Initial reporting of remotely generated data
First Claim
1. A device for reporting data to a central station, said device comprising:
- memory means for storing data;
control means for causing said stored data to be initially reported in response to the storage in the memory means of at least a predetermined minimum amount of said data, wherein said control means comprises;
clock means for indicating elapsed time;
means for processing said elapsed time indication to define time slots within which to make said reports;
means for assigning a predetermined time slot for said reporting of said stored data following the storage in the memory means of at least said predetermined minimum amount of said data, with said time slot being assigned in accordance with predetermined criteria;
means for storing said predetermined criteria; and
means for changing said stored predetermined criteria.

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 stored data was successfully reported to the central station; and tries again to report the stored data when the stored data was not successfully reported to the central station. Upon trying again the control unit causes the stored data to be reported in a different predetermined time slot than that used for the last previous unsuccessful report.

4. A device for reporting data to a central station, said device comprising:
-
memory means for storing data, and control means for causing said stored data to be initially reported in response to the storage in the memory means of at least a predetermined minimum amount of said data, wherein said control means comprises; clock means for indicating elapsed time; means for processing said elapsed time indication to define a recurring group of time slots within which to make said reports; means for assigning a predetermined time slot within said group for said reporting of said stored data following the storage in the memory means of at least said predetermined minimum amount of said data, with said time slot being assigned in accordance with predetermined criteria; means for monitoring whether said stored data was successfully reported to said central station; and means for trying again to cause said stored data to be reported, when the previous try to report said stored data to the central station was unsuccessful, wherein said means for trying again includes means for causing said stored data to be reported in a different predetermined time slot within said group than that used for the last said unsuccessful report. - View Dependent Claims (5, 6, 7)

13. A system including a plurality of devices for respectively reporting data generated at different locations to a central station, wherein an individual said device comprises:
-
memory means for storing said data; and control means for causing said stored data to be initially reported in response to the storage in the memory means of at least a predetermined minimum amount of said data, wherein control means comprises; clock means for indicating elapsed time; means for processing said elapsed time indication to define a recurring group of time slots within which to make said reports, wherein the number of time slots in the group is less than the number of said devices in the system; and means for assigning a predetermined time slot within said group for said reporting of said stored data following the storage in the memory means of at least said predetermined minimum amount of said data, with said time slot being assigned in accordance with predetermined criteria, and with different time slots being assigned for different devices, but with some time slots being assigned to more than one said device; means for monitoring whether said stored data was successfully reported to said central station; and means for trying again to cause said stored data to be reported, when the previous try to report said stored data to the central station was unsuccessful, wherein said means for trying again includes means for causing said stored data to be reported in a different predetermined time slot within said group than that used for the last said unsuccessful report. - View Dependent Claims (14, 15, 16, 17, 18)

19. A device for reporting data to a central station, said device, comprising:
-
memory means for storing data; and control means for causing said stored data to be initially reported in response to the storage in the memory means of at least a predetermined minimum amount of said data, wherein the control means comprise means for storing an indication of a predetermined minimum count of the amount of unreported data that must be stored in the memory means in order to trigger said reporting of said stored data; means for maintaining a count of the amount of unreported data stored in the memory means; and means for triggering said report upon determining that the maintained count of unreported data stored in the memory means reaches said stored predetermined minimum count. - View Dependent Claims (20, 21)
