Multicasting
In addition to a 1:1 connection between an encoder and a single receiver
(unicast), the VIP X can enable multiple receivers to receive the video signal
from an encoder simultaneously. This is either done by duplicating the data
stream in the unit and then distributing it to multiple receivers (multi-unicast) or
by distributing an individual data stream in the network itself 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 associated tabs.
Note
The prerequisite for multicast operation is a multicast-capable network that
uses the UDP and IGMP protocols. Other group membership protocols are
not supported. The TCP protocol does not support multicast connections.
A special IP address (class D address) must be configured for multicast
operation in a multicast-enabled network.
The network must support group IP addresses and the Internet Group
Management Protocol (IGMP V3). 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 is then
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
The settings must be made individually for each encoder (video input) and
each stream. The numbering corresponds to the labeling of the video
inputs on the actual unit (VIP X2 only).
