Abstract
The invention relates to the processing of digital data which is transmitted by broadcasters of television programs for receipt by users of a broadcast data receiver which includes decoding the transmitted data and then processing the decoded data to generate video and/or audio displays on a television set or other form of display screen in the form of a television program. The television system allows the user to select to monitor a selected program for designated criteria and, if the criteria is/are detected, the system activates an alert for the user, stores the data for the selected program or displays the selected television program thereby allowing the user to be aware of a designated occurrence in the television program even though they were not previously watching the television or were watching another program.
