Description: iLBC 产生背景
在VoIP的应用中,大部分厂商采用CELP (Code Excited Linear Prediction) 算法的低速率语音编解码,如ITU G.729和G.723.1等。而VoIP应用主要在包交换的IP网络上进行传输,无法避免IP网络的丢包、延时、抖动等实时传输问题,而传统的这几个CELP算法对高丢包的处理不是很好,因而很大程度上会影响语音通话效果。
-iLBC background in the application of VoIP, Most manufacturers to use CELP (Code Excited Linear Prediction) Algorithm low-rate voice codecs, such as G.729 and ITU G.723.1, etc.. And the main application of VoIP in the IP packet-switched network for transmission, could not avoid IP network packet loss, delay, jitter and other real-time transmission, and a few traditional CELP algorithm to handle the high packet loss is not very good, which will largely affect voice calls effect.
