Summary:We present a construction of multiple description trellis-coded
quantizers. We use the tensor product of trellises to build a trellis
which is applicable to multiple description coding. The problems of
index assignment and set partitioning for the resulting trellis are
considered. The Viterbi algorithm provides the best path for encoding
and the design procedure utilizes a generalized Lloyd algorithm. The
encoding process simultaneously generates all the transmitted sequences.
Furthermore, the complexity of the scheme is almost independent of the
rate. The quantizer provides remarkable performance with little encoding
complexity
