RTP Timestamp:与NTP时间戳对应,与RTP数据包中的RTP时间戳具有相同的单位和随机初始值。 Sender’s packet count:从开始发送包到产生这个SR包这段时间里,发送者发送的RTP数据包的总数. SSRC改变时,这个域清零。 Sender`s octet count:从开始发送包到产生这个SR包这段时间里,发送者发送的净荷数据的总字节数(不...
This document describes a header compression scheme for point to point links with packet loss and long delays. It is based on Compressed Real-time Transport Protocol (CRTP), the IP/UDP/RTP header compression described in RFC 2508. CRTP does not perform well on such ...
RTP Control Protocol (RTCP) is used in conjunction with RTP to send information back to the sender about the media stream. RTCP is primarily used for the client to send quality of service (QoS) data, such as jitter, packet loss and round-trip time (RTT). The server may use this inform...
丢包(Packet loss)是指一个或多个数据数据包(packet)的数据无法透过网上到达目的地的情况,无论是Windows还是Linux系统中都会出现丢包的情况。netem是Linux2.6 及以上内核版本提供的一个网络模拟功能模块。该功能模块可以用来在性能良好的局域网中,模拟出复杂的互联网在Linux系统中性能,诸如低带宽、传输延迟、丢包等等情况...

Picture Loss Indication (PLI) 和 Full Intra Request (FIR) 虽然不是标准的RTCP报文类型,但PLI和FIR是通过RTCP APP报文实现的两种常用的视频流控制机制。PLI用于请求发送方重新发送关键帧(I帧),通常在检测到视频失序或严重错误时发送。FIR则更具体地要求接收方发送一个完整的I帧刷新,以恢复解码器状态或改善视频质量...
This means (especially in cases with high packet loss probability in which picture header contents are not expected to be highly predictable) that the sender may find it advisable always to set the subfield UFEP in PLUSPTYPE to '001' in the H.263+ video bitstream. (See [H263] for the ...
The method of the present invention can effectively reduce the network overhead, reducing the packet loss is high due to frequent data transmission, can greatly improve the service quality streaming service.CNdoi:CN101814973 A欧志CN101814973A * Jan 29, 2010 Aug 25, 2010 深圳市融创天下科技发展...

This interval can be used to keep regular receiver reporting down to a minimum, while still allowing receivers to send early RTCP packets during periods requiring more frequent feedback, e.g., times of higher packet loss rate. Note that although RTCP packets may be suppressed because they do ...
