5.40 Advanced Mode: 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 device 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.
Enable
To enable simultaneous data reception on several receivers you need to activate the multicast
function. To do this, check the box. You can then enter the multicast address.
Multicast Address
Enter a valid multicast address for each stream from the relevant encoder (video input) to be
operated in multicast mode (duplication of the data streams in the network).
With the setting 0.0.0.0 the encoder for the relevant stream operates in multi-unicast mode
(copying of data streams in the unit). The VideoJet X20 supports multi-unicast connections
for up to five simultaneously connected receivers.
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.
i
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.
