A high definition television encoder which provides an efficient use of bandwidth, segments line differential signals into left panel, center segment, and right panel line differential signals and time expands the left and right panel line differential, panel, and luminance signals. The time corresponding expanded left and right panel line differential signals are arranged in time coincidence and quadrature modulated, as are the corresponding segments of the panel signals. The quadrature modulations providing signals in contiguous frequency bands. Luminance signals are converted to a band abutting the contiguous frequency bands as are digital audio signals. The digital audio signals, quadrature modulated signals and luminance signals are frequency multiplexed within a 3 MHz band.
