摘要：
Due to its limited bandwidth, lossy compressed video is very important in wireless video transmissions. In this paper, we proposed a quality, evaluation framework bused-on motion activity information, and two concepts, video definition and video smoothness are introduced into digital video metrics. Motion activity, description method is essential to both aspects. Two simple but effective methods describing motion activities are presented first. Then, the role of motion activity played in the quality evaluation of video definition and video smoothness is set forth. The framework is fit for applications in a wide range.
