Abstract
Program data is provided in association with a main audio program to a receiver of a duplicative radio broadcasting system wherein a duplicative broadcast (such as a hybrid IBOC broadcast) includes a primary channel and a backup channel in a predetermined frequency allocation. Both the primary channel and the backup channel transmit the main audio program, and the primary channel transmits program data not included in the backup channel. The receiver includes an audio output for reproducing the main audio program and a display for displaying the program data. The method includes recurrently compiling a program event list of the program data corresponding to a current program event and a plurality of upcoming program events. The program event list is recurrently transmitted within the primary channel. The receiver recurrently recovers the program event list and stores the program data in a memory. The program data of the current program event is displayed. The audio output is blended from the primary channel to the backup channel in response to detection of an impaired primary channel. The display is updated to show program data of one of the upcoming program events from the memory during impairment of said program data in said primary channel.
