Abstract: The present invention relates to a method of enabling a menu of a high-density recording medium to be displayed on a digital television set. According to this method, a recording medium includes real-time data belonging to one or more titles and/or chapters, and menu data belonging to a plurality of menu pictures, each picture having data contents differentiating each included menu item distinctively from the other menu items. When transmitting data of a menu picture in which a selected menu item has been differentiated from others, an infra-coded picture and one or more predictive pictures belonging to data of the menu picture are transmitted sequentially and circularly to a connected digital television set. This repetitive transmission of same contents makes a menu be displayed in still picture on a digital television set.
