ABSTRACT:
A system for recording a color television signal. The color information is recorded as an amplitude modulation. This color information consists of a first and a second color-difference signal, which two color-difference signals are transmitted in a line-sequentially alternating exhibiting a 90.degree. phase-shift during consecutive line periods. Third and fourth additional signals are quadrature-modulated with the first and second signals, respectively. Each of these additional signals comprises the difference between one of the color-difference signals during a selected line period and the value of the same signal during the preceding or next line period.
