Method of recording a video signal, in particular a colour video signal, on a record carrier, in which method a combined signal is produced which contains a carrier which is modulated in frequency by the luminance information, and a subcarrier which lies below the frequency band of this modulated carrier and is modulated, for example, by the colour information. The zero crossings of the ascending and descending edges of the modulated carrier are shifted in opposite dependence upon the modulated subcarrier and recorded on the record carrier as information-containing quantities. |
