In particular, the present invention relates to a broadcast-type real-time hypertext communication method and a receiving apparatus for broadcasting information of main broadcast contents in real-time in a hypertext format by using a sub-channel capable of broadcasting character information.

[0002]

2. Description of the Related Art Conventionally, in FM broadcasting and TV broadcasting, so-called character broadcasting is a service in which, in addition to audio and images, which are main broadcasting, subcarriers are used and characters are included therein.
Screws are done. These teletexts include new
Information such as satellite information, weather forecasts, stock price information, etc. is posted and constantly broadcast to the user.If a radio or television equipped with this receiving function is used, it is possible to listen to this information along with the main broadcast. It is possible. On the other hand, the WWW (World Wide Web) is becoming widespread in the Internet world. This is the information (content) described in hypertext called HTML, which is supported via the Internet.
It is a system that can be accessed by anyone and can be accessed by anyone in the world. In an HTML document, not only sentences but also multimedia information such as audio and images are included in the content.
In addition to handling it by pointing to its existence (pointer or tag), you can also describe the text structure such as chapters and sections (structuring). In addition, the resources (r
It has the feature that the location of esource) can be described in a format called URL. By describing a pointer to a URL, it is possible to browse and browse from one resource to another resource in the Internet one after another.

[0003]

The WWW is a system which has been widely used in the Internet. The hypertext concept used for this is expected to be used in a wide range of fields in the future. The application to broadcasting is considered to be one of them, but in the past, the hyper
No consideration was given to incorporating the concept of text into the broadcast.

Further, conventionally, the time from what time (minutes) to what time (minutes) a desired program, for example, a song program, is recorded by a viewer using a G code or the like for broadcasting from a broadcasting station. Although it was possible to make reservations in units, it was not possible to make detailed selections such as recording only the scenes of songs in the song program and cutting off the moderator of the moderator.

In view of the above-mentioned problems of the prior art, an object of the present invention is that the viewer selects or selects the contents of the broadcast from the broadcast program more finely than before, and receives or records (records, records). Etc.) is to provide a broadcast type real-time hypertext communication method and a recording device. Another object of the present invention is to

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the drawings. The present invention focuses on introducing the concept of hypertext into broadcasting in order to achieve the above-mentioned object. When trying to apply the concept of hypertext to broadcasting, the following problems (1) to (4) are thought to exist.

(1) Establishment of main broadcast transmission system In broadcast, the main broadcast transmission system has already been established regardless of whether it is voice or image + sound. Is difficult to handle at
Above all, existing listeners may be adversely affected.

(2) In unidirectional broadcasting, information is transmitted in one direction from the broadcasting station to the listener. However, the WWW is interactive, and the hypertext information is provided by the server at the request of the user. For this reason,
The recipient cannot request the desired URL from the server. The VOD (which is currently under consideration)
Video-on-demand) is an attempt to interactively provide contents by providing an upstream transmission path required by the server.

(3) Ensuring real-time property The WWW has a real-time (real-time) property such as when the information is provided for the first time in response to the user's request as described above. Is not secured. Broadcasting is real-time transmission without interruption, and this point needs to be taken into consideration. Specifically, it is required that you start listening from the middle of the session or that it is okay to cut off the middle.

(4) Asynchronism between broadcasting on main communication channel and broadcasting on sub-communication channel Information is provided through the sub-communication channel in the hypertext, but in the current teletext, only text information is sent. , Strictly speaking, it is difficult to indicate (synchronize) whether the text corresponds to the main broadcast and, if so, where it corresponds.

The present invention has solved these problems, and one embodiment of the present invention will be described below. Figure 1
It is a figure which shows the relationship between the broadcasting station and receiver which took FM broadcasting as an example. The present invention is not limited to FM broadcasting, and T
It can also be used for V broadcasting, data transmission, etc.

Conventionally, there is a broadcasting station that uses a sub-carrier in addition to audio that is a main broadcasting to provide a character broadcasting service in which characters are included therein.
In addition to the main broadcast, information on the content of the main broadcast is broadcast in real time in the form of hypertext format. The radio wave emitted from the broadcasting station 1 reaches the antenna 3 of the teletext receiving radio 4 through the communication path 2. The communication path 2 includes a main communication path for broadcasting the main contents of broadcasting and a sub-communication path for broadcasting the character information expressed in the hypertext format.

