PURPOSE:To unitedly form a MUSE decoder and a MUSE-NTSC converter as a compact constitution and to obtain an NTSC signal of high picture quality. CONSTITUTION:A band-compressed MUSE signal is demodulated by decoding processing circuits 4, 5 and Y, B-Y and R-Y signals are obtained. These signals are outputted as HDTV signals through a matrix circuit 6 and D/A converter 7. On the other hand, the Y, B-Y and R-Y signals are converted at their sampling frequency by a sampling frequency converter 18. The frequency-converted signals are outputted as an NTSC signal through a scanning line converter 15, a D/A converter 16 and an NTSC encoder 17.
