ABSTRACT:
A time base corrector (TBC) for a special-motion video reproduction system employing a helical-scan VTR generates write-in address data synchronized to the reproduced digital data and stores the digital data in a digital memory in accordance with the generated write-in address. When the reproducing head jumps vertically, i.e. perpendicular to the data track, the currently-generated write-in address is latched. In response to a reference signal, the latched data is transferred to a read-out address counter for generating a read-out line address, and the stored video signal is then read out of the digital memory under control of the read-out address data.
