ABSTRACT:
For transmitting digital HDTV signals, the HDTV signal, which is either fed with a data rate of .ltoreq.20.48 Mbit/s or which is data-reduced to such a data rate of .ltoreq.20.48 Mbit/s by means of a method utilizing the psycho-optical phenomena of the human eye, is split at the transmitter side of a broadband transmission link operating on the DSR method into two data streams of .ltoreq.10.24 Mbit/s each, and is fed to the I/Q interface of the 4PSK modulator of the DSR transmission link. These two data streams whch are transmitted to the I/Q output of the 4PSK demodulator of the DSR transmission link are then further processed thereat.
