Abstract
A bit string of a video encoded using motion-compensated inter-frame prediction and DCT and, more particularly, H.264 is received. A quantization parameter included in the received bit string is extracted, and its statistic is calculated. The subjective quality of the video is estimated based on the minimum value of the quantization parameter.
