IP MULTICAST
XIV.
IP Multicast is an efficient way of delivering BRIC-Link digital audio streams to multiple locations. This involves
relying on the network to distribute the stream to the locations that require it, rather than creating an independent
stream for each user.
Performing an IP Multicast requires the use of an IP Multicast-capable network. The commercial Internet, with few
exceptions, is not capable of supporting IP Multicast. Some private LANs and WANs are IP Multicast capable.
IP Multicast does not support duplex connections, and only supports a single direction stream. An encoder can not
receive input streams when multicasting. CrossLock is not supported and should be turned off for all IP Multicast
connections.
The following section presupposes that IP Multicast users will be familiar with the basic concepts of setup and
operation of the network, and will thus focus on how to configure BRIC-Link for Multicast mode.
MultIcast ProfIles
To configure remotes for Multicast, first create a profile for either a Multicast Sender or a Multicast Receiver on the
Profile Manager tab.
As shown in Figure 61, when defining a new profile there is the option to choose Multicast as the profile type.
Multicast profiles have fewer options than other profile types, however, and some of the available options will have
no effect (e.g. setting an encoder type on a Multicast receiver has no effect).
