in an encoder, a digital video image signal is analyzed to obtain pixel blocks, motion vectors are estimated, and errors in the block are calculated using the decoded picture signal to produce a decision intra / inter and intra - block - an inter pixel values of image blocks or compensated by the movement.the difference of pixel values on the basis of the result of the error block. the blocks of pixel values and pixel values of difference are respectively processed by a dct block of coefficients coded motion vectors in a coder for variable length huffman word.the groups of coefficients are quantified individually coded (using a threshold of quantification factors and group are quantified individually coded using a quantization matrix, controlled by the congestion of a buffer memory.in a decoder, the groups of coded coefficients which belong to blocks of pixels are du00e9quantifiu00e9s individually using a limit of quantification coding and coded each coefficient of each group is du00e9quantifiu00e9 individually by using the inverse of a matri the quantization coding, commissioned by the congestion of a buffer memory.the groups of coded coefficients and motion vectors are decoded in a decoder for variable length huffman word to produce blocks of decoded coefficients.the blocks of coefficients are respectively processed by a dct decoded pixel values and opposite difference of pixel values of pixels, where blocks and blocks within the image from pixel values of blocks and inter image compensated by the movement, the values of difference for the pixel is generated based on a signal decision inter / intra.evaluation of the motion vectors. the blocks of pixels are filtered to the limit where the adjacent block which does not have nearly the same vector.
