Abstract
The DPCM (differential pulse code modulation) for color television signal transmission has been improved both in picture quality and information compression, by a vector signal quantization called embedding quantization. According to the present invention, vector signal comprising a plurality of elements is quantized while the quantized output signal is obtained after a plurality of quantization and prediction operations. Number of repetition times of the quantization and prediction is for instance equal to the number of elements composing vector signal. A vector is for instance composed of three elements relating to red, green, and blue primary signals of a color television signal.
