  • Patent number: 9641901
    Abstract: A method for displaying an electronic program guide (EPG), which includes one or more pages divided into a plurality of program name display regions, provides a list of names of currently-broadcast programs through each of the program name display regions such that a user may search all currently-broadcast programs. TV viewers may determine information on currently-broadcast programs through an effective display method with classification criteria, and quickly change a page screen through movement between columns. TV viewers may select a desired broadcasting program from the channels through a minimum key manipulation of a remote control. Program names are classified according to the classification criteria such as genres, recently watched channels, and favorite channels in the EPG. The classification criteria may be set by each user, or a separate item may be added, so that a user may easily acquire broadcasting program information.
