Abstract
A two-stage multiple description predictive coding technique is proposed. A predictive encoder is used in the first stage of each description. The two encoders are designed to create staggered quantizers for the input, which allow further refinement of the joint reconstruction in the second stage. Theoretical analysis and simulation results show that this method is very efficient in the high rate multiple description coding of strongly correlated sources.
