ABSTRACT
Historically, multiple description coding (MDC) and post-
processing error concealment (ECN) algorithms for error-
resilient video transmission have evolved separately. Al-
though multiple description coding provides a way to make
the video quality degrade gracefully in the presence of packet
losses, the resulting quality may be unsatisfactory when only
one description is used to reconstruct the signal. This paper
proposes a joint description transform coding (MDTC) and
statistical error concealment algorithm that adopts a maxi-
mum a posteriori (MAP) estimation approach to compen-
sate for the loss of descriptions. This coordination results
