Abstract

PURPOSE: To realize simple and inexpensive constitution by reproducing a picture signal simultaneously with an audio signal by using a two-level digital signal decomposed into picture elements, and then by displaying a dot picture on a magnetic picture display plate.
CONSTITUTION: An audio signal recorded magnetically on audio signal recording track T0 on magnetic tape 1 is reproduced by magnetic head H0' and audio signal reproducing circuit 9, composed of an amplifier, etc., and output from loudspeaker 10. A picture signal recorded on picture signal recording track Tv on magnetic tape 1, on the other hand, is read out by multiheat 11 for a digital signal read composed of magnetic heads H1'WH7' and picture signal read circuit 12 and changed into a pulse waveform and a two-level digital picture signal is reproduced via inverting waveform shaping circuit 14. Then, this reproduced picture signal is supplied to multistylus magnetic heat 15, scanning on magnetic picture display plate 16, to drive the head so that a dot picture will be displayed on picture display plate 16. Thus, the constitution is simplified and low priced.
