A design of error robust scalable coder based on MPEG-4/Audio

This paper proposes a combined design for an error robust and scalable audio coder based on TwinVQ (transform domain weighted interleave vector quantization) object type and EP (error protection) tools (sic) in MPEG-4/Audio. By combining the inherent error-robustness of TwinVQ, the un-equal error-protection scheme, and the hierarchical scalable coding structure, the distortion is (sic) to be very minor, even in high-error channel conditions at bit rates of 16-32 kbit/s. These structures (sic) a (sic) coding framework which can be used for various types of network/storage environment and applications.
