Video encoding in the spectrum-compatible HDTV system
Wayne E. Bretl, Richard Citta, Pieter Fockens, R. Lee · IEEE Transactions on Consumer Electronics · 1990
Video compression is achieved in the spectrum-compatible high-definition television (SC-HDTV) system by adaptive transform subband coding. The number of subbands is significantly increased, and the temporal processing is greatly reduced. Coefficients are transmitted as analog data; side information representing adaptation is transmitted as part of the digital data signal.>
