Method and system for subscription television billing and access
First Claim
1. A billing system for obtaining billing information regarding programs actually viewed by a subscriber of a pay television system comprising:
- means for transmitting at a predetermined carrier frequency a scrambled television program signal containing a block of television program material and an identification code unique to the block of program material being transmitted;
means at a subscriber station for selectively receiving the transmitted program signal and for selectively unscrambling the program signal to permit viewing of the block of program material being transmitted in response to subscriber action indicating acceptance for viewing of the block of program material;
means for detecting the identification code in the program signal received at the subscriber station and for temporarily storing a program identification code for subsequent transmission as an electrical signal in response to the detected identification code and to the subscriber action indicating acceptance for viewing of the block of program material; and
means connected to said detecting and storing means for selectively accessing the program identification code stored at the subscriber station on other than a real time basis and for transmitting the stored program identification signal to a remote location in response to a command signal received from the remote location to thereby provide billing information at the remote location as to programs actually viewed by the subscriber.

Abstract
A subscription television system and method in which billing information regarding programs actually viewed by a subscriber of the system is accumulated over non-dedicated telephone lines. A scrambled television program signal containing a block of television program material and a program identification code unique to the block of program material is transmitted at a predetermined carrier frequency. The codes are preferably included in the vertical retrace interval of the video portion of the program signal and the transmitted program signal is selectively received at a subscriber station and selectively unscrambled to permit viewing of the block of program material being transmitted in response to subscriber action indicating acceptance for viewing of the block of program material. The program identification code in the program signal received at the subscriber station is detected and stored for subsequent transmission as an electrical signal in response to the subscriber action indicating acceptance for viewing of the block of program material.
The program identification code stored at the subscriber station is selectively accessed from a remote location over telephone lines on other than a real time basis (e.g., a periodic basis) to thereby provide billing information at the remote location as to programs actually viewed by the subscriber. The subscriber can thus be billed monthly or on some desired periodic basis for programs actually viewed during the preceding period.

8. A method for billing a subscriber of a pay television system for programs actually viewed by the subscriber at a subscriber station comprising the steps of:
-
transmitting at a predetermined carrier frequency a scrambled television program signal that includes an identification code unique to a block of program material being transmitted; selectively receiving the transmitted program signal at the subscriber station and selectively unscrambling the received signal in response to subscriber action indicating acceptance for viewing of the block of program material; detecting the identification code in the program signal received at the subscriber station and temporarily storing a program identification code for billing purposes in response to the action of the subscriber indicating acceptance for viewing of the block of program material being received; selectively accessing the subscriber station from a remote location to obtain access to each program identification code stored at the subscriber station; and billing the subscriber in accordance with the stored program identification codes accessed from the remote location.

11. In a pay television system in which television program signals are transmitted to subscribers in a scrambled form and the subscribers are billed a per program charge for programs viewed, a subscriber billing system comprising:
-
means at a location remote from the subscriber location for inserting a program identifying signal into the scrambled program signal for transmission thereof with the program signal; means at the subscriber location for receiving the scrambled program signal, including the program identifying signal; means at the subscriber location for generating an accept signal indicating acceptance of a program signal for viewing by the subscriber; and
,memory means at the subscriber location for storing a billing signal that identifies the program accepted for viewing in response to both the received program identifying signal and the accept signal, billing signals identifying the programs accepted for viewing thereby being stored at the subscriber location for subsequent retrieval in order to bill the subscribers on the basis a per program charge for programs accepted for viewing. - View Dependent Claims (12, 13, 14)
