Multicasting
In addition to a 1:1 connection between an encoder and a single receiver (uni-
cast), the VIP X1 can enable multiple receivers to receive the video signal simul-
taneously. The device either duplicates the data stream itself and then distrib-
utes it to multiple receivers (Multi-unicast) or it sends a single data stream to the
network, where the data stream is simultaneously distributed to multiple receiv-
ers in a defined group (Multicast). For each encoder (video input) you can enter
a dedicated multicast address and port for each stream. You can switch
between the streams by clicking the appropriate tabs.
Note
Multicast operation requires a multicast-enabled network that uses the
UDP and the Internet Group Management IGMP protocols. Other group
management protocols are not supported. The TCP protocol does not sup-
port multicast connections.
A special IP address (class D address) must be configured for multicast opera-
tion in a multicast-enabled network.
The network must support group IP addresses and the Internet Group Manage-
ment Protocol (IGMP V2). The address range is from 225.0.0.0 to
239.255.255.255.
The multicast address can be the same for multiple streams. However it will be
necessary to use a different port in each case so that multiple data streams are
not sent simultaneously using the same port and multicast address.
