Abstract :
When video packets are lost in congested networks, one loss pattern creates a different visual impact than another. We conduct a subjective experiment with H.264 videos and conclude that isolated losses are better than bursty losses in terms of perceptual video quality. A network-implementable video quality model is developed for a router to drop packets so as to achieve good visual quality.
