Abstract
An electronic program guide executing in a set top box provides real-time guide EIT information to users for periods beyond the six hours of conventional systems. Each transport providing information to the set top box contains a predetermined number of hours of full EIT data and a predetermined number of days of sparse EIT data. The sparse EIT data allows users to see information for programming in real time days into the future without having to tune to a different transport.
