In such a case, the old emergency information is unnecessary information for a person who plays back the recorded video by playing back the recorded video on the TV screen by playing back the old recorded video. At times, this unnecessary display of emergency information on the screen can cause viewer confusion.

Regarding emergency information such as a disaster, information produced by a general television station is information sent to a relatively large area, but the CATV center is closer to the area due to the nature of CATV. Although information can be provided to subscribers, information closely related to the area, that is, information with strong regional characteristics, is often unnecessary for people outside the area.

Further, information with strong regional characteristics may be given from a general viewer side (CATV subscriber side), and it is expected that a concrete system for realizing this will be proposed. For example, when a fire occurs in a home that is not present, the fire is detected and automatically notified to the fire department, which is a public institution, and the CATV center also grasps the fire. Promptly, even for neighboring residents, CA
It is expected that a TV will be used to signal this.

The dedicated channel of the CATV tuner is assigned as a channel for transmitting various kinds of emergency information (fire, crime occurrence, etc.). The management center 2 of the CATV accepts reports of various emergencies from general households, public institutions such as river management centers and disaster prevention management centers, and private institutions such as security companies, and responds to the contents of the notification. The emergency video information, which is video information, is provided to the determined distribution destination using the dedicated channel.

With this, it is possible to construct a system in which the emergency information is provided as video information to a predetermined distribution destination.

The outline of the present system has been described above. The detailed processing performed by the actual CATV converter will be described below.

First, an embodiment of the present invention will be described with reference to FIGS. In this example, from a general household,
In response to the automatic notification of emergency information, the CATV center displays the transmitted emergency information as video information only on the CATV converter existing in a specific area.

FIG. 2 is a block diagram of the CATV converter 3 connected to the bidirectional digital network system 1.
The CATV converter 3 shown in FIG. 2 is mainly arranged in a general home.

The CATV converter normally operates as a CAT.
The program provided by the V management center 2 is received.

On the other hand, FIG. 3 is a block diagram of a management device provided in the CATV management center 2 connected to the bidirectional digital network network 1. The CATV management center 2 normally receives information about programs provided by TV stations, reproduced images of recorded images by video equipment, entertainment programs such as video games, karaoke, etc., public institutions such as the Ministry of Education, the Ministry of Health, City Hall, etc. , Etc. are provided by using a plurality of channels, that is, multi-channels.

In the following description and drawings,
For descriptions of functions and devices required for normal operation,
I omit it as appropriate.

Now, as shown in FIG. 2, the CATV converter 3 stores an AC controller 307 for forcibly starting up the television 500, and a notification code which is a predetermined code indicating the type of emergency. Notification code storage unit 304, area code storage unit 305 that stores an area code that is a predetermined code indicating the area where the own converter is arranged, notification signal generation unit 301, video synthesis circuit 306, television display determination unit 302 , An emergency information dedicated tuner 303, a CATV tuner 308, and a switching mechanism 309.

Further, the CATV converter 3 is connected to a fire detector 502 which detects the occurrence of a fire and outputs a detection signal. Also, through the input terminal, the video 501
Are connected, and the television 500 is connected via the output terminal. In addition, the television 500 includes the AC controller 3
07 is also connected.

The CATV converter 3 is also connected to the bidirectional digital network 1 via an interface. Further, data is sent to and received from the bidirectional digital network 1 via the transmission / reception terminal.

On the other hand, as shown in FIG. 3, the management device 2 of the CATV center includes the emergency information management device 200 and the mixer 10.
0, a clock 203, an emergency information management database 201, and an area management database 202. Also,
The emergency information management device 200 includes a notification signal receiving unit 204, an emergency information specifying unit 205, an area specifying unit 206, a distribution destination determining unit 207, and a video signal generating unit 208.

The management device 2 of the CATV center is connected to the bidirectional digital network 1 via an interface. Furthermore, via the transmission / reception terminal,
Transmission of data to the bidirectional digital network system 1,
Also, data is received from the bidirectional digital network system 1.

Now, the operation of this configuration will be described.

At the home where the CATV converter 3 is arranged,
Assume that a fire has occurred.

The fire detector 502 outputs a detection signal when detecting the occurrence of a fire.

The notification signal generator 301 is used for the fire detector 50.
When the detection signal output by 2 is input, the area code stored in the area code storage unit 305 is taken out, and the notification code stored in the notification code storage unit 304 is also taken out. The area code and the notification code are sent to the CATV management center 2 by using the digital network 1 for communication.

