Configuring the Sender
Multicasting
In addition to a 1:1 connection between an encoder and a single receiver
(unicast), the VIP can enable multiple receivers to receive the video signal from
an encoder simultaneously. This is achieved either by duplicating the data stream
in the unit with subsequent distribution to multiple receivers (multi-unicast) or by
distribution of a single data stream over the network to a number of receivers in
a defined group (multicast). A dedicated multicast address and port can be
specified for each of the three encoders.
Note
The prerequisite for multicast operation is a multicast-capable network
using the UDP and IGMP protocols. Other group membership protocols are
not supported. The TCP protocol does not support multicast connections.
When the multicast address is set to 0.0.0.0, the respective encoder operates in
multi-unicast mode (copies the data streams on the unit).
If a valid multicast address is entered the respective encoder operates in the
multicast mode (duplication of the data stream on the network).
Note
Duplication of the data on the unit for multi-unicast connections requires
considerable processor power and, under certain circumstances, leads to
limitations in the picture quality.
Multicast streaming
Select the option MPEG-4 to enable multicast streaming. Off disables multicast
streaming.
