The PHS built-in unit 4 connects the billing information from the tuner 1 to a BS (base station of a PHS system) 5 and is connected via a wired line 7 to a billing facility 8 of a broadcaster facility.

The broadcast wave is transmitted from the satellite broadcast equipment 9 to the antenna 3 of the home equipment by relaying the broadcast satellite 10. The broadcast wave received by the antenna 3 on the home facility side is broadcasted on the television 2 via the tuner 1.

Next, each block of the tuner 1 will be described with reference to FIG. The high-frequency signal input from the antenna 3 to the tuner 1 is received by the receiving unit 21, a predetermined channel is selected, and the signal is demodulated to baseband by an intermediate frequency amplifier circuit or a demodulation circuit. Baseband signal is descrambling circuit 2
The scrambled video signal, audio signal, and data signal are descrambled, and the modulator 28 modulates the signal into a signal receivable by the television 2 and sends the signal to the television 2. in this case,
If the TV 2 has a video signal input terminal,
The modulation section 28 does not necessarily have to be provided.

When a video signal, an audio signal, and a data signal scrambled by the antenna 3 are received, the data processing unit 26 sets the channel for which reception has been reserved in advance to the channel selection frequency of the reception unit 21 and the TPV. In the case of (1), the time is counted by the counter 24 from the channel selection setting, and the viewing time is sequentially stored in the memory 25. Data processing unit 2
Reference numeral 3 denotes a preset descrambling key, which turns on the descrambling of the descrambling circuit 22 and cancels the scramble signal. In the case of IPPV, the data processing unit 23 similarly sets the receiving unit 21 to the channel for IPPV, turns on the descrambling of the descrambling circuit 22 with the preset descrambling key, and cancels the scramble signal.

Further, the data processing unit 23 connects the connector 27 to which the connection cable 11 is connected via the modem 26 to the PH.

The PHS terminal 34 includes an RF unit for transmitting and receiving to and from the base station 5, a baseband signal processing unit for transmitting and receiving to and from the RF unit, an analog unit such as a microphone and a speaker, and a battery unit such as a lithium battery capable of transmitting and receiving for a long time. And a keyboard unit. Note that FIG.
The operation of each unit described in (1) will be described later.

FIG. 3 is a diagram for explaining an example of transmission of a scramble signal used in the present embodiment. In the case of the video signal of the NTSC system, scramble data is inserted by the PSK system after the equalization pulse of 21H in the vertical blanking period. This PSK
The signal may be descrambled by the descrambling circuit 22 when the signal is compared with the descrambling release key received in advance via the modem 26 in the data processing unit 23 and the signals match. The insertion part and the insertion method of the scrambled data are not limited to those described above. In the case of the MUSE system high-vision signal, it can be inserted into the control signal part. Can be broadcast. There are various scramble methods, for example, a method of dividing a horizontal line of digital video data into a plurality of blocks, and any of the methods can be used in the present invention.

The descrambling system is as follows. When a broadcaster guides an IPPV program on a television screen and matches a program to be viewed from an operation unit (not shown) with a selected polygon, the data processing unit 23 transmits the IPP program to the program.
The V program name and its viewer ID are transmitted as a set to the modem 26, and the modem 26 connected to the PHS terminal 34 performs an operation according to a program from a broadcaster in advance, specifies a telephone number, and The PHS base station 5, the public telephone wired line 7, and the billing facility 8 are in a call state, and the IPPV program name and the viewer ID are transmitted. The billing equipment 8 accepts the information, investigates the contents of the viewer's contract, credit information, and the like. If it is determined that the IPPV program can be viewed, the charging facility 8 transmits the descramble key information to the modem during the call state. Sent to 26 guess. The modem 26 stores the descramble key information in the memory 25 of the data processing unit 23.

On the other hand, when broadcasting the IPPV program, the broadcaster scrambles the IPPV program and inserts scramble data into a period corresponding to the vertical retrace period of the IPPV program as shown in FIG. Broadcasting is performed from a broadcasting facility 9 via a broadcasting satellite 10.

