown in FIG. 2, the receiving demodulator 31, the display screen synthesizer 12, the video / audio separation converter 32,
Controller 33, closed caption generator 3
4, EPG screen synthesizer 35, and a character information extractor 40 for extracting character information. This is similar to the example of the conventional analog broadcast receiving device. In addition to this in the present embodiment,
It has an address information acquisition unit 21 for further extracting URL address information from the extracted character information, a memory 22 for storing the extracted URL address, and a browser 24 for displaying a home page screen of the selected URL address. .

The operation of the broadcast receiving system will be described below.

When the user specifies a particular channel,
The reception device 3a first demodulates the received analog broadcast signal by the reception demodulation unit 31. The EPG screen synthesizer 35 extracts the program guide information from the VBI signal of the broadcast signal and reconstructs it to generate an EPG program guide. In some cases, closed captions and character information of character multiplex broadcasting are also multiplexed in the VBI. The character information extractor 40 extracts such character information.

Similarly, the address information acquisition device 21 determines characteristic character strings such as "http", "www", "@" and the like from the character information and extracts the URL address information.

After that, the process of generating the home page screen of the extracted URL address is similar to that of the first embodiment. Broadcast screen, EPG screen, closed caption,
The home page screen is displayed on the monitor 4 by the display screen synthesizer 12 with effects such as preset size, position, and translucency.

With the above configuration, it is possible to display the displayed screen and the homepage screen linked to the program contents together with the TV screen.

In analog broadcasting, the program creating station 1 modulates a program and multiplexes EPG information and character information created in advance when transmitting the program.

<Third Embodiment> As a third embodiment, an operation when the URL address does not exist in the character information will be described.

The controller 13 uses the words in the character information extracted by the character information extractor 20 as keywords.
Search for related homepages. In the memory 22,
Genres such as “news”, “variety”, and “sports” and keywords that frequently appear in programs of each genre and are easy to pull out relevant information are stored in the memory 22 in advance. For example, in “news”, the names of ministries and agencies, companies, places, and sports, the names of sports, teams, positions, etc. are stored as keywords. Controller 1
3 also stores the keyword input by the user in the memory 22.

If a word of character information is tagged with a predetermined degree of importance, the controller 1
3 extracts as a keyword a word with a tag indicating that the degree of importance is high. Also, the EPG in the information table
When the genre of the program currently being viewed is described in a predetermined format such as the purpose of use, it is treated as a keyword of high importance.

The controller 13 sends the keyword to the preset search site 7 and extracts the higher address from the returned search results. The search site determines by the determining means 71 that the search request is from the receiving device 3 based on the fact that a predetermined character string is present in the search request.

When the search site determines that it is a search request from the receiving device, it further narrows down the normal search results. To narrow down, have a tag that indicates "compatible with size and style suitable for display on receiver", "Do not include special effects that cannot be displayed on receiver", sexual description Do not include or depiction of violence, etc., and make sure that the page under the site of the program broadcasting station is placed higher. For example, a tag that indicates "corresponds to a size and style suitable for display on the receiver" is <! TV DISPLAY> etc. indicates that a specific tag that does not adversely affect others is set.

The search result is delivered to the receiver via the Internet. The narrowing down according to the receiver eliminates the need for the user to select from a huge number of candidate pages as in the conventional search, and the probability that a page more suitable for display on the TV monitor than the conventional search is selected. Will increase.

In the memory 22, the URL address of the previously selected home page is also stored together with the retrieved URL address. The controller 13 is a keyword of the retrieved address, a genre information and a stored keyword, a stored homepage keyword,
Compare with genre information and select homepages with many matching items as candidates.

The controller 13 uses each URL address, title, or part of the data stored in the memory 22 to generate a selection screen and displays it on the monitor 4. When the user looks at the selection screen and selects a certain item,
The controller 13 is the URL corresponding to the selected item
Enter the address into the browser 24. The selection screen may be omitted and the highest-ranked candidate may be sent directly to the browser 24. Further, the user may be allowed to input a search character string in order to narrow down more accurately.

By the above method, even when the related URL address is not multiplexed in the TV signal, the genre or keyword of the program currently being viewed is acquired from the character string in the table information, and based on that, You can display the linked homepage by searching on the Internet.

It is also conceivable that the search site 7 receives a reward from the sponsor and sets the returned address information in the higher rank of the search results. As shown in FIG. 3, the search site 7 sets the address information designated by the sponsor at a higher rank in the search order. Further, only when the determining means 71 determines that the access is from the receiving device 3, the search result can be returned. By this method, the sponsor can effectively transmit information to a specific model, a specific receiver, etc., and the search site gets a reward for it.
These rewards may be fixedly set, such as one page per month, or calculated based on the counting result of the counting means 72.

Further, even when there is no particular related character information, the receiving device 3 may periodically access. In this case, the search site 7 displays “the receiving device 3
Access from ", no specific search string"
In such a condition, general information such as "news", "weather", "traffic" and information such as commercials are returned.
At this time, it is also possible to return the regional information by using the positional information set when the receiving device 3 is installed, such as a postal code, as a condition.

As a result, the user who is watching the television receiver can obtain information related to life without particularly positively requesting it.

<Fourth Embodiment> As a fourth embodiment, an operation example including a website will be shown.

FIG. 3 shows an example of operation using the system of FIG.

In this system, the address information is T
The website 5 that has sent out the V broadcast signal distinguishes the access from the receiving device incorporating this system from the browsing from other terminals by the determination means 51. The terminal can be distinguished from other terminals by a method such as determination by transmitting and receiving predetermined data. The counting means 52 counts the number of accesses from the receiving device incorporating this system. The reward calculation means 53 determines the number of times the Internet is accessed.
The advertisement fee is calculated as a reward. The owner of each Internet homepage pays the calculated advertising fee to the transmitting station. This system can also be applied to the analog broadcasting system shown in FIG.

The user watching the TV can easily access the related homepage, and the Web site has an advantage that the number of accesses from the TV having many viewers can be increased. With the above configuration, T
It is possible to reliably reflect the increased number of accesses from V and pay the broadcaster.
