ABSTRACT:
Apparatus for a multi-screen display including a multiprocessor for processing signals from at least one signal source and for applying processed signals to a plurality of display units arranged in at least two rows so as to form the multi-screen display. The multiprocessor includes vertical scanning format transformation apparatus for transforming a vertical scanning frequency of the output signal of the multiprocessor to be a higher vertical scanning frequency than that of a vertical scanning frequency of the input signal of the multiprocessor so that a ratio of the vertical scanning frequency of the output signal applied to the multi-screen display to the vertical scanning frequency of the input signal is at least two, thereby substantially eliminating discontinuity distortion of a moving pole image displayed as a reproduced picture on the multi-screen display.
