The paper improves the reliability of audio streams in a lossy channel. The mechanism groups
audio data samples into source and carrier sets. The carrier set carry the information about the
source set which is encoded using data hiding methodology - quantization index modulation. At the
receiver side, a missing source data sample can be reconstructed using the carrier set and the
remaining source set. Based on reliability constraints a hybrid design combining interleaving and
data hiding is presented. Experiments show an improved reliability as compared to forward error
correction and interleaving.
