Abstract

An NTSC compatible, single broadcast channel, widescreen EDTV system encodes and decodes a television signal comprising four components: (1) a main, standard format NTSC signal (N) with low frequency side panel image information compressed into the overscan regions thereof; (2) time expanded high frequency side panel image information (X); (3) extended high frequency horizontal luminance image information (Z); and (4) vertical-temporal luminance image information (YTN). Components (2) (X) and (3) (Z) are intraframe averaged (64, 76) and quadrature modulate (80) an alternate subcarrier (ASC), e.g., at 3.108 MHz, to produce a modulated signal (M). The modulated signal is summed (40) with component (1) after intraframe averaging to produce an NTSC compatible 4.2 MHz baseband signal (NTSCF). This signal and component (4) quadrature modulate (57) an RF picture carrier to produce an NTSC compatible RF broadcast signal for transmission via a single broadcast channel.
