In a video signal coder blocks of pixels are generated, scanned in a pseudo-random order and transformed blocks of coefficients which are stored in a buffer. The resulting blocks of coefficients are quantized individually by the use of a quantization level and the coefficients of each block are individually quantized by the use of a quantization matrix. The quantization level is determined by the fullness of the buffer.
