ABSTRACT:
In a video recording system the chroma components of a color television signal are applied to a multiplexer where they are interleaved in frequency with each other so that the energy concentration of each chroma component occurs at frequencies interleaved with the frequencies at which the energy concentration of the other chroma component occurs. The interleaved chroma components and the luminance component are supplied respectively to frequency modulators each producing an output having energies distributed over the full range of the passband of the system. The outputs of the modulators are fed to first and second transducers for recording the luminance and chroma components on adjacent tracks of a recording medium.
