Abstract
The present invention relates to a method and system for controlling the quality of video data by selecting the optimal quantization parameter during encoding. The system is configured to perform quantization for one or more macroblocks using a different range of step sizes, then the kurtosis for the respective quantized data is performed to determine the macroblock and the corresponding quantization step size that yields the highest kurtosis value. The quantization step size that generates the highest kurtosis value is selected to the blocks of input-video data during encoding.
