Delay-Aware Loss-Concealment Strategies for Real-Time Video Conferencing

One-way audiovisual quality and mouth-to-ear delay (MED) are two important quality metrics in the design of real-time video-conferencing systems, and their trade-offs have significant impact on the user-perceived quality. In this paper, we address one aspect of this larger problem by developing efficient loss-concealment schemes that optimize the one-way quality under given MED and network conditions. Our experimental results show that our approach can attain significant improvements over the LARDo reference scheme that does not consider MED in its optimization.
