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” spectrum space become available. As a result, practically all existing NTSC stations can be assigned a second 6-MHz high -definition channel. The high-definition (HD) encoding drastically reduces the required transmitter power which minimizes the interference into NTSC broadcasts while at the same time providing immunity against interference by NTSC signals.
