[0005]

[Problems to be Solved by the Invention]-Generally, it can be said that a program used (viewed, recorded, etc.) by a user includes an object of interest of the user, so that the program can be used later. Furthermore, it is useful for the user to store the URL included in the data broadcast as described above. On the other hand, when viewing a broadcast program, unlike when browsing a homepage on the Internet, there are many cases where the content is not watched. Conversely, it can be said to be a good point of a broadcast program. Given that broadcast programs may make this use, simply storing all of the URLs associated with the program that the user has watched is only possible if the user subsequently searches for it. It is complicated.

[0006] Also, one program has a lot of related information depending on the scenes and scenes, and in some cases, scenes / information which is not interesting to the user is included. Is not very efficient in terms of both the storage capacity of the information processing apparatus and when the user subsequently searches for them.

An object of the present invention is to enable a user to efficiently search for a network address contained in a television broadcast signal when the user later searches for a desired network address.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings. First, analog television broadcast reception will be described. As shown in FIG. 1, in an information processing apparatus (analog television broadcast receiving apparatus) 1, an antenna 3 is transmitted by encoding and superimposing teletext data on a television signal of a television program produced by a broadcasting station. Teletext signal is received, and analog data broadcasting tuner 3 is received.
Extracts video and audio signals from the received signals and supplies them to the display device 6 and the speaker 6. Further, it sends the teletext signal to the decoding processing unit 22. The decryption processing unit 22
The teletext signal is converted into a video signal and an audio signal and sent to the analog data broadcasting tuner 3. If requested, it is sent to the printer device 8 or the audio device 9.

The analog data broadcasting tuner 3 will be further described. The antenna 3 receives a teletext signal transmitted by encoding and superimposing teletext data on a television signal of a television program produced by a broadcasting station. Then, the signal is supplied to the television signal receiving circuit 12. The television signal receiving circuit 12 selects a desired television signal from a plurality of television signals received by the antenna 3.
Demodulate and separate into audio and composite video signal. The composite video signal separated by the television signal receiving circuit 12 is separated and generated into a luminance signal and a chrominance signal in a luminance amplification / color demodulation circuit 17, and these are supplied to a video amplification circuit 19 via a video switching circuit 18. Is done. The video signal amplified to a predetermined signal value by the video amplification circuit 19 is reproduced by the display device 6 that displays a television screen. On the other hand, the audio signal separated by the television signal receiving circuit 12 is frequency-demodulated by the audio demodulation and amplification circuit 13 and supplied to the audio amplification circuit 15 via the audio switching circuit 14. The audio signal amplified by the audio amplification circuit 15 to a signal of a predetermined value is reproduced by the speaker 5. As described above, the portion that processes the video and audio of the program is the same as a known analog broadcast tuner.

Further, in the receiving circuit 21, a teletext signal superimposed on the composite video signal separated by the television signal receiving circuit 12 is separated and extracted, and coded data (hereinafter, referred to as "text") for each teletext data line. The teletext data is supplied to the decoding processing unit 22. Decryption processing unit 22
Performs decoding processing of various data under the control of the CPU 30.

The CPU 30 decodes teletext data based on a program stored in the ROM 24.
At this time, the CPU 30 uses the work area of the RAM 23. The CPU 30 stores the teletext data separated by the receiving circuit 21 in the data memory 26. Data memory 2
The character broadcast data stored in the ROM 6 is converted into a character broadcast display using a character signal data decoding program stored in the ROM 24 and characters and graphic characters stored in the character generator 25. The data is converted into data and stored in the display memory 29 via the display processing circuit 28.
The teletext data stored in the display memory 29 is combined with the RGB signals by the display processing circuit 28 and supplied to the video switching circuit 18. When the additional sound data is included in the teletext data, it is converted into an additional sound signal by the additional sound decoder 27 and supplied to the audio switching circuit 14.

On the other hand, when a user selects a television broadcast program from the remote controller 7 or inputs a command to switch between audio and video reproduced by the speaker 5 and the display device 6 by a user's operation,
A corresponding remote control signal is transmitted from the remote control 7 and received by the remote control receiving unit 32. The remote control signal received by the remote control receiver 32 generates a control signal for controlling the operation and processing of various circuits by the control microcomputer 33. The CPU 30 controls the decoding processing unit 22 according to the control signal. For example, the audio switching circuit 14 switches between the audio signal supplied from the additional audio decoder 27 of the decoding processing unit 22 and the audio signal supplied from the audio demodulation and amplification circuit 13, and the video switching circuit 18 performs the decoding processing. The video signal of the teletext program data supplied from the display processing circuit 28 of the section 22 and the video signal supplied from the luminance amplification / color demodulation circuit 17 are switched.