In the configuration example shown in FIG. 2, only the fire detector 502 is provided as means for detecting an emergency condition, but other emergency condition detecting means may be provided. . In that case, a notification code is associated with each emergency state detection means and stored in the notification code storage unit 304, and the notification signal generation unit 301 selects the notification code corresponding to the detection signal, and the CATV management center. It may be configured to send to 2. Of course, it is also possible to send multiple notification codes. Further, if the fire detector 502 is a means that can detect the extent of a fire and outputs a detection signal according to the extent, a notification code corresponding to the extent of the fire is stored in the notification code storage unit 304. Then, the notification signal generator 301 selects the notification code corresponding to the detection signal, and C
It may be configured to send to the ATV management center 2.

On the other hand, in the emergency information management device 200 which constitutes the management device 2 provided in the CATV management center, the notification signal receiving unit 204 receives the notification of the area code and the notification code from each CATV converter, and the clock 203.
And stores the date and time information when the notification is received.

The date and time information can be added to the code to be notified when each CATV converter makes a notification. However, when each CATV converter has a built-in clock, an error occurs between the clocks. Yes, the date and time information cannot be added accurately, so the CATV management center side
One accurate clock is prepared, the date and time information when the notification is received is stored, and the emergency information to which the date and time information is added is transmitted to each CATV converter side later.

Next, the emergency information identifying section 205 refers to the emergency information management database 201 and identifies the content of the emergency video information to be sent to each CATV converter according to the received notification code.

In the emergency information management database 201, a notification code and emergency video information sent as emergency information are stored in advance in association with each other. For example, as the emergency video information, telop information such as “fire occurrence” can be considered.

Further, the area specifying unit 206 refers to the area management database 202, and specifies the area where the notification of the emergency video information to be sent to each CATV converter is generated according to the received area code.

The area management database 202 contains
The area code and the area name are stored in advance in association with each other. For example, it is telop information such as "Otemachi, Chiyoda-ku".

The distribution destination determining unit 207 refers to the area management database 202 using the area code, determines the distribution destination code, and passes it to the video signal generating unit 208.

The area management database 202 contains
The area code and the distribution destination code are stored in advance in association with each other. For example, when the area code means "Otemachi, Chiyoda-ku", the distribution destination codes are "Otemachi, Chiyoda-ku", "Kandanishiki-cho, Chiyoda-ku", and "Kuchida-Kanda, Chiyoda-ku".

It is also conceivable to store the notification code, the area code and the distribution destination code in association with each other. In the above example, when the report code means "fire outbreak", "Fire department that administers Otemachi, Chiyoda-ku" is added as the distribution destination code.

The video signal generation unit 208 adds the distribution destination code and the emergency video information to the date and time information, and adds each C
Send to ATV converter. The information to be sent to each CATV converter may be a telop of a program provided by the CATV management center by the mixer 100, or a predetermined C
It is preferable to use an ATV dedicated channel to send the information.

The emergency information dedicated tuner 303 provided in the CATV converter 3 receives the emergency video information with the distribution destination code sent from the CATV management center 2.

Then, if the area code stored in the area code storage section 305 exists in the distribution destination codes, the television display determining section 302 causes the video synthesizing circuit 306 to
It is decided to output the emergency video information, and the video composition circuit 3
The emergency video information is output to 06. In other cases, the emergency video information is not output to the video composition circuit 306.

At this time, when the power of the television 500 is off, the AC controller 307 forcibly turns on the power of the television.

The video synthesizing circuit 306 receives the video information or the video 50 received by the normal CATV tuner 308 for the viewer to tune in and watch the program.
1. Information obtained from an external device such as a game through an input terminal is superimposed on the emergency video information and output to the television 500 through the output terminal.

The switching mechanism is the video synthesizing circuit 30.
6 is a means for switching whether the signal input to 6 is either video information received by a normal CATV tuner 308 or information obtained from an external device such as a video 501 or a game through an input terminal, It may be configured to be switchable by a remote controller or the like. In addition, a video synthesizer circuit is built into the video 501 side,
The emergency video information received by the converter 3 may be input to a video synthesizing circuit incorporated in the video, the video information may be synthesized in the video, and the synthesis result may be output to the television 501.

As described above, since the distribution center area code is determined by the management center side, it is not necessary to provide a complicated area code comparison means on the CATV converter side.
It does not increase the cost of the ATV converter. In addition, emergency information with high regional characteristics is unnecessary information for subscribers outside the area, but by using the distribution destination code as in the present invention, unnecessary information is not displayed on the television. , It displays only necessary emergency information, so there is no flood of information.

For example, even if a fire occurs in a home away from home, emergency information can be promptly provided to a home television in a predetermined area by using CATV. Of course, CATV converters can be installed in public institutions such as the fire department to provide emergency information.

