Enable IGMP querier

You can enable the IGMP querier; this defines the VIP X1600 XF switch as the central

administrator of multicast data traffic in the network. If the VIP X1600 XF is located in an

installation that is some distance away, in which the multicast data is also needed, then this

option can be useful if the connection to the central unit is lost. Once activation is complete,

you must enter the required IP address.

IGMP source IP

Enter the IP address, under which the IGMP queries are answered. The IP address that you

use should be as high as possible and at least higher than that of the standard IGMP querier.

5.40 Advanced Mode: Multicast

In addition to a 1:1 connection between an encoder and a single receiver (unicast), the

module 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.

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.
