Multicast configuration
In addition to a 1:1 connection between an encoder and a single receiver
(unicast), the VideoJet 8000 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 eight 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.
The MPEG-2 data transfer protocol is designed for at most one multi-unicast
connection to each encoder. The transparent data connection is maintained by
the first unit. However after about 15 seconds of inactivity, the data connection is
