Unicast RTP — An Overview
Similar to multicast RTP, this method uses a real-time variation of UDP, called unicast RTP.
Unicast RTP is 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 stream 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.

Using RTP, encoder sends data
to up to 4 specified decoders.

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out-of-date.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 devices carefully manage the data stream to minimize image disruption.
Unicast TCP — An Overview
This method transports data using standard Transport Control Protocol (TCP) and should
only be used for single point-to-point transfer of data.
TCP is a connection-based protocol and, therefore, data delivery is guaranteed. However,
in the event of excessive network traffic, delivery can be delayed, impacting real-time
performance.

The decoder defines which source it connects to. Other than defining an IP address and
source type (if required), no special source encoder setup is required.
