Patent ID: 8279947

Claim:
A multiple-description decoding method, comprising: receiving, by a hardware decoder, multiple-description bit streams, and decoding, by the hardware decoder, the multiple-description bit streams to generate a second description signal; processing, by the hardware decoder, the second description signal through a second multiple-description inverse transformation method to generate a first description signal; and processing, by the hardware decoder, the first description signal through a first multiple-description inverse transformation method to generate a reconstruction signal; wherein the first multiple-description inverse transformation method includes a multiple-description parity synthesis or a multiple-description inverse dual transformation, and the second multiple-description inverse transformation method includes a multiple-description inverse scalar quantization; or wherein the first multiple-description inverse transformation method includes a multiple-description inverse scalar quantization, and the second multiple-description inverse transformation method includes a multiple-description parity synthesis or a multiple-description inverse dual transformation.
