ABSTRACT:
A circuit for correcting a fluttering video signal to conform to a standard time base utilizes a set of analog shift registers that are specially adapted to permit controlled parallel transfer of video line-scan information between registers. Such provision for parallel transfers permits exclusive assignment of input and output functions (and corresponding clocking) to respective registers. In a presently preferred implementation, three charge-transfer-type registers are aligned side by side on a single "chip" and control of parallel charge transfers between each cooperating pair of adjacent registers is achieved through the use of an interposed electrode structure.
