Abstract
A system and/or method for detecting white noise in a sequence of video frames, and a computer program product is described to affect the quantization step size. In the method/system the correlation between motion vectors of macroblocks is calculated and compared to a predefined threshold. The correlation between motion vectors is used as an indicator for noise in the frames. The quantization step size is then adapted according to the detected level of noise.
