摘要：

This paper presents a coding scheme suitable for transmission of multimedia data over mixed internet and wireless channels. To resist packet losses and provide good compression performance, an entropy-constrained multiple description trellis-coded quantizer is combined with a variable-length code. Furthermore, to be robust to transmission errors, an iterative decoding scheme is developed, which exploits the redundancy between the generated descriptions. Experimental results show the performance of this scheme in terms of efficiency and robustness.
