A video image encoder estimates a quantization noise curve which will result from quantizing a coefficient data block and uses the estimated quantization noise curve and a specified minimum noise value to select the quantization step size actually used to quantize the coefficient data block. The quantization...http://www.google.es/patents/US5654760?utm_source=gb-gplus-sharePatente US5654760 - Selection of quantization step size in accordance with predicted quantization noise
