DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pay television broadcasting device used in hotels, inns, etc., for example.

Conventionally, in the above-mentioned pay television broadcasting equipment, a base unit uses a communal viewing device to supply pay television broadcasting signals together with general television broadcasting signals to the receivers in each room, and each receiver receives coins. Some devices were equipped with a device that enabled the reception of paid TV/con broadcast signals for a predetermined period of time when the system was turned on. However, in such a pay television broadcasting device, if the customer wants to watch the pay television broadcast even after a predetermined period of time has elapsed, the customer must insert a new coin, which is troublesome. Unfortunately, hotels and inns had to collect coins from each room at regular intervals, which was also a hassle.

The present invention solves the above-mentioned drawbacks and is a pay television system.
Each handset 2 is assigned a different address.

The base device 1 includes a transmission section 4, a status signal generation section 5, an address generation section 6, and a new regulation transmission section 7. The transmission unit 4 transmits broadcast signals including pay television broadcast signals to each machine 2 via the transmission line 3. Status signal generation unit 5
For example, it generates a transmission status signal indicating whether or not the transmission unit 4 is transmitting a pay TV/con broadcast signal. The address generation unit 6 updates the address signal every time it receives an update signal.

The new regulation transmitter 7 uses the transmission status signal and the address signal as a coarse side information signal 7 with a frequency different from that of the broadcast signal, and transmits the transmission path;
The data is sent to each slave unit 2 via the

Each slave device 2 includes an address setting section 8, a slave reception section 9, a slave address setting section 10, a situation determination section 11, a selection section],
? , , consists of a tuner section 13 and a slave transmitter section 14. Addresses assigned to each handset 2 are set in the address setting section 8. The secondary receiving section demodulates the address signal and transmission status signal from the coarse information signal.

The child address determination section 10 generates a first energizing signal when the address set in the address setting section 8 and the demodulated address signal match.

The situation determination unit 11 is energized by the first energizing signal,
A second energizing signal is generated when the demodulated transmission status signal indicates that the broadcast signal includes a pay television broadcast signal. The selection unit] 2 is activated by the second inquiry signal to generate a selection signal for selecting an advantageous television/con broadcast signal and a reception status signal. Tuner part] 3 is
A pay television broadcast signal is extracted from the broadcast signal in response to the selection signal. The slave transmitting unit 14 transmits the reception status signal and the address signal of the address setting unit 8 to the base unit 1 via the transmission line 3 as a slave information signal having a frequency different from that of the broadcast signal and the coarse information signal. .

The base unit 1 includes an observation receiving section 15, an observation address determining section 16, and a processing section 17 in addition to those described above. The observation receiving unit 15 demodulates the address signal and reception status signal from the child side information signal. The observation address determination unit 16 generates a third observation signal when the demodulated address signal and the address signal of the address generation unit 6 match. The processing unit 17
It calculates charges based on the demodulated reception status signal that has been updated by the energizing signal, and also supplies an update signal to the address generation section.

Therefore, according to this pay TV/con broadcasting device, the base unit 1 can call each slave unit in turn, grasp the usage status of pay television broadcasts, and perform charge management. Therefore, the guests in each room can continue to watch paid TV/broadcasts without having to insert coins every predetermined period of time. Inns and hotels can also pay when guests check out, saving them the trouble of collecting coins from each room.

Hereinafter, the invention will be explained in detail based on one embodiment shown in FIGS. 2 to 5. FIG. 2 is a block diagram of one parent machine. In the figure, reference numeral 2o denotes a hand end, which supplies three types of barbed television signals and one type of emergency broadcast signal supplied from the automatic driving device 22 to each slave device via a joint viewing device. Of the three types of pay television signals, the first one P is alternately supplied from the VTRs 26a, 26b, and similarly the second one P2 is supplied from the VTRs 28a, 28.
b alternately, and the third one P3 is supplied from VTR 30a.
, 30b alternately. The emergency broadcast signal is supplied from the VTR 32 and the video terror transmitter 34. The automatic driving device 22 is a central processing unit (CPU')
36, the operating status of each VTR is input.

In the CPU 36, the charges per unit time for three types of barbed ten vision broadcasting are separately set from the charge setting Tagitarus 1 Sochi 38. A clock signal is still being supplied from the timer 40. In fact, the address for each slave device is also set using the address program switch 42 and numeric keypad 44). This address setting is C
The room number in which each handset is installed corresponds to the absolute address, for example, 1 to 254"4, which is built into the PU36. Therefore, the calling order of each handset can be changed arbitrarily. -Also, for example, if you associate absolute address 5 with a room number of 1, then skip two absolute addresses and associate the next room number with absolute address 8, addresses after absolute address 8 will be ignored. .C.
In addition to this, commands to be transmitted to each slave unit are set in the PU 36 using a function key 46.

