    摘要: A macro-block (MB) quantization reactivity compensation method for a video encoder is provided. The method calculates a reference picture quantization value based on a calculated picture complexity. This predicted reference quantization is combined with the bits-used reactive MB reference quantization value to determine the final MB reference quantization value. This MB reference quantization value is also made adaptive to the VBV buffer fullness, as well as to the predicted change of the current picture complexity. A video encoder and an article of manufacture that comprises computer readable program code for execution of the method are also provided.
