Abstract
A device for reporting remotely stored data is coupled to a descrambler in an impulse pay-per-view television system for storing and reporting data pertaining to subject matter descrambled by the descrambler, such as identification of each impulse pay-per-view program that is descrambled. The descrambler receives scrambled television programs over a data link from a central station. The reporting device is coupled to the central station by telephone lines for reporting the stored data to the central station. The reporting device includes a memory at the remote location for storing the generated data; and a control unit for causing the stored data to be initially reported in response to the storage of at least a predetermined minimum amount of data. The control includes a clock for indicating elapsed time; and the control unit processes the elapsed time indication to define time slots within which to make the reports, with predetermined time slots for the reporting of the stored data following the storage of at least the predetermined minimum amount of data being assigned by the control means in accordance with stored predetermined criteria. The control unit monitors whether the sto…
