PURPOSE:To form a slow or a still reproducing screen from a reproducing data obtained at each track, even if data of plural memory areas is selected and read out in the order of field number and reproduced over the plural tracks. CONSTITUTION:Since the period of a control (CTL) pulse is twice that of the standard reproduction, in the 1/2 slow reproduction, a control counter 7 is incremented by one with twice track scannings, and a data selector 5 is switched with its count output. Thus, every time the storage to an one-field memory is finished at the double track scanning, the readout of memories 3a, 3b-3n is sequentially switched, resulting that the slow reproduction screen of 1/2 speed is obtained. Since the data of the same track having the same field number is stored in each memory, even if the reproduction scanning is done over two tracks, the reproducing screen is not disturbed. In case of the 1/2 slow reproduction, the content of each one-field memory is read out twice. |