The CP"JX5c+ generates a data signal based on the absolute address signal, the information signal from the automatic driving device M22, and the command from the Whor/Re/Conkey 46. This data signal 1c"1, start code, absolute address. It consists of a coat and a control coat. Control two coats ■). It consists of 8 hits of 7, and there are 3 types of Do? '＋
It represents the presence or absence of the entire television broadcast signal, Dl represents whether the first one P of the pay TV/con broadcast signal is being transmitted, and D2 represents whether the second one P is being transmitted. ■) 3 indicates whether the third signal P3 is being transmitted, D4 indicates whether the emergency broadcast signal is being transmitted, and D5 indicates whether the emergency broadcast signal has stopped J-. D6 represents whether to stop the power of the receiver of the slave unit, and D7 represents whether to request information on the refrigerator connected to the slave unit. This data signal is repeated six times and supplied to the serial/parallel converter 48, where it is converted into a serial signal and supplied to the transmitter 50. The transmitter 50 is a 13 MHz FS modulated by a serial signal.
The K signal is supplied to the communal viewing and viewing device via a filter 52 and a mixer 54, and is then transmitted to each child device.

From each handset (is modulated with a data signal consisting of its own absolute address code and control code!-5MHz F)
An SK signal is sent back. This FSK signal (is supplied to a receiver 56 via a mixer 54 and a filter 52,
After being demodulated here, the CP
Supplied to U36. The CPU 36 determines whether the demodulated address code matches the address code called by itself, and if they match, calculates the charge, displays the room number of the called handset on the room display LED 5B, and outputs the TV mode. Displays which of the pay television broadcasts the called handset is watching on the section 60, and displays the charge display LE.
The charge is displayed on D62. Then, call the next slave device in the same way.

Finally, the CPU 36 prints out the fee for the pay television broadcast via the printer 64 when the guest checks out.

The above operation will be explained according to flowchart 1 shown in FIG. Hey, let's assume we've already done the correspondence between the absolute address and the room number. In step 66, rate data is entered. Step 70 receives a data signal from the slave device. Stesogame]2, determine whether 171 seconds have passed since the data was sent. If the elapsed time has not elapsed, it is determined in step 74 whether the CPLI 36 or the data signal can be captured. If the data signal cannot be captured, the process returns to step 72, and if it is possible to capture the data signal, the process returns to step 7.
Step 6 takes in the data signal. Then, in step 78, it is determined whether or not the address code on the back of the data signal matches the address code called by the base unit. It is determined whether or not the first Pl is being viewed, and if it is being viewed, it is stored in the memory in step 82.If the P is not being viewed, or following step 82, the second paid one is being viewed in step 84. Television broadcast P2
It is determined whether or not the user is viewing, and if so, it is stored in the memory in step 86. If P2 is not being watched, then following step 86, it is determined in step 88 whether or not the third pay television broadcast P3 is being watched, and if so, it is stored in the memory in step 9o. If you have not seen P3, or following step 9o, in step 92,
It is determined whether or not an emergency broadcast is being made, and it is stored in the memory in step 94.

If you are not watching the emergency broadcast or following Stesoge 94, it is determined in step 96 whether or not the handset's television receiver is energized, and if it is, step 94 is selected.
8 memorize it in memory.

If the receiver is not energized, following step 98, it is determined in step 100 whether or not there is a numeric keypad, and if there is an input, the LED is displayed in step 102, and Funk/Yon is selected in step 104. input. Then, in step 106, it is determined whether pay television broadcasting is being received, and if so, in step 108, the charge is calculated and displayed based on the value stored in the memory. If you are not watching pay television broadcasting, continue to step 10B and determine whether general television broadcasting is being received in step 11.0, and if it is, display the lamp in step 1 and step 2. . If general television broadcasting has not been received yet, proceed to Step 1]4 following Step 2, and input external news from the automatic driving device 22. If there is no numeric keypad input in step 100 (
Go directly to step 114. Following step 114, the process returns to step 66 and repeats the steps described above.

However, the address code of the data signal to be sent in step 68 has been changed to the new 7z one, and the control code is also changed when new data is added in step 104. If there is a change in the external input input manually, the result will be different from the previous one.

By the way, if data cannot be received from the handset even after i0 m seconds have passed after data transmission in step 72, if the addresses do not match in step 78, step 1
16, the re-speed counter C1 which is initially reset
Step forward by one. That is, the count value of C1 is set to 1 and it is determined in step 118 whether the value of CI is 2 or not. If it is not 2, the process moves to step 68;
Call the slave device with the same address again. If there is still no data sent from the handset or the addresses do not match, 01 becomes 2 again in step 116, and step 1
The process moves from 18 to 120, where the address error counter C2, which was initially reset, is incremented by one. That is, the count value of C2 is set to 1. And step 1
At step 22, it is determined whether or not 02 is 2, and if it is not 2, the process moves to step 68, where 1r-+M, which is considered to be the fault, is removed and the next slave unit is called. Call all slave units and execute steps 78 to 120 again for the slave unit that seems to be in trouble.
If there is no response after repeated calls, step 120
Then, the value of the address error counter C2 becomes 2, and the process moves from step 122 to step 124, where the fault lamp is turned on, and then the process moves to busy step 100.