The broadcast contents of the sub-communication path, which is the main part of this embodiment, will be described with reference to FIG. In the figure, the left column shows an example of the main broadcast, and the right column shows an example of the sub-broadcast of the character information in which the information of the content of the main broadcast is expressed in a hypertext format in real time. In the main broadcast, for example, "This is the broadcast station" MOC
When the announcer broadcasts "K5".
Correspondingly, in hypertext description, for example, "<S
TATION = "MOCK5"; MESSAGE = "The message from TOKYO">#
The sub-broadcast of the character information represented by "is broadcast. This character information indicates that “the broadcasting station is“ MOCK5 ”and the catchphrase is“ The message from TOKYO ””. The "#" at the end indicates that the events in <> described above are currently continuing.

Next sub-broadcast "<TIME =" 20:45:50 "; TZONE ="
JST ">@" indicates that the current time is Japan time 20:45:50. The "@" at the end indicates that the events in <> occur when this mark is sent. ""
By using @ ","#"", it is possible to secure the synchronization between the contents of the sub-channel and the contents of the main channel. At this time, for example, on the main communication path, a message such as "The time has now become 20:45:50" is being made.

[<< TIME = "21:00:00"; TZONE of the next sub-broadcast
"=" JST "><PROGRAM=" 79.5MHz: //MK5.100106 ">>@"
"The time is 21:00 and it indicates that the program identified by MK5.100106 starts broadcasting. The above-mentioned"<PROGRAM = "79.5MHz: //MK5.100106">"is the program The program name is indicated by a name or number, and its broadcasting frequency or channel is indicated at the beginning, which means the start of the program. Also here, the form <<time><program>> @ appears, but this means that multiple hypertext units can be written in <> preceding @, and these multiple events cause @ to be sent. It means that it will occur at some point. The above hypertext description is just an example,
It does not indicate that the description method is limited to this content. The same applies to the following.

Next, another embodiment of the present invention will be described with reference to FIG. This embodiment is an example in which the broadcasting station MOCK5 plays a music program as a main broadcast from 21:00.

The first sub-broadcast, "<STATION =" MOCK5 "; MESSA
GE = "The message from TOKYO">#"is the same as above. Next sub-broadcast "<TIME =" 21:00:00 "; TZONE =" JST ">"
Is the same as described above. In addition, "<PROGRAM =" of the next sub broadcast.
79.5MHz: //MK5.100106 ">; PROG NAME ="Today's research ", ATTR
IB = "MUSIC", MESSAGE = "That song that touches my heart", LANG = "Japane
se ", REF =" http: //WWW,mock5.co.jp/MK5.100106 ">"
“The program“ Today's Research ”identified by MK5.1001 will start. Music“ A heartwarming song ”will start, the language is Japanese, and the reference URL is“ http: //WWW,mock5.co.jp/MK5. .
It means "is 100106".

Next, "<MUSIC =" MOCK5.AA1021 "; TITLE ="
"Tsunanai", ATTRIB = "ENKA", PLAYER = "Tere Satin"> @ "
Means, "The music" tsugunai "identified by MOCK5.AA1021 starts, Jianru is" enka "and the singer is" tele satin "". Next, "<\ MUSIC
"MOCK5.AA1021"; TITLE = "Tsunai"> @ "is" MOC
K5. It means the music "endless" end identified by AA1021. Here, "\" is a character indicating the end.

The description of the next song "Yuzuki" is the same as the above-mentioned song "Tsugunai". Next, "<\ PROGRAM =" 79.5MH
z: //MK5.100106 ">@" means "Program MK5.100106
“End”.

Next, an embodiment of the receiver of the present invention will be described. FIG. 4 is a block diagram showing the configuration of the receiver. In this figure, the same reference numerals as in FIG. 1 indicate the same or equivalent parts. This embodiment shows the configuration of the receiving side that receives the sub information of the above-described hypertext description according to the present invention in an FM broadcast that broadcasts a text broadcast as a sub broadcast.

The receiving side is composed of a teletext receiving radio 4 capable of receiving a broadcast wave from a broadcasting station and outputting a main broadcast audio signal and sub information data, a personal computer (hereinafter referred to as a PC). 5, a large capacity hard disk 6, a monitor 7, a mouse 8 and a speaker 9. The teletext receiving radio 4 outputs the main broadcast audio output and data output to the PC 5.

The PC 5 has an audio signal input section 51 and an audio signal output section 52 which are composed of normal hardware and have an audio signal input / output function. Further, as software, a compression / format conversion unit 53 that compresses an input audio signal and performs format conversion on the operating system, and conversely, an expansion / format conversion unit 54 that expands compressed audio signal data and performs format conversion. ,
In addition to the HTML browser 55, which is a general-purpose function of the HTML browser for the WWW system, an input data analysis / HTML generation unit 56 provided for realizing the function of the present invention.
have.

