An efficient packet loss recovery technique for voice over Internet

This paper presents an efficient packet loss recovery technique for voice over Internet based on parity-based piggy-backed forward error correction technique (PPFEC), which can recover most of the lossy packets during the lossy network. Combining the PPFEC technique with error concealment techniques of speech coding, we also develop an important-information protection based FEC to get a better tradeoff between decoding quality and bandwidth. Experiments show that our approach performs well under various packet loss conditions.
