ABSTRACT:
A video signal sequence, corresponding to a chromatically double-sequential, nesting, interlace scan is used to obtain the simplest possible devices for the recording, transmission and/or storage of a color televison image. Two signals associated alternately line by line with different color separations, are used to this end. One of the signals also contains two signal components, which are associated in line portions with two different color separations. The video signal sequence is repeated line by line, half-frame by half-frame or frame by frame, prior to image reproduction and thus results in an image reproduction, from one and the same signal sequence, of good quality when using simple apparatus and of subjectively perfect quality when using more complex apparatus.
