Unicast RTP — An Overview
Similar to multicast RTP, this method uses a real-time variation of UDP protocol, called
unicast RTP. This method can be used where the network infrastructure does not support
multicast traffic. Typically, this protocol is used for point-to-point configuration (single source
to single display), but can be configured to use up to a maximum of four displays.
NOTE: The encoder sends an individual stream to each decoder. This means that the
total bandwidth of the VN-Matrix system increases as more decoders are added.

RTP provides very low latency which is important for video streaming. Unlike other
protocols, RTP packets include a time stamp. If packets are received in the wrong
order, they are sorted into the correct order for display or discarded if the time stamp is
out-of-date.
However, because RTP is a connectionless protocol, data delivery is not guaranteed.
When data packets are lost (for example, due to excessive network traffic), the
VN-Matrix 200 / 225 / 300 / 325 devices carefully manage the data stream to minimize any
image disruption.
