Abstract

Method and apparatus are provided for controlling and delivering television programming from a control station to one or more substations, which in turn transmit television programming to remote receiving locations on a pay-per-view basis. Programming is originated and delivered from the control station to record and playback devices at the substation. The record, playback and transmission of the programming at the substation is remotely controlled from the control station in accordance with schedule information generated at the control station. Similarly, scrambling and anti-copy devices at the substation can be remotely controlled in accordance with the schedule information.

Claims

1. An apparatus for controlling and delivering television programming to one or more television substations from a control station, wherein each substation transmits television programming on one or more channels in a scrambled form and a program schedule on a separate barker channel over a multi-channel cable or over-the-air distribution system to all of a plurality of remote subscriber receiving locations on a pay-per-view basis, comprising:

a) means for receiving television programming at the substation;

b) a plurality of television program record and playback means at the substation;

c) first audio and video transmitting means at the control station for transmitting television programming to the substation to be recorded on the record and playback means;

d) second audio and video transmitting means at the substation for transmitting the television programming from the record and playback means over the one or more channels to the remote subscriber locations, the second transmitting means including one or both of audio and video signal scrambling means on one or more of the channel outputs;

e) first computer means at the control station for generating record schedule information and playback schedule information;

f) second computer means at the substation;

g) data communications means for transferring signals indicative of the record and playback schedule information between the first and second computer means; and

h) control interface means at the substation connected to the second computer means operative to switch the record and playback means, the second transmitting means and scrambling means in response to the signals indicative of the record and playback schedule information from the second computer, wherein

the record and playback means at the substation are controlled in accordance with the record and playback schedule information transmitted from the control station, and

i) means at the substation for selectively enabling descrambling of the television programming to individual subscriber receiving locations in response to a request from the individual subscribers for a particular television program on a pay-per-view basis.

2. The apparatus of claim 1, wherein the second computer means provides a signal indicative of the playback schedule to the second transmitting means for transmission on the separate barker channel.

3. The apparatus of claim 1, wherein the subscriber receiving locations are equipped with one or both of addressable video and audio signal descrambling means, which descrambling means can be selectively enabled by the substation in response to a request for a particular television program on a pay-per-view basis from the subscriber.

4. The apparatus of claim 3, wherein the second transmitting means includes anti-video copying means on the one or more channel outputs, which anti-video copying means are connected to the control interface means for remote control from the second computer means in accordance with the playback schedule information.

5. The apparatus of claim 1, wherein the record and playback means at the substation comprises a plurality of video tape or video cassette recorder and players.

6. The apparatus of claim 1, wherein the first transmitting means at the control station is operative to transmit television programming to the substation by satellite feed.

7. The apparatus of claim 2, which further comprises means for generating text and graphics at one or both of the control station and substation, which means is connected to the one or both of the first and second computer means and is operative to combine text and graphics with the playback schedule for transmission on the barker channel by the second transmitting means.

8. A method of controlling and delivering programming to a television transmission substation from a control station, wherein the substation transmits television programming in a scrambled form on one or more channels and a program schedule on a separate barker channel over a multi-channel cable or over-the-air distribution system to all of a plurality of remote subscriber receiving locations on a pay-per-view basis, comprising the steps of:

a) transmitting television programming from the control station for reception on receiving means at the substation;

b) recording the television programming on one or more audio video record and playback means at the substation;

c) generating record schedule information on a first computer means at the control station;

d) generating playback schedule information on the first computer means at the control station;

e) transmitting data signals indicative of the record and playback schedule information and of the playback schedule from the control station to a second computer means at the substation;

f) controlling the record and playback of the audio video record and playback means at the substation in accordance with the record and playback schedule information transmitted from the control station;

g) transmitting the television programming in a scrambled form from the substation to the subscriber receiving locations in accordance with the playback schedule information on the one or more channels;

h) transmitting information indicative of the playback schedule in the form of one or both of text and graphics from the substation to the subscriber receiving locations on the separate barker channel; and

i) selectively enabling descrambling of the television programming from the substation to individual subscriber receiving locations in response to a request from the individual subscribers for a particular television program on a pay-per-view basis.

9. The method of claim 8, wherein the control station transmits television programming to the substation by satellite feed.

10. The method of claim 8, wherein the control station transmits television programming, record schedule information and playback schedule information to a plurality of substations on an individualized basis.

11. The method of claim 8, wherein the substation generates information indicative of buy rates of the television programming by the subscribers for a given schedule period, transmits that buy rate information to the control station, and wherein the control station varies the record and playback schedule information for the substation for a subsequent schedule period in response to the buy rate information.
