Abstract

A program material screening device is provided whereby the owner of a program signal receiving device such as a telephone, television, radio, VCR, or the like may automatically and selectively prevent the reception and replay by the receiving device of unwanted transmissions. The screening device is capable of recognizing non-interfering material content signals co-transmitted with the program signals received by the receiving device, and is capable of automatically disabling the receiving device in response to recognition of the material content signal.

Claims

1. A method for selectively screening program material comprising

(1) transmitting to one or more receiver devices a program material signal which is electronically detectable by each receiver device, each receiver device being capable of recognizing and replaying said program material signal in a humanly perceivable form,

(2) supplementing the program material signal with a material content signal electronically detectable by a program material screening device, wherein said material content signal does not interfere with transmission of the program material signal or reception thereof by a receiver device not connected to a program material screening device, and

(3) connecting at least one of said one or more receiver devices to a program material screening device such that upon detecting said material content signal, said program material screening device, on the authorization of the receiver device user, automatically selectively disables at least one of the one or more receiver devices connected to a program material screening device from receiving and/or replaying said program material signal.

4. A method according to claim 1, wherein said receiver device is a telephone, a video cassette recorder, a television, a radio, a record player, a tape player, a film projector, or a computer.

5. A method according to claim 1, wherein said program material signal is embodied in radio signals, television signals, telephone signals, satellite transmissions, wire transmissions, microwaves, infrared radiation, or is recorded on magnetic tape, records, microchips or laser readable discs.

6. A method according to claim 1, wherein said material content signal is embodied in radio signals, television signals, telephone signals, satellite transmissions, wire transmissions, microwaves, infrared radiation, or is recorded on magnetic tape, records, microchips, or laser readable discs.

7. A method according to claim 1, wherein said material content signal is transmitted simultaneously from the same source as the program material signal.

8. A method according to claim 1, wherein said material content signal is transmitted from a different source than the program material signal.

2. In a communication system wherein a program material signal is transmitted to one or more receivers capable of recognizing and replaying said program material signal in a humanly perceivable form, the improvement wherein (1) said program material signal is supplemented with a material content signal which is detectable by a program material screening device and which does not interfere with transmission of said program material signal or reception thereof by a receiver not connected to a program material screening device, and (2) at least one of said receivers is connected to a program material screening device capable of automatically preventing, at the selection of the receiver user, reception and/or replay of the program material signal by the receiver in response to detection of the material content signal by said screening device.

9. The improvement according to claim 2, wherein said receivers are telephones, video cassette recorders, televisions, radios, record players, tape players, film projectors, or computers.

10. The improvement according to claim 2, wherein said program material signal is embodied in radio signals, television signals, telephone signals, satellite transmissions, wire transmissions, microwaves, infrared radiation, or is recorded on magnetic tape, records, microchips or laser readable discs.

11. The improvement according to claim 2, wherein said material content signal is embodied in radio signals, television signals, telephone signals, satellite transmissions, wire transmissions, microwaves, infrared radiation, or is recorded on magnetic tape, records, microchips, or laser readable discs.

12. The improvement according to claim 2, wherein said material content signal is transmitted simultaneously from the same source as the program material signal.

13. The improvement according to claim 2, wherein said material content signal is transmitted from a different source than the program material signal.

3. A program material screening device adapted to be connected to a program material receiver capable of recognizing and replaying a transmitted program material signal in humanly perceivable form, comprising (a) recognition means for detecting any supplemental material content signal transmitted with said program material signal and (b) disabling means for automatically selectively preventing, at the selection of and under the direct authorization of the receiver user, replay of the program material signal by the receiver upon detection of a material content signal by said recognition means.

14. A screening device according to claim 3, wherein said receiver is a telephone, video cassette recorder, television, radio, record player, tape player, film projector, or computer.

15. A screening device according to claim 3, wherein said program material signal is embodied in radio signals, television signals, telephone signals, satellite transmissions, wire transmissions, microwaves, infrared radiation, or is recorded on magnetic tape, records, microchips or laser readable discs.

16. A screening device according to claim 3, wherein said material content signal is embodied in radio signals, television signals, telephone signals, satellite transmissions, wire transmissions, microwaves, infrared radiation, or is recorded on magnetic tape, records, microchips or laser readable discs.

17. A screening device according to claim 3, wherein said material content signal is transmitted simultaneously from the same source as the transmitted program material signal.

18. A screening device according to claim 3, wherein said material content signal is transmitted from a different source than the transmitted program material signal.

19. A telephone message screening device adapted to be connected in series between a telephone message source and a telephone, comprising (a) recognition circuitry capable of detecting one or more series of incoming dual tone multi-frequency signals prefacing or comprising a part of an incoming telephone message and (b) disconnect circuitry connected to said recognition circuitry such that on detection of one or more series of incoming dual tone multi-frequency signals by said recognition circuitry, said disconnect circuitry automatically prevens or interrupts said telephone from receiving telephone messages.

20. A telephone message screening device as defined in claim 19, wherein said disconnect circuitry prevents or interrupts telephone messages in response to some but not all of the series of incoming dual tone multi-frequency signals detected by said recognition circuitry.
