It calculates network parameters such as delay and loss rate based on RTCP,and then maps them to different speech quality scores.
分析了影响因特网语音通信质量的主要因素,根据实时传输控制协议计算延迟、丢包率等网络参数,并利用RBF神经网络将参数映射为语音质量评分,根据评分值的变化动态地调整语音终端的编码速率,在保证一定语音质量的同时,缓解网络拥塞。
Based on the analysis of the features and performance of web camera, the paper points out that RTP and RTCP protocol are more suitable for video transmission though the internet than TCP protocol, and that embedded platform is the right choice for web camera because of its portability and lower price.
基于对网络摄像机这种特定应用的需求分析,指出了视频信号网络传输的特点在于实时性要求高,而可靠性要求相对较低,因此RTP(实时传输协议)和RTCP(实时传输控制协议)协议比TCP协议更适合应用于网络视频传输。
In this project,the protocol of UDP and RTP/RTCP was used.
运用用户数据报协议 (UDP) ,实时传输控制协议 (RTP/RTCP)和H 。