A fire may occur during absence,
If the report to the next house of the fire location is delayed, the fire may spread, which may lead to a delay in escape.However, as shown in this example, a fire detector that operates even while you are away , CATV converter to connect to CA
The TV management center can grasp the emergency information and
By using a regional code and sending emergency information to a CATV converter located in a predetermined area according to the code, even in the event of a fire from a household that is away, emergency information can be immediately sent to nearby households. Can be provided.

Further, since the date and time information is included in the emergency information by referring to the clock on the CATV management center side, there is an effect that the date and time information of the emergency information becomes accurate. By including the latest date and time information in the emergency information, it is possible to avoid confusion as to whether or not the telop indicates the current emergency information if a telop flows while the old recorded video is being played back as a video.

Also, while watching a normal program,
Although it is uncomfortable for the viewer to forcibly switch the channel for emergency information, a tuner for exclusive use of emergency information is built in, and a video synthesis circuit for synthesizing the emergency video information with the video information of a normal program is provided. By doing so, it is possible to know the occurrence of an emergency without switching programs.

Further, by providing an input terminal for video information from an external peripheral device and providing a video synthesizing circuit for synthesizing the video information given through the input terminal and the emergency video information, a television for video, karaoke, etc. Even when you are enjoying the entertainment you used, you can know if there is emergency information.

Next, with reference to FIGS. 4, 5, 13 and 14, an embodiment in which a region code indicating a CATV converter installation place is registered in the CATV converter according to the present invention.
And it demonstrates with reference to FIG.

It should be noted that only the constituent elements necessary for explaining the present embodiment are shown in the drawings.

Also, data is received from the bidirectional digital network system 1.

The operation of this embodiment will be described below.

First, when the reset switch 313 is pressed, the CATV tuner 308 selects a preset dedicated channel for initial setting. In addition, the notification signal generator 3
Reference numeral 01 denotes a transmission / reception terminal for extracting the initialization request code 311 (for example, the serial number of the converter is preferably adopted as the code) stored in advance in the initialization request code storage unit 311 unique to the CATV converter. The bidirectional digital network 1 is used to send the initial setting request code to the CATV management center 2.

In the emergency information management device 200 that constitutes the management device of the CATV management center 2, the notification signal reception unit 2

Number ”. When the answer is given in this way, the notification signal generation unit 301 again notifies the CATV management center 2 of the initial setting request code and the answer code “1” of “Chiyoda Ward”.

If the area code determining unit 211 of the emergency information management apparatus 200 of the CATV management center 2 can determine the area code to be registered according to the above-mentioned initial setting request code and reply code (that is, the first When a detailed place name list is displayed and an answer code is given), refer to the regional management database 202,
Select the area code for the answer code. Then, the video signal generation unit 208 attaches the area code to be registered to the initial setting request code, generates the video signal 1005 indicating the completion of the initial setting as shown in FIG. 15, and sends it to the converter.

In this example, the area code to be registered is
This is a regional code representing "1 Nishikanda, Chiyoda-ku". If the area code cannot be determined, more detailed initial setting menu images 1003 and 1004 as shown in FIG. 14 are generated according to the answer code.

In this example, since the answer is "Chiyoda Ward", a detailed image of Chiyoda Ward is generated.

When the television display determining section 302 finds its own initial setting request code and further finds the area code to be registered, the area code writing section 312 writes the area code in the area code storage section 305. to register. In this example, the area code is "1 Nishikanda, Chiyoda-ku".

With the above configuration, even if the installation location of the converter is changed, for example, due to a move, etc.

Similarly in FIG. 5, the processing explained in FIG. 3 is executed, in which the notification code and the area code are received, the distribution destination code is determined, and the emergency video information is sent to the CATV converter.

Next, an embodiment in which a CATV converter is provided with a facsimile and emergency information is transmitted will be described with reference to FIGS. 6, 7 and 3.

FIG. 6 shows a CAT arranged at the home side, for example.
The V-converter 3 and the CATV converter 3 are provided with a facsimile 504, and are connected to a facsimile communication network 505 for performing facsimile communication.

The CATV converter 3 has a notification code storage unit 304 for storing a notification code, an area code storage unit 305 for storing an area code which is a predetermined code indicating the arrangement area of its own converter, and a notification signal generation. It comprises a unit 301, an emergency number identification unit 321, an emergency number database 322, and a fax lock mechanism 323.

The CATV converter 3 is also connected to the bidirectional digital network 1 via an interface. Further, data is sent to and received from the bidirectional digital network 1 via the transmission / reception terminal.

On the other hand, FIG. 7 shows a configuration of the CATV converter 3 on the side of an organization (for example, a hospital, police, fire department, etc.) that receives emergency information, and performs processing for receiving emergency video information. It should be noted that only the configuration necessary for the description of the present embodiment is described. In practice, it is preferable to coexist with the configuration for performing the processing described in FIG.

