Abstract: This article describes the bit-rate reduction of high-definition television (HDTV) signals. A fiber-optic HDTV 400-Mbit/sec digital transmission system has been developed with the use of time compression multiplexing (TCM), Nyquist sampling, and linear pulse code modulation (PCM) coding technologies. The target of this study is a bit-rate reduction to one-fourth the original data rate for HDTV signals. This system is applied to both an analog transmission and a digital transmission, with a bit rate of approximately 100 Mbits/sec. The simulation of HDTV bit-rate reduction shows that a combination of TCM, subsampling, and intraframe digital pulse code modulation (DPCM) technologies efficiently reduces HDTV transmission bit-rate to less than one-fourth.
