The devices support the multi-unicast operation up to a maximum of 5 simultaneously
connected receivers for MPEG-4. The transparent data connection is maintained from the
first unit. However, after 15 seconds of inactivity the data connection is automatically
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
devices are also multi-unicast compatible. Duplication of the data in the unit requires
considerable processor power and, under certain circumstances, leads to limitations in the
picture quality.
Multicast streaming:
Select the option On in order to activate the multicast function. For that purpose a
valid Multicast group IP address has to be entered.
Multicast group IP address:
Before you and use the multicast and the streaming mode in a multicast-compatible
network, you must establish 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. With this field left empty (0.0.0.0) the device is sending in multi-
unicast mode and streaming is not possible.
Multicast port MPEG-4:
This field is read-only and informs about the selected video port. Assignment of port
numbers is done automatically by the software.
Multicast racket TTL:
Here the number of junctions can be entered a data packet can pass within the
network. By setting the parameter you determine the life span of the data packets,
e.g. if multicast is operated over a router the value must be greater than 1 to
guarantee transmission of the packets.
