At the same time, the power supply driving circuit 44 energized by the third energizing signal 40 starts energizing the television receiver. As a result, even if the viewer has stopped the power supply to the television receiver, the television receiver is forcibly brought into the receiving state. Furthermore, the forcing section 46 is energized by the third energizing signal 40, and the forcing circuit 46 causes the selecting section 30 to generate a selection signal for causing the tuner section 34 to extract the emergency broadcast.

This allows you to view the contents of the emergency broadcast on your television receiver.

Hereinafter, this invention will be explained in detail based on one embodiment shown in FIGS. 3 and 4. In FIG. 3, 50 is a terminal that receives television broadcast signals and information signals from the base unit via the communal viewing device. This television broadcast signal includes three types of pay television broadcast signals in addition to multiple general television broadcast signals, and in the event of a disaster, multiple general television broadcast signals or three types of pay television broadcast signals are included. An emergency broadcast is made by one of these systems to notify of the occurrence of a disaster, etc.

Information signals include start code ST, address code PAD
, control code C, STX AD.

C, AD, , C, AD, C are arranged in the order of one word. Address code ADil? It consists of bits and represents the address of the child device that the parent device is trying to call. In addition, it is made up of control Fc mo8 hits, and if the Do is "0" and the old is "self", it means that the first paid Ten Vision broadcasting signal is being transmitted, and the DO is "o". ", if Dl is "1", it means that the second pay television broadcasting signal is being transmitted, and if Do is "o" and D3 is "1", the third pay television broadcasting signal is being transmitted. Indicates that transmission is in progress. Also,
When Do is “1” and Dl is rtJ, DO is I”’+J
When Dl is rtJ, D.

When D3 is "1" and D3 is "1", it means that the first, second, and third pay television broadcast signals are not being transmitted. When D4 is "1", it indicates that an emergency broadcast is being made. When D5 is rtJ, it indicates that no emergency broadcast is being made. When D6 is "1", it indicates that the power of the television receiver is turned off.

Dl is always set to "1", which has no meaning.

The information signal and the television broadcast signal supplied to the terminal 50 are separated by a filter 52, and the information signal is sent to the receiving section 54.
The signal is demodulated and supplied to the CPU 56 (see step 58 in FIG. 4). Further, the television broadcast signal is supplied to the tuner 60.

As shown in step 62, the CPU 56 determines whether the address code AD matches its own address already set by the address set switch 64 (see step 66), and if so, proceeds to step 68. In addition, the fourth
In the flowchart shown in the figure, step 62 is shown to be performed only once, but in reality, step 62 is repeated three times, and if the results match all three times, the process moves to step 6.

In step 6, it is determined whether or not DO of control code C is "I", and if it is "O", the process moves to step 7o.

Step 70 determines whether Dl is "1" and determines whether Dl is "1".
”, a first pay television release signal is generated in step F12. This release signal is supplied to the pay TV on-air output circuit 74. The output circuit 74 lights up the light emitting diode 76 to indicate that the first pay television broadcast signal is being transmitted, and also energizes the first pay television broadcast selection switch of the selection switch 78. Following step 2 or when Dl is rOJ in step 7o, proceed to step 8o, and Dl is "1" or "0".
However, I judged it to be "0" and moved it to the alto step 82,
A second pay television release signal is generated. As a result, the output circuit 72 is connected to the light emitting diode 84 during pay TV broadcasting.
, and energizes the second pay television selection switch of selection switch '7B. Following step 82 or in step 80 if Dl is l'-OJ, step 8
Move on to 6. Step 86 judges whether D3 is "1" or not, and if it is "1", a third pay television release signal is generated in step 8. As a result, the pay television broadcasting output circuit 74 turns on the light emitting diode 9o and energizes the third pay television selection switch among the selection switches 78. Note that DO is "1" in step 68.
If so, the process moves to steps 92 to 102, the light emitting diode '76.84.90 does not light up, and the selection switch 78 is not activated.

When the selection switch 78 is energized and the viewer operates the selection switch 78, the tuning device 104 sends a selection signal to the tuner 106. With this, tuner 1
06 extracts a specific barbed television broadcast signal from the television broadcast signal separated by the filter 52,
Supplied to converter lO8.

Converter 108 converts this into a signal of a specific frequency and supplies it to a television receiver. On the other hand, the channel selection device 10
4 supplies a signal indicating that a pay television broadcast signal is selected to the pay television channel selection input circuit +10. This circuit 110 transmits the signal to CPU 56. The CPU] 56 inputs the above signal in step +12, sends out a control output to the transmission section 6 in step 114, and supplies transmission data to the transmission section +16 in step 118. The transmitter 116 modulates this and transmits it to the base unit via the filter 52, the terminal 50, and the communal viewing device. Note that, for a certain period of time after the selection switch 78 is operated, the channel selection device 104 inputs the pay television channel selection input circuit +
No signal is provided to 10. This is because the service is free until you decide which pay television broadcast to watch.

A contact 128a of the relay 12B is connected to a power supply unit +31 in series with a television receiver outlet 129, and when the contact 128a is closed, the television receiver is energized. At the same time, the CPU 56 sends a signal to the emergency broadcast instruction output circuit 130 to 1. This circuit 130 generates a selection signal for selecting the emergency broadcast in the channel selection device IO4. This allows tuner +
06 extracts the television broadcast signal that is broadcasting the emergency and supplies it to Konno-Yu 10B.Therefore, even if the guest is sleeping, the alarm will wake them up and the television will automatically turn on. The receiver is turned on and the emergency broadcast can be viewed.The alarm sound can be stopped by activating the alarm stop circuit 132.

Following step 1204 and step 12.2, step 134
It is determined whether D5 is "1" or not, and if it is "l", the alarm circuit 124 and relay drive circuit 125 are stopped, and the signal supply to the emergency broadcast instruction output circuit 130 is stopped.

Following step 124 or 125, step: 77”13
Step 4, determine whether D6 is "1" and set it to "1".
If so, the process moves to step 136 and the television power source is cut off. This is to save electricity when the television receiver is out of service for a long time, or when the television receiver is left on at night when sleeping, regardless of the presence or absence of emergency broadcasts. It will be done.

In addition to this, this receiving device also uses paid TV/TV on the base unit.
When transmitting a signal indicating that a broadcast is selected, a signal indicating the usage status of the refrigerator is also transmitted. For this purpose, refrigerator information extension I10138 is provided. Further, a signal indicating whether an emergency broadcast is being received or not and a signal indicating whether the television receiver is energized are both transmitted together with the refrigerator usage status signal.

In addition, a sleeve input circuit 138 is also provided, and when this is operated, the CPU 56
stops powering the television receiver.

As described above, according to the pay television receiving device according to the present invention, not only can pay television broadcasts be received, but also emergency broadcasts can be reliably notified.

In the above example, the number of pay television broadcast signals is 3.
However, the number can be increased arbitrarily.
