Spectrum Compatible High-Definition Television Transmission System
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.
