This is the recommended transport method for real time video and audio data over an IP network. However, because RTP is a connection-less protocol, data delivery is not guaranteed. Where data packets are lost (such as due to excessive network traffic), the PURE3 algorithm carefully manages the data stream to minimize any image disruption.

NOTE: In figure 3, IP decoder 3 is designated as the system controller.

Unicast RTP

Like multicast RTP, the unicast RTP data transport method uses a real-time variation of the UDP protocol that is connected as shown in figure 4. Unicast RTP differs from multicast RTP in that it is a point-to-point protocol that uses a separate data stream for each decoded display. The VN-Matrix 325 system can support up to four displays (decoders) from one source (encoder), but such a configuration uses four separate data streams and results in four times the network bit rate as a single display (decoder) configuration.

This method can be used in place of multicast RTP, when the network infrastructure does not support or the local IT administration will not allow multicast traffic. Contact the system administrator.

In figure 4, the four streams of data are identified as “RTP1” through “RTP4”.

Figure 4. Typical Unicast RTP Application

As with multicast RTP, it is a connection-less protocol and data delivery is not guaranteed Where data packets are lost (such as due to excessive network traffic), the PURE3 algorithm carefully manages the data stream to minimize any image disruption.

NOTES: In figure 4, the IP encoder is designated as the system controller.

In unicast RTP mode, while the system supports up to 4 simultaneous streams, the rate is dependant on the total aggregated bit rate, which must not exceed 270 Mbs.
