ABSTRACT:
An input video signal is converted into a digital signal by a clock of a predetermined time interval. Of the time base errors included in the above signal, time base errors of the clock unit are corrected by resetting the write address of the memory, and time base errors of less than the clock unit and velocity errors are corrected by an interpolation filter provided at a later stage of the memory. By the above processing, it is possible to correct time base errors by only a clock of a predetermined interval and it is also possible to improve interface characteristics with other digital processing sections.
