Abstract

Methods of operating a communications system comprise, in one example, inserting advertising in a program stream by a receiving device based, at least in part, on an encrypted segmentation message embedded in the program steam. 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. In one example, 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.

4. The method of claim 3, further comprising;

setting a recording end clock time for the selected program based on a first program end clock time defined by the program listing;

wherein the at least one message contains a second program end time of the selected program, the second program end time being in units of time with respect to progression of the program signal stream, from receipt of the message to an end of the selected program in the program stream, the method further comprising;

comparing the second program end time, in units of time, contained in the at least one message to the recording end time;

adjusting the recording end time of the selected program to the second program end time, if the recording end time is different than the second program end time; and

ending recording of the selected program at the second program end time, if the recording end time has been adjusted.

5. The method of claim 4, wherein the at least one message comprises a single message defining the second program start time and the second program end time, the method comprising:

receiving the program signal stream including the single message.

6. The method of claim 4, further comprising:

after starting to record the selected program, receiving at least one second message in the program signal stream, the at least one second message defining a second program end time by indicating an amount of time until the end of the program, in units of time with respect to progression of the program signal stream, from receipt of the message to an end of the selected program in the program stream; and

ending recording of the program at the second program end time, in units of time, contained in the at least one second message.

7. The method of claim 6, further comprising:

after starting to record the selected program;

receiving at least one second message defining a start time for unscheduled content of the selected program, wherein the unscheduled content follows the first program end clock time, the at least one second message being received prior to the scheduled end time, in the program signal stream;

continuing to record the selected program after the scheduled end time;

while recording the selected program, receiving at least one third message defining an end time for the unscheduled content of the selected program, the end time for the unscheduled content being after the first program end clock time of the selected program, the at least one third message being received prior to the end time of the unscheduled content, in the program signal stream; and

ending recording of the selected program at the end time of the unscheduled content defined by at least one of the at least one third message.

8. The method of claim 7, wherein the selected program is a sporting event and the unscheduled content comprises overtime of the sporting event.

9. The method of claim 7, wherein the at least one third message comprises at least one fourth message defining at least one respective expected end time of the unscheduled content and at least one fifth message defining an actual end time of the unscheduled content, the method comprising:

receiving the at least one fourth message prior to receiving the at least one fifth message; and

ending recording of the selected program at the actual end time defined by the at least one fifth message.

10. The method of claim 1, wherein the originator comprises a program origination system.

11. The method of claim 1, comprising receiving the program signal stream, including the at least one message, via a cable television network.

12. A receiving device to receive a program signal stream comprising:

an interface to receive a program signal stream comprising at least one program, the program signal stream comprising at least one message containing a first program start time for a selected one of the at least one programs, the first program start time being in units of time with respect to progression of the program signal stream, from receipt of the message to a start time of the selected program in the program stream, wherein the program signal stream including the at least one message is received from a same originator;
