Multicasting
In addition to a 1:1 connection between an encoder and a single receiver (uni-
cast), the VIP X2 can enable multiple receivers to receive the video signal from
an encoder simultaneously. The device either duplicates the data stream itself
and then distributes 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 receivers 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.
Note
You must set the parameters for each encoder (video input) and for each
stream individually. The numbering follows the labeling of the video inputs
on the actual unit.
