Audio quality in lossy networks for media‐specific forward error correction schemes
Atsushi Inoie · International Journal of Communication Systems · 2012
SUMMARY A media‐specific forward error correction (FEC) is used to prevent the loss of audio packets due to noise or interference in the transmission and buffer overflow in the router. In this FEC scheme, fornth packet, the redundant data are added in (n + ϕ)th packet whereϕis called the offset. In this paper, we consider an M/M/1/Kqueueing system and derive some simple expressions for calculating the audio qualities of the aforementioned schemes. We analytically and numerically show some counter‐examples and characteristics for these FEC schemes by using our analytical model. Copyright © 2012 John Wiley & Sons, Ltd.
