A display apparatus comprises a signal converter (SC) which converts input
text information (IT) and interlaced input video information (IV) with a
number of video lines (Li) in a video field (Fi) into a display signal
(DS) which comprises display text (Ti) and display video (Vi). An
addressing circuit (AD) addresses a display screen (DSC) of the display
apparatus in successive non-interlaced display fields (Fi) which have a
duration substantially equal to the video field (Fi) and a number of
display lines (DLi) which is substantially twice the number of video
lines (Li). The signal converter (SC) has an output to supply the display
signal (DS) in which the display video (Vi) is present on odd or even
display lines (DLi) only, in respective successive display fields (Fi),
and in which the display text (Ti) is present on same display lines (DLi)
of the successive display fields (Fi).