The viewer demodulates the scrambled data in the receiving section 21 and outputs the demodulated data to the data processing section 23.
In step 3, it is determined whether or not the key information matches the descrambling key information. If the key information matches, the operation of the descrambling circuit is turned on, and the IPPV program is viewed on the television 2 as a signal for viewing. On the other hand, if the scrambled data and the descramble key information do not match, the IPPV program cannot be descrambled, and the scrambled IPPV program is sent to the television or the IPPV program is muted for viewing. Ban. Although the IPPV program has been described above, the TPV program can also be viewed using a substantially similar system.

FIG. 4 illustrates the operation of the accounting system according to the present embodiment. First, when a viewer subscribes to a broadcast billing system, he or she requests a selection of a billing system for program provision set by a broadcaster, but pays monthly (S3).
0), or pay by TPV per hour of watching the program (S2
0), select whether to pay with a fixed viewing fee IPPV per program (S10), make a contract for viewing and payment, open an account for automatic transfer of the viewer, and sign (S40). . It should be noted that the monthly fee and the IPPV are mixed, or the monthly fee is selected in various manners, such as adding a viewing fee per program to the minimum fee in a plurality of stages, and selecting a viewing fee per hour according to the time zone. Although contracts and the like are possible and mainly depend on the broadcast form of the broadcaster, in the present embodiment, three types of contracts will be described as the simplest examples.

First, when the contract is made on a monthly basis, it is determined whether or not the billing information has been sent via the modem 26 on a predetermined day of the month (S31). If so, the bill is paid from the billing account (S50), and the process ends and the process returns to the next month.

Next, when contracting as a TPV program,
A specific channel is designated and demodulated by the receiving unit 21. To count the viewing time, the specific channel is turned on, scrambled data is detected, and the data
6 is determined to match or not match the descrambling key information received from No. 6, and if they match, the TPV program is descrambled by the descrambling circuit 22 to start viewing (S21), and has conventionally been stored. The time counter is counted up while being superimposed on the time.

Thereafter, at every predetermined period, the TPV program name, the viewing time, and the viewer ID are paired and converted into data of viewing information, and transmitted to the modem 26. The modem 26 enters a communication state with the charging facility 8 via the PHS terminal 34,
The data of the previous viewing information is transmitted. The billing facility 8 calculates the billing from the data of the viewing information ahead of it, and calculates
6 and the modem 26 transmits the billing amount to the data processing unit 2.
3 and the data processing unit 23 superimposes the charge amount on the TPV program of the output signal of the descramble circuit 22,
It is displayed on the television 2 to obtain the viewer's confirmation (S23). When the viewer operates the confirmation button, the modem 26 sends confirmation data to the billing facility 8, thereby terminating the call state. At this time, of course, a plurality of TPV programs may be collected. Thereafter, the broadcaster subtracts the charged amount from the viewer's billing account (S50), ends, and prepares for the next regular billing collection date.

When the PHS terminal 34 ends the call state, the socket 27 is not mounted, and the PHS terminal 34 can be used freely as a normal PHS terminal.

When the user wants to view the program as an IPPV program, it notifies the billing facility 8 of the request to view the IPPV program based on the guide broadcast of the IPPV program by the broadcaster (S11). As described above, the more convenient method of the notification is that, during the guide broadcast of the IPPV program, during the display of the desired viewing of the television 2, the viewing polygon is indexed on the television screen and the reset is pressed, and the modem 26 is reset. A PHS terminal is connected via the PHS terminal, the IPPV program to be viewed and the ID of the viewer are notified as a communication state with the charging facility 8, and key information for descrambling is stored in the memory 25 of the data processing unit 23. When a specific channel is selected when the IPPV program is broadcast and the IPPV program is selected (S1)
2) detecting the scrambled data in the IPPV program,
The data processing unit 23 compares it with the descramble key information,
If they match, the descrambling circuit 22 descrambles the IPPV program and allows the television 2 to view the program.

