ABSTRACT:
In a television receiver having a wide aspect ratio display device (for example 16:9) which is arranged to receive and display a television transmission relating to a 4:3 aspect ratio picture, the receiver may be set to expand the 4:3 aspect ratio picture to cover the whole width of the display. Where this results in subtitles which are superimposed on the picture to be lost (since the expansion causes a portion of the bottom of the picture to be undisplayed) an arrangement (28) is provided to detect the presence of subtitles and shift them to a displayed portion of the display.
