VN-Matrix 300 • Introduction 6
Unicast RTP
Like Multicast RTP, this method uses a real-time variation of UDP protocol, called RTP. This
method can be used where the network infrastructure does not support multicast traffic.
Typically this should be used as a point-to-point configuration (that is: single source to single
display) but it can also be used for up to four displays.

Figure 3. Using Unicast RTP Where the Network Infrastructure Does Not Support
Multicast Traffic
RTP provides very low latency which is important for video transport. The RTP protocol
compensates for jitter and any breaks in the sequence of data during the transfer over an IP
network.
However, because RTP is a connection-less protocol, data delivery is not guaranteed. Where
data packets are lost (for example: due to excessive network traffic) the VN-Matrix 300
carefully manages the data stream to minimize any image disruption.
