Trellis-coded quantization (TCQ) is a powerful source coding scheme that was introduced in [I]. TCQ has been used in the design of several image coding systems due to its very good rate-distortion performance. In fact, TCQ has been shown [I] to provide greatly improved rate-distortion performance as compared to scalar quantization. It also provides significant robustness This material is based upon work supported by Motorola, Inc., and the National Science Foundation under Grant No. CCR- 9733897.

N2 - This paper presents the design of multiple description trellis-coded quantizers that are optimized for transmitting data over multiple noisy channels. A multiple description channel-optimized trellis-coded quantization (MDCOTCQ) scheme is developed whereby all trellis-coded quantizers (side and central) are designed to operate over the binary symmetric channel with a given bit error rate (BER). Using the tensor product of trellises, an expression of the multi-channel transition probability matrix is derived. This formulation enables the construction of multiple description channel-optimized trellis-coded quantizers for arbitrary bit rates and arbitrary channel bit error rates. The proposed MDCOTCQ system enables the transmission of compressed data over noisy diversity or packet-based communication systems, and enables outstanding robustness to channel or packet loss. Examples are presented to illustrate the performance of the proposed MDCOTCQ-based source coder.
