Abstract
In a widescreen signal encoding system for a television-type signal, side panel chrominance information is conveyed in double sideband form on an auxiliary subcarrier having a field inverting phase relative to the phase of a standard chrominance subcarrier. Side panel high frequency luminance information exclusive of low frequency information also is conveyed on the auxiliary subcarrier, but in single sideband form. Illustratively the auxiliary subcarrier is at the 3.58 MHz frequency of the standard chrominance subcarrier.
