摘要：

We propose an efficient stereo audio coding scheme with error protection based on transformed vector quantization. This scheme includes a new stereo coding method, called adaptive inter-channel prediction stereo, that achieves high-efficiency stereo coding at a low coding bit rate. This scheme also includes an unequal error protection (UEP) method that achieves high-efficiency error protection against radio transmission error. We also report a real-time audio transfer system on the Japanese Personal Handyphone System (PHS) using the proposed coding scheme, which enables a high-quality audio transfer service over mobile channels.
