Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a television receiver with a built-in individual selective call receiver suitable for a forced reception system for emergency broadcasts.

(Prior Art) As is well known, television receivers, like radio receivers, are widespread in every household, so it is conceivable to make emergency broadcasts using television radio waves.

That is, the contents of the emergency broadcast are displayed in text on the picture tube of the television receiver, or audio is broadcast from a speaker along with the text display.

Here, emergency broadcasts include, for example, advance notices or warnings of earthquakes and tsunamis, accompanying notifications of evacuation routes, notifications of outbreaks, notifications of fire outbreaks, as well as notifications of riots and air noise warnings, etc. Contains things.

(Problems to be Solved by the Invention) By the way, when making emergency broadcasts using television radio waves, it is necessary to consider the following various matters.

First of all, it is necessary to be able to specify the area and broadcast.
For example, there may be a need to broadcast to specific individuals, such as firefighters.

In addition, since this is an emergency broadcast, it is necessary to be able to forcibly turn on the power of the television receiver if it is not turned on, and it is also necessary to be able to notify that the emergency broadcast will begin before the broadcast starts. It is. Since there are a plurality of reception channels for television broadcasting, it is desirable to be able to notify which reception channel should be selected, and preferably to be able to automatically switch reception channels.

The above discussion is based on the nature of emergency broadcasts, but it is also necessary that a television receiver equipped with the function of receiving emergency broadcasts be easily installed in ordinary households.

Television receivers equipped with this function will be more expensive due to the added functionality, but since emergency broadcasts occur very infrequently, it will be difficult to popularize them in general households simply by providing this function. In that case, it would be impossible to construct an emergency broadcast system using television radio waves.

The present invention was made in view of the importance of emergency broadcasting, and its purpose is to focus on the functions of individual selective paging receivers that are widely used in the field of mobile communications, and to develop a system suitable for the forced reception system of emergency broadcasts. An object of the present invention is to provide a television receiver with a built-in individual selective call receiver.

(Means for Solving the Problems) In order to achieve the above object, a television receiver with a built-in individual selective call receiver according to the present invention has the following configuration.

That is, the television receiver with a built-in individual selective call receiver of the present invention is capable of receiving a call transmitted by a broadcasting station separately from the television broadcast radio waves. a receiving means for receiving radio waves;
A control means for issuing the power-on command as well as an alarm command when the calling signal received by the receiving means is addressed to the receiving means; and a sounding means for generating an alarm sound in response to the alarm command. It is characterized in that an individual selective call receiver is built in so that it can be separated.

(Function) Next, the function of the television receiver with a built-in individual selective call receiver of the present invention constructed as described above will be explained.

The individual selective paging receiver receives the paging radio waves transmitted by the broadcasting station separately from the television broadcast radio waves (operation of the receiving means), issues the power-on command when the received paging signal is addressed to the receiver, and issues an alarm. Issue a command (operation of the control means), as a result, the individual selective call receiver generates an alarm sound (operation of the sound generation means), and notify users of the television receiver that there is an emergency broadcast; At the same time, the power of the television receiver is turned on if it is in the off state. After transmitting the paging radio wave, the broadcasting station transmits the emergency broadcast content on the TV radio wave, so the user can learn the content of the emergency broadcast by tuning the channel on the television receiver.0Individual selective call Since the receiver is built-in and can be separated, it can be placed close to the user, for example by placing it next to the pillow while sleeping, ensuring that the user is not near the television receiver. It is possible to communicate that there is an emergency broadcast. Therefore, the power supply for the individual selective calling machine is of an uninterruptible type.

Furthermore, it is expected that the power of the television receiver will not be turned on due to the fact that the AC outlet is unplugged, but even in this case, the user can use the warning sound to notify the user that there is an emergency broadcast. It becomes possible to take appropriate measures.

The above is the basic operation, but the following functions can be added. First, since the calling signal can contain general information such as the date and time of occurrence and the name of the place, if the general information contained in the calling signal is sent to the video signal amplification stage of the television receiver (control means (operation), users can know the general content of emergency broadcasts without having to tune in to any particular channel.

Additionally, as is well known, some individual selective calling receivers have a display that can display a simple message.
When such an individual selective call receiver with a display is used, the general information can be displayed on the display (operation of the control means).

Furthermore, in order to eliminate the complexity of channel matching,
A television receiver allows a local oscillator to change its local oscillation frequency according to an external change command. In this way, the control means can issue the change command based on the receiving channel designation signal included in the calling signal, making it possible to automatically switch the receiving channel.

