Abstract:
A method for transmitting data using multiple description vector quantization, the method comprising:(a) quantizing a source vector at a lattice vector quantizer; (b) applying a labeling function to the source vector quantized in (a), the labeling function creating at least a first data stream and a second data stream such that the first data stream includes a first representation of the source vector, and the second data stream includes a second representation of the source vector, the first representation and second representation having equivalent reproduction quality, wherein said applying a labeling function includes associating the quantized source vector with at least a first sublattice point that is itself associated with a first data code word, and a second sublattice point that is itself associated with a second data code word; and (c) encoding both the first data stream and the second data stream.
