摘要
对LRMP中的局部错误恢复技术进行了研究,为适应实时音频传输的需要提出了改进方法。通过对层次划分原则的改进可缩短恢复时间。对执行恢复条件的判断可保证接收方在遭遇严重的连续丢包时也能恢复。
After analyzing the characteristic of LRMP's local error recovery technology, the paper proposes an improved method
for the need of real time audio's transfer. The method can shorten recovery time by the improving division principle of
subgroup's hierarchy. And when the receiver meets badly continuously drop data packets, the method can ensure it to
resume those lost packets by the judgment of recovery condition.
