ABSTRACT:
A luminance signal is frequency modulated with an FM carrier to generate a frequency modulated signal having a frequency spectrum within a frequency band of 1.6 to 8 megahertz. A second signal such as a line sequential color signal is single sideband modulated with a second carrier to generate a second modulated signal having a frequency spectrum in the form of a single sideband to one side of the second carrier that is located in a frequency band outside of the frequency band of the frequency modulated signal in a region that is generally empty of frequencies belonging to the frequency modulated signal. The single sideband may be the lower sideband between 0-1.2 megahertz. The two modulated signals are then recorded on a magnetic tape.
