摘要
多媒体实时应用是未来 Internet上的重要业务之一 .针对 IP电话和多点音频会议 ,本文提出了一种基于单播和组播的、混合通信方式语音实时通信系统的实现方法 ,着重介绍了系统结构的设计、语音编码、传输、通信及相关控制技术 .多次实验表明 ,系统在 Intranet上运行情况良好 .
Application real time multimedia is one of the most important services on the internet.This paper proposes an implementing scheme of audio communication system based on multicast,together with unicast for audio conference and IP phone respectively.The design of the system structure,the audio code,the transmission of audio data,the communication modes as well as the control techniques associated with the system are introduced in detail.Numbers of experiments indicate that the system running on the intranet is always in good condition.
