Chapter 6 Configuring the Sender
VideoJet 10 75
Multicasting
In addition to a 1:1 connection between an encoder and a single receiver
(unicast), the VideoJet 10 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 encoder (stream).
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.
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 V2). The address range is from 224.0.1.0 to
239.255.255.255.
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.
Note
You must set the parameters for each encoder (stream) individually.
Multicast streaming
Select the option MPEG-4 to enable multicast streaming. Off disables multicast
streaming.
