Multiple Description (MD) coding is a recently proposed solution for transmission of multimedia information over error prone data networks. In this paper, we consider the use of oversampled filterbanks to generate Multiple Descriptions for video coding. We consider the problem of filterbank design, error amplification, and efficient reconstruction in the presence of losses. A set of experiments...

Historically, multiple description coding (MDC) and post-processing error concealment (ECN) algorithms for video have evolved separately. Although 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 c...

We compare two strategies for lossy source description across a pair of unreliable channels. In the first strategy, we use a broadcast channel code to achieve a different rate for each possible channel realization, and then use a multiresolution source code to describe the source at the resulting rates. In the second strategy, we use a channel coding strategy for two independent channels couple...
