ABSTRACT:
Scheduling functionality is employed at a head-end site to update schedules used by a plurality of respective client devices to define the recording of media presentation events. The scheduling functionality operates by: compiling a master list of unique entries culled from the plurality of schedules; determining whether any entries in the master list require updating; and updating, based on the determining, at least one of the plurality of schedules. The scheduling functionality helps reduce the amount of redundant processing operations involved in updating the plurality of schedules, and therefore provides an efficient technique for updating the schedules.
