1. An apparatus, comprising:
- an encoder configured to receive a video signal and to generate a saliency score for a macroblock of the video signal, the encoder further configured to adjust a quantization parameter for the macroblock of the video signal based, at least in part, on the respective saliency score for the macroblock of the video signal.

Abstract
Examples of methods and apparatuses for improving subjective video quality of a video signal are described herein. An example apparatus may include an encoder. The encoder may be configured to receive a video signal and to generate a saliency score for a macroblock of the video signal. The encoder may further be configured to adjust a quantization parameter for the macroblock of the video signal based, at least in part, on the respective saliency score for the macroblock of the video signal.
