Abstract
A coding technique for high-definition television signals involves splitting the luminance signal into four sub-bands using a sub-band encoder and separately encoding each sub-band using a simplified vector quantization technique. The characteristics of each respective simplified vector quantization encoder can be matched to the characteristics of the respective sub-bands.
