Abstract

Delivering high-fidelity audio over wireless channels is a challenging task because the wireless channel presents not only erasure errors, but also random bit errors. These errors have severe adverse effect on decompressing the received audio bitstream and may crash the decoder completely if not handled properly. To solve this problem, this paper addresses error resilient scalable audio coding (ERSAC) for wireless audio. Specifically, we perform data partition and reversible variable length coding, in the scalable audio bitstream. Simulation results show that ERSAC has very effective error-resilience in addition to bitstream scalability
