Abstract
A high quality TV transmission system is devised including a preprocessing circuit controlled by motion present in the scene to be transmitted. In the absence of motion, processing circuit derives output picture field signals of a standard frequency from a single input picture field scanned at a higher frequency. In the presence of motion, all input picture fields scanned with high number of lines are stored in storing devices and processed by interpolating low pass filters and a multiplexer into output picture fields having the standard frequency but being free of aliansing interference.