When the IPPV program has been watched (S
13) If the TV screen for the guidance of the charging process is displayed on the last screen of the IPPV program, and then press the confirmation button, the data processing unit 23 finishes viewing the IPPV program name and the viewer ID. Viewing information including the information of
The modem 26 is connected to the PHS terminal 34, and the modem 26 is connected to the billing facility 8 and communicates with the billing facility 8 to notify viewing information including the IPPV program name, the viewer ID, and information indicating that viewing has been completed as billing information. (S14).

The broadcaster collects a fee from the viewer's billing account (S50), and ends the process of viewing and charging the IPPV program.

In the above-mentioned flowchart, when an IPPV program is to be ordered later than the announcement, the IPPV program and the ID of the viewer may be notified to the charging facility 8 via the PHS terminal 34. The descramble key information is stored in the memory 25 in the same procedure. In addition, if the fee to be paid by the viewer is managed by the billing equipment 8 based on the notification of the billing information from the viewer, the monthly fee, the TPV program,
No matter which of the IPPV programs is missed.

In the above-mentioned flowchart, the PHS terminal has been described as being usable independently, but as a matter of course, as shown in FIG.

[Second Embodiment] A second embodiment of the present invention will be described. For pay programs and the like, charging information is communicated from the tuner 1 to the charging equipment 8 of the broadcaster so that the programs can be viewed. One of the mechanisms may be as described above.

At this time, the billing information is sent from the modem output mechanism of the tuner 1.

PHS with tuner 1 and connection cable 11
When the tuner 1 transmits the billing information by connecting to the interior unit 4, the PHS interior unit 4 performs a connection process to the billing facility 8 via the BS 5.

At this time, when the wired line 7 is in the BUSY state, the BUSY information is notified to the tuner 1 and the tuner 1 waits for a reconnection request. At that time, the call processing is repeatedly performed from the modem at regular time intervals.

After the wired line connection, the PHS interior unit 4 connected to the charging facility 8 sends a connection completion notification to the tuner 1 and starts charging information transmission procedure.

The tuner 1 sends the billing information to the PHS interior unit 4 and sends the billing information to the billing facility 8 via the BS 5. The billing facility 8 performs a prescribed process and returns the result to the tuner 1.

The tuner 1 receives the notification of the billing result from the billing facility 8, so that the pay information can be viewed. That is, when the broadcaster notifies the user of the viewing of the IPPV program of the pay program, the billing process is terminated and the key information of the descrambling is notified for the first time, and the key information is stored in the memory 25. The descrambling is enabled at the time of broadcasting the IPPV program, and there is no need for subsequent billing notification. Therefore, even if the viewer places an order for the IPPV program, but fails to view the program due to circumstances, it is collected from the charging account.

According to the above embodiment, it is not necessary to lay a telephone line, and the tuner 1 is provided with a socket for connecting to the PHS terminal. .

The above-mentioned PHS terminal may be a DPC mobile phone as long as data communication is possible, or a W-CDMA mobile terminal used in a future mobile communication system. Billing management can be performed by a similar operation. In the case of a W-CDMA mobile terminal, the communication speed is high, so that it can cover the majority of viewers and contribute to business expansion by broadcasters.

[0055]

[Explanation of Effect] By communicating a modem signal from a tuner with a mobile device such as a PHS line, it is not necessary to lay an existing home modular.

Further, since communication is performed using the existing modem signal between the tuner and the billing facility of the broadcaster, there is no need to consider error control or the like. Also, in the home equipment, the connection between the tuner and the PHS built-in unit can be arbitrarily connected before and after the broadcast of the program to be watched, and the billing information and the confirmation thereof can be transmitted and received. Since a normal PHS system can be used, no blank time is generated for the operation of the PHS system, which is convenient.
