UNBALANCED MULTIPLE DESCRIPTION VIDEO COMMUNICATION
USING PATH DIVERSITY

ABSTRACT
Multiple description (MD) coders provide important error resilience
properties. Specifically, MD coders are designed to provide good
performance when the loss is limited to a single description, but it
is not known in advance which description. In [1], we combined
MD video coding with a path diversity transmission system for
packet networks such as the Internet, where different descriptions
are explicitly transmitted through different network paths, to im-
prove the effectiveness of MD coding over a packet network by
increasing the likelihood that the loss probabilities for each de-
scription are independent. The available bandwidth in each path
may be similar or different, resulting in the requirement of bal-
anced or unbalanced operation, where the bit rate of each descrip-
tion may differ based on the available bandwidth along its path.
