Polyphase down-sampling multiple-description coding for IP transmission

Recently the problem of transmitting data over heterogeneous networks has received considerable attention. Our specific interest is the communication of still images. In this work we present a Multiple Description system based on Polyphase DownSampling algorithm (PDMD) that splits an image source in an arbitrary number of balanced descriptions. Our goal is to obtain both the best reconstruction quality from the received descriptions (also only one) and a subjective indistinguishable reconstruction from the original, if all the descriptions are available.
