The temporal and spatial redundancies of image sequences can be reduced by prediction and vector quantization, respectively. The robustness of the coder is increased through the use of a hybrid two-stage vector quantizer. The first stage is of the Linde-Buzo-Gray type. The second stage encodes the residual error of the first stage using a lattice vector quantizer.