By the way, a circuit as shown in FIG. 4 is inserted between the automatic driving device 22 and the CPU 36. This is because the automatic operation device 22 generates an on signal when the VTR is in operation and an off signal when it is not in operation, but when switching between VTRs 26a and 26b and when switching between VTRs 28a and 28b,
When switching between the VT'Rs 30a and 30b, the automatic operation device 22 or J (generates a level signal (2) will transmit the stiffness to the CPU 36 or slave unit, so this is meant to prevent this.

When the VTR is operating, the input of the inverter 126 is at the L level and the output is at the H level. Its F (level output is connected to a capacitor via a diode 128 and a resistor 130) 3
2 is charged, and the lightning becomes H level.

This) ■ level output is from the resistor 134, ]36 and the inverter 138, ]. 40 is supplied to the circuit 142, and its output becomes H level.

The CPU 56 determines that the VTR is in operation. V
When TR is inactive, the input of inverter 126 &-1H
level, and its output id becomes L level. As a result, the capacitor 132 is discharged via the resistor 144, so that after the time t (approximately 10 seconds) determined by the values of the capacitor 132 and the resistor 144 has passed, the voltage becomes less than the threshold of the Schmitt circuit 142, and the Schmitt circuit 142 is discharged. The output becomes L level. However, in the case of VTR switching,
Before time t elapses, the input of the inverter 126 becomes L level again, so the output of the /YUMINOTO circuit 142 maintains the H level, and the CPU 36 determines that the VTR is operating. Note that 143 is a bias resistor.

Now, the signal from the head end 2o and the FSK signal from the transmitter 5° (are transmitted to each handset via the joint viewing and viewing device, and the amplifier 146 used in this joint viewing and viewing device is shown in FIG. A mixer 1 is connected to the input side and the output side of the amplifier 148 capable of amplifying the signal from the head end.
．． 50.152 is installed, and the transmitter is set at 5 degrees.

The signal from the head end 20 and the FSK signal from the transmitter 50 transmitted to the handset in this way are filtered by the filter 15.
4, the FSX signal is demodulated into an arc signal by the receiver 1, 56, and is supplied to the CPU 158. - As mentioned above, since the arc signal is repeatedly transmitted three times, the CPIJ 158 assumes that it is correct if two of the three are equal, and that the address code of the arc signal is the address set in the address setting section 16O. If they match, determine whether D4 to D3 of the control code match, and whether D to D3 indicate that some of the barbed television broadcast signals P1 to P3 are being transmitted. , the display output unit 1G2 displays the receivable channels from P1 to P3, and the channel selection circuit 164 is brought into a state where it can select the channel from P to P3 that is received nJ1. In this state, operate the channel selection switch 166 to select from Pl to P.
When one of the three channels is selected, the tuner 168 extracts the selected channel from the filter-separated signal from the head end 2Q and supplies it to the converter 170. Converter 170 converts this into a signal of a specific frequency and supplies it to a television receiver. Such an operation is controlled by control code D. Of course, this is not carried out when the symbol indicates that pay television broadcasting is not being carried out.

Then, the CPU 158 determines the control code D4, and if D4 indicates that an emergency broadcast is being performed, controls the channel selection circuit 164 so that the tuner 168 extracts the emergency broadcast signal. The power output unit 172 is configured to forcibly energize the television receiver in consideration of the possibility that the power switch of the television receiver is still open.
control. Furthermore, if the sterilization code D5 is determined and the emergency broadcast is stopped, the channel selection circuit 164 is controlled to stop the tuner 168 from extracting the emergency broadcast signal. . In addition, the power output section 172 is configured to stop forcibly energizing the television receiver.
control. Note that even if the forced energization is stopped, if the power switch in the receiver is closed, the receiver will continue to be energized. D6 of the control code is determined, and if the receiver has been energized for a long period of time, the power output section 172 is caused to stop energizing.

Further, the CPU 158 determines D7 of the control coat,
If indicates that information from the refrigerator is requested, the refrigerator information is fetched via the expansion unit 174.

Following this, the i CPo 158 sets the address setting unit 1
60 address code and the tuning status of the tuner (
Which of the 1st to 3rd pay TV broadcasting signals are being received, and whether or not the emergency broadcasting signal is being received)
A booter signal is formed as a set including a control code indicating whether the signal is energized or not, and this is repeated 3 times and supplied to the transmitter 1'76.
Refrigerator Clearance '45 If requested, create an arc signal using the address coat, control coat and O/refrigerator information coat as a set, repeat this three times, and send the transmitter.
76. The transmitter 176 generates a 5.5 MH2 FSK signal modulated by the arc signal, and transmits it to the base unit via the filter 154 and the communal viewing and viewing device. This FSK signal is processed in the base unit as described above.

Note that 176 is a funk/yonkey for CPU] and 58.

In the above embodiment, there are three types of pay television broadcast signals, Pl to P3, but the number can be increased or decreased as desired.
