RD-71 Zixi Setup Guide
Where previous protocols, such as TCP, UDP and RTP have various constraints, Zixi is designed to
overcome protocol limitations for broadcast quality video delivery. There are two Zixi options
available on the RD-71, Zixi-Link and Zixi-Receive.
Zixi-Link is a point to point IP transport using Zixi technology to provide reliable video service over
nondeterministic networks. If the IRD is behind a firewall, port forwarding is required. In this mode,
Zixi parameters are configured on the sender (or Adtec encoder).
Zixi-Rx is used in point to multipoint applications and is combined with a Zixi Broadcaster server. In
ZIXI- Rx mode, the IRD is acting as a client and can therefore bypass the need for firewall forwarding
rules to the IRD. In this mode, all Zixi parameters are configured on the receiver (or RD-71).
Zixi uses a combination of FEC and ARQ to deliver packets. The amount of latency between
end-points, the amount of packet loss incurred between end-points and the bandwidth requirements
of the link all affect how the FEC and latency settings should be configured. These three items should
be taken into consideration when doing initial setup.
Setting up Zixi-Link
To use Zixi-Link, the feature key must be enabled. This may be verified on the Upgrade -> Features