The decoding unit 22 can transmit a network address (here, a URL) extracted from teletext data to the printer 8 connected via the printer control unit 45 by a process described later. Similarly, the decoding processing unit 22 can transmit the URL extracted from the teletext data to the audio device 9 connected via the audio device control unit 46. Note that the URL is a notation for representing an object on the Internet, and is described in, for example, the HTTP protocol. Usually, when accessing the homepage with a web browser,
Used to specify the server where the content is located.

Next, a process of extracting a URL from service information data in analog log television broadcasting will be described. The flowchart of FIG. 2 shows a process in which the CPU 30 of the receiver 1 shown in FIG. 1 separates and extracts a URL from a data broadcast superimposed during a vertical blanking period of a television broadcast signal.

First, it is determined whether or not the encoded data of the received / demodulated teletext data includes the URL of the Internet site. In step S100, it is checked whether the encoded data of each page of the teletext data is composed of a combination of alphabets, numbers, dots (.), And hyphens (-). Internet Terms (R
FC: Request For Comments) specifies that a URL is composed of a combination of alphabets, numbers, dots (.), And hyphens (-).

In step S100, the encoded data is not composed of a combination of alphabets, numbers, dots (.), And hyphens (-), ie, other characters (for example, dots other than!,? If it is determined that the encoded data includes character data, the encoded data is determined to be program data of a character program, and the URL detection operation ends. Conversely, if the encoded data is composed of a combination of alphabets, numbers, dots (.), And hyphens (-), then in step S102, the character string of the encoded data starts with "http". It is determined whether or not.

If it is determined in step S102 that the encoded data is a character string starting with "http", the process proceeds to step S108. Conversely, step S102
If it is determined in step S104 that the character string does not start with "http", it is determined whether the character string includes "www" in step S104.
Is determined. If it is determined in step S104 that the character string does not include "www", the URL detection operation ends. Conversely, if it is determined that the character string includes “www”, “http: //” is added before the “www” character string in step S106.
And the process proceeds to step S108. Step S104
The reason why the processing of S106 and S106 is performed is that, in the notation of the URL, the case where "http: //" at the head is omitted may be seen.

In step S108, the end of the URL is detected. The end of the URL is a character immediately before a character other than the first alphabet, a numeral, a dot (.), And a hyphen (-) in a character string following "http". Finally, in step S323, the extracted URL is stored in the URL storage memory 41.

Next, digital television broadcast reception will be described. FIG. 3 shows an information processing device (digital television broadcast receiving device) 2. In digital television broadcasting, in addition to television systems using broadcasting satellites, it is planned to be adopted for terrestrial and cable television in the future.
Although being studied, a case where the transmission source of the digital television signal is a broadcasting satellite will be described here.

In the information processing device 2, the signal processing unit
It comprises a tuning circuit 51, a QPSK demodulator 52, a descrambler 53, a transport separator 54, an MPEG demodulator 55 and a D / A converter 56 connected to the BS antenna 4. This signal processing unit is connected via a bus 57 to a CPU 58 that controls the present apparatus. The CPU 58 is connected to an IC card 59, a RAM 60 as a work area, a ROM 61 for storing programs, data, and the like, and further connected to a URL storage memory 41, a printer control unit 45, and an audio device control unit 46.

In a digital television broadcasting system, a signal form and system conforming to the DVB (Digital Video Broadcasting) standard are adopted. When a signal transmitted according to the DVB standard is received by the BS antenna 4,
In the signal processing section, the digital television signal converted to the intermediate frequency is supplied to the channel selection circuit 51, where the channel desired by the viewer is selected and converted to a baseband signal.
The baseband signal is demodulated into digital data by a QPSK demodulator 52, and the demodulated digital data is divided into packets and supplied to a descrambler 53 as transport stream data. When the transmitted signals are encrypted, the descrambler 53 decrypts the transmitted signals and supplies the decrypted signals to the transport separator 54. The transport separator 54 separates the transport stream data into a bit stream of video data and audio data of the transmitted program from the transport stream data according to a packet separation procedure. Each separated bitstream is
It is supplied to the MPEG demodulator 55 and decoded according to the MPEG demodulation procedure. M decoded by the MPEG demodulator 55
The PEG decoded signal is converted by a D / A converter 56 from a digital signal to an analog signal. The analog signal is output to, for example, the analog TV unit 10 and reproduced / displayed.

