5.29 Multicasting
In addition to a 1:1 connection between an encoder and a single receiver (unicast), the
VideoJet X20 can enable multiple receivers to receive the video signal from an encoder
simultaneously. The unit either duplicates the data stream itself and then distributes it to
multiple receivers (multi-unicast) or it sends a single data stream to the network, where the
data stream is simultaneously distributed to multiple receivers in a defined group (multicast).
For each encoder (video input) you can enter a dedicated multicast address and port for each
stream. You can switch between the streams by clicking the appropriate tabs.
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 225.0.0.0 to 239.255.255.255.
The multicast address can be the same for multiple streams. However, it will be necessary to
use a different port in each case so that multiple data streams are not sent simultaneously
using the same port and multicast address.
i
NOTICE!
Multicast operation requires a multicast-enabled network that uses the UDP and the Internet
Group Management IGMP protocols. Other group management protocols are not supported.
The TCP protocol does not support multicast connections.

NOTICE!
You must set the parameters for each encoder (video input) and for each stream individually.
The numbering follows the labeling of the video inputs on the actual unit.
