Multiple description coding (MDC) is a technique used to obtain two or more (often correlated) descriptions of a source, which are transmitted over different channels to the receiver. These descriptions of the source support two levels of reconstruction quality. When all the descriptions are received and used in the reconstruction, the source can be reconstructed with high fidelity. When only a subset of the descriptions is received, the quality of reconstruction should still be acceptable. In this work, we introduce MDC (with two descriptions) in the context of classification based subband coding. We develop an efficient MDC scheme using multiple description scalar quantizers and present a greedy algorithm to allocate rates and redundancies among the classified subbands