The CPU 58 has a built-in real-time O
In accordance with the S and the system program stored in the RAM 60, the signal processing is performed via the bus 57 while performing various controls so that the signal processing units 51 to 56 can operate efficiently.

When a program received by the BS antenna 4 and tuned by the tuning circuit 51 is encrypted and transmitted,
The viewing contract information stored in the IC card 59 is transferred to the CPU.
At 58, the data is read, and the descrambler 53 is controlled to decrypt the data.

The ROM 61 stores a system program corresponding to the broadcasting satellite contracted by the user. The system program is transmitted from the CPU 58 to the ROM 61.
, And reads a system program stored in the ROM 61 into the RAM 60.
Using the system program read out to the RAM 60, the CPU 58 selects the channel selection circuit 51 of the signal processing unit, the QPS
It controls the K demodulator 52, the transport separator 54, the MPEG demodulator 55, and the D / A converter 56.

Some digital television broadcasting receivers have a plurality of ROMs 61 (for example, a first ROM and a second ROM), and different ROMs store different system programs. . In such a digital TV broadcast receiver, it is possible to switch which system program is to be operated, and it is necessary to change or newly purchase the receiver itself for digital TV broadcast services of different systems. Instead, it can be handled only by switching the system program.

The digital television broadcast receiver 2 has:
Printer device 8 connected via printer control unit 45
Then, the URL extracted from the service information data by the processing described later can be transmitted. Similarly, the digital television broadcast receiver 2 can transmit the URL extracted from the service information data to the audio device 9 connected to the information processing device 2 via the audio device control unit 46.

Next, processing for extracting a URL from service information data in digital television broadcasting will be described. As described above, the digital television broadcasting system employs a signal format and system conforming to the DVB standard. In the DVB standard, service information data of a program is provided in addition to MPEG-compressed video and audio data. Transmitted. In this service information data, for example, a program number, a program title, a program start date and time and a program length time, a current time, and detailed program information such as a story of the program and performers are transmitted in a time-division manner in a bit stream. I have. Therefore, a URL related to the contents of the program transmitted as the service information data is extracted and stored. The process of judging the presence of a URL from service information data and recognizing the URL is the same as in the case of analog data broadcasting shown in FIG. 3, and a repeated description is omitted here.

As described above, in analog television broadcasting and digital television broadcasting, UR
The process of extracting L has been described. Thus, U
Regarding RL, the CPUs 30 and 58, which are control units, can perform various processes for the convenience of the user, as described below.

In the first embodiment of the present invention, how the user has used the received program is detected, and the URLs extracted by the extracting means are classified and stored according to the detected usage mode. . Therefore, depending on how the user used the program, a network address (here, an Internet site address) that provides information related to the program received in those programs.
Are classified and stored, so that the user can efficiently search for a desired URL later.

In this processing, the user extracts the URL extracted from either the teletext data superimposed during the vertical blanking period of the analog data broadcast or the service information data in the digital television broadcast, and determines which program Thus, the program is classified and stored in accordance with the type of use of the program, that is, the use form of the program. Here, the URL information is classified according to three usage patterns and stored in the URL storage memory 41. As shown in FIG. 4, the URL storage memory 41
Is divided into three areas (a first URL storage area 410, a second URL storage area 412, and a third URL storage area 414) according to the above three usage patterns. Examples of the use form of a program include (1) when the program is recorded, (2) when the program is viewed as a main screen of a two-split screen, and (3) when the program is viewed as a sub-screen of a two-split screen. In this case, use. URL taken from the program being recorded
Is stored in the first URL storage area 410. URL extracted from the program viewed as the main screen of the split screen
Is stored in the second URL storage area 412. URL extracted from the program viewed as the sub-screen of the split screen
Is stored in the third URL storage area 414.

FIG. 5 shows a flow of processing of the CPUs 30 and 58 for classifying and storing URLs according to the use form. First, the URL detection process shown in FIG. 2 is performed (S12).
0). Next, the use mode is determined. If the program is recorded (YES in S122), the first storage area 41
The URL is stored in 0 (S124). If the program is viewing the main screen of a two-split screen (or as one non-split screen) (YES in S126), the second storage area 41
The URL is stored in No. 2 (S128). If the program is viewed on the sub-screen of the split screen (YES in S130),
The URL is stored in the third storage area 414 (S13
2).

