A no-reference measure for the effect of packet loss in video streaming over IP

This paper presents a no-reference measure for monitoring the effect of packet loss for streaming video over IP networks. The measure exploits the structure of the artifacts resulting from packet loss to estimate their effect on video quality while maintaining low computational complexity. This work is motivated in part by the fact that in streaming video over IP, a major degradation of quality occurs because of packet loss. It has a severe effect on video quality of compressed video because the temporal dependence in coding of video causes errors to propagate over several frames. In addition, unlike data transfer over IP, video quality is measured and perceived live at the end user terminal. Such a measure can thus be very useful in monitoring video quality delivered over IP and for various applications in the context of video transmission such as video on-demand.
