In a broadcast system such as a direct-to-home satellite system, program guide information for different time periods is transmitted on different carousels (e.g., one for 0-6 hours from current time, one for 6-24 hours, one for 24-72 hours, etc.) and broadcast on all transponders. Guide information for time periods in the near future is transmitted more frequently (i.e., less information per carousel) than guide information for later time periods. The receiving IRD sets a bit mask to indicate which carousel or carousels it requires and downloads them in serial or parallel. Updated information is never missed because it is given a bit pattern that is never screened by the mask. Further, the IRD can download the program guide information in the background (i.e., while displaying video) because it does not need to tune to a different transponder.
