A new form of trellis coded quantization is presented based on uniform quantization thresholds and "on-the-fly" codeword training. The universal trellis coded quantization (UTCQ) technique possesses several desirable features. Neither stored codebooks nor a codebook design algorithm are needed, yet UTCQ performance is comparable with fully optimized entropy-constrained trellis coded quantization (ECTCQ) for most rates. The UTCQ codebook and trellis geometry are symmetric with respect to trellis superset. For sources with a symmetric probability density, this allows use of a single variable-rate code in subsequent entropy coding. Uniform thresholds simplify the quantization process by eliminating binary tree searches. Performance o...
