Abstract--
Layered (LC) and multiple description coding (MDC)
have been proposed as source coding techniques that are
robust to channel errors for video transmission. In this
paper, we investigate and study the error-resilience capa-
bilities of these two encoding techniques through extensive
experimentation, and explore the environments where they
perform best. Although some of our conclusions agree with
those in the literature, we believe that this paper provides
the most comprehensive performance comparison yet be-
tween LC and MDC.
