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 (i.e. single source to single display) but can be used for up to
four displays.
The source encoder defines the display decoder(s) that the source is available to, but the decoder
chooses which source to display.
RTP provides very low latency which is important for video transport. Unlike other protocols, RTP
packets include a time-stamp. Therefore, if packets are received in the wrong order they can easily be
sorted into the correct order for display, or discarded if the time stamp is ‘out of date’.
However, because RTP is a connection-less protocol, data delivery is not guaranteed. Where data
packets are lost (e.g. due to excessive network traffic) VN-MATRIX carefully manages the data
stream to minimize any image disruption.
