Data compression for high definition TV - An NTSC compatible approach
Abstract
A new approach is given for efficient digital encoding of HDTV by using a second 'auxiliary' channel to transmit detailed differences from a digitally encoded NTSC channel. This compatibility allows use of a less expensive receiver for decoding DBS NTSC signals for use with a standard television set. The decoder for HDTV is a separate add-on which utilizes almost all of the NTSC decoder.
