ABSTRACT:
Apparatus for correcting time base error (such as flutter, scatter, and skew) in a multichannel, sampled-analog type video signal includes means for clocking the signal portions carried by respective channels into respective deflutter buffers by respective input clock signals derived from horizontal sync information appearing in respective channels. Each buffer contains input register means capable of receiving a signal portion containing flutter distortion, storage means for holding the signal portion received, and output register means for delivering the signal at a substantially constant periodic rate. The input register means is controlled by the input clock signal, which contains flutter distortion corresponding to the flutter distortion in the signal portion. By synchronously delivering the signal portions from the output register means in all of the buffers, under control of a common output clock signal, flutter is removed from the signal portion in each channel, and inherently, scatter and skew among the signal portions in respective channels are removed from the signal.
