在IP电话和远程会议系统等实时应用中
丢包不可避免并极大地影响传输服务质量.前向误差校正法FEC(Forward Error Correction)是实时修复丢包的一种较好的方法.本文介绍了FEC丢包修复方法的原理
并把丢包修复功能结合到我们实现的实时传输协议RTP(Real-time Transport Protocol)库中
验证了丢包修复功能的正确性.
In real-time applications
such as IP phones and remote conference systems
packet loss that impairs quality of transmitting severely is inevitable.FEC (Forward Error Correction) is a better way for repairing lost packets.In this paper
a method of lost repairing with FEC based on RTP(Real-time Transport Protocol) was designed and implemented. Then a testing method of lost repairing function and results are illustrated.
