Successive picture fields in normal operation are successively written into a one-field memory and displayed by nondestructive read-out. A stop order stops the tape while the last recorded picture field is continuously displayed and backs up the tape to a point from which it can be restarted to store either the next preceding or the next following picture field, according to the next order entered into the equipment. An address memory is supplied with addresses read off the tape by a counter roller and a timing mark reading head. A stop order interrupts the advancing of the address in storage by the tape advance reading head, causing the tape to be stopped and backed up at the end of memorizing the picture field being reproduced. A forward step or backward step order increments or decrements the address memory and restarts the tape, and when the addressed picture field is reproduced, it is stored in the memory, after which the usual stop and back-up automatically takes place. An order for resumption of progressive television picture reproduction can also be supplied to the system.
