ABSTRACT:
As is well known, a virtually flicker-free picture is obtained by using a sufficiently high picture-reproducing frequency and doing without interlaced scanning. This is achieved with a suitable standard converter in which the picture is temporarily stored in digital form. By suitable multiplexing, the digital frame store (221, 222, 223) can also be used for the conversion of the text and graphics page. Multiplexer (26) and demultiplexer (27) are switched by a blanking signal (Blank, Blank') which is buffered in the frame store together with the associated picture section.