Finally, in order to enable the television receiver to be easily accepted into general households, the television receiver is further capable of turning off the power in response to a power-off command, and also has the ability to turn off the local oscillator and audio. To enable a signal amplifier to change the local oscillation frequency and volume according to an external change command. A remote controller capable of transmitting a paging radio wave separately from the broadcasting station is attached to the individual selective paging receiver, and the control means controls the power source according to instructions of a paging signal based on the paging radio wave transmitted by the remote controller. A power-on command, a power-off command, and a change command are issued respectively. In other words, the television receiver can be used as a so-called remote control television, and even if the additional functions increase the price, the television receiver can still be enjoyed with the added functions, making it possible to popularize it in general households. It becomes possible.

As described above, according to the television receiver with a built-in individual selective call receiver of the present invention, the original functions of the individual selective call receiver can be effectively utilized, so that the advance notification function in case of an emergency,
Not only the automatic forced power-on function can be realized, but also various other functions in the forced reception system for emergency broadcasts can be easily realized.

Furthermore, by attaching a remote control device to the individual selective call receiver, there are effects such as making it easier to receive the receiver in general households.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a television receiver with a built-in individual selective call receiver according to an embodiment of the present invention.
The television radio waves received by the antenna 1 are input to the high frequency amplifier 3 via the feed line 2, and the output of the high frequency amplifier 3 and the output of the local oscillator 10 are received to form a video intermediate frequency signal of a predetermined channel. A mixer 4, a video intermediate frequency amplifier 5 receiving the output of the mixer 4, a video detector 6 receiving the output of the video intermediate frequency amplifier 5, and a synchronizing signal generator 8 receiving the output of the video detector 6 and audio. a video signal amplifier 7 that sends a predetermined signal to the intermediate frequency amplifier 11; a picture tube 9 that receives the output of the video signal amplifier 7 and the output of the synchronization signal generator 8 to draw a television image; and an audio intermediate frequency amplifier 11.
The audio detector 12 basically includes an audio detector 12 that receives the output of the audio detector 12, an audio signal amplifier 13 that receives the output of the audio detector 12, a speaker 14, and a power supply section 28. This television receiver 1lfi has the same configuration as the conventional one and is well known, so it will not be reconstructed, but in order to incorporate an individual selective call receiver, the present invention is configured as follows.

First, the power supply section 28 uses an AC power source 29 which is an external power source.
Alternatively, the DCtC power supply 30 receives the power supply and supplies operating power to each part, but in the present invention, not only can the supply of operating power be turned on and off by manual operation, but it can also be turned on and off by external commands like a so-called remote control TV. It is now possible to do so. That is, as shown in FIG. 1, this power supply section 28 is also connected to the individual selective call receiver, and receives a power-on command and a power-off command as described later.

In addition, the antenna 1 can be shared by an individual selective call receiver, and is further equipped with a video signal amplifier 7 and a local oscillator 1.
0 and the audio signal amplifier 13 can be controlled by the individual selective call receiver.

The individual selective call receiver includes an antenna 15, a mixer 16,
Demodulator 17, processing section 18, information processing control section 19,
A display 20, a local oscillator 21, a number storage unit 22,
An oscillator 23, a speaker 24-, a control drive section 25,
It includes a battery 26 and a charger 27.

The battery 26 supplies operating power to each part, and in this embodiment, it can be charged by a charger 27 connected to a power supply part 28.

Of course, it doesn't have to be a rechargeable type.

Since this individual selective call receiver is separably built into the television receiver, the two are connected via a cable of a predetermined length. Therefore, either the antenna 1 or the antenna 15 can be used to receive the calling radio waves either when the antenna is built in or when it is removed and carried.

Note that the antenna 15 is originally provided in the individual selective call receiver.

The paging radio waves are emitted from a broadcasting station that performs emergency broadcasts or from a remote controller (described later) operated by the user of the television receiver. This calling radio wave consists of a frequency different from that of the television radio wave, and this is the antenna 1 or the same 1
5 and input to the mixer 16.

The mixer 16 performs a predetermined frequency conversion on this input signal based on the local oscillation frequency signal from the local oscillator 21.
It is sent to the demodulator 17.

As a result, the calling signal is restored in the demodulator 17, and 0 or more signals inputted to the processing section 18 are the operations of the receiving means.

Here, the calling signal basically consists of a "synchronization section J," a "number section," and a "command section," and when the display 20 is provided, an "information section" is further added.

When a broadcasting station transmits, the ``number part'' includes a region-designated number and a personal-designated number, the ``command part'' includes a power-on command and reception channel designation, and the ``information part'' includes summary information. In addition, when a remote controller transmits data, the "number part" is the same as above or consists of a personally designated number, and the "command part" consists of a power-on command, reception channel designation, volume increase/decrease command, and power-off command. . Use of “Information Department” is optional.

