Abstract
Systems and methods described herein related to dynamically adjusting levels of detail of content event descriptions contained in an EPG according to a user's behavior. Predictions are made based on the user's behavior as to which content events the user may desire to see a more detailed description for. Rankings are assigned to future events based on the user's behavior. When it comes time to update the EPG (i.e., download event descriptions for one or more new time periods), the rankings are utilized to determine which events should have event descriptions of a greater detail stored for them. Memory is more efficiently utilized by having high level event descriptions available for events in which the user is likely to be interested and low level event descriptions available for events in which the user is probably not interested.
