Abstract
A system and method for localizing an aggregated electronic program guide (EPG) schedule covering a plurality of service environments includes an information filter located at the subscriber's set-top box conditioned to recognize which schedule information is relevant to the viewer's service environment. Only schedule information corresponding to the viewer's own service environment is stored in the EPG's schedule database. The result is an electronic program schedule that is tailored to the viewer's specific service environment without the use of costly equipment on the transmission side of the program schedule feed.
