UDP is an alterna tive to the Transmission Control Protocol TCP The advantage of UDP is that it is not required to deliver all data and may drop network packets when there is for example network congestion This is suitable for live video as there is no point in re transmit ting old information that will not be displayed anyway Unicasting is communication between a single sender and a single receiver over a net work This means that the video stream goes independently to each user and each user gets their own stream A benefit of unicasting is that if one stream fails it only affects one user Multicast is bandwidth conserving technology that reduces bandwidth usage by simul taneously delivering a single stream of information to multiple network recipients This technology is used primarily on delimited networks intranets as each user needs an uninterrupted data flow and should not rely on network routers AXIS 231D 232D Video Streams How to stream MPEG 4 Deciding on the combination of protocols and methods to use depends on your viewing requirements and on the properties of your network RTP RTSP This method actually RTP over UDP and RTSP over TCP should be your first consideration for live video especially when it is important to always have an up to date video stream even if some images do get dropped This can be configured as multicast or unicast Multicasting provides the most efficient usage of bandwidth esp
