Abstract

PURPOSE:To find the charge for video software by projecting the charging data sent from a CATV center on a television receiver CONSTITUTION:The charging data sent by a cable 1 are demodulated by a demodulation section 14. When the display of the charging data is directed by an input section 13, the charging data of the demodulation section is stored in a storage section 12 and the stored data are transformed to character patterns by a character generator 7. A complex video signal generation section 3 generates a complex video signal which is displayed on a television receiver 6 through a video switching section 4. When the toll program channel is selected and received from the input section, the charging data of corresponding TV programs from the charging data of the storage section are stored in a memory section 16. On the other hand, when the prescribed date comes, the telephone line is connected by dialing the CATV center from the input section and the data of the total payment of the memory section are modulated by a reading MODEM section 16 and sent to the CATV center through a network control section 9.

Connected to an ATV center to deliver billing data and TV programs to homes. A CATV converter 2 receives the data transmitted by the cable, selects the channel of the television signal, detects it, and outputs it as a composite video signal. Reference numeral 13 is an input unit for instructing display of charging data on the display unit, selecting a program to be watched and dialing. 14 is F
The SK demodulator demodulates the billing signal received by the CATV converter 2. A storage unit 12 stores the charging data of the FSK demodulation unit 14. Reference numeral 16 is a memory unit, and when a pay program channel is selected from the input unit 13 and received, the storage unit 12
The charge data of the corresponding TV program is stored in the memory unit based on the charge data. A calculation unit 11 calculates the total amount by calculating the amount in the memory unit 16 when the input unit 13 is instructed to display the payment amount. A timer 5 counts the time. Reference numeral 7 is a character generator which converts billing data into a character pattern for displaying. Reference numeral 3 denotes a composite video signal generator which generates the signal from the character generator 7 into a composite video signal. Reference numeral 4 is a video switching unit, which is a CATV converter 2
And the composite video signal from the composite video signal generator 3 is switched. A television receiver 6 displays the signal from the video switching unit 4. 8 is a modem section, which is a memory section 16

The FSK demodulation unit 14 receives the (SK modulated signal). FSK
Since the demodulation unit 14 is always operating and billing data is sent at a predetermined time, it receives it and stores it in the storage unit 12. If the user wants to know the price of the TV program, he / she gives an instruction to display a charge from the input unit 13. The control unit 15 reads the charging data (FIG. 2) from the storage unit 12, and the character generator 7
Is converted into a character pattern, and the composite video signal generator 3 generates a composite video signal. Then, the video switching section 4 is switched to the charge display side. Thereby, the television receiver 6 displays the signal of the composite video signal generation unit 3.

When an operator wants to watch a desired program,
The corresponding channel is designated from the input unit 13. The control unit 15 sends a channel selection signal to the CATV converter 2,
The tuner of the TV converter 2 is switched to the designated station, and the video switching unit 4 is switched to the television display side. Thereby, the television signal from the CATV converter 2 is displayed on the television receiver 6. On the other hand, the control unit 15 uses the input unit 13
Based on the channel selection signal, the corresponding billing data is read from the data stored in the storage unit 12, and the count data of the clock unit 11 is stored in the memory unit 16. For each channel selection signal from the input unit 13, the control unit 15 extracts the corresponding charge from the charging data in the storage unit 12 and writes it in the memory unit 16 (FIG. 3). The calculation unit 11 adds the amount of money for each program in the memory unit 16 and writes the total amount of money in the memory unit 16.
Instead of switching between the television signal and the billing data by the video switching unit 4, the two signals may be mixed or superimposed. When the operator wants to know the total payment amount at the present time, the operator gives an instruction to display the payment amount through the input unit 13. The control unit 15 switches the video switching unit 4 to the charge display, reads the payment fee data from the memory unit 16,
The character generator 7 converts the character pattern into a character pattern, the composite video signal generator 3 generates a video signal, and the television receiver 6
To display.

[0009]

As described above, according to the present invention, the charge for each TV program can be known before the channel is selected, and the total amount of the charge seen so far can also be known. The effect of being able to do is great.
