1. A method of generating a program signal stream comprising:

  • creating a program signal stream comprising a serial sequence of programs;

    inserting, by a processing device, into the program signal stream, a first rights-related segmentation message defining first rights-related information concerning a right to store an entire expanse of the program signal stream by a program distribution system, in a first location prior to a start of the expanse;

    inserting, by the processing device, into the program signal stream, a second rights-related segmentation message defining second rights-related information for the program distribution system concerning the content of the entire expanse, the second rights-related information being different from the first rights-related information, in a second location after a start of the expanse and before an end of the expanse, wherein the respective first and second locations of the first and second rights-related segmentation messages are based, at least in part, on the first and second rights-related information; and

    transmitting the program signal stream including the expanse and the first and second segmentation messages to a program content distribution system.
