The present application is directed to techniques and tools for adapting the quantizer as well as the quantization step size used during video encoding. For example, a video encoder uses a non-uniform quantizer (having a relatively large dead zone ratio) for B-picture types, but uses a uniform quantizer...http://www.google.es/patents/US20070237222?utm_source=gb-gplus-sharePatente US20070237222 - Adaptive B-picture quantization control
