ABSTRACT
Multiple description (MD) video coding can be used to reduce
the detrimental effects caused by transmission over lossy packet
networks. Each approach to MD coding consists of a tradeoff
between compression efficiency and error resilience. How
effectively each method achieves this tradeoff depends on the
network conditions as well as on the characteristics of the video
itself. This paper proposes an adaptive MD coding approach
which adjusts to these conditions through the use of adaptive
