Abstract

A method of triggering the recording of a programming stream includes: receiving a request to monitor for an unscheduled event; determining search strings associated with the unscheduled event; monitoring a programming stream; analyzing closed captioning information contained in the programming stream to determine the occurrence of the search strings; and recording the programming stream upon the occurrence of the search strings.
