Abstract: The Spectrum Compatible HDTV (SC-HDTV) system achieves the encoding of a 28.9 MHz source signal for transmission over a conventional 6 MHz channel. The new signal format reduces mutual interference between existing NTSC broadcasts and the new high-definition broadcasts to such a degree that significant amounts of currently “taboo”-ed spectrum space become available. As a result, every existing NTSC station can be assigned a second 6 MHz high definition channel. The HD encoding drastically reduces the required transmitter power which reduces the interference into NTSC broadcasts while at the same time providing immunity against interference by NTSC signals.
