<p>Apparatuses and methods for adjusting a quantization parameter to improve subjective quality are described herein. An example apparatus may include an encoder that may be configured to receive a macroblock and calculate a ratio between a level of activity of the macroblock and a variance of the macroblock. The encoder may further be configured to selectively adjust a quantization parameter associated with the macroblock based, at least in part, on the ratio.</p> |