Processing unit 182 number storage unit 22. The information processing control section 19 and the control drive section 25 constitute a control means as a whole. The processing unit 18 and the number storage unit 22 determine whether the calling signal restored by the demodulator 17 is addressed to the user, and if the calling signal is addressed to the user, the calling signal is transmitted to the next stage information processing control unit. 19. That is, the number storage unit 22 stores in advance various identification numbers such as the identification number of the region to which the television receiver belongs and the identification number of the user of the television receiver at a personal level. The processing unit 18 determines whether the content of the "number part" of the calling signal matches the content read from the number storage unit 22.

The information processing control section 19 performs the following processing operations based on the contents of the "command section" and "information section" of the call signal.
When the content of the “command section” is a power-on command, the oscillator 2
3 and the control drive unit 25. In addition,
When the power-on command is related to transmission from a remote controller, there is no need for a start-up command to the oscillator 23. the result,
The oscillator 23 causes the speaker 24 to generate an alarm sound to notify the user that an emergency broadcast will begin.

Further, the control drive unit 25 sends a control signal to the power supply unit 28 to indicate that the power should be turned on. In response to this, the power supply section 28 turns on the operating power of each section if it is not already turned on. At this time, if the AC power supply 29 is disconnected and the power cannot be turned on because there is no external power supply, the power supply section 28 outputs a signal indicating failure to turn on the control drive section 25 . In response to this, the control drive unit 25 starts the oscillator 23
is controlled to generate an alarm sound different from the above-mentioned alarm sound from the speaker 24 to notify the user that the television receiver is not powered on.

The user can take appropriate measures such as connecting an external power source or investigating and repairing abnormalities.

In addition, when the content of the "command section" is a reception channel designation, a volume increase/decrease command, a power off command, etc., the signal is sent as is or converted into a corresponding control signal and sent to the control drive section 25.
Send to. As a result, the control drive section 25 operates as a local oscillator 1.
0, a volume control signal to the audio signal amplifier 13, and a signal to the power supply unit 28 to turn off the power. In other words, the receiving channel can be automatically switched from the broadcast station and the remote control, and the volume can be increased/decreased and the power turned off from the remote control.

Note that when there are multiple contents of the "command section", the operations indicated by those contents are performed in parallel. Further, a "command unit" related to broadcast station transmission can include a volume increase/decrease command.

Next, the information processing control section 19 controls the display of the general information included in the "information section". If the individual selective calling receiver does not have the display 20, the information processing control section 19 transmits the general information to the video signal amplifier 7. If a display device 20 is provided, the signal is sent to the display device 20.

In the latter case, it may also be sent to the video signal amplifier 7, so that the general information is displayed on the picture tube 9 and/or the display 20. Here, the general information consists of short sentences or short words such as the date and time of the occurrence of the emergency situation and the name of the place. The detailed content will be broadcast by the broadcasting station via television radio waves.

Next, FIG. 2 shows a remote controller according to an embodiment of the present invention. This remote controller includes an operating section 31, a power supply circuit 32, a signal generator 33, an FM modulator 34, and a power amplifier 3.
5 and an antenna 36.

The operation section 31 includes an operation switch for turning on the power supply circuit 32, a setting switch for setting the contents of the "number section" and "command section" of the calling signal, and the like.

The power supply circuit 32 is turned on for a certain period in response to the operation of the operation switch, and supplies power to the signal generator 33, FM modulator 34, and power amplifier 35 during that period. This power supply circuit 32 prevents wasteful power consumption of the power supply battery.
After a certain period of time, power supply to each part is stopped.

The signal generating unit 33 responds to the operation of the setting switch on the operating unit 31 and generates a "synchronization part", a "number part", and a "number part" of the calling signal.
It forms each signal of the "command section" and sends it to the FM modulator 34.

The FM modulator 34 has an oscillation circuit composed of a crystal oscillator or the like to generate a frequency assigned to the individual selective calling receiver, and the calling signal is converted into FM and sent to the power amplifier 35.
sent to.

As a result, the ringing signal is transmitted to the antenna 3 via the power amplifier 35.
6 as a paging radio wave, which is received by the antenna 15 of the individual selective paging receiver.

In this way, the television receiver can be enjoyed as a so-called remote control television by using this remote controller, and the receiver can be easily installed in ordinary households.

(Effects of the Invention) As described in detail above, according to the television receiver with a built-in individual selective call receiver of the present invention, the original functions of the individual selective call receiver can be effectively used, so that Not only the advance notification function and the automatic forced power-on function can be realized, but also various other functions in the forced reception system for emergency broadcasts can be easily realized.

Furthermore, by attaching a remote control device to the individual selective call receiver, there are effects such as making it easier to receive the receiver in general households.
