FEC-based packet loss recovery for AVS-M audio codec
Jianli Liu, Shenghui Zhao, Jing Wang, Jingming Kuang · 2011
In this paper, we utilize sender-based Forward Error Correction (FEC) techniques to enhance the robustness of packet loss recovery for AVS Mobile speech and audio (AVS-M) codec. Two FEC schemes are proposed which take the advantage of the codec's structure characteristics and do not introduce extra delay. The objective and subjective listening tests results show that the two methods achieve higher reconstructed quality than the codec's original frame erasure scheme in the case of packet loss.
