Accurate video-quality estimation without video decoding

This paper proposes a video-quality estimation method which does not need video decoding. It takes into account error-concealment effectiveness and the location of video-quality degradation to estimate video-quality from only packet-header information. Error-concealment effectiveness is evaluated on the basis of motion-level information estimated by the data-size of each frame. The quality-degraded location in a frame is evaluated by the transmission-error timing. Experimental results show that a high correlation coefficient of 0.853 with a lower outlier ratio is achieved with the proposed method. The method is suitable for a low-complexity video-quality monitoring system in IPTV services due to its accurate video-quality estimation without video decoding.
