VideoJet
The transparent data link is maintained by the first device as for the
audio link, although the data connection is automatically torn down
after 15 seconds inactivity and another device can exchange trans-
parent data with the receiver.
For the multilink mode, the network does not have to be suitable for
multicast operation, as the
VideoJet
is also multi-unicast compat-
ible. The duplication of the data in the device requires a high com-
puting power and could under certain circumstances lead to a dete-
rioration in the image quality. In this case, you should reduce the
data rate of the transmitter slightly.
With the setting Multilink On and Multicast group IP address =
0.0.0.0 , the device operates in multi-unicast mode (copying the
data streams in the device).
With the setting Multilink On and a valid Multicast group IP
address, the device operates in multicast mode (duplication of the
data streams in the network).
Enable multicast streaming: (transmitter only)
During multicast streaming, the
VideoJet
sends a permanent
data stream to the specified group IP address. No specific receiver
is defined. Each receiver is thus able to receive the data. The trans-
mission rate is determined purely by the transmitter and has to be
set there. For this, a valid multicast group IP address must be set.
Multicast group IP address: (transmitter only)
A precondition for the multicast mode in a multicast-compatible net-
work is the establishment of a special IP address (class D address).
The network must support the establishment of a group IP address
and the Internet Group Management Protocol (IGMP). The address
range is from 224.0.1.0 to 238.255.255.255.
