Use of messages in or associated with program signal streams by set-top terminals
First Claim
1. A method of operating a communications system comprising receiving devices coupled to respective display devices at user locations, the method comprising:
- broadcasting a program signal stream to a receiving device, the program signal stream comprising at least one embedded, encrypted segmentation message to indicate an expanse of a portion of the program signal stream for insertion of advertising, and at least one embedded decoy message;
decrypting the at least one segmentation message by the receiving device;
identifying the expanse by the receiving device based, at least in part, on the at least one decrypted segmentation message; and
inserting advertising in the expanse by the receiving device.

Abstract
Methods of operating a communications system comprise inserting advertising in a program stream by a receiving device based, at least in part, on an embed, encrypted segmentation message embedded in the program stream. The at least one segmentation message defines an expanse of the program stream to receive the advertising. At least one embedded decoy message is included in the program stream, as well. The receiving device, which may be a set-top terminal, for example, is coupled to a display device, such as a television, at a user location. A method of operating a receiving device coupled to a display device at a user location is also disclosed, comprising programming the receiving device to record a program and recording the program based, at least in part, on at least one segmentation message in a program stream. Systems are disclosed, as well.

11. A communications system comprising:
a first processor programmed to;
cause broadcast of a program signal stream including at least one embedded, encrypted segmentation message to indicate an expanse of a portion of the program signal stream for insertion of advertising, and at least one decoy message; and
a receiving device to be coupled to a display device at a user location, the receiving device being coupled to the first processor to receive the program signal stream;
wherein;
the receiving device comprises;
an interface to receive the program signal stream;
a second processor coupled to the interface; and
memory to store advertising, coupled to the second processor; and
the second processor is programmed to;
decrypt the at least one encrypted segmentation message;
identify the expanse of the program signal stream based, at least in part, on the at least one decrypted segmentation message;
retrieve advertising from the memory; and
insert the advertising into the expanse of the program signal stream.- View Dependent Claims (12, 13, 14, 15)

16. A method of operating a communications system comprising set-top terminals coupled to respective televisions at user locations, the method comprising:
-
broadcasting a program signal stream to a set-top terminal, the program signal stream comprising at least one embedded, encrypted segmentation message to indicate an expanse of a portion of the program signal stream for insertion of advertising, and at least one embedded decoy message;
decrypting the at least one segmentation message by the set-top terminal;
identifying a start of the expanse based, at least in part, on the at least one segmentation message;
identifying an end of the expanse based, at least in part, on the at least one segmentation message;
disregarding the at least one segmentation message while identifying the start and the end of the expanse; and
inserting advertising in the expanse by the set-top terminal.

23. A receiving device to receive a program signal stream comprising at least one program and at least one message, the receiving device to be coupled to a display device, the receiving device comprising:
-
an interface to receive the program signal stream and to provide the program signal stream to the display device;
a processor coupled to the interface, wherein;
the processor is programmable by a user to record the program; and
the processor is programmed to record the at least one program based, at least in part, on the at least one message; and
memory coupled to the processor to store the recorded program. - View Dependent Claims (24, 25, 26, 27, 28)