Preferably, means for designating a use form is further provided, and a URL of a program used in the designated form is provided.
Just select and remember. Since only the address of an Internet site that provides information related to a program used in a use mode specified in advance by the user is stored, the user can efficiently search for a desired URL later. Specifically, on the remote controller 7, a “store URL at recording” button, a “store two-screen main screen URL” button, and a “store two-screen sub-screen URL” button are provided.
(Neither is shown). The user presses any one of these buttons to specify a use mode for storing the URL. In this case, in the processing of FIG. 5, in the determinations of steps S122, S126, and S130, it may be determined that the usage mode by pressing the button is also selected. The above-described processing can also be executed by displaying function buttons corresponding to these buttons on the display device and pressing the buttons by the user.

In the second embodiment of the present invention, how the user uses the received program is detected, and the extracted URL is stored in the URL storage memory 41 together with the use form information of the program. By storing information on the usage mode together with the URL, when displaying the URLs stored in the URL storage memory 41 in a list on the display device, for example, the URLs can be classified and displayed for each usage mode.
L can be searched more efficiently.

If the examples of the above three usage modes are used as they are, (1) the usage mode identification number is “1” when the program is recorded, and (2) the program is viewed as a main screen of a two-split screen. In the case, the use form identification number is “2”, and (3) the program is 2
The use mode identification number is defined as “3” when viewed as a sub-screen of a split screen. And, as shown in FIG.
In the URL storage memory 41, this usage pattern identification number is stored together with the URL.

FIG. 7 shows a processing flow of the CPUs 30 and 58 for storing a URL and a use mode identification number according to the use mode. First, the URL detection processing shown in FIG. 2 is performed (S140). Next, the use mode is determined. If the program is recorded (YES in S142), the URL and the usage mode identification number "1" are stored in the URL storage memory 41 (S144). If the program is viewing the main screen of the two-split screen (or as one non-split screen) (S14
6), the URL and the usage form identification number "2"
It is stored in the L storage memory 41 (S148). When the program is viewed on the sub-screen of the split screen (YE in S150)
S), the URL and the usage form identification number “2” are stored in the URL storage memory 41 (S132).

Preferably, means for designating a use form is further provided, and a UR of the program used in the designated form is further provided.
Only L is stored together with the use form identification number. When the user later searches for a desired URL to store the address of an Internet site that provides information related to the program together with information on how the user has used the program (usage form information) You can search efficiently.
Specifically, on the remote controller 7, a "store URL at recording" button, a "store URL for two-divided main screen" button, and a "store URL for two-divided sub-screen" button are arranged (all are not shown). The user specifies a use mode for storing the URL by pressing any of these buttons. In this case, in the processing of FIG.
46, In the determination of S150, it may be determined that the usage mode by pressing the button is selected. The above-described processing can also be executed by displaying function buttons corresponding to these buttons on the display device and pressing the buttons by the user.

In the third embodiment of the present invention, the user
When a part of a period or a scene in the received program is designated, the CPUs 30 and 58 superimpose an address (URL) of an Internet site that provides information related to the program on a vertical blanking period of the analog data broadcast. From the teletext data or the service information data in the digital television broadcast, only the time (scene) designated by the user is extracted. Then, only the extracted URL is stored in the URL storage memory 41. In this way, only the URL extracted during the period designated by the user is stored in the URL storage memory 41. Therefore, since only the address of the Internet site that provides information related to the program in the scene is stored within the period specified by the user, the storage area is not wasted and the efficiency can be improved. .

For this purpose, a "URL storage start" button and a "URL storage end" button are provided on the remote controller 7 (both are not shown). The user specifies the period for storing the URL by pressing these two buttons.
That is, when the “URL recording start” button is pressed, the CPUs 30 and 58 start recording the extracted URL in the URL storage memory 41, and when the “URL recording end” button is pressed, the In steps 1 and 2, the recording of the extracted URL in the URL storage memory 41 ends. In the description here, “URL” is displayed on the remote control 7.
The case in which the “start storage” button and the “end URL storage” button are provided has been described. However, when the function buttons corresponding to these buttons are displayed on the display device and the user presses these buttons, the above-described operation can be performed. Can perform processing.

FIG. 8 shows a CPU 3 for storing a URL in a partial period or scene of a received program designated by a user.
The flow of 0,58 is shown. UR specified by user
If it is determined that L storage has started (YES in S160), the URL detection processing shown in FIG. 2 is performed (S162). This is determined to be the end of URL storage specified by the user (S1).
Until step 60 is YES).

