Multicasting

In addition to a 1:1 connection between an encoder and a single receiver

(unicast), the VideoJet 8008 can enable multiple receivers to receive the video

signal from an encoder simultaneously. This is either done by duplicating the

data stream in the unit and then distributing it to multiple receivers (multi-unicast)

or by distributing an individual data stream in the network itself to multiple

receivers in a defined group (multicast). A dedicated multicast address and port

can be specified for each stream on each of the eight encoders. You can switch

between streams by clicking the associated tabs.

Note

The prerequisite for multicast operation is a multicast-capable network that

uses 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 streams. However, it is then

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.
