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 trafc) the VN-Matrix 300

carefully manages the data stream to minimize any image disruption.
