Abstract
Methods and apparatuses for displaying broadcast history information of a plurality of episodes of a program on an audio-visual system, which enable a viewer to select a program for which the history information of each episode will be stored. In response to the viewer's selection, the audio-visual system stores the history information for the episodes of the selected program that has been received by the audio-visual system. The audio-visual system can display the history information when the viewer watches the current episode of the program in a future time.
