In addition, the spread of digital TV broadcasts a variety of programs that are dozens of times than the conventional analog TV, and if satellite digital TV is universally distributed, it is possible to watch programs around the world. This would allow viewers to sit and watch hundreds or thousands of programs in their homes. In order to find information about the program and TV guide while watching thousands of such programs, the program is searched through the EPG (Electronic Program Guide) on a limited screen. Of course, there is an advantage that the program information is easily available through the EPG, but when the viewer just wants to know what the next program is while watching TV, the EPG should be full. Or, you will see a pop-up menu to see the next program name. In this case, the OSD (On Screen Display) and information, which are not necessary to see only the next program name, may interfere with the current program. You also see information that you don't need. In addition, if hundreds of programs are pressed by pressing the remote control key to find the next program one by one, the user will have to spend a lot of time and effort to find the required program name. In order to solve this problem, Korean Patent Application No. 2003-0015118 proposed a digital TV receiver which shows the program name of the next program automatically on the screen according to the user's preference, while the user easily finds the next broadcast program. .
