Abstract
This invention relates to a non-intrusive video quality assessment system. A method and apparatus are provided in which video frame parameters are extracted from a sequence of packets by generating a first video quality parameter for each group of packets associated with a particular frame of video data in dependence upon the frame rate of the video stream; and generating a second video quality parameter for each of said group of packets in dependence upon the size of encoded data comprising the video frame.
