ABSTRACT:
An encoding system of a simulcast high definition television and a method thereof capable of encoding an image signal of high picture quality and an aural signal of high tone quality. In order to improve a MIT proposal system, the bandwidth of a baseband image signal of a high definition television is compressed by a three-dimensional sub-band coding, divided sub-blocks are adaptively selected and modulated. Thereafter, the adaptive modulated signal is scrambled, transmission-gamma-processed, data-under-processed and processed by a double side band-quadrature modulation (DSB-QM). Thus, good picture quality in comparison with the MIT proposal system is obtainable.
