ABSTRACT:
A picture display apparatus adapted to pictures having an aspect ratio 16/9, permitting the simultaneous control of the line length and the vertical spacing of the lines. For the reception of pictures having an aspect ratio 4/3, the two control circuits are coupled in such a manner that the length of the lines of the displayed picture is decreased (2, 20) when the vertical spacing of the lines is normal or that the length of the lines of the displayed picture is normal when the vertical spacing between the lines is increased (3, 6). In addition, the control circuits are a continuously variable type, and access of the user to the control circuits is effected by remote control.
