An apparatus and method for processing additional information in a display device. It is detected whether additional information newly received from a broadcasting station is different from previously received additional information. If the newly and previously received additional information are different from each other, it is also detected whether the newly received additional information is a substitute for the previously received additional information. If the newly received additional information is the substitute for the previously received additional information, previous redundant additional information stored in a memory is updated to the newly received additional information. Then, a visual indication of the updated additional information is provided to a viewer. When a scheduled program has been changed, such a situation is automatically detected and notified to the viewer. Therefore, the viewer can be prevented from becoming confused and also reserving an undesired program. In particular, information on a program after change is displayed in the form of a graphic symbol such as an icon, so that the viewer can visually readily recognize the program change situation without viewing detailed information.
