Abstract
A television system includes a plurality of complementary transmitter and receiver stages for processing an HDTV signal to minimize co-channel interference to and from NTSC signals, thereby facilitating the use of so-called "taboo" channels for the transmission of HDTV signals. The HDTV signals are encoded for transmission in a format exhibit dominant periodicities equivalent to that of NTSC to further minimize such co-channel interference.
