Abstract :
A new variable-rate embedded quantization technique, called embedded entropy-constrained trellis coded quantization (E-ECTCQ) is developed. Its performance is compared to that of variable-rate embedded scalar quantizers. Simulations indicate that performance depends both upon the number of embedded quantization stages and the number of trellis states
