Abstract

Improved apparent picture quality in film-to-video transfer television systems operating in accordance with an odd ratio between film frame display rate and television scan field/frame rate and wherein the video scan line rate is multiplied by an integer for display at an output television display device is achieved by the steps of: a. transferring each film frame to a television signal of predetermined numbers of even and odd video fields at nominal line scan rate in accordance with a predetermined transfer scheme related to the odd ratio; b. putting the television signal through a transfer medium; c. receiving at a receiver the television signal from the transfer medium; d. selectively passing the received television signal through plural, series connected field period delays to provide an undelayed portion and plural delayed signal portions, the total number of such portions being related to the odd ratio; e. separately time compressing each portion of the received television signal in accordance with an inverse of the integer to provide an undelayed and plural delayed signal time compressed components; and, f. selecting at a multiplexer among the undelayed and the plural delayed components so as to derive line multipled even and odd output video fields which, when displayed on a display of the receiver, manifest spatially aligned images corresponding to the original film frames.
