发明名称 Use of messages in or associated with program signal streams by set-top terminals
摘要 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.

主权项 1. A method of operating a receiving device comprising: receiving a 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; disregarding the at least one embedded decoy message based, at least in part, on content of the at least one embedded decoy message; decrypting the at least one segmentation message; identifying the expanse by the receiving device based, at least in part, on the at least one decrypted segmentation message; inserting advertising in the expanse; and causing display of at least a portion of the program signal stream including the advertising.
