1. An apparatus comprising:

  • an encoder circuit configured to generate a plurality of coefficient values in response to a video stream and a number of quantized values;

    a quantizer circuit configured to generate said number of quantized values in response to said coefficient values, two or more quantization dead zones and two or more offsets; and

    a control circuit configured to set said two or more quantization dead zones and said two or more offsets to different values, wherein said two or more quantization dead zones and said two or more offsets are independently programmable.