Next, a fourth embodiment of the present invention will be described. For example, in a printer device that forms an image on a recording medium such as paper, a technology called “Web PullPrint” that accesses a stored Internet site regularly or irregularly and prints out the homepage is generally used. Are known. Therefore, it is conceivable to use this technique by storing the URL extracted from the data broadcast or service information data in the printer device.
However, the information related to the program includes data that cannot be used by individual peripheral devices (for example, music data in the case of a printer device). Therefore, in the fourth embodiment of the present invention, the connected peripheral device and its function are identified, and the URL extracted by the extracting means is selected as the peripheral device according to the function of the identified peripheral device. To send. Therefore, since the address of the Internet site that provides information related to the program is transmitted only to the appropriate address for each peripheral device according to the function of the connected peripheral device, the peripheral device can not use unusable data. There is no need to store and download, and the processing efficiency can be improved.

FIG. 9 shows a UR corresponding to the connected peripheral device.
5 shows processing of the CPUs 30 and 58 for transmitting L to the peripheral device. Here, the URL extracted from either the character broadcast data superimposed on the vertical blanking period of the analog data broadcast or the service information data in the digital television broadcast is connected to the television broadcast receivers 1 and 2. Peripheral equipment (here, the printer device 8 shown in FIGS. 1 and 2)
And the audio device 9 as an example).

In the flow of FIG. 9, the extracted URL
First, in step S200, the extracted URL is accessed to download the html file in order to identify the data medium provided by the Internet site. Next, in step S202, an <a ref> tag is searched from the source sentence of the downloaded html file. <a href
> Search for tags in the html file, <ah>
This is because it is often specified between ref> and </a> tags. For example, in the example of the html file source shown in FIG. 10, four files (sample.pdf, sample.txt, sample.mp3, and samp) are surrounded by <a href> and </a> tags.
le.mpg) is written so that it can be downloaded.

If an <a href> tag is detected in step S204, in step S206, the detected <a href> tag is detected.
The media type of the file is identified from the extension of the file enclosed by the tag and the following </ h> tag. FIG.
In the example shown in (1), the file extensions "pdf" and "txt" indicate that the file is a document file. The file extension “mp3” indicates that the file is a music data file in the MP3 format. Furthermore, "m
The file extension "pg" indicates that it is a video file.

Next, in step S208, only an appropriate URL is transmitted to each peripheral device according to the function of the peripheral device, and the URL is stored in the peripheral device. For example,
At least the URL of the Internet site that provides the document file is transmitted to the printer device 8, and the URL of the site that does not provide the document file, for example, the URL of the site that provides only the music data, is not transmitted. This is because it does not make sense to transmit and store, for example, the URL of a site from which only music data can be downloaded, to the printer device 8 having only a function of reproducing (printing out) other than a document. For the audio device 9, at least a U of a site that provides audio data is provided.
U of site that transmits only RL and does not provide audio data
RL is not transmitted. Similarly, for example, the URL of a site that can download only a document file is stored in the audio device 9 having only a function of reproducing data other than music data.
It is meaningless to transmit and memorize.

Thereafter, the flow returns to step S202, and the next <a
href> Search for tags. If no <a href> tag can be detected in step S204 (if step S204 is “NO”), the process ends.

In the television broadcast receiver, the URL extracted from either the character broadcast data superimposed during the vertical blanking period of the analog data broadcast or the service information data in the digital television broadcast is converted into a U.S.C.
In storing the data in the RL storage memory 41, the data may be stored in advance for each connected peripheral device.

In the above embodiment, data is extracted from the site address. However, not only the site address but also a file or a path leading to the file may be extracted and classified. Although the URL is extracted, another network address such as an e-mail address for issuing e-mail news related to a program or a news group that allows browsing of e-mails from a plurality of sources regarding the program may be used.

[0053]

According to the manner in which the user used the program, the network addresses that provide information related to the program received in those programs are classified and stored, so that the user can When searching for a desired network address, the search can be performed efficiently.

In order to store a network address for providing information related to a program together with information (usage form information) on how the user has used the program,
When the user later searches for a desired network address, the search can be efficiently performed.

Since only the network address that provides the information related to the program used in the use mode specified in advance by the user is stored, the search can be efficiently performed when the user later searches for a desired network address.

Since only the network address that provides the information related to the program in the scene is stored during the period specified in advance by the user, the information processing apparatus does not wastefully consume the storage area and improve the efficiency. Can be better.

A network address for providing information related to a program is transmitted only to an appropriate address for each peripheral device according to the function of the connected peripheral device, so that the peripheral device stores data that cannot be used. Downloading is not performed, and processing efficiency can be improved.
