  • Scalable Coding with Partial Eror Protection
    Publication number: 20110026581
    Abstract: An encoder for encoding an audio signal, wherein the encoder comprises: a first encoder configured to receive an first signal and generate a second signal dependent on the first signal; a second encoder configured to generate a third signal dependent on the second signal and the first signal; a signal processor configured to partition the third signal into at least two parts; and a multiplexer configured to receive the at least two parts of the third signal and the second signal and combine the said signals to output an encoded signal.
