FOERFARANDE FOER OEVERFOERING, SAERSKILT FOER REGISTRERING OCH AOTERGIVNING AV TV-SIGNALER.

摘要

Method for recording and reproducing color television signals in timeplex. In the signal to be recorded a carrier is additionnally coupled and used for synchronization, of which the frequency is symmetrically inverted as to the half line frequency with respect to a central frequency. The frequency and the amplitude of the additionnally coupled carrier are selected so as to adversly affect the luminance and color data.
