Multicast address MPEG-4 encoder 1 (2):
A special IP address (class D address) must be configured for multicast operation
in a multicast-enabled network.
The network must support group IP addresses and the Internet Group
Management Protocol (IGMP). The address range is from 224.0.1.0 to
238.255.255.255.
The multicast address can be the same for multiple encoders. Then however it is
necessary to use a different port in each case so that multiple data streams are
not sent simultaneously over the same port and multicast address.
Enter the multicast address for the particular encoder here if multicast is to be
used.
Port:
In the case of simultaneous data streams from more than one encoder with the
same multicast address the data streams must be assigned to different ports.
Enter the port address for the particular encoder here.
Multicast audio port (G.711):
If audio is to be transmitted in multicast mode, too, the audio data must be
assigned to another port as it is a separate data stream.
Enter the port address for the audio stream here.
Note
A separate audio stream is only transmitted if the corresponding function on
the
Audio stream page is enabled (see page 45).
Multicast packet TTL:
This value determines the "life span" of multicast packets on the network. If
multicast is operated via a router, the value must be greater than 1 to ensure that
the packets are passed on.
