Zusammenfassung: | PURPOSE:To invert the switching order of video memories correctly and smoothly without any disorder on a reproducing screen so that the screen returns to the past by providing at least three video memories and inhibiting the video memories from being switched in a reproducing section of a specific number of frames when the running direction of a recording medium is inverted. CONSTITUTION:A reproducing input signal Vin is inputted to a video signal memory 16. A readout address counter 21 starts counting up at a loaded address with an address loading signal S5 supplied from the address control circuit 19 of a memory switching control circuit 18, and consequently a field memory to be read is specified among the 1st-the 3rd field memories 13-15. Reproduced data are stored in two field memories in slow reproducing mode and the remaining one memory is used to read data; and the memories are inhibited from being switched specified times according to the reproducing state of a recording track by a head. |
