摘要:
An apparatus and method for enhanced bit rate reduction of color video signals which provide for converting each selected picture element of the color video signal into its characterizing luminance and wavelength parameters through a series of transformations, and transmitting only the luminance and wavelength parameters over the transmission channel. Inverse transformations are utilized to reconstruct the color video signal on the receive side of the transmission channel. The apparatus and method make it possible to reduce the bit rate, power and/or bandwidth requirements for or increase the quality of color video signal transmissions.