As shown in FIG. 7, the CATV converter 3 on the engine side has a tuner 303 dedicated to emergency information and a video composition circuit 306. Moreover, it is connected to the television 500 through the output terminal. In addition, on the institution side, the facsimile 50 connected to the facsimile communication network 505
4 are arranged. The CATV converter 3 on the engine side is connected to the bidirectional digital network 1 via an interface. Further, data is sent to the bidirectional digital network system 1 via the transmission / reception terminal, and the bidirectional digital network system 1
Is receiving data from.

Now, the operation of this structure will be described.

First, it is assumed that the whistleblower at home sends a fax to the institution.

[0123] The reporter operates the fax transmission (for example,
When an operation of transmitting a handwritten message indicating the occurrence of an emergency) is performed, the emergency number identification unit 321 refers to the emergency number database 322 to identify whether the fax destination number is an emergency number. To do.

The emergency number database 322 contains
Fax numbers of institutions such as hospitals, police, and fire departments are registered as emergency numbers.

If the fax transmission destination number is an emergency number, the notification signal generating unit 301 causes the emergency number, the area code retrieved from the area code storage unit 305, the fax transmission source number, and the fax number. The signal is sent to the CATV management center 2 using the bidirectional digital network network 1 via the transmission / reception terminal.

The notification code storage unit 304 may store a notification code uniquely corresponding to the emergency number, add the code as header information, and transmit the emergency code instead of the emergency number. In this case, the management center may store the data in the database so that the fax destination number can be known from the notification code.

The structure of the management equipment provided in the CATV management center 2 is as shown in FIG.

At this time, the facsimile network 505 is also used to perform a normal fax signal transmission process.
As a result, the fax arranged at the institution receives the fax signal transmitted by the caller. It is also possible for a person on the engine side to see this and understand the occurrence of an emergency. Of course, when the fax destination number is not an emergency number, normal fax communication for transmitting fax signals is performed only by the facsimile network 505.

The fax lock mechanism 323 is a means for sending a fax signal to the CATV management center 2 only when a predetermined personal identification number is inputted from the facsimile, and it is effective in preventing mischief and erroneous operation. Have. Of course, not only the CATV management center 2 but also the fax lock mechanism 323 may be operated when sending a fax signal to an organization.

Now, in the emergency information management device 200 on the CATV management center 2 side, the notification signal receiving section 204 is
When there is a fax from the subscriber side,
By referring to the clock 203, date and time information is added to the notification.

When the urgent information specifying unit 205 determines that the sent information is a fax signal, it does not need to search the urgent information management database and sends the fax signal to the video signal generating unit 208.

The area specifying unit 206 refers to the area management database 202, extracts the area code and the emergency information, and sends them to the distribution destination determining unit 207.

The distribution destination determining unit 207 defines a distribution destination code for an organization transmitting a facsimile signal. In addition,
The area management database 202 stores in advance data in which an emergency number (report code in some cases) and a distribution destination code are associated with each other.

Then, the video signal generator 208 adds the fax signal, the fax transmission source number, the area, the date and time information as the video information, and further adds the distribution destination area code as the header information, and the video information is sent through the dedicated channel for the emergency information. send.

Upon receiving the emergency information from the management center 2, the emergency information dedicated tuner 303 included in the CATV converter on the institution side that receives the emergency information displays the video on the television 500.

The CATV converter arranged in such an engine does not have to include the television display determining section shown in FIG. That is, all the emergency information sent via the dedicated channel should be displayed. Of course, a region code storage unit that stores the region code may be provided, and the television display determination unit may determine that the distribution destination region code and the region code match and display only the necessary emergency information.

Even if the image information is not input from the facsimile, it may be determined that the input operation of the image information indicating the emergency is performed when the predetermined speed dial or the like is input. .

According to the above embodiments, for example, the whistleblower can
Even if you send a fax with the wrong fax number for the police and fire department, if the distribution area code for the police and fire department is the same, the contents of the fax will be displayed on the TVs installed at both institutions, so you should know it. The person in charge of the proper organization can know it without needing to resend the emergency information.
Also, since fax reception is not always monitored at all times, there is a high possibility that it may be delayed to notice that emergency information has been received only by fax communication.
If a television connected to the TV converter is used, the reception of emergency information can be grasped quickly and accurately. In addition, for the CATV converter that can be used with fax, in order to prevent mishandling and erroneous operation, it is necessary to release the fax lock mechanism only for homes with disabled people who can not talk so that only specific people can use it. it can.

Next, an embodiment in which the contents of the emergency information management database 201 provided in the CATV management center constituting the system according to the present invention are updated online will be described with reference to FIGS. 8 and 9. In addition, in the drawings,