Next, the operation of this embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing an outline of the operation of the input data analysis / HTML generation unit 56.

First of all, the user can select the HT according to his / her preference.
Data for discriminating criteria such as a program to be listened to and a genre for generating the ML are created and stored in the hard disk 6. Therefore, the input data analysis / HTML generation unit 56
In step S1, the discrimination criterion data is read from the hard disk 6 to obtain the selection criterion a. In the example of FIG. 5, the genre “Enka” is set as the selection criterion in the program “Today's investigation” on the broadcasting station MOCK5. In addition, the program “traffic information” and the program “weather forecast” are set as selection criteria.

Next, in step S2, an initial template b is created on the basis of this discrimination criterion a and stored in the hard disk 6. This is an HTML framework file that has no content yet. For example, in the example of the initial template b in FIG. 6, <HTML><HEAD><TIT
LE> Mock5 Music </ TITLE></HEAD><BODY><P><H1>Today's research </ H1><H2> Recorded Enka </ H2><H3><OL></OL><HR><OL><L1>
<A HREF=""> Latest traffic information </A><L1><AHREF=""> Latest weather forecast </A></OL><H / 3></BODY></HTML> Is. This template is stored on the hard disk 6 under the name Hypertext.html, for example.

In step S3, a mouse click or the like is performed, and it is determined whether or not there is an external generation end request. If this determination is affirmative, the process ends. On the contrary, in the case of negative, the processing proceeds to step S4.

In step S4, the input data tag supplied from the sub information is read. In step S5, if data that matches the selection criterion a comes in the tag (Yes in step S5), the process proceeds to step S6, in which the file name and the entity c of the file having the file name are generated. The corresponding contents are additionally written in the template stored in the hard disk 6.

In this example, first, <MUSIC = "MOCK5.AA10
21 "; TITLE =" Tsunai ", ATTRIB =" ENKA ", PLAYER =" Telesatin "> @ matches the selection criteria, so the file name: AA102
Create a 1.ra file on the hard disk audio / AA1021.ra and write this file name information in the template. Here, in addition to the basic file, PLAYER information "Telesatin" is added to the template together. FIG. 7 shows the template at the time when this processing is completed. In FIG. 7, the latest traffic information and the latest weather information are added to the template.

In step S7, input data analysis / HT
The ML generation unit 56 issues an instruction d to the compression / format conversion unit 53 to start compression and format conversion of the audio signal from the audio signal input unit 51. The compressed audio signal data e processed according to the instruction d is output to the file audio / AA1021.ra in the hard disk 6. As software for performing this compression / format conversion, for example, RealAudio En from Progressive Networks, Inc.
There is a coder.

In step S8, input data analysis / HT
During this period, the ML generation unit 56 continues to read the input data tag, and the end tag <\ MUSIC = "MOCK5.AA1021"; TIT
Wait for LE = "Tsunai"> @ to come. Step S9
When the end of the content is detected, the compression format conversion is stopped when the end of the detection is detected, and step S
At 10, the file is closed.

Next, returning to step S3, it is again judged whether or not there is a generation end request from the outside. When this determination is negative, the processing of steps S4 to S10 is repeated. Finally, when the determination in step S3 is affirmative,
The process ends.

FIG. 8 shows an example of the sub information data broadcast from the broadcasting station 1 and an example of an HTML file generated by the HTML generation processing of FIG. 5 for the sub information data. In addition to this, the most recently broadcast traffic information and weather forecast information are additionally generated.

Next, the HTM generated as described above
The operation of reproducing the L file will be described with reference to FIG. In step S20, the user requests the reproduction f from the mouse 8 or the like.
do. This reproduction request f is instructed from the HTML browser 55 to the hard disk 6. In step S21,
According to this instruction, the HTML from the hard disk 6
The file (template file) g is read.
In step S22, the HTML file g is HTML
It is input to the browser 55, converted into display information h by the HTML browser 55, and displayed on the monitor 7.
An example of the HTML browser 55 is Netsca, for example.
There is Netscape Navigator from pe.

Hypertext. Using the Netscape Navigator
FIG. 10 shows a display example when html is read. Figure 10
In the display of, the title "Today's research", the title and singer name of the recorded enka, and the latest traffic information and the latest weather forecast are displayed.

