Abstract
A converter for television signals formed of a television signal converter, a selection position changer and a position display. The television signal converter converts a first television signal corresponding to a selected portion of a picture of a first television system to a second television signal of a second television system so that the selected portion of the picture of the first television system fills the entire screen of the second television system. The aspect ratios of the first and second television system are different. The selection position changer changes the position of the selected portion of the picture of the first television system. The position display displays information about the position of the selected portion of the picture of the first television system.
