Abstract
In a television reproduction system in which recorded video for one field, either odd or even, is repeatedly scanned, such as for still or slow motion reproduction, and is displayed with a locally generated synchronizing signal which produces interlaced scanning having both odd and even fields on a television screen, video from adjacent lines is averaged when the recorded field being scanned is an odd or even field and the field defined by the synchronizing signal is the opposite type. When the recorded video is a color video signal, the luminance and chrominance components of the video signal are separately averaged, the chrominance component is inverted in dependence on the relationship between the phase of the color subcarrier of the recorded line being reproduced and the phase of the color subcarrier of the locally generated synchronizing signal.