In step S23, the user clicks the desired song, traffic information or weather forecast displayed on the monitor 7 with the mouse or the like. Then, step S
In step 24, the HTML browser 55 makes a reproduction request f for the data of the clicked subject. According to the reproduction request f, the hard disk 6 reads out the target resource and sends the compressed audio signal data i to the decompression / format conversion unit 54. In step S25, the decompression / format conversion unit 54 decompresses the compressed audio signal data i, converts the format, and sends the compressed audio signal data i to the audio signal output unit 52. As a result, music, traffic information or weather forecast is reproduced from the speaker 9.

For example, the user may say "unlucky" on FIG.
HTML is clicked by clicking the part (displayed in blue)
Browser 55 is the target resource audio / AA1021.ra
Take out the file and automatically input the file into the playback software to play the desired song. Decompression / format conversion unit 5 for decompressing the compressed audio signal data i described above.
4 software is, for example, from Progressive Networks
RealAudio and so on.

As described above, according to this embodiment, if the user registers the genre of the program to be recorded in the template of FIG. 6, the program of the genre is automatically selected from the broadcast, It can be recorded in a hypertext description on a storage medium such as a hard disk. Further, according to this embodiment, since the broadcast program is recorded in the hypertext description, it can be freely reproduced by the HTML browser. In addition, if the access number of the Internet homepage is entered in the sub-broadcast from the broadcast station, the user can obtain more detailed data about the broadcast by accessing the homepage of the broadcast station from his browser. become able to. Further, if the related program information is included in the hypertext description during the sub-broadcast, the user can automatically access and record the related programs one after another.

In the above embodiment, the identifier of the content of the hypertext in the sub-broadcast is interpreted, only the content of the main broadcast that matches the discrimination reference data is transmitted, and the transmitted main broadcast is temporarily stored in the hard disk. However, the transmitted main broadcast may be directly transmitted to the audio signal output unit 52 and reproduced from the speaker 9 without being recorded in the hard disk. If you do this,
Normally, it is possible to listen to a favorite CD or the like, interrupt the CD or the like when a desired program is started, and play the contents of the main broadcast through a speaker.

As described above, when the present invention is applied,
By adding identification information in real time to broadcasts that used to send information only in one direction,
While the listener can select and listen to the program, and organize it adaptively,
It becomes possible to record and record programs. Further, since this identifier can be defined as an extension of the existing WWW, the WWW service of the Internet and the broadcasting can be integrated.

[0043]

As described above, according to the present invention,
The following effects can be expected. (1) According to the inventions of claims 1 to 3, the identification information can be added in real time to the information of the content of the main broadcast, and the information can be broadcast in the hypertext format.

(2) According to the invention of claim 4, according to the description of the sub broadcast, it is possible to selectively receive the main broadcast, that is, to perform so-called filtering. For example, a listener can usually listen to a favorite CD or the like, but the receiver can interrupt the CD when the traffic information is started and play the content of the main broadcast on the speaker. Also, the main broadcast can be automatically played to the speaker in the event of a disaster.

(3) According to the inventions of claims 5 to 8, a program of a genre registered in advance by the user is automatically selected from the broadcast and recorded in a storage medium such as a hard disk in a hypertext description. Will be able to. Unnecessary information such as advertisements and talks by the moderator can be automatically cut. In addition, since the broadcast program is recorded in the hypertext description, a general-purpose HT
It can be played back freely by using an ML browser or the like.

(4) According to the inventions of claims 5 to 8, it is possible to successfully capture the information content of the sub-broadcast into the computer. For example, if the contents of weather forecast / traffic information / news etc. are also sent to the sub broadcast together with the identifier, the personal computer can selectively record and organize them. It is also possible to automatically create a database of the contents for one year. Further, in the past, it was a problem to publicize the contact information of advertisements with applications such as sweepstakes. However, if the present invention is used, the destination (address, telephone, fax, WWW server address)
You can record the contents of the prize application (quiz content, recipients, how to know the winning result, etc.) on your computer so that you can search later.

(5) According to the invention of claim 2 or 9, for example, the WWW address in which detailed information such as a singer or a group is described is included in the song of the sub-broadcast. If you have a song that you have access to,
It is possible to obtain unlimited information such as CD information and concert information (improvement of promotion ability). Also,
In addition to distinguishing received information from the broadcast news and weather forecast according to its contents, it also automatically interprets references to other programs pointed to in the program, and the listener records the reference program.・ Links can be adaptively created. For example, if you refer to a special program in the hypertext news, this program will also be automatically recorded,
The listener can later read the news from the personal computer and, if necessary, click the mouse to listen to the special program.
