Estimation of the Visual Quality of Video Streaming Under Desynchronization Conditions
Journal Title: International Journal of Advanced Computer Science & Applications - Year 2011, Vol 2, Issue 12
Abstract
This paper presents a method for assessing desynchronized video with the aid of a software package specially developed for this purpose. A unique methodology of substituting values for lost frames was developed. It is shown that in the event of non-similarity of the sent and received sequences because of the loss of some frames in transit, the estimation of the quality indicator via traditional (existing) software is done inaccurately. We present in this paper a novel method of estimating the quality of desynchronized video streams. The developed software application is able to carry out the estimation of the quality of video sequences even when parts of the frame is missing, by means of searching out contextually similar frames and “gluing” them in lieu of the lost frames. Comparing obtained results with those from existing software validates their accuracy. The difference in results and methods of estimating video sequences of different subject groups is also discussed. The paper concludes with adequate recommendations on the best methodology to adopt for specific estimation scenarios.
