We are studying a probability of 2 programs of EDTV2 transmission via 27MHz or 36MHz bandwidth transponder by "MUCCS45" (45Mbps multi-channel TV coding system) In order to realize the transmission, a new quantizer suitable to EDTV2 characteristics is designed with a theoretical optimization for a video signal and a supplemental signal. As a result, 1〜3.5[dB] in SNR can be gained in computer simulations.
