VideoJet 1000
Multilink -
Multicast
Enable multicast streaming:
Along with a 1:1 connection between a transmitter and a receiver,
(unicast) the VideoJet 1000 provides the option of connecting a
number of receivers to simultaneously receive the video signal.
This is achieved either by a duplication of the data stream in the unit
with subsequent distribution to a number of receivers (multi-uni-
cast) or by distribution of a single data stream on the network itself
to a number of receivers in a defined group (multicast).
Select here the option On in order to activate the multicast function.
The VideoJet 1000 supports for MPEG-4 the multi-unicast opera-
tion up to a maximum of 5 simultaneously connected receivers. For
MPEG-2 only one multi-unicast connection is possible.
The transparent data connection is maintained from the first unit.
However, after 15 seconds of inactivity the data connection is auto-
matically suspended and another unit can exchange transparent
data with the transmitter.
For multilink operation, the network is not required to be multicast
compatible as the VideoJet 1000 is also multi-unicast compatible.
Duplication of the data in the unit requires considerable processor
Note
Requirement for multicast operation is a multicast compliant net-
work with implementation of the UDP protocol and the IGMP proto-
col. Other group management protocols are not supported. The
TCP protocol does not support any multicast connection.
