Abstract

Apparatus for augmenting a television signal with auxiliary signal includes circuitry for modulating a picture carrier with baseband video signal to generate a vestigial sideband television signal. Auxiliary signal (54) is modulated on a further carrier (CA) of such frequency that the upper sidebands fp - (2n+1)fH/2 of the modulated further carrier, representing the auxiliary information, 1) occupy the frequency spectrum of the vestigial sideband of the vestigial sideband television signal (50) and 2) occur clustered at odd multiples of half line frequency. The sidebands of the modulated further carrier are added (52) to the vestigial sideband television signal in frequency interleaved fashion in the vestigial sideband spectral region.
